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, and delete Annex 5, paragraphs 2.2. and 2.3. Transitional provisions apply: 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.

Proposal prepared by the Task Force on Automated Vehicles Regulatory Screening (TF-AVRS), with the aim to amend and supersede document ECE/TRANS/GRSG/2025/35.

Discussion on the general idea to align the contact surface temperatures with those for M2/M3 vehicles and to introduce the possibility for manufacturers to allow for higher contact surface temperatures if it can be demonstrated that their safety concept covers for higher temperatures without increasing the risk for occupantsto get burns.

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.

Proposal to introduce provisions for radiant warmers.

Proposal to amend the draft text to introduce provisions for radiant warmers into the regulation.

Proposal to align UN R122 to technological progress concerning the use of radiation warmers in electric vehicles. The radiation warmer is expected to increase energy efficiency of EV and is also able to prevent the sharp reduction of All Electric Range (AER).

Proposal to introduce a new definition for “radiant warmer”, to exclude such devices from the definition of “electric heater”, and to add a new safety requirement that such warmers must turn off immediately if there is contact with a vehicle occupant’s skin.

Proposal to add a missing footnote concerning the exemptions for heaters located outside the passenger compartment using water as a transfer medium and to clarify that it is not necessary to apply Annex 4 for the heat pump because the heat transfer fluid does not contain polluting air.

Proposal to add a missing footnote concerning the exemptions for heaters located outside the passenger compartment using water as a transfer medium and to clarify that it is not necessary to apply Annex 4 for the heat pump because the heat transfer fluid does not contain polluting air.

This proposal introduces transitional provisions into UN Regulation No. 122 should the proposals in document GRSG/2018/21 be adopted. GRSG/2018/21 would change the technical requirements for vehicles equipped with heat pump heating systems and therefore, transitional provisions would be applicable.

Proposal to clarify the requirements for electric heaters by limiting possibilities for exemptions applicable to interior heating systems supplied by several electrical elements.

Proposal to introduce provisions for interior heating systems using heat pumps.

Proposal to exempt all heaters located outside the passenger compartment and using water as a transfer medium from the requirements of the annexes on air quality and temperature. The current text only exempts combustion heaters.

Proposal to exempt all heaters located outside the passenger compartment and using water as a transfer medium from the requirements of the annexes on air quality and temperature. The current text only exempts combustion heaters.

Proposal to exempt any heaters (and not only combustion heaters as in the current text) located outside the passenger compartment and using water as a transfer medium are deemed to comply with the annexes on air quality and temperature.

Integrated into UN R122 as Amendment 3 as of 15 August 2012.
