WP.29/2014/30
Proposal for the development of amendments to GTR No. [15] on the Worldwide harmonized Light vehicles Test Procedures (WLTP) (EU and Japan)
Proposal for the development of amendments to GTR No. [15] on the Worldwide harmonized Light vehicles Test Procedures (WLTP)
Proposal for a further “phase 1b” in the development of the GTR on light vehicle emissions. In order to meet Contracting Party objectives, the draft GTR has been submitted for adoption by the Forum in March 2014. Although the current draft offers a complete test cycle, the WLTP experts want to improve the regulation by further addressing a number of technical elements that were set aside due to time and resource constraints.
