1. The Working Party on Passive Safety (GRSP) held its fifty-fifth session in Geneva from 19 to 23 May 2014, chaired by Ms. M. Versailles (United States of America). Experts from the following countries participated in the work following Rule 1(a) of the Rules of Procedure of the World Forum for Harmonization of Vehicle Regulations (WP.29) (TRANS/WP.29/690, Amend.1 and Amend.2):

Australia; Belgium; Brazil; Czech Republic; China; France; Germany; Hungary; India; Italy; Japan; Netherlands; Norway; Republic of Korea; Russian Federation; South Africa; Spain; Sweden; Turkey; United Kingdom of Great Britain and Northern Ireland (United Kingdom) and United States of America. An expert from the European Commission (EC) participated.

Experts from the following non-governmental organizations participated:

Consumers International (CI); European Association of Automotive Suppliers (CLEPA); International Motorcycle Manufacturers Association (IMMA) and International Organization of Motor Vehicle Manufacturers (OICA). Upon the special invitation of the Secretariat, the session was also attended by an expert from the Association of the European Bicycle Industry (COLIBI) and the Association of the European Two-Wheeler Parts and Accessories Industries (COLIPED).

2. The informal documents distributed during the session are listed in Annex I to the GRSP 55th session report.

3. GRSP considered and adopted the agenda (ECE/TRANS/WP.29/GRSP/2014/1 and Add.1) proposed for the fifty-fifth session with the new agenda items 23(e) to 23(k) and 24 as well as the running order (GRSP-55-05). The list of GRSP informal working groups is contained in Annex VIII to the GRSP 55th session report.

GRSP-55-05 | Running order of the agenda for the 55th GRSP session

GRSP/2014/1 | Annotated provisional agenda for the 55th GRSP session

GRSP/2014/1/Add.1 | Addendum 1 to the annotated provisional agenda for the 55th GRSP session

4. The expert from the United Kingdom, 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. He clarified that notwithstanding the progress of the last meeting held in February 2014, outstanding points remained, i.e. on injury criteria. He added that the next meeting had been scheduled on early September 2014, in Berlin. He stated that the IWG had suggested that the issue of the head restraint height would be resolved by GRSP rather than the IWG. He finally announced that a revised official proposal for a UN GTR would be submitted by the IWG at the December 2014 session of GRSP as well as a final draft addendum to the Mutual Resolution No. 1 (M.R.1), to incorporate the Biofidelic Rear Impact Dummy (BioRID II).

5. Finally, GRSP agreed to resume consideration of the draft UN GTR (ECE/TRANS/WP.29/GRSP/2013/24) on the basis of final proposals submitted by the IWG and to resume discussion on the height of the head restraints (ECE/TRANS/WP.29/GRSP/2013/17) at its December 2014 session.

GRSP/2013/17 | Proposal for Amendment 1 to GTR No. 7 Proposal to specify a head restraint height between 720 mm and 830 mm pursuant to the work on phase 2 of GTR No. 7 which includes a new method for measuring the effective height of head restraints.

GRSP/2013/24 | Draft amendment 1 (Phase 2) to GTR No. 7 Working draft of the phase 2 revisions to the global technical regulation on head restraints provided to the GRSP at its December 2013 session for informational purposes only.

6. GRSP noted that the Administrative Committee of the 1998 Agreement (AC.3) at its March 2014 referred WP.29-162-03 to GRSP, concerning the Injury Assessment References Values (IARVs) for the flexible lower legform (FlexPLI) to bumper test, of the proposal for amendments to the UN GTR. It was also noted that referring this document back to GRSP, the establishment of the UN GTR would be delayed until an agreement on the IARVs would be reached by GRSP (ECE/TRANS/WP.29/1108, paras. 91 and 92). Therefore, the expert of the United States of America introduced GRSP-55-36, suggesting to amend the preamble of the draft UN GTR to allow Contracting Parties to choose appropriate values based on their cost and benefit studies and the existing injury risk curves. He concluded that establishing premature values, without the research results would introduce risks of dis-harmonization. The expert from Germany, supported by the expert from OICA, argued that this approach would not be, however, the most favourable one for harmonization. He suggested to put the development of UN GTR No. 9 – Phase 2 on hold until the expert from the United States of America completed his research and to concentrate the work on the corresponding UN Regulation No. 127.

7. Finally, GRSP agreed to resume discussion at its December 2014 session, based on further research results and requested the secretariat to distribute GRSP-55-40, GRSP-54-33-Rev.2 (draft UN GTR) and GRSP-54-34-Rev.1 (draft final report of the IWG) with official symbols.

GRSP-55-36 | Comments from the United States on the draft Amendment 2 to GTR No. 9 The draft Amendment 2 to GTR No. 9 proposes to establish the new FlexPLI impactor as the single harmonized tool for lower leg impact tests. The amendment also proposes injury assessment reference values (IARV) to go with the FlexPLI. The US, however, has consistently expressed concerns that the proposed injury thresholds and IARV have not been validated as appropriate for the American car fleet. Therefore, the US proposes to have 'recommended' IARV included in the preamble to Amendment 2 while allowing governments the freedom to use whatever IARV/performance thresholds they deem appropriate until such criteria can be fully validated.

