| Summary | Proposal to clarify the purpose of UN R139 which was originally established through the extraction of brake assist system (BAS) provisions from UN R13-H on brake systems. Within the context of UN R13-H, the BAS provisions were written to assess performance in cases where a vehicle was fitted with a brake assist system. As a stand-alone regulation, UN R139 applies only to vehicles that are equipped with BAS. Therefore, this supplement proposes to refine the text to remove the "if fitted" language and ensure that UN R139 can only be applied to a vehicle equipped with a BAS. | ||||||||

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. |

There cannot be a regulation dedicated to a technology with an "if-fitted" clause. If a manufacturer is applying for approval, they obviously have the technology on the vehicle. OICA interprets "if fitted" to mean that a CP does not have to mandate the technology, but can still use the regulation in cases where the technology is optional. Frost says CP can first decide whether to sign the regulation. Then whether just to accept approvals. Then whether to require technology. Frost does not see "if fitted" as changing this and agrees that you cannot apply the BAS regulation to a vehicle without BAS. OICA still concerned that under IWTVA a CP may interpret "shall" to mean mandatory installation. Guichard says that's issue for UN R0, not UN R142--component regulation specifies provisions for approval of a system and its installation on a vehicle. Bocharev says OICA concern is about implementation of regulation, not the regulation itself.
