38. The expert from Germany, Chair of the IWG on Rechargeable Energy Storage System (REESS), introduced ECE/TRANS/WP.29/GRSP/2014/26 amending ECE/TRANS/WP.29/GRSP/2014/11 and proposing a draft UN Regulation on safety requirements with respect to the electric power train of vehicles of categories L with a maximum design speed exceeding 6 km/h. The expert from IMMA proposed some amendments (GRSP-56-01) superseding ECE/TRANS/WP.29/GRSP/2014/26. Finally, GRSP adopted ECE/TRANS/WP.29/GRSP/2014/11 as amended by Annex VI to the session report. The secretariat was requested to submit the proposal to WP.29 and AC.1, for consideration and vote at their June 2015 sessions as a new draft UN Regulation on electric vehicles of category L.

39. The expert from Germany, Chair of the IWG on Rechargeable Energy Storage System (REESS) made a presentation (GRSP-55-29) to introduce ECE/TRANS/WP.29/GRSP/2014/11, aimed at proposing a draft UN Regulation on safety requirements with respect to the electric power train of vehicles of categories L₁ with a maximum design speed exceeding 6 km/h. The expert from IMMA proposed some amendments (GRSP-55-07) to ECE/TRANS/WP.29/GRSP/2014/11. The majority of the Contracting Parties (Australia, France, Germany, the Netherlands, Spain, Sweden and the United Kingdom) rejected the introduction of additional provisions (para. 12 of ECE/TRANS/WP.29/GRSP/2014/11) in the text of the draft UN Regulation, to allow Contracting Parties to continue requiring the proof of compliance for post-crash requirements as proposed by the expert from Japan. GRSP referred GRSP-55-25-Rev.1 back to the IWG (including GRSP-55-22 proposed by the expert from Japan) and agreed to resume consideration of this agenda item at its December 2014 session, on the basis of an updated proposal submitted by the IWG. Finally, GRSP agreed to seek consent from WP.29 at its June 2014 session to extend the mandate of the IWG until June 2015.

74. The Chair of GRSP presented ECE/TRANS/WP.29/2015/69. The representative of Germany noted that the document contained square brackets. The World Forum agreed that they should be removed as follows and then be submitted to AC.1 for voting:

75. Through the document, replace “Rechargeable [Electrical] Energy Storage System” to read "Rechargeable Electrical Energy Storage System ".

3. GRSP considered and adopted the agenda (ECE/TRANS/WP.29/GRSP/2014/14 and Add.1) proposed for the fifty-sixth session with the new agenda items 22(g) to 22(i), 23 and 24 as well as the running order (GRSP-56-02). The list of GRSP informal working groups is contained in Annex IX to the session report.

8. The expert from EC introduced ECE/TRANS/WP.29/GRSP/2014/17 and ECE/TRANS/WP.29/GRSP/2014/30, submitted by the Task Force on Bumper Test Area (TF-BTA), a subgroup of the Informal Working Group on global technical regulation No. 9 – Phase 2, and proposing an amendment to the provisions of the bumper test. He explained that the current provisions allow the area to be narrower than intended in the provisions of the UN GTR. He added that ECE/TRANS/WP.29/GRSP/2014/17 was proposing a new method by introducing a practical determination of angle surfaces, to be tested with the FlexPLI, by using a corner gauge. Moreover, he explained that ECE/TRANS/WP.29/GRSP/2014/30 was proposing the introduction of the definition of rigid bumper beam in the test area in addition to the above-mentioned new test method. He finally informed GRSP that a test report on research conducted by EC on this issue was available. The expert from Japan gave a presentation (GRSP-56-03) to support ECE/TRANS/WP.29/GRSP/2014/17. The expert from Korea presented GRSP-56-20 supporting ECE/TRANS/WP.29/GRSP/2014/30. The expert from OICA introduced GRSP-56-30, supporting the new method as proposed by ECE/TRANS/WP.29/GRSP/2014/17, because the test is less sensitive to specific design features and it could be performed without disassembling parts. Moreover, GRSP discussed GRSP-56-38 and GRSP-56-39, superseding respectively ECE/TRANS/WP.29/GRSP/2014/17 and ECE/TRANS/WP.29/GRSP/2014/30.

4. The expert from Germany, on behalf of the Chair of the Informal Working Group (IWG) on the UN Global Technical Regulation (UN GTR) No. 7 – Phase 2, informed GRSP about the work progress of the IWG (GRSP-56-04). He clarified that the IWG had defined a short list of candidate injury criteria to be used in the test of the UN GTR Phase 2. He added that the test pulse had been defined and that good repeatability and reproducibility of the biomechanical rear impact dummy (bioRID) had been achieved. He concluded that a full set of drawings and specifications of the dummy would be incorporated in the draft Addendum 1 of the Mutual Resolution No. 1 (M.R.1), along with the draft amendment to the UN GTR by the December 2015 session of GRSP. The expert from Japan added the presentation of the expert from Germany by introducing the status report of the IWG (GRSP-56-05).

4. The expert from Germany, on behalf of the Chair of the Informal Working Group (IWG) on the UN Global Technical Regulation (UN GTR) No. 7 – Phase 2, informed GRSP about the work progress of the IWG (GRSP-56-04). He clarified that the IWG had defined a short list of candidate injury criteria to be used in the test of the UN GTR Phase 2. He added that the test pulse had been defined and that good repeatability and reproducibility of the biomechanical rear impact dummy (bioRID) had been achieved. He concluded that a full set of drawings and specifications of the dummy would be incorporated in the draft Addendum 1 of the Mutual Resolution No. 1 (M.R.1), along with the draft amendment to the UN GTR by the December 2015 session of GRSP. The expert from Japan added the presentation of the expert from Germany by introducing the status report of the IWG (GRSP-56-05).

26. The expert from Spain introduced GRSP-56-06, to improve dynamic test provisions for CRS and to cope with the presence of load limiters on safety belts used to fix CRS. The expert from EC raised a study reservation and GRSP agreed to resume discussion on this subject at its May 2015 session. In the meantime, the secretariat was requested to distribute GRSP-56-06 with an official symbol at the next session of GRSP.

23. The expert from Spain introduced ECE/TRANS/WP.29/GRSP/2015/5, to improve dynamic test provisions for CRS and to cope with the presence of load limiters on safety belts used to fix CRS. GRSP adopted the proposal not amended and requested the secretariat to submit the proposal for consideration and vote at the November 2015 sessions of WP.29 and AC.3 as draft Supplement 10 to the 04 series of amendments to UN Regulation No. 44.