8. GRSP noted a presentation (GRSP-55-09), tabled by the expert from OICA, showing new examples of how the current headform test method created issues for the determination of the test zone or the test execution. The expert from the United States of America announced that the Notice of Proposal of Regulation Making (NPRM), aimed at transposing as a first step UN GTR No. 9 Phase 1, would be published in 2014.

GRSP-55-09 | Pedestrian Protection: Definition of the Measuring Point Presentation of an assessment of 2D vs. 3D impactor positioning methods.

9. Moreover, the expert from OICA gave a presentation (GRSP-55-40) on the work progress of the Task Force Bumper Test Area (TF-BTA), a subgroup of the IWG on UN GTR No. 9 – Phase 2 and proposing an amendment (GRSP-55-41) to the provisions of the bumper test.

10. GRSP agreed to resume consideration of this agenda item at its December 2014 session, awaiting the outcome of research on this issue from Contracting Parties concerned. GRSP requested the secretariat to distribute GRSP-55-41 with an official symbol at its next session. Finally, it was agreed to consider GRSP-55-24 under agenda item 17.

GRSP-55-24 | Proposal of amendment to documents GRSP/2014/2 and GRSP/2014/5 Proposal to clarify figure 11 in the draft amendments to GTR No. 9 by substituting the description "Figure 11: Example of marking of HIC 1000 zone and HIC 1700 zone".

GRSP-55-40 | Status of the Task Force on Bumper Test Area

GRSP-55-41 | Proposal for Amendment [x] to global technical regulation No. 9 Draft text prepared by the Task Force Bumper Test Area (TF-BTA), a subgroup of the Informal Working Group on gtr No. 9 – Phase 2.

11. GRSP noted that no new information were provided by the co-sponsors of the UN GTR No. 13 (Germany, Japan and United States of America) on a proposal of authorization to develop Phase 2 of the UN GTR, including the terms of references (ToR) and a mandate for a new IWG. GRSP agreed to remove this item from the agenda of its December 2014 session, awaiting further information.

12. The Chair of GRSP, also chairing of the IWG on harmonization of side impact dummies, reported on the work progress of the IWG. She informed GRSP about an upcoming meeting with ISO (23 May 2014) to reach an agreement on the availability of the full set of drawings and specifications including the user manual of the 50th percentile World Side Impact dummy (WorldSID) for the final draft addendum to the M.R.1. She also informed GRSP that the 5th percentile female WorldSID dummy needed to be redesigned more than expected.

13. The expert from the United States of America gave an update on the activity of the IWG on Electric Vehicle Safety (EVS) UN GTR. The last meeting was held in Washington, D.C. on 13-15 May 2014 where participants continued to share information on research and rulemaking activities as in the United States of America and Canada. He clarified that these activities would provide regulatory recommendations for the draft UN GTR, its test procedures as well as supporting technical data. He mentioned that the IWG had been briefed on the progress of the seven Task Force (TF) groups set up to analyse and research specific topics, such as State of Charge (SOC), fire resistance, water immersion, etc. He announced that the IWG agreed: (i) to develop the UN GTR in one phase and (ii) to establish a new TF group to investigate on possible extension of the UN GTR scope to include buses and trucks. He finally invited the OICA experts from the bus and heavy truck manufacturers to attend GRSP and to participate in the activities of this new TF group.

14. No new information was provided for this agenda item and GRSP agreed to delete it from the agenda of its further sessions.

15. GRSP resumed consideration on a proposal tabled by the expert from Germany (ECE/TRANS/WP.29/GRSP/2014/13), aimed at ensuring that no vehicle occupants would be unintentionally fully locked inside the vehicle. The expert from OICA, in cooperation with the expert from France, introduced GRSP-55-10-Rev.3 on allowing occupants to manually activate, from the interior of the vehicle, an acoustic warning in case the ignition is switched off. Finally, GRSP adopted ECE/TRANS/WP.29/GRSP/2014/13, as amended by Annex II to the GRSP 55th session report. The secretariat was requested to submit the proposal to WP.29 and AC.1, for consideration and vote at their November 2014 sessions as draft 04 series of amendments to the UN Regulation.

GRSP-55-10/Rev.3 | Proposal for the 04 series of amendments to Regulation No. 11 Proposal to require that a horn or other acoustic signalling system can be activated from within a parked vehicle when in the fully locked mode and to set the transition period through 1 September 2016 for meeting the new requirement.

GRSP/2014/13 | Proposal for the 04 series of amendments to Regulation No. 11 Certain anti-theft systems fully lock every door and window in a vehicle and also deactivate interior unlock controls. This can lead to a situation where an occupant can be locked inside a vehicle with no means of exit save to break a window. This proposal would introduce provisions for the safety and protection of road vehicle occupants in case of the installation of such a full locking system.

