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.

Japan proposes changes to the draft text (document GRSP/2013/22) intended to transpose GTR No. 13 on hydrogen fuel-cell vehicle safety into the UN Regulation type approval system.

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.

The United States will not support the proposed amendment in its current form. The amendment would increase headrest heights for front outboard seating positions from 800 mm to at least 830 mm while allowing a decrease in minimum heights to 720 mm from 750mm. In addition, the amendment would allow decreased rear heights. The US believes the amendment lacks adequate evidence-based justifications for the proposed changes.

EC proposals to revise GTR No. 13 based upon items identified during the process of transposing the GTR into the form of a UN Regulation force use in type-approval systems.

Corrections and clarifications to the proposed amendment to the enhanced child restraint systems regulation.

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.

Presentation on Japanese research into
dummy responses and chest injury measures for different seat-belt paths under the full-width rigid barrier and sled tests. Since the seat-belt path influences chest deflection results, Japan proposes that UN R94 include seat-belt path definition.

Draft amendment to UN R94 as prepared by the WP.29 expert group on frontal impact to introduce provisions for offset deformable and full width rigid barrier tests. This draft is presented only for informational purposes pending submission of a final version for consideration at the May 2014 GRSP session.

Update on changes to the CONFOR foam flesh used in the EEVC lower and upper legform impactors.

Presentation of US concerns regarding proposed definitions for locating the point of measurement (i.e. measuring point, target point, and first contact point definitions) within the test zone, changes to the test zone boundaries to clarify the adult and child Head Injury Criterion (HIC) zones, and to amend the leg form test procedure to align the leg form center plane with its measuring point.

[Note: the reference to document GRSP/2011/12 does not appear to correspond with the content of the US statement. Rather, the remarks align more closely with document GRSP-54-07/Rev.1 proposing changes to the draft amendment as presented in document GRSP/2013/25).]

Statement of US concerns with the draft amendment to introduce the Flex PLI test tool into GTR No. 9 (document GRSP/2013/25) in particular with regard to the use of the injury assessment reference values (IARVs). US definition of the IARV will be dependent upon the outcome of a US cost-benefit analysis based upon the characteristics of the American vehicle population. The US cannot accept injury curves that do not fall within what is justifiable according to US traffic conditions.

The draft amendment to introduce the Flex PLI test tool as updated in the informal working group meeting of 16 – 17 December 2013.

Reiteration of Japanese concerns over the classification of quadricycles which can be classified as mini-vehicles (keijidosha) under Japanese legislation while being classified under UN Regulations as motorcycle derivatives (i.e., L category vehicles). As a result, certain L vehicles are subject to separate crashworthiness requirements, suggesting that they should be addressed under a separate regulation from motorcycle/moped requirements.