22. Referring to the discussion under agenda item 7 (see para. 16), the expert from the Netherlands introduced GRSP-56-07, proposing a possible amendment to cover the issue of occupant displacement due to the presence of safety-belt load limiters installed on seats other than front seats. He announced the intention to submit a new proposal on this subject for the May 2015 session of GRSP.

13. The expert from CLEPA introduced a presentation (GRSP-57-25) to explain ECE/TRANS/WP.29/GRSP/2015/16 and GRSP-57-03 (superseding ECE/TRANS/WP.29/GRSP/2015/4) aimed at clarifying the provisions for dynamic testing of rear seat system and advanced restraint system approval. The expert from Japan argued that the proposal was not assessing the air-bag performance through UN Regulation No. 94 because it was addressing other occupants than those seating in lateral frontal positions. The expert from France clarified that the proposal was addressing the concept of restraint systems to other seating positions than front outboard positions. The expert from EC suggested aligning the proposed provisions with those of UN Regulation No. 21, concerning the speed of impact of seating position protected by an air-bag. Accordingly, the expert from CLEPA introduced GRSP-57-28 incorporating the comments received during the discussion. The experts from France and Japan raised study reservations on the proposal. Moreover, the expert from the Netherlands noted that the proposal would affect not only the safety-belt component but also the vehicle. The experts from EC and OICA stated that the proposal should be discussed as a full package with the corresponding amendment to UN Regulation No. 17, namely ECE/TRANS/WP.29/GRSP/2015/14 (see para. 19 below). GRSP agreed to resume discussion on this subject at its December 2015 session and requested the secretariat to distribute GRSP-57-28 with an official symbol.

19. Referring to the discussion held under agenda item 7 (see para. 13 above), the expert from the Netherlands introduced ECE/TRANS/WP.29/GRSP/2015/14, calling for increased energy absorption capabilities on the rear part of seat backs, taking into account the increased forward displacement of the rear occupants restrained by new safety-belts equipped with improved load limiter devices. However, he proposed to defer the discussion at the December 2015 session of GRSP, since the proposal would involve a parallel amendment to UN Regulation No. 16 to extend contact requirements of occupants against rear seats backs. GRSP agreed to resume discussion at its next session on the basis of a new proposal as an outcome of an exchange of views among the experts from the Netherlands, CLEPA, OICA and other interested parties.

33. The expert from France, Chair of the IWG on Enhanced Child Restraint Systems (ECRS), introduced: (i) a presentation to show the main content of the draft 01 series of amendments incorporating provisions for booster seats (GRSP-56-28), (ii) the draft proposal (GRSP-56-08 superseding ECE/TRANS/WP.29/GRSP/2014/28) and (iii) the consolidated version of the UN Regulation, incorporating the proposed amendments (GRSP-56-09). The expert from OICA proposed to reduce the height of the measuring device, to evaluate a universal booster cushion, from 910 mm to 830 mm. He explained that this last value would be less restrictive for vehicle design. The expert from EC informed GRSP that a research test report on child abdominal injuries would be published soon. Accordingly, he raised a study reservation to consider the above-mentioned outcome of research and to complete the assessment of GRSP-56-08. GRSP agreed to resume discussion at its May 2015 session to consider and adopt, as a whole, draft 01 series of amendments and the parallel amendments to UN Regulation No. 16 (see para. 17). Finally, the secretariat was requested to distribute GRSP-56-08 with an official symbol at the next GRSP session.

29. The expert from France, Chair of the IWG on Enhanced Child Restraint Systems (ECRS), introduced a presentation (GRSP-57-22) to show the work progress of the IWG and the main content of draft 01 series of amendments incorporating provisions for booster seats (GRSP-57-20 and GRSP-57-21 superseding ECE/TRANS/WP.29/GRSP/2015/9). He added that for Phase II of the UN Regulation there were still some pending issues such as safety for children in cars on booster cushions without a backrest and geometric definition of the test fixture (gabarit) for booster seats with an integrated backrest. The expert from Germany suggested only the inclusion of booster cushions with backrests in UN Regulation No. 129, while provisions for other kind of boosters should remain for the time being in UN Regulation No. 44 pending a whole revision of this last UN Regulation. The expert from EC endorsed the work of the IWG and he proposed further promotion of the of i-size concept to allow the installation of three ECRS on the same row seat in larger family cars. GRSP agreed to resume discussion at its December 2015 session on this subject awaiting the outcome of the IWG and requested to distribute GRSP-57-20 with an official symbol.

33. The expert from France, Chair of the IWG on Enhanced Child Restraint Systems (ECRS), introduced: (i) a presentation to show the main content of the draft 01 series of amendments incorporating provisions for booster seats (GRSP-56-28), (ii) the draft proposal (GRSP-56-08 superseding ECE/TRANS/WP.29/GRSP/2014/28) and (iii) the consolidated version of the UN Regulation, incorporating the proposed amendments (GRSP-56-09). The expert from OICA proposed to reduce the height of the measuring device, to evaluate a universal booster cushion, from 910 mm to 830 mm. He explained that this last value would be less restrictive for vehicle design. The expert from EC informed GRSP that a research test report on child abdominal injuries would be published soon. Accordingly, he raised a study reservation to consider the above-mentioned outcome of research and to complete the assessment of GRSP-56-08. GRSP agreed to resume discussion at its May 2015 session to consider and adopt, as a whole, draft 01 series of amendments and the parallel amendments to UN Regulation No. 16 (see para. 17). Finally, the secretariat was requested to distribute GRSP-56-08 with an official symbol at the next GRSP session.

29. The expert from France, Chair of the IWG on Enhanced Child Restraint Systems (ECRS), introduced: (i) the status report of the progress of his group (GRSP-55-34-Rev.1) and (ii) the latest update of the draft 01 series of amendments to UN Regulation No. 129 that incorporates provisions for booster seats (GRSP-55-08, superseding ECE/TRANS/WP.29/GRSP/2014/7). The expert from OICA gave a presentation (GRSP-55-35) on a possible child restraint fixture, covering booster seats for children older than 4 years. GRSP agreed to refer GRSP-55-08 back to the IWG and to resume consideration of this agenda item at its December 2014 session on the basis of an updated proposal submitted by the IWG on ECRS.

16. The expert from CLEPA introduced GRSP-56-10 (superseding ECE/TRANS/WP.29/GRSP/2014/27) aimed at clarifying the provisions for dynamic testing of rear seat system and advanced restraint system approval. The expert from France stressed the need to update the test provisions to verify displacement of rear occupants wearing safety-belts equipped with load limiters. He informed GRSP that the New Car Assessment Programme was defining similar provisions by using the fifth percentile female dummy. GRSP agreed to resume discussion on this subject at its May 2015 session and requested the secretariat to distribute GRSP-56-10 with an official symbol.