16. GRSP resumed consideration of paragraph 5.3.8.2. of ECE/TRANS/WP.29/GRSP/2013/15, concerning exemption to the mandatory installation of an ISOFIX position anchorages in vehicles with one seat row. However, the expert from OICA showed (GRSP-55-32) differences between sport cars unfitted for the transport of children and conventional cars with one seat row. Therefore, he proposed GRSP-55-31 which introduces a geometric criteria (R- point height above the ground less than 450 mm) to exempt such sport cars. The expert from Germany raised a study reservation on this proposal. GRSP agreed to resume consideration of this subject at its December 2014 session and requested the secretariat to distribute GRSP-55-31 with an official symbol.

GRSP-55-31 | Proposal for Supplement 7 to the 07 series of amendments to Regulation No. 14 The current text of UN R14 requires the installation of two ISOFIX anchorages in a vehicle. Vehicles with only one seat row are exempted from this requirement. This proposal refines the previous German proposal to introduce provisions for at least one set of ISOFIX anchorages in vehicles having only one seat row or having several seat rows with only one seat per row (document GRSP-53-11) which modified the proposal for Supplement 6 to the 07 series of amendments (document GRSP/2013/15).

GRSP-55-32 | Extension of ISOFIX-fitment to City-Cars: Classification by using the height of R-point above ground Slide illustrating vehicle types intended to be exempted from the ISOFIX requirements of UN R14 under the proposed classification according to R-point measurement.

GRSP/2013/15 | Proposal for Supplement 6 to the 07 series of amendments to Regulation No. 14 The current text of UN R14 requires the installation of two ISOFIX anchorages in a vehicle. Vehicles with only one seat row are exempted from this requirement. This proposal introduces provisions for at least one set of ISOFIX anchorages in vehicles having only one seat row or having several seat rows with only one seat per row.

17. GRSP did not resume discussion on ECE/TRANS/WP.29/GRSP/2012/25 and GRSP-54-03, awaiting the adoption of the amendment to the 1958 Agreement and the future requirements on transitional provisions.

GRSP-54-03 | Proposal for Supplement 6 to the 06 series of amendments to Regulation No. 16 Proposal based on document GRSP/2012/25 (proposal drafted by the secretariat to consolidate the transitional provisions of UN R16 as a basis for a discussion on simplifying and correcting the text) to consolidate the transitional provisions of UN R16.

GRSP/2012/25 | Proposal for Supplement 3 to the 06 series of amendments to Regulation No. 16 Pursuant to discussions from the 44th GRSP session, the secretariat has drafted this proposal to consolidate the transitional provisions of UN R16 as a basis for a discussion on simplifying and correcting the current text of the regulation.

18. GRSP resumed consideration on a proposal tabled by the expert from CLEPA (GRSP-55-15), aimed at introducing provisions to define the moment of inertia of the luggage impact test. The expert from Japan reminded GRSP of his previous proposal (GRSP-54-20) to regulate only the lower limit of the moment of inertia of the test blocks and proposed further consultation with the expert from CLEPA. Finally, GRSP agreed to resume discussion at its December 2014 session and requested the secretariat to distribute GRSP-55-15 with an official symbol.

GRSP-54-20 | Japan proposal for Supplement 3 to the 08 series of amendments to Regulation No. 17 In document GRSP-54-04, CLEPA proposed changes to improve the reproducibility of the luggage impact test described in annex 9 of UN R17. Japan proposes to specify only the minimum moment of inertia in the test (where CLEPA proposed a minimum-maximum range.

GRSP-55-15 | Proposal for Supplement 3 to the 08 series of amendments to UN Regulation No. 17 Proposal to define the moment of intertia in the luggage-impact test as "0.3 ± 0.05 kgm² (around all 3 principal axis of inertia of the luggage blocks)". UN R17 presently lacks such a definition, resulting in variations in trajectory and behavior of the luggage cubes before and after impact.

19. The expert from Germany introduced GRSP-55-19 to extend the prohibition of installation of side-facing seats to all categories of commercial vehicles (N). The expert from Turkey raised a study reservation and the expert from OICA argued that this extension should be carefully examined for special vehicles (e.g. ambulances, hearses). GRSP agreed to resume consideration of this agenda item at its December 2014 session and requested the secretariat to distribute GRSP-55-19 with an official symbol.

GRSP-55-19 | Proposal for Supplement 2 to the 04 series of amendments to Regulation No. 17 Proposal to clarify the prohibition of side-facing seats on category N vehicles and close the related loophole in the current text in this regard.

20. Finally GRSP considered GRSP-55-30-Rev.1, proposing editorial amendments to the UN Regulation. GRSP agreed to resume consideration of this issue at its December 2014 session and requested the secretariat to distribute GRSP-55-30-Rev.1 with an official symbol.

GRSP-55-30/Rev.1 | Proposal to modify the text of UN Regulation No. 17 Proposal by the secretariat to correct a reference to UN R25 to refer to the 04 series of amendments rather than to the 03 series of amendments.

21. No new information was provided for this agenda item.

22. The expert from OICA introduced GRSP-55-11 updating his original proposal ECE/TRANS/WP.29/GRSP/2014/3, aimed at removing contradictory provisions for components to be simultaneously type approved to more than one UN Regulation. GRSP adopted ECE/TRANS/WP.29/GRSP/2014/3 as amended by Annex III to the GRSP 55th session report. The secretariat was requested to submit ECE/TRANS/WP.29/GRSP/2014/3 to WP.29 and AC.1, for consideration and vote at their November 2014 sessions as draft Supplement 1 to the 04 series of amendments to the UN Regulation.

