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.

4. The Chair of the informal working group on “Alternative Method to assess the Electronic Vehicle Stability Control system” (AMEVSC) reported on the progress made by the group on using test reports, e.g. according to various annexes of UN Regulation No. 13. He introduced GRRF-74-07, reporting on the work accomplished and the conclusion of the group on the rights and obligations when using a test reports procedure (e.g. as defined in Regulation No. 13, Annex 19) linked to the 1958 Agreement. GRRF endorsed these conclusions. The summary of these conclusions is listed in the form of a table in Annex III to this report.

5. The Secretary to the informal working group on AMEVSC introduced GRRF-74-06 on the use of a simulation tool as an AMEVSC, amending ECE/TRANS/WP.29/GRRF/2013/10 and especially the justification section. GRRF adopted this proposal as amended below. GRRF requested the secretariat to submit the proposal to WP.29 and AC.1 for consideration at their June 2013 sessions as part of the draft Supplement 10 to the 11 series of amendments to Regulation No. 13.

Annex 21, Appendix 1, paragraph 1.4., amend to read:

“1.4. The availability of the simulation tool software, to the software version used, shall be maintained for a period of not less than 10 years following the date of the approval of the vehicle.”

Annex 21, Appendix 2, footnote 1, amend to read:
