29. The expert from ETRTO introduced ECE/TRANS/WP.29/GRRF/2014/25 concerning snow tyres for use in severe snow conditions, specifically the items to be listed in the communication form of Annex 1 to UN Regulation No. 117.

30. The expert from ETRTO presented GRRF-78-13 proposing a corrigendum to Supplement 2 to 02 series of UN Regulation No. 117. The proposal noted that the Supplement to UN Regulation No. 117 introducing limits for C2 tyres in paragraph 6.4.1.1. had been adopted after the parallel proposal introducing those for C3 tyres. It highlighted an unintended consequence whereby the limits for C3 tyre had been deleted. Following the discussion, GRRF agreed that, while the consequence was an error, it was not appropriate to correct the regulation using corrigenda and agreed to consider the proposal as a Supplement.

31. GRRF adopted ECE/TRANS/WP.29/GRRF/2014/25 as reproduced in Annex IV to this report, and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their March 2015 sessions as draft Supplement 7 to 02 series of UN Regulation No. 117.

32. The expert from the Russian Federation, Vice-Chair of the Working Party on Noise (GRB), informed GRRF that a revised version of ECE/TRANS/WP.29/GRB/2014/7, including some minor editorial amendments, had been submitted by GRB to WP.29 and AC.1 for consideration at their March 2015 sessions.
