83. The representative of the Russian Federation, Co-Chair of the IWG on PTI, updated the World Forum on the work of the group (WP.29-173-06). He reported to the World Forum on the eighth meeting of the IWG on PTI that was held on 24 October 2017 in Brussels. He explained that the IWG on PTI decided to propose amendments to ECE/TRANS/WP.29/2017/134 under agenda item 7.4 as reproduced in WP.29-173-12. He recalled the proposal made by the representative of Finland and Sweden at the 172nd session of WP.29, that were similar to the earlier proposals presented by the Russian Federation (WP29-147-11 and WP29-165-07) aimed at including PTI relevant provisions in UN Regulations. He mentioned that the group had considerations related to the 1958 Agreement and the new concept “Whole Life Vehicle Compliance” was suggested. He reported on the considerations of the group as a follow-up on the presentation made by the representative of Switzerland on the tampering truck emissions tampering at the June 2017 session of WP.29 and possible benefits of PTI in this context.

87. The representative of the Russian Federation, Co-Chair of the IWG on PTI, presented ECE/TRANS/WP.29/2017/134 that proposes the establishment of a new Rule on Periodical Technical Inspections of motor vehicles using Compressed Natural Gas (CNG) and/or Liquefied Natural Gas (LNG) in their propulsion system, that would be annexed to the 1997 Agreement. He also introduced informal document WP.29-173-12 amending the proposal by adding vehicles using Liquefied Petroleum Gas (LPG). Some Contracting Parties indicated that they were still in the process of evaluating the proposal.

89. WP.29 recommended the submission of the two proposals to AC.4 for voting, noting that some European Contracting Parties would support, in principle, the proposals but felt not in the position to adopt these proposals due to possible inconsistencies with European Directives on PTI on these matters (not specifically addressing additional test items for gas fuelled vehicles and hybrid vehicles).

158. No further supplementary information was provided beyond agenda item 7.4. (see paras. 81-83 above).
