Proposal to improve efficiency of test methods by adding a reference to SAE J1349 or applicable local regulations, in addition to UN R85 and ISO 1585, to para. 6.1.2. and para. 6.1.2.1., and delete the requirement for Current integration measurement from para. 5.2.1. The additions provide consistency throughout the regulation and clarify that test results obtained in accordance with applicable local regulations are considered valid. The deletion removes an inconsistency whereby only Current integration measurement specifies a frequency of 20 Hz, while other items specify at least 10 Hz, and eliminates inapplicable wording carried over from UN R154.
Proposal to:
Japan proposes to add a specific requirement for vehicle speed measurement frequency of 20 Hz in Table A3/1 of Annex 3, consistent with UN R154; revise para. 2.4 to clarify that both constant and transient cycles test methods are permitted; delete redundant text from para. 2.4.1 regarding test cycle requirements; and delete from para. 5.1 the requirement that resolution and method for SOCE availability be determined in agreement with authorities, as these are already specified.
The agenda includes a roadmap for the 08 series of amendments with proposals from contracting parties and non-governmental organisations, discussion of numerous technical documents covering harmonics, flicker requirements, charging conditions, immunity testing, radiated emissions, and blind spot detection systems. Referenced documents include EMC-52-05, EMC-53-05, EMC-53-10, EMC-53-11/Rev.1 from previous sessions. Subsequent meetings are scheduled online from December 2026 through July 2027, with a face-to-face meeting proposed in November 2027.
Revised proposal for the amendment of UN R13 with regard to automatic coupling devices as a result of the discussions held during the 11th ACV informal group session.
