This informal doc amends the draft supplement presented in document GRSP/2016/24 in order to harmonize the mass tolerances of the ISO fixtures. The proposal deletes a reference to the center of gravity and geometrical centroid. The centroid would need more information before choosing tolerances needed for certification tests.

This informal doc amends the draft supplement presented in document GRSP/2016/21 in order to harmonize the mass tolerances of the ISO fixtures. The proposal deletes a reference to the center of gravity and geometrical centroid. The centroid would need more information before choosing tolerances needed for certification tests.

The current paragraph 15.6 foresees that, for type approval to the 07 series, safety belt reminders are not compulsory until 1 September 2022 on the exempted seats (e.g. seat rows with a suspension seat). In the absence of any clarification for the case of extensions of type approvals, paragraph 15.6 of UN R16.07 could create interpretation problems when a previously granted approval for an exempted vehicle needs to be extended after 1 September 2022. As previously agreed by GRSP, this proposal would clarify that the new SBR requirements would be applicable only for new type approvals as from 1 September 2022, such that previously granted approvals would remain accepted, with their exemption.

Draft text presented by the EVS informal group for GRSP discussion and consideration.

Proposal to resolve divergent interpretations with regard to child restraint systems in UN Regulation No. 44, superseding document GRSP/2016/18.

Proposal to add the Q0 infant test dummy to the UN R44 procedures in response to problems encountered in acquiring the currently specified P0 dummy.

Proposal to apply a minimum burst pressure (BPmin) in place of the current COP that only requires the manufacturer to provide mid-burst pressure with specified variation. The proposal also deletes the phrase “and in no case less than the value necessary to meet the stress ratio requirements” which was erroneously copied into the regulation.

Phase 2 proposes to amend the UN Global Technical Regulation No. 9 on pedestrian safety by introducing the flexible pedestrian legform impactor (FlexPLI) as a single harmonized test tool in order to enhance the level of protection for pedestrian lower legs. NHTSA has expressed concern that the injury assessment reference values (IARVs) for this GTR may not meet the needs for injury mitigation in the U.S. In order to enable the proposed Phase 2 amendment to move forward with US support, the US proposes additions to the GTR preamble to make clear its position and intentions regarding assessment of the IARV and to allow the brackets to be removed from the IARV in the draft amendment.

Announcement of task force establishment, organization, and meeting plans towards developing a proposal for the assessment and approval of deployable exterior pedestrian safety systems (e.g., active bonnet).

Proposal to clarify and make editorial corrections to the text of the 02 series of amendments to the UN Regulation No. 129. This proposal supersedes document GRSP/2016/23 and amends WP.29/2016/107 (02 series of amendments to the UN Regulation) and GRSP/2016/19 (Proposal for Supplement 1 to the 02 series of amendments to Regulation No. 129).

Proposal to clarify and make editorial corrections to the text of the 02 series of amendments to the UN Regulation No. 129. This proposal supersedes document GRSP/2016/22 and amends WP.29/2016/106 (02 series of amendments to the UN Regulation).

Proposal to add references to the steering gear provisions of UN R137 (full width frontal impact) as a compliance alternative in addition to the current references requiring compliance with similar provisions in UN R94 (offset deformable barrier frontal impact).

Proposal to correct figure 2 in Annex 1B to show the referenced zones A and B, to add sentence “Non-rigid material of < 50 Shore A hardness may be removed in order to demonstrate that covered or padded rigid parts are not contacted by the head or the chest of the manikin during the test.”, and to make editorial improvements.

Explanation of the proposals in document GRSP/2016/18 intended to resolve divergent interpretations with regard to child restraint systems in UN Regulation No. 44.

Final report, pursuant to the amendment’s approval by GRSP, to accompany the amendment to align the specifications for back doors with those of side doors with rear mounted hinges as established in UN Regulation No.11.

Draft proposal for eventual submission to WP.29 for the further development of the GTR on hydrogen fuel-cell vehicle safety, including the following additional areas for consideration:

1. Scope revision to address additional vehicle classes;
2. Requirements for material compatibility and hydrogen embrittlement;
3. Requirements for the fuelling receptacle;
4. Evaluation of performance-based test for long-term stress rupture proposed in Phase 1;
5. Consideration of research results reported after completion of Phase 1 – specifically research related to electrical safety, hydrogen storage systems, and post-crash safety;
6. Consideration of 200 per cent NWP or lower as the minimum burst requirement;
7. Safety guard system for the case of isolation resistance breakdown.

Proposal for the Phase 2 development of GTR No. 13, including

1. Further consideration of items in the original authorization (document WP.29/AC.3/17);
2. Potential revision of the scope to address additional vehicle classes;
3. Requirements for material compatibility and hydrogen embrittlement;
4. Requirements for the fueling receptacle;
5. Evaluation of performance-based test for long-term stress rupture proposed in Phase 1 (including assessment of a procedure to evaluate the risk of long-term stress rupture of storage containers made from composite fiber reinforced polymers);
6. Consideration of research results reported after completion of Phase 1 – specifically research related to electrical safety, hydrogen storage systems, and post-crash safety;
7. Consideration of 200 per cent Nominal Working Pressure (NWP) or lower as the minimum burst requirement; and
8. Consider Safety guard system for the case of isolation resistance breakdown.

Review of the discussions and supporting data towards the further development of CRS requirements under UN R129.
