32. GRE considered ECE/TRANS/WP.29/GRE/2012/11, tabled by the expert from GTB, defining the conditions under which voltage control gear may be used in conjunction with filament light sources. The expert from IEC introduced GRE-67-17 and GRE-67-30, raising some concerns to the proposal. GRE noted that the experts from Germany and the Netherlands raised their objection to a general voltage variation of filament lamps. GRE adopted ECE/TRANS/WP.29/GRE/2012/12, not amended, and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their November 2012 sessions as part of draft Supplement 10 to the 04 series of amendments to UN Regulation No. 48 (see paras. 7, 12, 13, 14, and 28) and as part of draft Supplement 4 to the 01 series of amendments to UN Regulation No. 112 (see paras. 24, 29, 30 and 31).
