Proposal to revise the current mandate in order to respond to EU interest in further exploration of particle number emissions from spark ignition engines relating to particle size (reduction of the d50 cut off specification) and to emissions under rich operation conditions. The proposal further raises prospect for GTR transposition and/or work on particle emissions from tire/brake (friction material) wear.

Materials and adhesives used in the construction of vehicle interiors can emit volatile organic compounds(VOCs), aldehydes, or other substances that are harmful to human body. Korea, Japan, and China have legislation related to this subject and ISO 12219-1:2012 concerns the measurement of volatile organic compounds in cabin interiors. Many vehicle manufacturers have also addressed this issue. Therefore, Korea proposes that WP.29 undertake an effort to establish worldwide uniform standards to ensure healthy vehicle interior air quality (VIAQ).

Presentation on the aims of the proposal, to be considered at the June 2013 GRPE session, for a new UN Regulation concerning LPG (liquefied petroleum gases) or NG (compressed natural gas/bio‐methane/liquefied natural gas) dual fuel retrofit systems to be installed in heavy duty diesel applications.
