Japan argues to limit the scope (as in the GTR) to passenger vehicles with a GVM of 4,536 kg or less; defer liquefied hydrogen storage system (LHSS) provisions; specify frontal impact and rear impact tests (or allow national tests until phase 2 of GTR 13 is complete),and add batch and production test requirements. Japan also notes editorial corrections.

Japanese statement proposing to remove vehicle categories L5-L7 (three-wheelers and quadricycles) from the proposals to regulate “rechargeable energy storage systems” (REESS) in mopeds, motorcycles, and similar vehicles as a condition for its acceptance either of a new regulation or as an amendment to UN R100 on electric-powered vehicles.

Japan is developing national legislation to prescribe requirements for the body, hydrogen storage containers and their specific components, batteries etc. of hydrogen fuel-cell powered motorcycles.

Proposal from Japan to outline a 01 series of amendments to the draft new UN Regulation with regard to the Full Width Rigid Barrier test. This proposal would enable Contracting Parties to apply this Regulation with a Thorax Compression Criterion (ThCC) of 34 mm for the Hybrid III 5th female dummy on the passenger seat in the event that both the 00 series draft new regulation and the 01 series amendments are adopted concurrently.

Proposal to include “MFP” in the labeling requirement for hydrogen containers. MFP refers to the maximum allowable container pressure under normal use.

Proposal to require seat-belt reminders for all seating positions, including rear positions, and to clarify the scope of the regulation.

Companion presentation to the proposal contained in document GRSP-57-17.

Proposal of draft text to transpose GTR No. 7 (head restraints) into UN R17, including the draft Amendment 1 to GTR 7 addressing use of the BioRID II test dummy, backset measurement method revision, and new head restraint height thresholds.

Proposal to require seat-belt reminders for all seating positions, including rear positions, and to clarify the scope of the regulation.

Responses to questions regarding seat-belt reminders asked during the last GRSP session (May 2015) based upon various selected studies.

Proposal to change the burn-rate in documents GRSP/2016/3, GRSP/2016/5, and GRSP/2016/6 from [250 mm] to the equivalent of the FMVSS 302 specification, i.e., 100 mm.

Proposal to introduce provisions for seat-belt reminders for all vehicle seating positions pursuant to the outcome of the Task Force on Seat-belt Reminders discussions.

Proposal to clarify the “Minimum requirements for safety-belts and Retractors” table in Annex 16.

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.

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 to delete measurement of the femur bending moments because such measurements are unnecessary under the full width rigid impact test.

Proposal to clarify and correct the reference in paragraph 8.3.6. to UN R14 and the new UN Regulation on ISOFIX anchorages with regard to the measurement of the pitch angle used for the geometrical assessment of the installation of ISOFIX child restraint fixtures. This proposal relates directly to the supplements presented in document WP.29/2017/120.

Proposal to introduce a new measurement procedure for the effective height of the head restraint and introduction of the Biofidelic Rear Impact Device (BioRID). This proposal eliminates the backset measurement test procedure using the HRMD method.

Proposal to align UN R129 with the descriptions used in of UN R44 and UN R94 which refer to resultant head and chest accelerations.

Proposal for editorial corrections to ECE/TRANS/WP.29/GRSP/2019/27

Proposal to to delete paragraph 13.3.4. of ECE/TRANS/WP.29/GRSP/2019/27 as difficulty may arise to judge whether an approval according to the preceding series of amendments is still valid.

Proposal based on document GRSP/2019/19 to define the introduction of limit values for chest vertical acceleration of Q-dummies during dynamic testing of Enhanced Child Restraint Systems (ECRS).

Japan’s position on the alignment of UN R137 with GTR 20 on electric vehicle safety.

Proposal to amend the requirements concerning post-crash electrical safety in the event of frontal collision. The proposal aligns post-crash electrical safety requirements with GTR 20 and aligns administrative provisions with Revision 3 of the 1958 Agreement. The amendments would not affect approvals for vehicles without high-voltage electric power trains.

Proposal to amend the requirements concerning post-crash electrical safety in the event of lateral collision. The proposal aligns post-crash electrical safety requirements with GTR 20 and aligns administrative provisions with Revision 3 of the 1958 Agreement. The amendments would not affect approvals for vehicles without high-voltage electric power trains.

Proposal to transpose the electrical safety requirements of GTR 20 into UN R100 and align administrative provisions with Revision 3 of the 1958 Agreement. The proposal provides for a 2-3 year transitional period. The proposal also integrates the amendments to UN R100 provided in document GRSP/2019/17.
