Proposal of the ad hoc expert group on transitional provisions to clarify and update these terms within the heavy braking regulation, including provisions for extensions of type approvals granted according to the antecedent requirements of the original approval. These amendments also relate to the transfer of brake-related telltale provisions to UN R121.
11. The expert from UK reported on the outcome of the group of experts working on updated transitional provisions of UN Regulations Nos. 13 (GRRF-76-02) and introduced ECE/TRANS/WP.29/GRRF/2014/7. GRRF adopted this proposal as reproduced in Annex II to the session report and requested the secretariat to submit it to World Forum for Harmonization of Vehicle Regulations (WP.29) and the Administrative Committee of the 1958 Agreement (AC.1) for consideration at their June 2014 sessions as part of the draft Supplement 12 to the 11 series of amendments to UN Regulation No. 13.
13. At the request of the expert from Japan, GRRF agreed to take note that the consolidation of the transitional provisions does not change the interpretation of the current text of the Regulation (e.g. transitional provisions for supplements). GRRF agreed that the absence of the historical dates from the latest text simplified interpretation of the requirements for the purposes of issuing type approval. GRRF also noted that references to “registration” had been removed in favour of “national or regional type approval” as recommended by the guidelines in ECE/TRANS/WP.29/1044/Rev.1.
14. GRRF agreed to note in this report the meaning of “according to the basis of the requirement that existed at the time of the original approval” in para. 12.5. of ECE/TRANS/WP.29/GRRF/2014/7. In this context, GRRF agreed that “the requirement that existed” refers to those requirements applied at that time, taking into consideration of the transitional provisions.
