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.

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.

27. The expert from the Netherlands introduced ECE/TRANS/WP.29/GRSG/2015/13 aligning the provisions of UN Regulation No. 94 with the new provisions on Camera-Monitor Systems provisions in UN Regulation No. 46 (Devices for indirect vision). GRSP adopted the proposal, as reproduced by Annex III (including GRSP-57-02), and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their November 2015 sessions, as draft Supplement 6 to the 02 series of amendments and as part of (see para. 26) the draft 03 series of amendments to UN Regulation No. 94.

41. GRSP noted the request of WP.29 (WP.29-165-16) to change the definition of Rechargeable Energy Storage System (REESS) in Rechargeable Electric Energy Storage System and maintaining the same acronym REESS in all UN Regulations under GRSP responsibilities (where REESS is present). It was noted that this was needed to avoid confusion with Rechargeable Storage Systems of different kinds (such as mechanical storage systems). Accordingly, GRSP adopted GRSP-57-02 as reproduced in Annex VI of the report. The secretariat was requested to submit it to the November 2015 session of WP.29 and AC.1 as draft: (i) Supplement 4 to the 04 series of amendments to Regulation No. 12 (Steering mechanism), (ii) as part of (see para. 27) Supplement 6 to the 02 series of amendments to Regulation No. 94 (Frontal collision protection), (iii) 03 series of amendments to Regulation No. 94 (ECE/TRANS/WP.29/GRSP/2015/7) (see para. 26), (iv) Supplement 5 to the 03 series of amendments to Regulation No. 95 (Lateral collision protection), (v) Supplement 3 to the 02 series of amendments to Regulation No. 100 (Battery electric vehicle safety), (vii) amendment to draft Regulation on electric vehicles of category L (ECE/TRANS/WP.29/2015/69) and (viii) amendment to draft Regulation on uniform provisions for the approval of passenger cars in the event of a frontal collision with focus on the restraint system (ECE/TRANS/WP.29/GRSP/2015/11) (see para. 33).

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.

25. Finally, GRSP agreed to refer discussion on ECE/TRANS/WP.29/GRSP/2015/18 and GRSP-58-35 to agenda item 11.

26. The expert from CLEPA introduced ECE/TRANS/WP.29/GRSP/2015/18, aimed at clarifying the provisions for dynamic testing of the rear seat restraint systems. She explained that the proposal aimed at updating requirements that were originally designed for seating positions that did not yet require three-point safety-belts; she added that the situation had developed with the introduction of load limiters that allowed for further displacement of occupants. Comments from GRSP experts on the proposal were incorporated into GRSP-58-35 during discussion. The expert from the Netherlands introduced ECE/TRANS/WP.29/GRSP/2015/27 that was also linked to ECE/TRANS/WP.29/GRSP/2015/18 because the of displacement of occupants due to safety belt load limiters that were installed on seats other than front seats. He explained that the proposal needed corresponding amendments to UN Regulations Nos. 21, 25 and 80. The expert from OICA argued that the proposal should address just those seating positions that needed energy absorption requirements. The expert from CLEPA also underlined the need to focus the energy dissipation tests on the parts of back seats where actual impacts occur.

27. Finally, GRSP agreed to establish a group of interested experts, led by the expert from the Netherlands, on new restraint system technology to develop provisions on this matter for all the relevant UN Regulations. GRSP agreed to resume discussion on this subject at its May 2016 session and to refer ECE/TRANS/WP.29/GRSP/2015/18, ECE/TRANS/WP.29/GRSP/2015/27 and GRSP-58-35 to the group of interested experts.

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.

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.

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).

69. Agenda item 4.13.1, new Regulation on frontal impact, ECE/TRANS/WP.29/2015/105, insert the following amendment to read:
Paragraph 5.2.8.2, amend the term “0.5 litres” to read “5.0 litres”.

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.
