Agenda Item 17.3.
Gtr No. 4 (Worldwide Heavy-Duty Certification procedure (WHDC))

93. The representative of EU reported on the IWG which had completed its mandate in due time. The representative of the United States of America proposed that some additional work should be envisaged. AC.3 agreed to first consider, at its November 2014 session, the draft Amendment 3 adopted by GRPE in June 2014 and, then, to investigate remaining issues to define a mandate for a second phase for the IWG. AC.3 reconfirmed the adoption of ECE/TRANS/WP.29/AC.3/38 on the extension of the IWG mandate.

WP.29/AC.3/29 Proposal for the development of either amendments to gtr No. 4 adding a new emission test procedure for heavy-duty hybrid vehicles (HD-HV’S) or a new gtr (EU)
WP.29/AC.3/38 Authorization to extend the scope of the HDH informal group mandate to include alignment of GTR No. 4 and No. 11