13. The expert from CLEPA introduced a presentation (GRSP-57-25) to explain ECE/TRANS/WP.29/GRSP/2015/16 and GRSP-57-03 (superseding ECE/TRANS/WP.29/GRSP/2015/4) aimed at clarifying the provisions for dynamic testing of rear seat system and advanced restraint system approval. The expert from Japan argued that the proposal was not assessing the air-bag performance through UN Regulation No. 94 because it was addressing other occupants than those seating in lateral frontal positions. The expert from France clarified that the proposal was addressing the concept of restraint systems to other seating positions than front outboard positions. The expert from EC suggested aligning the proposed provisions with those of UN Regulation No. 21, concerning the speed of impact of seating position protected by an air-bag. Accordingly, the expert from CLEPA introduced GRSP-57-28 incorporating the comments received during the discussion. The experts from France and Japan raised study reservations on the proposal. Moreover, the expert from the Netherlands noted that the proposal would affect not only the safety-belt component but also the vehicle. The experts from EC and OICA stated that the proposal should be discussed as a full package with the corresponding amendment to UN Regulation No. 17, namely ECE/TRANS/WP.29/GRSP/2015/14 (see para. 19 below). GRSP agreed to resume discussion on this subject at its December 2015 session and requested the secretariat to distribute GRSP-57-28 with an official symbol.

14. GRSP noted the decision taken by the World Forum during the June 2014 session to refer back to GRSP ECE/TRANS/WP.29/2014/34 (ECE/TRANS/WP.29/1110, para. 52) to further consider the minimum number of ISOFIX anchorages. The expert from OICA introduced GRSP-56-11-Rev.1, amending ECE/TRANS/WP.29/2014/34, superseding ECE/TRANS/WP.29/GRSP/2014/18 and ECE/TRANS/WP.29/GRSP/2013/15 and addressing the widest range of possible vehicle types and configurations. GRSP adopted ECE/TRANS/WP.29/2014/34 as amended by Annex II to the session report. The secretariat was requested to submit the proposal to WP.29 and AC.1, for consideration and vote at their June 2015 sessions, as draft Supplement 6 to the 07 series of amendments to UN Regulation No. 14.

52. The World Forum agreed to refer ECE/TRANS/WP.29/2014/34 (agenda item 4.6.1) back to GRSP for further consideration.

The decision to postpone was due to a European Commission identification of a possible inconsistency in text with regard to paragraph 5.3.8.2.

48. The expert from Australia introduced GRSP-56-33 (superseding GRSP-56-12), to clarify the scope of the UN Regulation. GRSP adopted the proposal as reproduced in Annex VII of this report. The secretariat was requested to submit the proposal to WP.29 and AC.1, for consideration and vote at their June 2015 sessions, as draft Supplement 1 to the new UN Regulation on Pole Side Impact.

37. The expert from France, Chair of the Frontal Impact IWG, introduced the latest draft amendments of his group (ECE/TRANS/WP.29/GRSP/2014/23) to the draft UN Regulation (ECE/TRANS/WP.29/GRSP/2014/10) on frontal impact with focus on the restraint system, with a thorax compression criterion (ThCC) of 42 mm. He also introduced GRSP-56-36, showing three possible solutions to implement a ThCC of 34 mm for the Hybrid III fifth percentile female dummy as requested by the expert from Japan. The expert from OICA introduced GRSP-56-13-Rev.1 endorsing 42 mm criterion because more balanced to protect both young and elderly people. He added that if a decision would be taken by GRSP to endorse 34 mm, this should be introduced at a later stage as a new series of amendments. The expert from Japan introduced GRSP-56-23-Rev.2 aimed at supporting a ThCC of 34 mm and stated that this value was evidence based for its feasibility. The expert from Sweden stated that she was not in the position to support one of the two values. The expert from Italy was in favour of 42 mm because the ThCC of 34 mm criterion needed further investigation. The expert from EU announced that a test programme (sponsored by the European Union) would start at the beginning of 2015 to investigate on this issue. GRSP agreed to resume discussion at its May 2015 session on the basis of revised proposals to be submitted by the expert from France (including GRSP-56-13-Rev.1 and GRSP-56-23-Rev.2).

37. The expert from France, Chair of the FI IWG, introduced the status report of the group (GRSP-55-43) as well as the latest amendments (GRSP-55-20-Rev.1) to the official proposal (ECE/TRANS/WP.29/GRSP/2014/10) of a new UN Regulation on frontal impact with focus on the restraint system. He added that the IWG focused on two possible scenarios for the threshold of front passenger’s thorax compression criteria:
(a) thorax compression criteria (Thcc) of ≤ 34 mm (considering the injury risk curve for the elderly 5th percentile female);
(b) Thcc ≤ 42 mm (considering the injury risk curve for the 5th percentile female).

38. He asked GRSP for guidance on choosing the scenario to be addressed by the draft UN Regulation. The expert from EC suggested that the first scenario complemented by an additional test (e.g. sled test) with a 95th percentile male dummy. However, the expert from France reminded GRSP that the proposal aimed to reduce the number of tests. The expert from OICA presented a recommendation (GRSP-55-42) for a Thcc ≤ 42 mm to address the 5th percentile female because a Thcc of ≤ 34 mm would only address a limited percentage of the population and because the test tool variations need to be taken into account. He remarked that the higher injury risk for elderly occupants would be considered by a reduced Thcc threshold of 42 mm for the 50th percentile male dummy Hybrid III as was also proposed for UN Regulation No. 94. GRSP finally agreed to resume consideration of this agenda item at its December 2014 session and requested its experts to provide clear guidance on the two above-mentioned scenarios. The secretariat was requested to distribute GRSP-55-20-Rev.1 with an official symbol at the next session of GRSP.

