11. The expert from OICA introduced a proposal for editorial corrections to Regulation No. 13 (GRRF-73-02). GRRF agreed to two of the three proposed changes and adopted the proposal as reproduced in Annex 3 to this report. The secretariat was requested to submit it to WP.29 and AC.1 for consideration at their March 2013 session as Corrigendum 2 to UN Regulation No. 13.

12. GRRF noted the state of discussions in WP.29 on dynamic or static references to other UN Regulations and private standards. GRRF welcomed the recommendation to proceed on a case by case approach. The expert from Japan introduced a proposal to insert in Regulations Nos. 13 and 13-H a reference to Regulation No. 10 and its 04 series of amendments. The experts from OICA and CLEPA proposed to make a reference to the 03 series, as the 04 series only defines new requirements for hybrid electric vehicles (HEV) and electric vehicles (EV) vehicles. OICA recalled the purpose of ECE/TRANS/WP29/GRRF/2011/34 and especially the justification part. GRRF agreed to resume the discussion at its next session. For this purpose, the Chair requested the secretariat to distribute GRRF-73-14 with an official symbol, to keep ECE/TRANS/GRRF/2012/21 and to reinsert ECE/TRANS/GRRF/2011/34 on the agenda.

13. The expert from Belgium recalled the work progress (GRRF-73-09) made by the informal group on AMEVSC proposing updated provisions of Annex 21 (and its appendix) to UN Regulation No. 13 dealing with the use of simulation tools duly validated to prove compliance of the vehicle stability function (ECE/TRANS/WP.29/GRRF/2012/2). The Secretary introduced GRRF-73-06. GRRF was supportive of the proposal but raised some detailed issues. The Chair invited GRRF to provide the Secretary of the informal group with written comments to allow a revision to be prepared as an official document for consideration by GRRF at its next session .

14. The Chair recalled the purpose of ECE/TRANS/WP.29/GRRF/2012/11 and GRRF-72-28 on the introduction of an electro-hydraulic transmission for electrical brake systems. The expert from the Netherlands reported on a first meeting with Germany and his intention to produce an enhanced proposal for consideration at the next session. GRRF agreed to resume the discussion at its next session, keeping these documents as a reference.