GRSP-55-11 | Proposal to correct the draft Supplement 1 to the 04 series of amendments to UN Regulation No. 25 Correction to include provisions for the exemption of certain headrests of M₂ and M₃ vehicles approved according to UN R80.

GRSP/2014/3 | Proposal for Supplement 1 to th e 04 series of amendments to Regulation No. 25 UN R17, R25 and R80 address head restraints for various categories of vehicles. In order to prevent redundant application of these regulations, this amendment clarifies that head restraints approved under UN R17 would be exempted from the requirements of UN R25 and that UN R25 does not apply to coach and bus seats approved under UN R80.

23. The expert from the Russian Federation introduced ECE/TRANS/WP.29/GRSP/2014/4, proposing that during a pendulum impact test the cab should remain attached to the chassis frame at no fewer than three points. The expert from Sweden argued that the current text of the Regulation was enough to guarantee the aimed level of safety.

GRSP/2014/4 | Proposal for Supplement 3 to the 03 series of amendments to Regulation No. 29 Proposal to require that the vehicle cab remain attached to the vehicle frame by at least three mounting points following the pendulum test.

24. GRSP considered and adopted GRSP-55-01-Rev.1, GRSP-55-02 and GRSP-55-33, as reproduced in Annex IV to the GRS 55th session report, updating provisions of UN Regulation No. 44. The secretariat was requested to submit the three proposals combined, to WP.29 and AC.1, for consideration and vote at their November 2014 sessions as draft Supplement 9 to the 04 series of amendments to the UN Regulation.

GRSP-55-01/Rev.1 | Proposal for Supplement 8 to the 04 series of amendments to Regulation No. 44 Updated proposal to clarify various technical provisions as developed by the Technical Services Group (TSG) on Regulation No. 44.

GRSP-55-02 | Proposal for Supplement 8 to the 04 series of amendments to Regulation No. 44 The present requirement for booster with belt guides for the diagonal belt is more stringent than for boosters without belt guides. This proposal aligns the requirement for belt disengagement with the requirements for other child restraint systems ((e.g. the displacement criteria and the criteria as indicated in Annex 15, para. 6.2.4.) and at the same time proposes new language to clarify the affected text.

GRSP-55-33 | Proposal for Supplement 8 to the 04 series of amendments to Regulation No. 44 Proposal to align UN R44 with UN R129 with respect to the references to European standard EN 71:2009 (which specifies safety requirements for toys, especially with regard to chemical composition, flammability, and other mechanical and physical properties).

25. The expert from France gave a presentation (GRSP-55-39) to inform GRSP about the outcome of tests made on Child Restraint Systems (CRS), equipped with a shield cushion instead of harnesses to subdue the movement of children during collisions. He added that these tests showed that the shield system did not restrain the children in the geometry of the CRS, thus, compromising their full protection. The expert from Japan informed GRSP that some experimental data were available on the kinds of CRS in his country. The expert from Germany, on behalf of the European Enhanced-safety Vehicle Committee (EEVC), announced the intention of his organization to carry out further tests aimed at proposing amendments to the UN Regulation and reduce the risks by using these CRS. He added that every manufacturer producing CRS with a shield system should take note of the potential risk of ejection under specific circumstances and should investigate the safety level accordingly. Following the request of the expert from France, GRSP agreed to resume consideration of this issue by an exchange of information at its December 2014 session.

GRSP-55-39 | Child Restraint Systems: A Study on Shield Systems Presentation on the promising results of research into the use of shield systems to secure children in child seats.

26. The expert from France, Chair of the frontal impact (FI) IWG, introduced a proposal of amendment to update the UN Regulation (GRSP-55-21-Rev.1 superseding ECE/TRANS/WP.29/GRSP/2014/6) in view of the new draft UN Regulation (full-width frontal collision) on improving the protection of older occupants. GRSP agreed to resume consideration of this agenda item at its December 2014 session and requested the secretariat to distribute GRSP-55-21-Rev.1 with an official symbol.

GRSP-55-21/Rev.1 | Proposal for 03 series of amendments to Regulation No. 94 Proposal as revised during the 55th GRSP session (superseding document GRSP/2014/06) incorporating changes to UN R94 in light of the development of the new regulation concerning protection in frontal collisions with focus on the restraint system, especially to improve the protection of older occupants.

GRSP/2014/6 | Proposal for the 03 series of amendments to Regulation No. 94 In parallel with the introduction of a new Regulation on a frontal impact with focus on the restraint system, this proposal would limit the chest deflection of the Hybrid III dummy to 42 mm (from the current 50 mm) in order to promote improved protection of older occupants.