33. The expert from France, Chair of the Frontal Impact IWG, introduced ECE/TRANS/WP.29/GRSP/2015/11 as the final draft UN Regulation on frontal impact with focus on the restraint system, with a thorax compression criterion (ThCC) of 42 mm. He also introduced ECE/TRANS/WP.29/GRSP/2015/12, amended by GRSP-57-01 to require ThCC limit at 34 mm in the 01 series of amendments to the UN Regulation. The expert from Japan suggested also aligning the provisions of the draft UN Regulation with the new Camera-Monitor Systems provisions of UN Regulation No. 46 (see para. 27 above). GRSP noted also the lack of availability of drawings and specification of the 5th percentile female dummy and agreed to insert a footnote as a reminder to interested parties to provide the above mentioned specifications in time for adoption of the draft UN Regulation by WP.29 and AC.1. GRSP considered GRSP-57-29-Rev.1, amending ECE/TRANS/WP.29/GRSP/2015/11 and incorporating all the comments received during the discussion (including GRSP-57-02). Finally, GRSP adopted ECE/TRANS/WP.29/GRSP/2015/11 and ECE/TRANS/WP.29/GRSP/2015/12, both as amended by Annex V to this report. The secretariat was requested to submit for consideration and vote to WP.29 and AC.1 at their November 2015 sessions:
(i) ECE/TRANS/WP.29/GRSP/2015/11 as new draft UN Regulation on frontal impact with focus on the restraint system and
(ii) ECE/TRANS/WP.29/GRSP/2015/12 as 01 series of amendments to the new UN Regulation.

The expert from France introduced GRSP-57-31, for information only, to provide further justification of the biomechanical chest deflection thresholds introduced in the draft UN Regulation.

17. The expert from OICA introduced GRSP-56-14, complemented by GRSP-56-16 reproducing a consolidated text of the amendments proposed [in document GRSP-56-14]. He explained that the proposal was needed to verify which seating positions would allow the installation of the universal booster child restraint system (CRS) proposed by the draft 01 series of amendments to the UN Regulation No. 129 (Enhanced Child Restraint Systems) (see para. 33 below). He clarified that the proposal was aimed at introducing physical [testing], computer simulation or any other means [acceptable to a type-approval authority] to assess [compliance with the child-restraint fixture installation requirements]. The expert from CLEPA introduced GRSP-56-35 to clarify the dimensions of ISOFIX anchorages of the proposed fixture. The expert from OICA argued that GRSP-56-35 could lead to misinterpretation since UN Regulation No. 16 is not dealing with ISOFIX anchorage provisions. The expert from EC noted that the required information on ISOFIX installation (see Annex 17, Appendix 3, tables 1-3 of the UN Regulation No. 16) could be misleading for consumers. The expert from France clarified that the introduction of booster cushion was aimed at improving comfort rather than safety and that the IWG designed provisions for a universal system of this type of CRS as per other CRS. GRSP agreed to refer GRSP-56-14, GRSP-56-16 and GRSP-56-35 to the IWG on CRS for further discussion and agreed to resume consideration on this subject at its May 2015 session.

29. The expert from France, Chair of the frontal impact (FI) IWG, introduced ECE/TRANS/WP.29/GRSP/2014/22 to align the UN Regulation No. 94 with the provisions of new draft UN Regulation (full-width frontal collision) on the protection of older occupants. The proposal received comments from the expert from Germany who proposed to keep the current neck injury criteria. Finally, the expert from France proposed GRSP-56-15-Rev.2, amending ECE/TRANS/WP.29/GRSP/2014/22. GRSP agreed to resume discussion at its May 2015 session and requested the secretariat to distribute GRSP-56-15-Rev.2 with an official symbol.

26. The expert from France, Chair of the frontal impact (FI) IWG, introduced ECE/TRANS/WP.29/GRSP/2015/7 to align the UN Regulation No. 94 with the provisions of new draft UN Regulation (full-width frontal collision) on the protection of older occupants. GRSP adopted ECE/TRANS/WP.29/GRSP/2015/7, as amended by Annex III (including GRSP-57-02) to this report. The secretariat was requested to submit ECE/TRANS/WP.29/GRSP/2015/7 as amended to WP.29 and AC.1, for consideration and vote at their November 2015 sessions as draft 03 series of amendment to UN Regulation No. 94.

17. The expert from OICA introduced GRSP-56-14, complemented by GRSP-56-16 reproducing a consolidated text of the amendments proposed [in document GRSP-56-14]. He explained that the proposal was needed to verify which seating positions would allow the installation of the universal booster child restraint system (CRS) proposed by the draft 01 series of amendments to the UN Regulation No. 129 (Enhanced Child Restraint Systems) (see para. 33 below). He clarified that the proposal was aimed at introducing physical [testing], computer simulation or any other means [acceptable to a type-approval authority] to assess [compliance with the child-restraint fixture installation requirements]. The expert from CLEPA introduced GRSP-56-35 to clarify the dimensions of ISOFIX anchorages of the proposed fixture. The expert from OICA argued that GRSP-56-35 could lead to misinterpretation since UN Regulation No. 16 is not dealing with ISOFIX anchorage provisions. The expert from EC noted that the required information on ISOFIX installation (see Annex 17, Appendix 3, tables 1-3 of the UN Regulation No. 16) could be misleading for consumers. The expert from France clarified that the introduction of booster cushion was aimed at improving comfort rather than safety and that the IWG designed provisions for a universal system of this type of CRS as per other CRS. GRSP agreed to refer GRSP-56-14, GRSP-56-16 and GRSP-56-35 to the IWG on CRS for further discussion and agreed to resume consideration on this subject at its May 2015 session.

31. The expert from Germany introduced GRSP-56-17 and GRSP-56-18 aimed at clarifying the provisions for connectors of electric vehicles. GRSP adopted both proposals, as reproduced in Annex IV to the session report. The secretariat was requested to submit GRSP-56-17 and GRSP-56-18 to WP.29 and AC.1, for consideration and vote at their June 2015 sessions, respectively as: (i) draft Supplement 4 to the 01 series of amendments and as (ii) draft Supplement 2 to the 02 series of amendments to UN Regulation No. 100.

48. The expert from OICA introduced GRSP-55-12 and GRSP-55-13 to clarify provisions for connectors. The expert from Germany agreed with the technical contents of the proposal but suggested a clearer wording. GRSP agreed to resume consideration of this subject at its December 2014 session.

31. The expert from Germany introduced GRSP-56-17 and GRSP-56-18 aimed at clarifying the provisions for connectors of electric vehicles. GRSP adopted both proposals, as reproduced in Annex IV to the session report. The secretariat was requested to submit GRSP-56-17 and GRSP-56-18 to WP.29 and AC.1, for consideration and vote at their June 2015 sessions, respectively as: (i) draft Supplement 4 to the 01 series of amendments and as (ii) draft Supplement 2 to the 02 series of amendments to UN Regulation No. 100.

