WP.29/2020/63
UN R83: Proposal for Supplement 11 to the 07 series of amendments

Proposal to introduce provisions to avoid the burden of a new road load determination (e.g., NEDC) in cases where the road load has already been performed under GTR 15 (WLTP), to amend provisions on On-Board Diagnostics (OBD), road load coefficient determination, mono fuel gas vehicles pursuant to WLTP, and to introduce definitions for the terms “permanent” and “Limp-home routines”, and to clarify “permanent emission default modes”.