27. GRSP resumed consideration on the remaining issues of the proposed 01 series of amendments to UN Regulation No. 127 (ECE/TRANS/WP.29/2014/38), such as the tolerances of the flexible pedestrian legform impactor (FlexPLI). GRSP finally adopted GRSP-55-14-Rev.3 (incorporating GRSP-55-24), as reproduced in Annex V to this report. GRSP requested the secretariat to send the proposal (WP.29-163-06) to WP.29 and AC.1 for consideration and vote at their June 2014 sessions as a draft amendment to ECE/TRANS/WP.29/2014/38. GRSP also adopted GRSP-55-44, as reproduced in Annex V to this report, to introduce a parallel correction to Supplement 1 of the original version of the UN Regulation (ECE/TRANS/WP.29/2014/37). GRSP requested the secretariat to send the proposal (WP.29-163-07) to WP.29 and AC.1 for consideration and vote at their June 2014 sessions as a draft amendment to ECE/TRANS/WP.29/2014/37.

28. GRSP agreed to resume consideration at its December 2014 session of this agenda item based on a possible proposal of an Addendum to the M.R.1 to incorporate the FlexPLI.

GRSP-55-14/Rev.3 | Proposal to amend the draft 01 series of amendments to Regulation No. 127 Corrections to draft text and revision of entry into force dates to occur on 1 September following IWVTA recommendations. This revised document also incorporates the Korean proposal to amend GTR No. 9 (document GRSP-55-24) and OICA proposal on Annex 5 (document GRSP-55-44).

GRSP-55-24 | Proposal of amendment to documents GRSP/2014/2 and GRSP/2014/5 Proposal to clarify figure 11 in the draft amendments to GTR No. 9 by substituting the description "Figure 11: Example of marking of HIC 1000 zone and HIC 1700 zone".

GRSP-55-44 | Proposal to amend Supplement 1 to Regulation No. 127 Proposal to remove the specification of "±0.01 m/sec" for the accuracy of the velocity measurement in Annex 5, Paragraph 3.2.1. This would leave in place the specification to use the measurement procedure if ISO 3784:1976 which specifies an accuracy of ±1 %.

WP.29-163-07 | Proposal for amendments to the draft Supplement 1 to the original version of UN Regulation No. 127

WP.29/2014/37 | Proposal for Supplement 1 to Regulation No. 127 Modifications primarily to the headform test procedures in accordance with the proposed amendment 2 to GTR No. 9 as amended and adopted by the GRSP as its 54th session (document GRSP-54-09/Rev.1 as amended and reproduced in Annex V to the GRSP session report. The proposal addresses the adult headform test area and bumper test area.

WP.29/2014/38 | Proposal for the 01 series of amendments to Regulation No. 127 Draft 01 series of amendments to Regulation No. 127 presented in a consolidated text of the regulation as adopted by GRSP and which aligns the test requirements of UN Regulation No. 127 with UN GTR No. 9 Phase 2 (Flex-PLI), incorporating Supplement 1 to the original version of the UN Regulation (determination of the headform test points). This proposal was adopted by the GRSP at its 54th session based on document GRSP-54-15-Rev. 1 as reproduced in Addendum 1 (document GRSP/54/Add.1) to the session report.

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.

GRSP-55-08 | Updated proposal of amendments to the draft 01 series of amendment to Regulation No. 129 Updated version of the proposed 01 series of amendments to UN R129 prepared by the Informal Group on Child Restraint Systems. The amendments propose to extend the scope of the regulation to cover non-Integral child restraint systems ("Universal Booster" or "Specific to vehicle Booster") (Phase 2 of the UN Regulation).

GRSP-55-34/Rev.1 | UN Regulation No. 129 current and future development Presentation on the development of the regulation on enhanced child restraint systems, including review of the current phase 2 on booster and related seats and plans for phase 3 on stand-alone belted integral CRS.

GRSP-55-35 | Child safety with respect to vehicle protection and booster seats - a proposal for a CRF for children > 4yo Presentation on child restraint fixtures (CRF) and their relationship with in-vehicle safety systems, arguing that children benefit from certain CRF configurations that position the occupant for optimal benefit of seat belts or for eventual interaction with a side/curtain airbag.

GRSP/2014/7 | Draft 01 series of amendment to Regulation No. 129 Amendment to introduce all the modifications needed in UN Regulation No. 129 (Enhanced Child Restraint System (ECRS)) that were suggested by the experts of the informal working group on Child Restraint Systems (IWG CRS) to extend the scope of this Regulation to Non-Integral child restraint systems ("Universal Booster" or "Specific to vehicle Booster") (Phase 2 of the UN Regulation).

30. Finally, GRSP considered GRSP-55-37 and GRSP-55-38 tabled by the expert from CLEPA, as a basis for a draft brochure, in the framework of a coordinated information campaign on UN Regulation No. 129. GRSP requested its experts to provide a final text for the December 2014 session of GRSP.

GRSP-55-37 | i-Size Pillars (principles supporting new CRS requirements) Presentation on the main principles behind the new enhanced child restraint systems provisions:<ol><li>Modern dummy and criteria</li><li>Classification based upon child size</li><li>Integral universal ISOFIX</li><li>Side-impact protection</li><li>Mandatory rear-facing up to 15 months</li><li>improved compatibility</li></ol>

GRSP-55-38 | Q&A on i-size child restraint systems Presentation of a question and answer information sheet on the introduction of UN Regulation No. 129.

