28. The expert from the Netherlands presented ECE/TRANS/WP.29/GRSG/2011/22 (superseding GRSG-100-13) proposing the concept of extension in the communication form of Regulation No. 61 (External projections of commercial vehicles). GRSG noted that a concrete proposal (ECE/TRANS/WP.29/2011/152) on this subject was on the agenda of the November 2011 session of WP.29 (see WP.29 report: ECE/TRANS/WP.29/1093, para. 51). GRSG agreed to resume consideration of the matter at its next session on the basis of a revised proposal by the Netherlands, taking into account the final decision of WP.29.

32. Referring to the discussion at the previous session of GRSG on ECE/TRANS/WP.29/GRSG/2011/22, the expert from the Netherlands presented GRSG-102-28 (superseding GRSG-102-05) clarifying in UN Regulation No. 61 the communication form to include withdrawal and extension of approvals. GRSG adopted the proposal, as reproduced in Annex V to this report, and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their November 2012 sessions, as part (see para. 21 above) of draft Supplement 2 to UN Regulation No. 61. The Chair reminded GRSG experts to include, if appropriate, into their proposals provisions for the withdrawal and extension of approvals, when preparing an amendment to an existing UN Regulation.
