Excerpts from session reports
WP.29 | Session 164 | 11-14 Nov 2014

[Vote postponed until the March session. The GTR allows option between semi-validated HILS and fully validated power pack methods. US EPA believes there must be a robust understanding of the correlation between the two methods and the testing to build this understanding is incomplete. Therefore, while the US is committed to the GTR amendment, the US requests a delay. Canada and Japan support this request and need for the additional data.]

27. The World Forum recalled the oral report of the Chair of GRPE given during the 163rd session (ECE/TRANS/WP.29/1110, paras. 32-36) and approved the report.

109. The representative of the United States of America kindly requested AC.3 to postpone consideration of draft Amendment 3 to UN GTR No. 4 (ECE/TRANS/WP.29/ 2014/84, ECE/TRANS/WP.29/2014/85 and the authorization to develop a corresponding amendment (ECE/TRANS/WP.29/AC.3/29)) because his country was still performing tests on the potential differences between the two alternatives in the proposed Annexes 9 and 10 and on their implications. He added that the test results would probably be shared with the other Contracting Parties at the January 2015 session of GRPE. The Chair noted that another Contracting Party also requested a delay in the vote until their clearance process had been completed. The Contracting Parties welcomed the statements and agreed to postpone consideration of the amendment and the vote by AC.3 to the March 2015 session.

GRPE | Session 69 | 5-6 Jun 2014

16. The secretary to the IWG on HDH introduced GRPE-69-12 and reported on the completion of the work. He presented GRPE-69-10 amending the proposal in ECE/TRANS/WP.29/GRPE/2014/11 introducing a novel approach for assessing the performance of the entire vehicle powertrain by a simulation (HILS) as well as the final technical report (GRPE-69-11) for the proposed Amendment 3 to UN GTR No. 4.

17. GRPE noted that the HILS method validation was only partially completed when applying the Japanese criteria but that none of the prerequisites were met for extending the mandate for further action by the IWG. Therefore, GRPE acknowledged the work done by the IWG and agreed to remove this item from the provisional agenda of the seventieth session of GRPE in January 2015.

18. GRPE adopted the proposal ECE/TRANS/WP.29/GRPE/2014/11 as amended by GRPE-69-10 and GRPE-69-22 (Part A) as reproduced in Addendum 2 to the GPE 68th session report. GRPE also adopted the corresponding technical report (GRPE-69-11 as amended by GRPE-69-22 (Part B), reproduced in Addendum 2) and requested the secretariat to submit them as a proposal for draft Amendment 3 to UN GTR No. 4 to WP.29 and AC.3 at their November 2014 sessions.

GRPE | Session 70 | 13-16 Jan 2015

22. The Chair of GRPE recalled the decision of WP.29 to defer the vote of the Executive Committee of the 1998 Agreement (AC.3) on ECE/TRANS/WP.29/2014/84 and ECE/TRANS/WP.29/2014/85 at its March 2015 session.

23. The expert from the USA presented GRPE-70-15 reporting on the activities of his Country on a correlation study comparing results obtained according to Annex 9 and those obtained according to Annex 10 (in ECE/TRANS/WP.29/2014/84). He offered to share the outcome of this study with GRPE in June 2015. GRPE welcomed this offer and agreed to further exchange information on the emissions of heavy duty vehicles equipped with hybrid powertrains and their environmental performance evaluation.

WP.29 | Session 165 | 10-13 Mar 2015

103. Submitted for consideration and vote, the proposal for Amendment 3 to draft UN GTR on Worldwide Heavy-Duty Certification procedure (WHDC) (ECE/TRANS/WP.29/2014/84, ECE/TRANS/WP.29/2014/85, ECE/TRANS/WP.29/AC.3/29, ECE/TRANS/WP.29/AC.3/38) was established in the UN Global Registry on 12 March 2015 by consensus vote of the following Contracting Parties present and voting: Australia, Canada, China, European Union (voting for Cyprus, Finland, France, Germany, Hungary, Italy, Lithuania, Luxembourg, Netherlands, Romania, Slovakia, Slovenia, Spain, Sweden and the United Kingdom), India, Japan, Norway, Republic of Korea, Republic of Moldova, Russian Federation, South Africa and United States of America.

[GAR note pending publication of official session report: Amendment 3 (documents WP.29/2014/84 and WP.29/2014/85) is unanimously adopted by the Contracting Parties present, including EU, USA, Japan, China, and others. US EPA notes a number of open issues concerning discrepancies in results achieved during extensive testing which will need to be resolved in the next phase of development. Nonetheless, the US reaffirms their belief that the test methodology is essentially sound and votes to adopt the amendment.]
