The UN World Forum for Harmonization of Vehicle Regulations (WP.29) enables governments to cooperate internationally in developing vehicle regulations concerning safety, environmental performance, and energy efficiency.
GlobalAutoRegs is a technical resource for members of the regulatory affairs community interested in this international collaboration.
| UN R10: Standardized testing conditions for harmonics and flicker vs. actual grid connection |
| Reference Number: EMC-54-11 |
|
International reference standards for harmonics and flicker testing define differing applicable supply voltage levels and operating frequencies. CLEPA proposes maintaining baseline requirements for UN R10.08 unchanged, testing according to standardized parameters of reference IEC standards. Contracting Parties with diverging local grid configurations should define tailored national requirements or propose harmonized evaluation methods directly within relevant IEC standard committees, as direct application or mathematical conversion of limits for diverging grids lacks standardized metrological foundation in IEC publications. |

| UN R10: Revision of immunity to transient disturbances |
| Reference Number: EMC-54-10 |
|
Document raises question on the use of a combination of Level I/II immunity tests based on ISO 7637-2:2011 in the 07 series given that the 06 series prescribed Level III. |

| UN R10: Position on use of "Stint" event to justify EMC provisions |
| Reference Number: EMC-54-09/Rev.1 |
|
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. |

| Electromagnetic Compatibility: Agenda for the 54th (September 2026) session |
| Reference Number: EMC-54-01/Rev.1 |
|
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. |

| GTR 21: Improvement proposal for phase 4 |
| Reference Number: EVE-99-13 |
|
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. |

| Reference Number: EVE-99-12 |
|
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. |

Minutes from the 27th meeting of GRSP TF on AVRS held Wednesday 1st July 2026 online. The agenda and previous minutes were approved. EC reported from June WP.29-199 TF Expert FADS and presented WP.29-199-19. GRSP TF AVRS must complete crashworthiness regulation for Category Y and Pedestrian Protection R127, GRE TF AVSR ADS marker lamps, GRE IWG EMC refinements for ADS in 10R08, and GRPE TF AVRS amendments to UN Regulation No. 154. Regarding amendment proposals to UN Regulations Nos. 35 (ECE/TRANS/WP.29/2026/104) and 68 (ECE/TRANS/WP.29/2026/146), AC.1 postponed voting to the next session due to required quorum not being attained.
