58. The expert from OICA introduced ECE/TRANS/WP.29/GRRF/2016/4 proposing to remove the TPMS requirements from Regulation No. 64 as suggested by the IWG on IWVTA. He presented ECE/TRANS/WP.29/GRRF/2016/5 proposing a new Regulation on TPMS. Following discussion, GRRF agreed on the proposals as amended and reproduced in GRRF-81-21 and GRRF-81-22.

59. The expert from EC proposed amendments (GRRF-81-17) to ECE/TRANS/WP.29/GRRF/2016/5 clarifying that the manufacturer has the obligation to design a TPMS system which shall detect underinflation under a wide range of driving conditions and not only in the conditions of the test procedures in Annex 3 of the Regulation. GRRF adopted with the proposal as amended (GRRF-81-17-Rev.1). GRRF noted that the agreed proposal would not modify the test procedures as described in Annex 3 of the Regulation. The expert from the Russian Federation and some type-approval authorities raised a question about general provisions in UN Regulations for which no procedure was defined to verify the compliance with these general provisions for manufacturers. GRRF suggested that WP.29 could have a general discussion on the compliance off the test procedures and could provide guidance to the WP.29 subsidiary bodies.

60. GRRF adopted ECE/TRANS/WP.29/GRRF/2016/4 as amended by Annex X of the report and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their June 2016 sessions, as draft 03 series of amendments to Regulation No. 64.

61. GRRF adopted ECE/TRANS/WP.29/GRRF/2016/5 as amended by Annex XI of the report and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their June 2016 sessions.
