UN R10 revision proposes to replace Pulse 4 with starting profile, to amend para. 6.9.1 to align with ISO 16750-2:2023 wording, and to clarify immunity to transient disturbances testing methods and functional status classifications. The revision specifies test levels, pulse durations, and functional status requirements for ESA in 12 V and 24 V systems according to ISO 7637-2:2004 and ISO 7637-2:2011, with transition provisions from UN-R10.07 to Supplement 2.
During IWG-EMC 53rd meeting, Dutch delegation referenced the 2018 Stint accident in proposals to extend UN R10 radiated emissions below 30 MHz and immunity below 20 MHz requirements. Official forensic investigation reports by TNO and Dutch Safety Board ruled out electromagnetic compatibility as a causal factor. The Stint’s drive system was fully immune under UN R10 Annex 6 at 40 V/m. Level-crossing infrastructure fully complied with EN 50121 railway EMC standards. True root causes were mechanical, electrical, and homologation failures including braking deficiencies, electrical throttle flaw, and vehicle instability. OICA recommends rejecting any expansion of UN R10 scope based on this incident.
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.
