Document presents technical challenges to defining retrofit kit types for electric conversion and approval processes. Identifies that retrofit kit type perimeter depends on the regulation considered, with different requirements across UN R10, R13, R100, R85, R138, WLTP, R79, R39, R51, R89, R121, and R122. Presents testing challenges at vehicle, component, and EPRS levels, noting that testing a kit type not installed on a vehicle is impossible to account for all impacts on the vehicle.

Agenda for the 132nd session of the Working Party on General Safety Provisions, scheduled 28 September to 2 October. The session will address amendments to UN R107, UN R43, UN R46, UN R67, UN R110, UN R116, UN R161, UN R162, UN R163, UN R151, UN R158, UN R159, UN R166, UN R121, UN R122, UN R125, UN R0, UN R160, UN R169, UN R58, UN R105, UN R73, UN R39, and UN R58. The session will also cover vehicle automation, periodical technical inspections, driver distraction and drowsiness warning systems, and door open warning systems.

Proposal to amend UN R18, UN R39, UN R46, UN R55, UN R58, UN R67, UN R73, UN R93, UN R97, UN R102, UN R105, UN R107, UN R110, UN R116, UN R121, UN R122, UN R125, UN R144, UN R147, UN R151, UN R158, UN R159, UN R160, UN R161, UN R162, UN R163, UN R166, UN R169, UN R176, UN R181, UN R182 and UN R183:

• Add new paragraphs defining Software Identification Number by reference to Consolidated Resolution on the Construction of Vehicles (R.E.3) Annex 7, para. 2,
• amend paragraphs concerning production discontinuation to clarify that production is not considered definitively discontinued if vehicle manufacturers intend to obtain subsequent extensions of approval for software updates of vehicles already registered in the market,
• add new paragraphs requiring manufacturers to provide Technical Services with information on all hardware and software having an influence on performance,
• add new paragraphs allowing vehicle manufacturers to apply for new vehicle approvals to differentiate software versions for vehicles already registered in the market from those for new vehicles,
• add new paragraphs to approval forms requesting additional information regarding software identification and software updates, including whether Software Identification Number is held on the vehicle and relevant parameters for identification of vehicles that can be updated with the represented software.

Proposal to:

• Insert new paragraphs 0. and 0.1. to 0.1.4. providing introduction to the 01 series of amendments regarding vehicles of categories X and Y and alignment of provisions for all occupants,
• Amend paragraphs 0.1., 0.1.1., 0.1.3., 1.1. and 2.2., footnote 1 to define terms according to Consolidated Resolution R.E.3.,
• Amend paragraph 2.7. to define passenger compartment,
• Amend paragraph 4.4., footnote 2 to reference Consolidated Resolution R.E.3.,
• Amend paragraph 5.2.1. to require heating systems in each passenger compartment,
• Insert new paragraphs 12. and 12.1. to 12.2.4. providing transitional provisions,
• Amend Annex 5, paragraph 2. to establish surface temperature requirements and allow manufacturers to justify higher temperatures through safety concept demonstration,
• Amend Annex 5, paragraph 2.1. to limit surface temperature to 70°C for uncoated metal or 80°C for other materials,
• Delete Annex 5, paragraphs 2.2. and 2.3.,
• As from official entry into force, Contracting Parties shall not refuse type approvals under the 01 series,
• As from 1 September 2028, Contracting Parties shall not be obliged to accept approvals to the original version first issued after that date,
• Contracting Parties shall continue accepting original version approvals first issued before 1 September 2028 and equipment/parts approvals issued under the original version.

Proposal to amend UN Regulation No. 122 (Heating Systems). The 01 series of amendments takes into account vehicles of categories X and Y and aligns provisions in Annex 5 for all occupants. Surface temperature limits for heating systems apply equally to drivers and passengers regardless of seat position or vehicle category, with special care for rear seats of M₁ vehicles. Manufacturers may justify higher temperatures through a safety concept demonstrating no increased burn risk. Transitional provisions allow type approvals under preceding series until 1 September 2028. The proposal amends and supersedes ECE/TRANS/GRSG/2026/7.

Proposal from the GRSG task force on Automated Vehicles Regulation Screening to enable the application of UN R122 to ADS vehicles and to ensure that the requirements minimise the risk of burns across all vehicle occupants.