39. GRSP noted GRSP-56-19, tabled by the expert from the Netherlands to clarify that the adjustment device for the height of the effective upper anchorage (introduced recently for buses) might be part of the anchorage or of the safety-belt requirements. The expert from Spain underlined that these systems should be type approved according to UN Regulation No. 44 if they are intended to restrain children. GRSP agreed to resume discussion at its May 2015 session and requested the secretariat to distribute GRSP-56-19 with an official symbol.

34. GRSP noted ECE/TRANS/WP.29/GRSP/2015/10, tabled by the expert from the Netherlands to clarify that the adjustment device for the height of the effective upper anchorage (introduced recently for buses) might be part of the anchorage or of the safety-belt requirements. The expert from Denmark expressed concerns that the system would be used as a CRS in buses, as has happened in the past because it is cheaper than a real CRS. The expert from France supported in principle the proposal pending further clarifications. GRSP agreed to resume discussion at its December 2015 session on the basis of a revised proposal voluntarily prepared by the expert from the Netherlands.

8. The expert from EC introduced ECE/TRANS/WP.29/GRSP/2014/17 and ECE/TRANS/WP.29/GRSP/2014/30, submitted by the Task Force on Bumper Test Area (TF-BTA), a subgroup of the Informal Working Group on global technical regulation No. 9 – Phase 2, and proposing an amendment to the provisions of the bumper test. He explained that the current provisions allow the area to be narrower than intended in the provisions of the UN GTR. He added that ECE/TRANS/WP.29/GRSP/2014/17 was proposing a new method by introducing a practical determination of angle surfaces, to be tested with the FlexPLI, by using a corner gauge. Moreover, he explained that ECE/TRANS/WP.29/GRSP/2014/30 was proposing the introduction of the definition of rigid bumper beam in the test area in addition to the above-mentioned new test method. He finally informed GRSP that a test report on research conducted by EC on this issue was available. The expert from Japan gave a presentation (GRSP-56-03) to support ECE/TRANS/WP.29/GRSP/2014/17. The expert from Korea presented GRSP-56-20 supporting ECE/TRANS/WP.29/GRSP/2014/30. The expert from OICA introduced GRSP-56-30, supporting the new method as proposed by ECE/TRANS/WP.29/GRSP/2014/17, because the test is less sensitive to specific design features and it could be performed without disassembling parts. Moreover, GRSP discussed GRSP-56-38 and GRSP-56-39, superseding respectively ECE/TRANS/WP.29/GRSP/2014/17 and ECE/TRANS/WP.29/GRSP/2014/30.

No objections to the proposals which are passed for consideration to adopt during the AC.1 session.

10. Finally, the expert from the Republic of Korea introduced GRSP-56-21 for information only. He explained that pedestrian safety was a relevant road safety issue in his country, causing more than 2000 casualties each year and stated the availability of his delegation to prepare proposals concerning tests of active devices to further improve vehicle performances.

10. The experts from the Republic of Korea and OICA introduced a proposal of amendments to UN GTR (GRSP-58-31), to incorporate provisions for active deployable systems in the bonnet area. The expert from OICA clarified that the proposal aimed to use a well-established procedure that had been presented several years ago and that had been recommended to Contracting Parties (CPs) for consideration. The Chair of GRSP informed the Group that he would be able to provide some NHTSA research information on pedestrian safety active systems at the national level to GRSP at its May 2016 session.

11. GRSP agreed to resume consideration on these matters at its May 2016 session and to keep GRSP-58-31 as an informal document for further development.

41. GRSP agreed to defer discussion on this subject to its May 2015 session, due the lack of time and to keep GRSP-56-22, GRSP-56-29 and GRSP-56-34 as a reference in the agenda of the next session.

37. The expert from France, Chair of the Frontal Impact IWG, introduced the latest draft amendments of his group (ECE/TRANS/WP.29/GRSP/2014/23) to the draft UN Regulation (ECE/TRANS/WP.29/GRSP/2014/10) on frontal impact with focus on the restraint system, with a thorax compression criterion (ThCC) of 42 mm. He also introduced GRSP-56-36, showing three possible solutions to implement a ThCC of 34 mm for the Hybrid III fifth percentile female dummy as requested by the expert from Japan. The expert from OICA introduced GRSP-56-13-Rev.1 endorsing 42 mm criterion because more balanced to protect both young and elderly people. He added that if a decision would be taken by GRSP to endorse 34 mm, this should be introduced at a later stage as a new series of amendments. The expert from Japan introduced GRSP-56-23-Rev.2 aimed at supporting a ThCC of 34 mm and stated that this value was evidence based for its feasibility. The expert from Sweden stated that she was not in the position to support one of the two values. The expert from Italy was in favour of 42 mm because the ThCC of 34 mm criterion needed further investigation. The expert from EU announced that a test programme (sponsored by the European Union) would start at the beginning of 2015 to investigate on this issue. GRSP agreed to resume discussion at its May 2015 session on the basis of revised proposals to be submitted by the expert from France (including GRSP-56-13-Rev.1 and GRSP-56-23-Rev.2).

33. The expert from France, Chair of the Frontal Impact IWG, introduced ECE/TRANS/WP.29/GRSP/2015/11 as the final draft UN Regulation on frontal impact with focus on the restraint system, with a thorax compression criterion (ThCC) of 42 mm. He also introduced ECE/TRANS/WP.29/GRSP/2015/12, amended by GRSP-57-01 to require ThCC limit at 34 mm in the 01 series of amendments to the UN Regulation. The expert from Japan suggested also aligning the provisions of the draft UN Regulation with the new Camera-Monitor Systems provisions of UN Regulation No. 46 (see para. 27 above). GRSP noted also the lack of availability of drawings and specification of the 5th percentile female dummy and agreed to insert a footnote as a reminder to interested parties to provide the above mentioned specifications in time for adoption of the draft UN Regulation by WP.29 and AC.1. GRSP considered GRSP-57-29-Rev.1, amending ECE/TRANS/WP.29/GRSP/2015/11 and incorporating all the comments received during the discussion (including GRSP-57-02). Finally, GRSP adopted ECE/TRANS/WP.29/GRSP/2015/11 and ECE/TRANS/WP.29/GRSP/2015/12, both as amended by Annex V to this report. The secretariat was requested to submit for consideration and vote to WP.29 and AC.1 at their November 2015 sessions:
(i) ECE/TRANS/WP.29/GRSP/2015/11 as new draft UN Regulation on frontal impact with focus on the restraint system and
(ii) ECE/TRANS/WP.29/GRSP/2015/12 as 01 series of amendments to the new UN Regulation.

