Proposal as approved by the GRRF to clarify provisions on the use of Combined Braking Systems (CBS) and make some additional editorial improvements.
57. Agenda item 4.7.4, Regulation No. 78, ECE/TRANS/WP.29/2015/9, correct to read:
Paragraph 5.1.9., correct the wording “brake a common” to read “brake, a common”.
Annex 3, paragraphs 4.2.(c), 5.2.(c) and 9.3.1.(c), correct the wording "single control" to read "single brake control".19. The expert from IMMA presented GRRF-79-16, proposing Electromagnetic Compatibility (EMC) requirements to be introduced in Regulation No. 78. The proposal received some comments. The expert from EC recommended to consider the existing wording applied to other vehicle categories (ECE/TRANS/WP.29/GRRF/2013/13). The expert from IMMA volunteered to prepare a revised proposal for the September 2015 session of GRRF.
20. The expert from EC introduced GRRF-79-16, proposing to apply to tricycles the existing Anti-lock Braking Systems (ABS) requirements for Powered Two Wheelers (PTWs). The proposal was accepted in principle as it proposed a harmonization with the corresponding EU directive. As the proposed wording would also affect other L-category vehicles, the expert from EC volunteered to prepare a revised proposal for the September 2015 session of GRRF.
19. The expert from IMMA introduced ECE/TRANS/WP.29/GRRF/2014/21 based on GRRF‑76‑45, proposing general clarifications to UN Regulation No. 78 and specific requirements for the use of Combined Braking Systems (CBS) and the parking brake. He added that the amendments contained in the proposal have been aligned with those proposed for the Global Technical Regulation No. 3 below. GRRF adopted this proposal and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their March 2015 sessions as draft Supplement 2 to the 03 series of amendments to UN Regulation No. 78.
20. The expert from EC introduced GRRF-78-06, supplementing document ECE/TRANS/WP.29/GRRF/2014/21, aimed at establishing technical requirements for ABS systems that are temporarily disabled e.g. in off-road conditions. The expert from Australia offered to provide further data from their current study on this issue. Following the discussion, GRRF agreed to revisit this item at its February 2015 session on the basis of a revised proposal jointly prepared by EC and IMMA.