31. The expert from OICA introduced the last draft UN Regulation on hydrogen and fuel cell vehicles (HFCV) (ECE/TRANS/WP.29/GRSP/2014/8) prepared with the expert of EC and transposing UN GTR No. 13 (HFCV) into the 1958 Agreement. The expert from the Republic of Korea introduced GRSP-55-23, proposing the deletion of any reference to liquefied hydrogen that is not yet covered by the draft UN Regulation. The expert from OICA argued that UN GTR No. 13 also mentioned liquefied hydrogen technology, and that it could be kept as an optional basis for further development. However, he agreed to bring the technology back to the UN Regulation at a later stage when it was ready for regulation.

32. Moreover, the expert from Japan reminded GRSP that his country already legislated Hydrogen Fuelled Vehicles and requested further guidance. GRSP experts noted that Contracting Parties may continue to apply requirements that were in force at the time of accession to this UN Regulation on aspects not currently regulated by the UN Regulation: (i) the electrical safety of electric power train, (ii) the material compatibility and hydrogen embrittlement of the vehicle fuel system and (iii) the post-crash fuel system integrity in the event of full width frontal impact and rear impact. However, the expert from the Netherlands expressed concerns because UN Regulations Nos. 12, 94 and 95 were addressed in the draft UN Regulation to verify post-crash fuel tank integrity. Inversely, he noted that in UN Regulations Nos. 67 (Liquefied Petroleum Gas vehicles) and 110 (Compressed Natural Gases vehicles), reference was not made to such post-crash UN Regulations. Accordingly, it was agreed to insert a footnote in the draft UN Regulation to specify those aspects not yet regulated as a reminder for future development of the UN Regulation and seek further harmonization (GRSP-55-28-Rev.2). However, GRSP agreed to seek guidance from the Administrative Committee for the Coordination of Work (WP.29/AC.2) at its June 2014 session as the issue raised by the expert from Japan would affect a number of UN Regulations.

33. Finally, GRSP adopted ECE/TRANS/WP.29/GRSP/2014/8, as amended by Annex VI to the GRSP 55th session report. The secretariat was requested to submit ECE/TRANS/WP.29/GRSP/2014/8 to WP.29 and AC.1, for consideration and vote at their November 2014 sessions, as draft UN Regulation on hydrogen and fuel cell vehicles.

GRSP-55-23 | Proposal of amendment to document GRSP/2014/8 Proposal to replace references to "hydrogen fuelled" with "hydrogen fuel cell" in order to exclude application to liquefied hydrogen storage systems.

GRSP-55-28/Rev.2 | Draft Regulation on hydrogen and fuel cell vehicles Draft text for the transposition of GTR No. 13 on hydrogen and fuel-cell vehicle safety into a new UN Regulation under the 1958 Agreement. This version incorporates comments received by GRSP at its 55th session and informal document GRSP-55-23 from the expert of Rep. of Korea.

GRSP/2014/8 | Draft Regulation on hydrogen and fuel cell vehicles Draft text for the transposition of GTR No. 13 on hydrogen and fuel-cell vehicle safety into a new UN Regulation under the 1958 Agreement. Part 1 of Annex 1 uses the numbering system prepared for the corresponding annexes of the International Whole Vehicle Type Approval (IWVTA) regulation (UN R0) currently under development.

34. The expert from Australia summarized (GRSP-55-16) the work of transposing UN GTR No. 14 (Pole Side Impact) into a draft new UN Regulation (ECE/TRANS/WP.29/GRSP/2014/9). The experts from the Netherlands and France questioned the inclusion of N1 category of vehicles into the UN Regulation since it was not justified by national data. The expert from the United Kingdom supported this conclusion. The expert from EU informed GRSP that a cost benefit analysis by his organization would better identify the category of vehicles to be addressed. GRSP noted that the specifications of the three-dimensional H-point machine (3-D H machine) of the draft UN Regulation differed from those of the 3-D H machine of the Consolidated Resolution No. 3 (R.E.3). The expert from France, supported by the expert from Italy, questioned the reference to the ISO standard, concerning drawings and dummy specifications instead of a reference to an addendum to the M.R.l. Following the suggestion of the expert from the Netherlands, GRSP also noted that a possible development of the UN Regulation (in parallel to the future Phase 2 of the UN GTR No. 14) could be to include the viscous criteria (VC) and the thorax deflection limit. Moreover, GRSP considered GRSP-55-45 incorporating the amendments to ECE/TRANS/WP.29/GRSP/2014/9 agreed during the session.

35. GRSP adopted ECE/TRANS/WP.29/GRSP/2014/9, as amended by Annex VII to this report and ECE/TRANS/WP.29/GRSP/2014/12, not amended, this last introducing a vehicle-to-pole impact speed of 32 ± 1 km/h regardless to the vehicle width. The secretariat was requested to submit ECE/TRANS/WP.29/GRSP/2014/9 as draft UN Regulation on Pole Side Impact and ECE/TRANS/WP.29/GRSP/2014/12 as draft 01 series of amendments to the UN Regulation to WP.29 and AC.1 for consideration and vote at their November 2014 sessions. However, GRSP requested the expert from Australia to send the proposals to WP.29 at its June 2014 session on a preliminary basis and to seek guidance from WP.29/AC.2 on: (i) Reference to ISO STD (WorldSID) instead of an Addendum to M.R.1. and (ii) transitional provisions of the 01 series of amendments simultaneously adopted with the original version of the UN Regulation.