The expert from France introduced GRSP-57-31, for information only, to provide further justification of the biomechanical chest deflection thresholds introduced in the draft UN Regulation.

36. The experts from CLEPA and CI introduced respectively GRSP-56-24 and GRSP-56-27, as a draft brochure for a coordinated information campaign on UN Regulation No. 129. The expert from Germany announced that a similar initiative would be published soon in his country. GRSP agreed to resume discussion on this subject on the basis of a possible common text agreed by interested parties.

49. GRSP considered and adopted GRSP-56-25 to correct information provided by a label permanently affixed on hydrogen containers, as reproduced in Annex VIII to the session report. The secretariat was requested to submit the proposal to WP.29 and AC.1, for consideration and vote at their June 2015 sessions, as draft Supplement 1 to the new UN Regulation on hydrogen and fuel cell vehicles (HFCV).

71(bis). The representative of OICA supported the adoption of the new draft UN Regulation on hydrogen and fuel cell vehicles as submitted to WP.29 and AC.1. He pointed out that this draft also contains post-crash requirements, because it fully transposes UN GTR No. 13 into the 1958 Agreement framework. He added that the normal procedure would have been to insert these provisions in the relevant UN Regulations on frontal and lateral collision, such as UN Regulations Nos. 94 or 95, similar to the approach used for UN Regulation No. 100 (Safety of battery electric vehicles). Therefore, he suggested that GRSP should revise, in a further step, the UN Regulation focusing on safety requirements for the construction and use of HFCV vehicles, while the post-crash requirements would be transferred to the relevant post-crash Regulations under the 1958 Agreement. WP.29 endorsed this approach.

27. GRSP considered GRSP-56-26, tabled by the expert from CLEPA, aimed at updating the references to the European standard on toxicity and flammability of materials used to manufacture CRS. GRSP agreed to resume discussion on this subject at its May 2015 session and requested the secretariat to distribute GRSP-56-26 with an official symbol.

24. The expert from CLEPA introduced ECE/TRANS/WP.29/GRSP/2015/6 through a presentation (GRSP-57-26), aimed at updating the references to the European standard on toxicity and flammability of materials used to manufacture CRS. The expert from Germany informed GRSP about the latest amendments introduced in UN Regulation No. 118 by GRSG, on matters of vertical burning rate much more severe than standard EN 71 mentioned in the proposal. The expert from OICA requested exemption for built-in CRS subject to national/regional legislation (i.e.: EU Regulation on Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH)). GRSP agreed to resume discussion on this subject at its December 2015 session on the basis of a revised proposal tabled by the expert from CLEPA in cooperation with the expert from OICA.

36. The experts from CLEPA and CI introduced respectively GRSP-56-24 and GRSP-56-27, as a draft brochure for a coordinated information campaign on UN Regulation No. 129. The expert from Germany announced that a similar initiative would be published soon in his country. GRSP agreed to resume discussion on this subject on the basis of a possible common text agreed by interested parties.

33. The expert from France, Chair of the IWG on Enhanced Child Restraint Systems (ECRS), introduced: (i) a presentation to show the main content of the draft 01 series of amendments incorporating provisions for booster seats (GRSP-56-28), (ii) the draft proposal (GRSP-56-08 superseding ECE/TRANS/WP.29/GRSP/2014/28) and (iii) the consolidated version of the UN Regulation, incorporating the proposed amendments (GRSP-56-09). The expert from OICA proposed to reduce the height of the measuring device, to evaluate a universal booster cushion, from 910 mm to 830 mm. He explained that this last value would be less restrictive for vehicle design. The expert from EC informed GRSP that a research test report on child abdominal injuries would be published soon. Accordingly, he raised a study reservation to consider the above-mentioned outcome of research and to complete the assessment of GRSP-56-08. GRSP agreed to resume discussion at its May 2015 session to consider and adopt, as a whole, draft 01 series of amendments and the parallel amendments to UN Regulation No. 16 (see para. 17). Finally, the secretariat was requested to distribute GRSP-56-08 with an official symbol at the next GRSP session.

41. GRSP agreed to defer discussion on this subject to its May 2015 session, due the lack of time and to keep GRSP-56-22, GRSP-56-29 and GRSP-56-34 as a reference in the agenda of the next session.

8. The expert from EC introduced ECE/TRANS/WP.29/GRSP/2014/17 and ECE/TRANS/WP.29/GRSP/2014/30, submitted by the Task Force on Bumper Test Area (TF-BTA), a subgroup of the Informal Working Group on global technical regulation No. 9 – Phase 2, and proposing an amendment to the provisions of the bumper test. He explained that the current provisions allow the area to be narrower than intended in the provisions of the UN GTR. He added that ECE/TRANS/WP.29/GRSP/2014/17 was proposing a new method by introducing a practical determination of angle surfaces, to be tested with the FlexPLI, by using a corner gauge. Moreover, he explained that ECE/TRANS/WP.29/GRSP/2014/30 was proposing the introduction of the definition of rigid bumper beam in the test area in addition to the above-mentioned new test method. He finally informed GRSP that a test report on research conducted by EC on this issue was available. The expert from Japan gave a presentation (GRSP-56-03) to support ECE/TRANS/WP.29/GRSP/2014/17. The expert from Korea presented GRSP-56-20 supporting ECE/TRANS/WP.29/GRSP/2014/30. The expert from OICA introduced GRSP-56-30, supporting the new method as proposed by ECE/TRANS/WP.29/GRSP/2014/17, because the test is less sensitive to specific design features and it could be performed without disassembling parts. Moreover, GRSP discussed GRSP-56-38 and GRSP-56-39, superseding respectively ECE/TRANS/WP.29/GRSP/2014/17 and ECE/TRANS/WP.29/GRSP/2014/30.

35. GRSP considered and adopted GRSP-56-31-Rev.1, to prevent installation of y-shaped straps on forward facing CRS, as reproduced in Annex V of the GRSP session report. The secretariat was requested to submit the proposal to WP.29 and AC.1, for consideration and vote at their March 2015 sessions, as draft Supplement 4 to the UN Regulation No. 129 (ECE/TRANS/WP.29/2015/43).

15. The expert from OICA introduced GRSP-56-32, improving the provisions concerning vehicle of category M1 having only one seat row and introducing a new definition of “bucket seat”. The expert from EC stated that this last definition needed further discussion. The expert from Japan in principle disagreed on the proposed limit of 140 for the power to mass ratio index to exempt vehicles, exceeding that value, from having ISOFIX positions. Finally, GRSP requested the secretariat to distribute GRSP-56-32 with an official symbol at its May 2015 session.

