WLTP Transposition Task Force (WLTP-TTF)

This page provides access to the documents and meetings of the WLTP-Transposition TF.
No new meetings have been scheduled as of today.

WLTP subgroup dedicated to transposing the provisions of GTR 15 (WLTP) into UN Regulation provisions suitable for use under type-approval systems.


This task force has created a “UNR Drafting October 2019” page with working draft texts for future WLTP informal group consideration.