36. Finally, GRSP agreed to seek consent from WP.29 and AC.3 at their June 2014 sessions on mandating an IWG to harmonize the 3-D H point machine specifications.

GRSP-55-16 | Summary of the transposition of GTR No. 14 (Pole Side Impact) into a draft new UN Regulation Explanation of the steps taken to transpose the provisions of GTR No. 14 into a type-approval UN Regulation on pole side-impact protection, including discussion of the scope, impact side, treatment of hydrogen vehicles, and proposal for a 01 series of amendments that would entail a 26 km/h impact speed for narrow vehicles initially before the amendments would bring narrow vehicles into line with other vehicles at 32 km/h.

GRSP-55-45 | Draft new UN Regulation concerning the approval of vehicles with regard to their pole side impact performance Proposal for a new UN Regulation transposing the requirements of the UN Global Technical Regulation on pole side impact (GTR No. 14). This proposal is accompanied by a proposal for a 01 series of amendments (documentGRSP/2014/12) that would enable Contracting Parties applying this Regulation to require a vehicle-to-pole impact speed of 32 ± 1 km/h regardless of the "vehicle width". This proposal supersedes the earlier version presented in document GRSP/2014/9.

GRSP/2014/12 | Draft 01 series of amendments to the draft new regulation concerning the approval of vehicles with regard to pole side impact performance Proposal for a 01 series of amendments to the proposed new UN Regulation on the approval of vehicles with regard to their pole side impact performance to enable Contracting Parties applying this new regulation to require a vehicle-to-pole impact speed of 32 ±1 km/h regardless of the "vehicle width".

GRSP/2014/9 | Draft new regulation concerning the approval of vehicles with regard to pole side impact performance Draft text transposing GTR No. 14 on pole side impact protection into a UN Regulation under the 1958 Agreement. A proposal for the 01 series of amendments (document GRSP/2014/12) has also been prepared to enable the Contracting Parties applying this Regulation to require a vehicle-to-pole impact speed of 32 ±1 km/h regardless of the "vehicle width".

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.

GRSP/2014/10 | Draft new Regulation on the protection of the occupants in the event of a frontal collision with a focus on the restraint system Text prepared by the Informal Working Group on Frontal Impact (IWG FI) as an outcome of discussions of the Working Party on Passive Safety (GRSP) at its fifty-fourth session (ECE/TRANS/WP29/GRSP/54, para. 23) on developing a separate new Regulation on frontal impact focusing on requirements for restraint systems. .

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.

40. The expert from Turkey informed GRSP about the next inauguration of a National Centre for Passive Safety.

41. GRSP agreed to resume consideration of this agenda item at its December 2014 session on the basis of an updated provisional list of acronyms (GRSP-51-03) to include those of UN Regulation No. 129, from the expert of France.

42. GRSP noted that the consideration of draft Revision 3 to the 1958 Agreement (ECE/TRANS/WP.29/2014/53) was scheduled for the June session of WP.29 as well as other pending issues such as: (i) proxy vote, (ii) the final list A of draft UN Regulation No. 0 and (iii) common commencement dates for new series of amendments to UN Regulations. GRSP noted WP.29-162-18 introducing principles for supplements, series of amendments and Revisions to UN Regulations. GRSP finally agreed to move UN Regulation No. 16 to the final list A, while UN Regulation No. 14 should be moved to list B.

43. Moreover, GRSP noted GRSP-55-17, indicating possible scenarios for the introduction of different propulsion tractions into the UN Regulation in view of IWVTA. The expert from OICA stated that UN Regulations should be considered technologically and fuel neutral. The expert from Germany indicated that the solution of developing specialized Annexes, each dedicated to specific fuel systems, could facilitate Contracting Parties when applying preceding series of amendments. However, he suggested that GRSP-55-17 would be further discussed and referred to the IWG on IWVTA to verify if such a solution would be viable for all UN Regulations. He also envisaged that the issue of cross referencing to other UN Regulations should be further developed by the IWG. GRSP agreed to resume discussion on this issue and to refer in the meantime GRSP-55-17 to the IWVTA IWG for consideration.

GRSP-55-17 | Electric, hybrid vehicles & HFCV – principles for their introduction into UN Regulations in view of IWVTA Presentation by the secretariat to open discussion of issues related to the introduction of provisions for electrified vehicles and systems within the context of the International Whole Vehicle Type Approval (which allows Contracting Parties to grant approvals under earlier series of amendments).

44. The Secretary reported on the highlights of the 162nd session of WP.29 (ECE/TRANS/WP.29/1108).

45. GRSP noted GRSP-55-03, showing a number of inconsistencies between some of the definitions used in UN Regulations from the “UN Vehicle Regulations Dictionary”, as prepared by a former intern of the UNECE secretariat. GRSP agreed to resume consideration of this agenda item at its December 2014 session.