12. The expert from OICA introduced ECE/TRANS/WP.29/GRSP/2015/3, aimed at improving the provisions concerning vehicles of category M1 having only one seat row and introducing a new definition of “bucket seat”. The expert from the Netherlands noted that ECE/TRANS/WP.29/2015/46, submitted for consideration and voting at the June 2015 session of WP.29 was amending the same provisions and that further proposal of amendments would create confusion. The expert from OICA withdrew ECE/TRANS/WP.29/GRSP/2015/3. Finally, GRSP agreed to resume discussion on this subject at its December 2015 session and requested the secretariat to keep ECE/TRANS/WP.29/GRSP/2015/3 as a reference in the agenda of that session.

48. The expert from Australia introduced GRSP-56-33 (superseding GRSP-56-12), to clarify the scope of the UN Regulation. GRSP adopted the proposal as reproduced in Annex VII of this report. The secretariat was requested to submit the proposal to WP.29 and AC.1, for consideration and vote at their June 2015 sessions, as draft Supplement 1 to the new UN Regulation on Pole Side Impact.

41. GRSP agreed to defer discussion on this subject to its May 2015 session, due the lack of time and to keep GRSP-56-22, GRSP-56-29 and GRSP-56-34 as a reference in the agenda of the next session.

17. The expert from OICA introduced GRSP-56-14, complemented by GRSP-56-16 reproducing a consolidated text of the amendments proposed [in document GRSP-56-14]. He explained that the proposal was needed to verify which seating positions would allow the installation of the universal booster child restraint system (CRS) proposed by the draft 01 series of amendments to the UN Regulation No. 129 (Enhanced Child Restraint Systems) (see para. 33 below). He clarified that the proposal was aimed at introducing physical [testing], computer simulation or any other means [acceptable to a type-approval authority] to assess [compliance with the child-restraint fixture installation requirements]. The expert from CLEPA introduced GRSP-56-35 to clarify the dimensions of ISOFIX anchorages of the proposed fixture. The expert from OICA argued that GRSP-56-35 could lead to misinterpretation since UN Regulation No. 16 is not dealing with ISOFIX anchorage provisions. The expert from EC noted that the required information on ISOFIX installation (see Annex 17, Appendix 3, tables 1-3 of the UN Regulation No. 16) could be misleading for consumers. The expert from France clarified that the introduction of booster cushion was aimed at improving comfort rather than safety and that the IWG designed provisions for a universal system of this type of CRS as per other CRS. GRSP agreed to refer GRSP-56-14, GRSP-56-16 and GRSP-56-35 to the IWG on CRS for further discussion and agreed to resume consideration on this subject at its May 2015 session.

37. The expert from France, Chair of the Frontal Impact IWG, introduced the latest draft amendments of his group (ECE/TRANS/WP.29/GRSP/2014/23) to the draft UN Regulation (ECE/TRANS/WP.29/GRSP/2014/10) on frontal impact with focus on the restraint system, with a thorax compression criterion (ThCC) of 42 mm. He also introduced GRSP-56-36, showing three possible solutions to implement a ThCC of 34 mm for the Hybrid III fifth percentile female dummy as requested by the expert from Japan. The expert from OICA introduced GRSP-56-13-Rev.1 endorsing 42 mm criterion because more balanced to protect both young and elderly people. He added that if a decision would be taken by GRSP to endorse 34 mm, this should be introduced at a later stage as a new series of amendments. The expert from Japan introduced GRSP-56-23-Rev.2 aimed at supporting a ThCC of 34 mm and stated that this value was evidence based for its feasibility. The expert from Sweden stated that she was not in the position to support one of the two values. The expert from Italy was in favour of 42 mm because the ThCC of 34 mm criterion needed further investigation. The expert from EU announced that a test programme (sponsored by the European Union) would start at the beginning of 2015 to investigate on this issue. GRSP agreed to resume discussion at its May 2015 session on the basis of revised proposals to be submitted by the expert from France (including GRSP-56-13-Rev.1 and GRSP-56-23-Rev.2).

46. The expert from Germany introduced GRSP-56-37 to inform GRSP on the activity concerning the terms of reference and the work plan for the IWG to harmonize the specifications of the three-dimensional H-point machine.

8. The expert from EC introduced ECE/TRANS/WP.29/GRSP/2014/17 and ECE/TRANS/WP.29/GRSP/2014/30, submitted by the Task Force on Bumper Test Area (TF-BTA), a subgroup of the Informal Working Group on global technical regulation No. 9 – Phase 2, and proposing an amendment to the provisions of the bumper test. He explained that the current provisions allow the area to be narrower than intended in the provisions of the UN GTR. He added that ECE/TRANS/WP.29/GRSP/2014/17 was proposing a new method by introducing a practical determination of angle surfaces, to be tested with the FlexPLI, by using a corner gauge. Moreover, he explained that ECE/TRANS/WP.29/GRSP/2014/30 was proposing the introduction of the definition of rigid bumper beam in the test area in addition to the above-mentioned new test method. He finally informed GRSP that a test report on research conducted by EC on this issue was available. The expert from Japan gave a presentation (GRSP-56-03) to support ECE/TRANS/WP.29/GRSP/2014/17. The expert from Korea presented GRSP-56-20 supporting ECE/TRANS/WP.29/GRSP/2014/30. The expert from OICA introduced GRSP-56-30, supporting the new method as proposed by ECE/TRANS/WP.29/GRSP/2014/17, because the test is less sensitive to specific design features and it could be performed without disassembling parts. Moreover, GRSP discussed GRSP-56-38 and GRSP-56-39, superseding respectively ECE/TRANS/WP.29/GRSP/2014/17 and ECE/TRANS/WP.29/GRSP/2014/30.

9. GRSP endorsed GRSP-56-39, but did not support GRSP-56-38. The secretariat was requested to distribute GRSP-56-39 with an official symbol for consideration at its May 2015 session. It was agreed that this proposal would be discussed further by the Contracting Parties under the 1998 Agreement and by GRSP at its next session as a full package with: (i) an updated draft proposal of Phase 2 of the UN GTR (ECE/TRANS/WP.29/GRSP/2014/15) and (ii) an updated final report of the IWG (ECE/TRANS/WP.29/GRSP/2014/16).

