UN R140: Proposal for Supplement 1
Document WP.29/2018/61
3 April 2018

Proposal to remove “if fitted” language from the text to clarify that UN R140 can only be applied to a vehicle equipped with a ESC system. UN R140 was originally established through the extraction of electronic stability controls (ESC) provisions from UN R13-H on brake systems. Within the context of UN R13-H, the ESC provisions were written to assess performance in cases where a vehicle was fitted with an electronic stability control system. As a stand-alone regulation, however, UN R140 applies only to vehicles that are equipped with ESC. The proposal also would correct an apparent error in to Annex 4, paragraph 2.1. where the reference to “ISO 15037 Part 1:2005” should read “ISO 15037 Part 1:2006”.

Insert the missing amendment to former paragraph 3.2.10, to read:

"3.2.11.An indication, by means of the “PSI” index (as explained in Annex 7, Appendix 2 to this Regulation) or in kilopascals (kPa), of the inflation pressure to be adopted for the load/speed endurance tests. This indication may be placed on one sidewall only."

Annex 7, paragraph 1.3., amend to read:
“1.3.Inflate the tyre to the pressure corresponding to the indication on the sidewall as specified in paragraph 3.2.11. of this Regulation.”

12. The expert from Australia presented ECE/TRANS/WP.29/GRRF/2018/2 and ECE/TRANS/WP.29/GRRF/2018/3 clarifying the obligation for the vehicle type to be equipped with a Brake Assist System (BAS) or an Electronic Stability Control (ESC) system in order to receive a type approval according to UN Regulation No. 139 or UN Regulation No. 140 respectively. GRRF supported both proposals and requested the secretariat to submit them to WP.29 and AC.1 as draft Supplements 1 to UN Regulations Nos. 139 and 140 for consideration and vote at their June 2018 sessions.
