23. On behalf the GRB Ambassador to IWVTA, the expert from EC reported on the progress made on Revision 3 of the 1958 Agreement and on the development of UN Regulation No. 0. At its June 2014 session, WP.29 had agreed to freeze the work on Revision 3 and to resume its consideration in November 2014 on the basis of political and legal guidance that the Contracting Parties had been requested to provide, in particular, on outstanding issues of proxy voting and the three-fourth or the four-fifth majority required for taking decisions. WP.29 had also approved a questionnaire on IWVTA which was subsequently distributed. The latest draft of Revision 3 of the 1958 Agreement is contained in ECE/TRANS/WP.29/2014/53 and ECE/TRANS/WP.29/2014/82.

24. The secretariat presented draft guidelines on amendments to UN Regulations (WP.29-163-10), including a new term “version of a UN Regulation” and a common commencement date (1 September each year) recommended for new series of amendments to all UN Regulations listed in the annex of UN Regulation No. 0. In this respect, the Chair recalled that for the 03 series of amendments to UN Regulation No. 51, the date of entry into force of phase 1 was fixed on 1 July 2016, in order to synchronize it with the entry into force of EU Regulation No. 540/2014 on the sound level of motor vehicles and of replacement silencing systems (see para. 5 above).
