The proposal also covers a specific provision on optional monitoring of headform contact with A-pillars, windscreen header and cowl and proposes inconsequential adaptations and clarifications to the existing requirements.

Proposal to align UN R135 with the provisions of GTR 20 on post-crash electrical safety and the administrative provisions of Revision 3 to the 1958 Agreement. The proposed amendments only relate to vehicles with an electric power train operating at high voltage.

Proposal from GRSP to clarify assessment of head containment injury criterion.

Proposal from GRSP to clarify requirements for the adjustment of the passenger seat back when installing the Hybrid-III 5th percentile female dummy.

Proposal from GRSP to clarify requirements for the adjustment of the passenger seat back when installing the Hybrid-III 5th percentile female dummy.

Proposal from GRSP to correct the vehicle type definition.

Proposal from GRSP to align UN R12 with the provisions of GTR 20 on post-crash electrical safety and the administrative provisions of Revision 3 to the 1958 Agreement. The amendments only impact the approval of vehicles with an electric power train operating at high voltage.

Proposal from GRSP to update provisions in line with the 03 series of amendments to UN R100, introduce optional requirements to enable the mounting of removable REESS in any orientation in order to enable safe deployment of swappable batteries, and correct the numbering of the explanatory notes to the new definition “specific voltage condition” in paragraph 2.47.

Proposed text to facilitate the administrative control of two-stage requirements introduced in the 03 series of amendment.

Proposal aimed at developing measures/technologies by trailer manufacturers for a reduction of CO2 emissions.

Test prepared by the experts of the Informal Working Group (IWG) on hydrogen and fuel cell vehicles (HFCV), UN Global Technical Regulation No. 13, Phase 2 (GTR13-PH2) and proposes enhancement of the global harmonisation of the technical requirements of compressed hydrogen storage systems and vehicles equipped with them.

The proposal aims to introduce an optional (on the choice of the manufacturer) test procedure for frontal airbags in combination with rearward facing child restraint systems in the rear seat to demonstrate that no deactivation of the airbag is needed. The aim of the proposal is to promote new airbag technologies.

Text to clarify the procedure and the characteristics of the measuring device used for the compliance test for the vehicle exhaust system.

Text to clarify how the assessment of the connection of the Safety-belt reminder system in case of removable seats has to be done.

Proposal to amend document GRSP/2022/4 concerning provisions for Adjustable Ride Height Suspension Systems (ARHSS). This proposal supersedes the previous proposals in documents GRSP-67-07, GRSP-68-18 and GRSP-70-17.

The proposed test makes a few minor adaptations and clarifications to the existing requirements.

Collective amendments to UN R94 (Frontal collision), UN R95 (Lateral collision) and UN R137 (Frontal Impact with focus on restraint systems). Aim of this document is, to clarify, if it was the intention of Informal Document GRSP-66-32 to delete paragraph 7.1.2.1. to 7.1.2.2.2. If it was the intention to delete these paragraphs, do we still need the simplified test described in Annex 7 of the Regulation?