5. The expert from Germany, on behalf of the Chair of the IWG, informed GRSP that the group had met on 24 November 2017. As a result of this meeting, he was able to introduce the consolidated text of draft Amendment 2 to UN GTR No. 9 (GRSP-62-15-Rev.1), incorporating: (a) the flexible pedestrian legform impactor (FlexPLI) (ECE/TRANS/WP.29/GRSP/2014/15), (b) the new bumper test area (ECE/TRANS/WP.29/GRSP/2015/2) and the removal of the study reservation on the Injury Assessment Values (IARVs) (ECE/TRANS/WP.29/GRSP/2017/3). He also introduced the progress report of the IWG (GRSP-62-16) superseding ECE/TRANS/WP.29/GRSP/2014/16. GRSP was not yet in the position to adopt the proposal and requested the secretariat to distribute GRSP-62-15-Rev.1 and GRSP-62-16 with official symbols for final review at its May 2018 session. Moreover, GRSP requested the IWG to draft Addendum 3 to Mutual Resolution No. 1 of the 1958 and the 1998 Agreements to provide drawings and technical specifications of the FlexPLI. GRSP also requested the IWG to liaise with the FlexPLI manufacturer to have free availability of the above-mentioned technical information. Finally, GRSP agreed to seek endorsement from WP.29 and the Executive Committee of the 1998 Agreement (AC.3) at their March 2018 sessions to extend the mandate of the IWG by one year.

8. The expert from EC introduced ECE/TRANS/WP.29/GRSP/2014/17 and ECE/TRANS/WP.29/GRSP/2014/30, submitted by the Task Force on Bumper Test Area (TF-BTA), a subgroup of the Informal Working Group on global technical regulation No. 9 – Phase 2, and proposing an amendment to the provisions of the bumper test. He explained that the current provisions allow the area to be narrower than intended in the provisions of the UN GTR. He added that ECE/TRANS/WP.29/GRSP/2014/17 was proposing a new method by introducing a practical determination of angle surfaces, to be tested with the FlexPLI, by using a corner gauge. Moreover, he explained that ECE/TRANS/WP.29/GRSP/2014/30 was proposing the introduction of the definition of rigid bumper beam in the test area in addition to the above-mentioned new test method. He finally informed GRSP that a test report on research conducted by EC on this issue was available. The expert from Japan gave a presentation (GRSP-56-03) to support ECE/TRANS/WP.29/GRSP/2014/17. The expert from Korea presented GRSP-56-20 supporting ECE/TRANS/WP.29/GRSP/2014/30. The expert from OICA introduced GRSP-56-30, supporting the new method as proposed by ECE/TRANS/WP.29/GRSP/2014/17, because the test is less sensitive to specific design features and it could be performed without disassembling parts. Moreover, GRSP discussed GRSP-56-38 and GRSP-56-39, superseding respectively ECE/TRANS/WP.29/GRSP/2014/17 and ECE/TRANS/WP.29/GRSP/2014/30.

9. GRSP endorsed GRSP-56-39, but did not support GRSP-56-38. The secretariat was requested to distribute GRSP-56-39 with an official symbol for consideration at its May 2015 session. It was agreed that this proposal would be discussed further by the Contracting Parties under the 1998 Agreement and by GRSP at its next session as a full package with: (i) an updated draft proposal of Phase 2 of the UN GTR (ECE/TRANS/WP.29/GRSP/2014/15) and (ii) an updated final report of the IWG (ECE/TRANS/WP.29/GRSP/2014/16).

6. The expert from EC introduced GRSP-57-15-Rev.1, superseding ECE/TRANS/WP.29/GRSP/2015/2, and proposing the introduction of the definition of rigid bumper beam in the test area in addition to the proposed bumper test method with the flexible pedestrian legform impactor (FlexPLI). The expert from OICA introduced GRSP-57-12, explaining that the new definition of the test area leads to test bumper surfaces at an angle greater than the justified 30°. He added that this might result in occurrence of total and relative rotation of the leg as well as sliding along the surface and produce non-repeatable data. The expert from the United States of America requested a study reservation on this proposal based on the above concern regarding the test tool’s repeatability at an impact angle of 30 degrees or higher. She announced that results of this research would be available at the December 2015 session of GRSP. The expert from Japan proposed to share data from his country to be included in the cost benefit analysis. GRSP agreed to resume discussion on this subject and on the pending issues of the proposal of amendments to the UN GTR (ECE/TRANS/WP.29/GRSP/2014/15, ECE/TRANS/WP.29/GRSP/2014/16 and ECE/TRANS/WP.29/GRSP/2015/2) at its December 2015 session.

32. Referring to the decision held under agenda item 3(a) (see paragraphs 8. and 9.), GRSP endorsed in principle GRSP-56-41 (superseding ECE/TRANS/WP.29/GRSP/2014/31, ECE/TRANS/WP.29/GRSP/2014/32 and GRSP-56-40), introducing the new bumper test method and the definition of bumper beam. GRSP agreed to resume discussion at its May 2015 session to define proper transitional provisions and decide whether to adopt the proposal either as a new series of amendments or as a supplement. Finally, the secretariat was requested to distribute GRSP-56-41 with an official symbol at the next session of GRSP.

32. Referring to the decision held under agenda item 3(a) (see paragraphs 8. and 9.), GRSP endorsed in principle GRSP-56-41 (superseding ECE/TRANS/WP.29/GRSP/2014/31, ECE/TRANS/WP.29/GRSP/2014/32 and GRSP-56-40), introducing the new bumper test method and the definition of bumper beam. GRSP agreed to resume discussion at its May 2015 session to define proper transitional provisions and decide whether to adopt the proposal either as a new series of amendments or as a supplement. Finally, the secretariat was requested to distribute GRSP-56-41 with an official symbol at the next session of GRSP.

28. Referring to the decision held under agenda item 3(a) (see para. 6.), the expert from EC introduced GRSP-57-16-Rev.1 (superseding ECE/TRANS/WP.29/GRSP/2015/8, GRSP-57-12 and GRSP-57-13), introducing the new bumper test method and the definition of bumper beam and meeting the needs expressed by the expert from OICA at the December 2014 session of GRSP. GRSP adopted ECE/TRANS/WP.29/GRSP/2015/8, as amended by Annex IV (including GRSP-57-16-Rev.1) to this report. The secretariat was requested to submit the proposal to WP.29 and AC.1 for consideration and vote at their November 2015 sessions, as draft 02 series of amendments to UN Regulation No. 127.

18. GRSP noted GRSP-56-42 (for information only) tabled by the expert from Korea and aimed at introducing the mandatory fitting of safety-belt reminders also for rear seats. GRSP agreed to resume discussion on this subject at its May 2015 session and to keep ECE/TRANS/WP.29/GRSP/2012/25 in the agenda for possible discussion at its next sessions.
