Proposal to remove the prohibition on use the Unique Identifier per the WP.29 decision to change the default application of the UI from a requirement (requiring prohibition in cases where UI does not apply) to a permission (requiring an affirmative statement that UI may be used under a Regulation).

Introduces an explanation to the background of the procedures to test
vehicle types including DPPS

Information to serve as guidance for Technical Services and Type Approval Authorities

Proposed modifications to ECE/TRANS/WP.29/GRSP/2025/7

Proposal to allow the use of talcum for the dust resistance test as an alternative to dry quartz

Proposal ro clarify that the removal of an insert may also trigger additional tests with alternative dummy statures.

Proposal to improve the shoulder height requirements to properly take the dimensions of premature newborns into account

Presentation on creation of ISOFIX. There is interest from several specialists on Child Restraint Safety, CRS manufacturers and Consumer Organisations to add a 3rd fixed point.

Question remains, what if the ECRS is permanently or temporarily connected, on what basis can compliance with (the technical provisions of) UN R10 be required ?

Proposal applies to Supplements 3 to the 04 series of amendments. Proposal to clarify the scope of data from tests to the windscreen that must be provided for the purpose of type approval.

Procedural request for authorisation to introduce provisions for supply lines between compressed hydrogen storage systems (CHSS) and their thermally activated pressure relief devices (TPRD) based on the outcomes from the transposition of GTR-Phase 2 (Amendment 1) transposition into UN R134.

Proposal to amend UN R134 regarding hydrogen and fuel cell vehicles. The amendment clarifies requirements for supply lines serving additional thermally activated pressure relief devices (TPRDs) on compressed hydrogen storage systems. It specifies that supply lines must be constructed from metallic materials, demonstrate mechanical integrity through qualification tests excluding drop tests, and establishes handling procedures to prevent damage. The proposal also defines container attachments and refines test procedures for burst pressure, drop impact, permeation, and localized leak testing.

The task force works on the improvement of UN Regulation no. 134 and a potential new UN Regulation on liquefied hydrogen

Proposal to update the captions underneath multiple ISO envelope
drawings in appendix 2 to annex 6, including adding references to UN Regulation No. 129.

Proposal to introduce provisions on thermal propagation as a result of a single cell thermal runaway.

Proposal to change the transitional provisions in such a way as to allow Contracting Parties to issue approvals according to the 05 series of amendments.

Proposal to amend UN R129 concerning Enhanced Child Restraint Systems. Modifications include: adjusting shoulder height dimensions in Annex 18 table 1 to align with anthropometric data for children from 40-70 cm; permitting one additional insert layer for infants below 50 cm; establishing minimum stature of 35 cm; and adding transitional provisions regarding type-approval acceptance timelines from September 2028-2029. Changes address fit concerns for premature newborns and small children.

Proposal to allow the use of talcum for the dust resistance test as an alternative to dry
quartz.

Proposal to enable approval of an Enhanced Child Restraint System (ECRS) with a module that is, or can be, converted into a booster seat or an ECRS with a module of a vehicle-specific application.

Proposal to update the options under multiple International Organization for Standardization (ISO) envelope drawings in appendix 2 to annex 6, including adding references to UN R129.

Proposal to correct paragraph references and add the Regulation number in the introduction section (i.e., replace “Regulation No. XXX” with “Regulation No. 174”).

Proposal to clarify the scope of data from tests to the windscreen that must be provided for the purpose of type approval.

Proposal to clarify the scope of data from tests to the windscreen that must be provided for the purpose of type approval.

Proposal to introduce provisions on Deployable Pedestrian Protection Systems (DPPS) pursuant to Amendment 3 to GTR 9.

Proposal to clarify that the removal of an insert may also trigger additional tests with alternative dummy statures.

Proposal to improve the shoulder height requirements to properly take the dimensions of premature newborns into account.

Proposal to ensure that vehicles exhibiting functionality meeting the definition of ACSF-B2 or -E are required to comply with the 01 series of R171 (or later). The 01 series added the necessary technical requirements to ensure the safety of features that allow ‘hands-free’ operation or perform system-initiated manoeuvres.

Pursuant to changing the application of the Unique Identifier (UI) under the 1958 Agreement, this proposal deletes the prohibition on use of the UI for replacement brake components under UN R90. Originally, the UI was applied by default to all UN Regulations which therefore required certain regulations to prohibit its use. Pursuant to the adopted proposal WP.29/2025/17, each regulation grants permission to use the UI so the provision prohibiting use under UN R90 is no longer needed.

Request for authorization to develop test procedures to assess the mechanical integrity and durability of supply lines to any additional Thermally activated Pressure Relief Devices (TPRD) connected directly to the Compressed Hydrogen Storage System (CHSS).
