UN R85: Proposal for Supplement 9
Document WP.29/2019/44
11 April 2019

Proposal to reduce testing burdens by introducing an alternative test method to “decrease the charge air cooler outlet temperature by the same amount that the ambient conditions for the vehicle test varied from the standard temperature.” This aligns with SAE J1349, “9.3 Application of Vehicle Transient Data to Net Power Test.”

38. The expert from OICA presented ECE/TRANS/WP.29/GRPE/2019/7 proposing to amend, in UN Regulation No. 85, the wording of the description of auxiliaries to be fitted for testing to reduce potential testing burden. The experts from Netherlands, France, UK and EC did not see the benefit in some part of the proposal and would only support the proposed amendments contained in the first paragraph of the proposal. GRPE adopted ECE/TRANS/WP.29/GRPE/2019/7 as amended by Annex IX.

39. GRPE requested the secretariat to submit Annex IX of the report to WP.29 and the AC.1 for consideration and vote at their June 2019 sessions as draft Supplement 9 to UN Regulation No. 85.