GRSP-55-03 | Compilation of non-harmonized technical terms related to passive safety systems Across its various groups, WP.29 has been looking at the definitions of technical terms used in its regulations from the standpoint of consistency. The GRSP secretariat has compiled terms and definitions found in the regulations under its purview that differ across regulations (including those under regulations managed by other GR). This document is proposed for consideration as a possible starting point for the development of a "dictionary" of harmonized terms and definitions.

46. The expert from the Netherlands introduced GRSP-55-04 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 Germany raised a study reservation on the proposal. Finally, GRSP agreed to resume consideration of this agenda item at its December 2014 session of the basis of a revised proposal prepared by the expert from the Netherlands and to keep GRSP-55-04 on the agenda for reference.

GRSP-55-04 | Proposal for collective amendments to Regulations Nos. 14 and 16 Proposal to clarify that the recently increased height requirements for the effective upper belt anchorage (Supplement 4 to the 07 series of amendments to UN Regulation No. 14) can be satisfied by means of a "belt adjustment device for height" that is part of the belt-anchorage as well as a device that is part of the belt itself, each with a distinctive approach. The proposals are presented as draft Supplement 7 to the 07 series of amendments to Regulation No. 14 and draft Supplement 6 to the 06 series of amendments to Regulation No. 16.

47. GRSP agreed to defer consideration of this agenda item to its December 2014 session due to lack of time and requested the secretariat to distribute GRSP-55-06 with an official symbol.

GRSP-55-06 | Proposal for Supplement 5 to the 03 series of amendments to Regulation No. 95 Proposal by the GRSP secretariat to delete Appendix 3 (examination of the mobile impact barrier) to Annex 5 of UN R95. The secretariat suspects that the appendix is superfluous, but wishes to confirm if Appendix 3 should remain for any examination purposes of the Type Approval Authority responsible for the mobile deformable barrier.

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.

GRSP-55-12 | Proposal for Supplement 2 to the 02 series of amendments to UN Regulation No. 100 Proposal to clarify the requirements of UN R100 specified under paragraph 5.1.1. This paragraph describes the general requirements for the protection of all high voltage parts, including the obligation that such protection against live parts cannot be opened without the use of tools. If connectors can be opened without use of tools or if they do not satisfy the IPXXD/IPXXB protection limits, the provisions of 5.1.1.3 have to be met.

GRSP-55-13 | Proposal for Supplement 4 to the 01 series of amendments to Regulation No. 100 Proposal to clarify the requirements of UN R100 specified under paragraph 5.1.1. This paragraph describes the general requirements for the protection of all high voltage parts, including the obligation that such protection against live parts cannot be opened without the use of tools. If connectors can be opened without use of tools or if they do not satisfy the IPXXD/IPXXB protection limits, the provisions of 5.1.1.3 have to be met.

49. The expert from Germany introduced GRSP-55-18 to clarify provisions for the banned installation of side-facing seats. GRSP agreed to resume discussion at its December 2014 session and requested the secretariat to distribute GRSP-55-18 with an official symbol.

GRSP-55-18 | Proposal to amend UN Regulation No. 80 Proposal to amend the scope and clarify the transitional provisions to avoid misinterpretations for the installation of side-facing seats in category M₃vehicles. The proposal exempts vehicles exceeding 10 tonnes from the prohibition on side-facing seat provided the seat meet conditions specified in the 03 series of amendments to the Regulation.

50. The expert from Japan presented a survey (GRSP-55-26-Rev.1) on the safety of four-wheeled vehicle whose unladen mass was not more than 400 kg, (category L6 and L7); these were shown to be very similar to passenger vehicles (M1) identified in Japan as “New Mobility Vehicles”. He added that these vehicles might be in conformity with a number of safety requirements (i.e. full width frontal collision, UN Regulation No. 95) currently required for passenger vehicles in Japan. He concluded that his country aimed at achieving regulatory harmonization of these vehicles and sought information and comments from Contracting Parties. The expert from EC informed GRSP that his organization was conducting similar safety investigations on L7 vehicles and offered to cooperate with the expert from Japan, and exchange data on cost benefit analysis. GRSP agreed to continue sharing information on this issue at its December 2014 session.

GRSP-55-26/Rev.1 | Survey on Safety of New Mobility Vehicles Presentation on Japan's evaluation of the use of three- or four-wheeled “New Mobility Vehicles” with a passenger capacity of 2 persons and smaller than M1 category as a way to diversify transportation means and offer environmental countermeasures.

51. GRSP noted GRSP-55-27, or the possible insertion of new categories of vehicles (e.g. agricultural trailers and towed machinery) into the Consolidated Resolution on the Construction of Vehicles (R.E.3). It was noted that the proposal had been designed by the Working Party on Lighting and Light-Signalling (GRE) in updating UN Regulation No. 86 (Installation of lighting and light-signalling devices for agricultural tractors) and that GRE agreed to circulate the proposal to all Working Parties for comments. GRSP invited its experts to provide comments on the proposal to the secretariat, before the October 2014 session of GRE.

GRSP-55-27 | Proposal for amendments to the Consolidated Resolution on the Construction of Vehicles (R.E.3) Proposal to add classifications covering agricultural trailers and towed agricultural machinery in the Consolidated Resolution on the Construction of Vehicles (R.E.3) transmitted from GRSG to GRSP for input.
