31. GRE considered ECE/TRANS/WP.29/GRE/2011/46 tabled by the expert from GTB to update the test requirements. A number of experts wondered whether parts of private standards covered by copyrights could be reproduced in a Regulation. The GRE Chair agreed to seek guidance from WP.29 at its November 2011 session. GRE agreed to consider again ECE/TRANS/WP.29/GRE/2011/46 at its next session.

38. GRE resumed consideration of ECE/TRANS/WP.29/GRE/2011/46, tabled by the expert from GTB, updating the test requirements. GRE noted that the discussion on integrating private standards in WP.29 was postponed to the June 2012 session. GRE agreed to keep this agenda item for the October 2012 session. GRE also invited the experts from GTB and CLEPA to combine ECE/TRANS/WP.29/GRE/2011/46 and GRE-67-12, if possible (see para. 39).

39. The expert from CLEPA introduced GRE-67-12, enabling the combination of the two separate optically active stripes of the advance warning triangle into one. GRE agreed to continue discussion on this issue at its October 2012 session and requested the secretariat to distribute GRE-67-12 with an official symbol. GRE also invited the experts from GTB and CLEPA to combine ECE/TRANS/WP.29/GRE/2011/46 and GRE-67-12, if possible (see para. 38).

34. The expert from GTB introduced ECE/TRANS/WP.29/GRE/2013/49 as amended by GRE-70-03 and GRE-70-25, updating tests requirements of UN Regulation No. 27. GRE adopted this proposal as amended by Annex VII to the session report. GRE requested the secretariat to submit it to WP.29 and AC.1 for consideration at their March 2014 sessions as part of the draft 04 series of amendments to UN Regulation No. 27.

36. The expert from GTB informed GRE about the work progress made by its organization on this matter, combining the approach from CLEPA (ECE/TRANS/WP.29/GRE/2012/25) and GTB (ECE/TRANS/WP.29/GRE/2011/46). GRE agreed to reconsider this agenda item at its October 2013 session on the basis of a formal document that the expert from Germany volunteered to prepare.
