Document GRVA-17-49 from the September 2023 GRVA session.

Copy of document GRVA-17-49.

Information document to inform GRSG of the proposal to introduce provisions for the specifications and calibration procedure of the 3-D “H”-point machine and the procedure for determining the “H”-point and the actual torso angle for seating positions in motor vehicles, to be used in all referenced UN Regulations and GTR. The proposal will be formally considered by GRSP in December 2023.

Proposal to delineate the scope of UN R79 vis-à-vis the draft new UN Regulation on Driver Control Assistance Systems (DCAS).

Proposal to clarify the need to apply, when relevant, the Type IIA test in Annex 15 for alternative brake lining purposes (e.g., in the case of vehicles with regenerative braking for Type IIA endurance test purposes to use the friction brake as an alternative to the regular endurance brake).

Proposal to introduce provisions for identification of buses and trucks equipped with an electric drivetrain consistent with existing regulated identification for Liquified Petroleum Gas (LPG), Compressed Natural Gas (CNG), Liquid Natural Gas (LNG) and Compressed Hydrogen (H2) fueled trucks and buses.

Small group (France, Netherlands, ETRTO, BIPAVER) proposal to restructure retreaded tyre requirements and regulations.

31. The expert from the small group on retreaded tyres reported on their activities (GRBP-78-29) and briefly introduced the solution envisaged by the group:

• Adoption of a new UN Regulation for type approval of retreaded tyres with regard to their snow performance without changing the technical requirements compared to the current text of UN Regulation No. 109 (GRBP-78-31), and
• Adoption of a new 01 series of amendment to UN Regulation No. 109 without the snow performance, with the aim to clarify the administrative requirements after a certain period with adequate transitional provisions (GRBP-78-30).

32. GRBP invited all experts to study both options and to provide their feedback to the small group on retreaded tyres, with a view to preparing for the next session a working document which would contain a draft new UN Regulation and amendments to both UN Regulations Nos. 108 and 109.

Proposal from a small group effort for uniform provisions concerning the approval of pre-cured tread materials which are used for producing retreaded tyres or the approval of retreaded tyres produced by using mould cure process with regard to their snow performance.

This document summarises the reviews conducted by the GR working parties on the fitness for ADS of UN Regulations and GTR for application to ADS vehicles. This document represents the current opinions of the experts at the time of submission, and the recommendations contained inside may evolve significantly during the next steps of the process of reviewing and amending Regulations.

Proposal to clarify the application of UN R10 on electromagnetic compatibility requirements to ALKS.

50. The representative of the Netherlands introduced GRPE-89-13 on the topic of PM emissions from cooling units on refrigerated vehicles and asked input and information from the GRPE and request the possibility to start an IWG to develop a new Regulation. The Chair informed GRPE the topic of cooling units was already on the GRPE emission topics list (GRPE-87-55) and welcomed concrete activities on the issue.

51. The representative of the UK informed GRPE some testing activities were on-going in the country with first phase to be concluded in Summer 2023.

52. The representative of OICA opened the topic to also think about refrigerated vehicles that have no separate cooling unit, for which some excess emissions might be justifiable, and added more evidence would be needed to fully capture the scale of the issue. He recognized covering the topic with such broader view was beyond the scope of the proposal introduced by the Netherlands and invited GRPE to also reflect on the topic.

53. The representative of India highlighted India was looking at the emission of such engines, sometimes also used for other purposes. He welcomed the initiative of the Netherlands and mentioned his willingness to stay informed about any forthcoming activities.

54. The Chair invited GRPE to start thinking about the creation of a dedicated informal working group on the topic in order to prepare proposal to limit harmful emissions from such engines.
