Proposal to enable the use of autonomous CNG heaters for the heating of engines before the vehicle is in service.
44. The expert from OICA presented GRSG-108-29 on the use of autonomous CNG heaters for the heating of the engines before the entry into service of the vehicle. The document received general support and a number of comments. GRSG agreed to resume consideration of this subject at its next session on the basis of an official document. The expert from OICA volunteered to submit in due time a revised proposal taking into account the comments received.
10. The expert from OICA presented ECE/TRANS/WP.29/GRSG/2015/33 proposing amendments to the provisions on the activation of a fire alarm system.

The secretariat was requested to submit the proposal to WP.29 and AC.1 for consideration at their March 2016 sessions, as part (see paras. 7 and 9 above) of draft Supplement 5 to the 06 series of amendments to UN Regulation No. 107.
35. The expert from OICA shortly introduced ECE/TRANS/WP.29/GRSG/2015/36 on autonomous CNG heaters for the heating of the engines, but he preferred to have a detailed consideration of the proposal at the next session of GRSG. GRSG endorsed that suggestion.
