Proposal to reintroduce a footnote in Annex 4 (Data elements and format) unintentionally omitted during transcription of the original proposal (“Format requirements specified below are minimum requirements and manufacturers can exceed them.”)

Review on the possible direction
(1) new series of amendment
(2)single series structure

• Additional chassis dyno quality criteria
• Threshold pressure calculation method
• Table 5.3
• Annex C clarifications and adaptations

Proposal to introduce optional calculation method for determining f₀ and f₂ road load coefficients, allow measurement of drivetrain delta on component dynamometer, permit evaluation of split runs to increase data base, and enable test vehicle configuration using interpolation method. The calculation method determines final f₀ and f₂ values considering theoretical delta between coast down vehicle and final vehicle. Component dynamometer measurement increases accuracy because not all combinations of road load relevant components can be assembled, allowing all component combinations to be evaluated independently.

Proposal concerning the approval of the wind tunnel facilities.

Proposal to bring clarity in the text relating to On-Board Diagnostics (OBD).

Calibration of measurement equipment to PN10 measures more particles than calibration to PN23. It is therefore logical that compliance with a limit when measured according to PN10 demonstrates compliance with the same limit according to PN23 but this text should be added for legal certainty.

Proposal seeks to remove reference to providing information in the vehicle handbook, so as to maintain current harmonised practices.

Comments on the proposal to delete the 2m width requirement for parking lamps.

Draft proposal to update the references and application of ISO 17268 (Gaseous hydrogen land vehicle refuelling connection devices).

Proposal to improve usability, especially in enabling user targeting of the stopping point of the vehicle.

Proposal to clarify that the use of any braking system control for testing the effectiveness of the secondary braking system in failure conditions is allowed.

Proposal to replace references to UN GTR 21 by its type-approval equivalent UN R177, provide transitional provisions pursuant to amendments introduced in Supplements 10 and 11, and clarify calibration provisions and procedure for system check (cf: ISO 362).

Small Volume Manufacturers (SVMs) are defined as manufacturers producing fewer than 10,000 M1 or 22,000 N1 vehicles annually in the European Union. Ultra Small Volume Manufacturers (USVMs) produce fewer than 1,000 vehicles annually. SVMs receive exemptions from certain systems and testing requirements, including OBM, EEEDWS, and OBFCM installations for M1 and N1 vehicles. Type approvals granted before July 1, 2030 remain valid. In-service conformity checks are not mandatory for SVMs.
