The purpose of this proposal is to update the reference to the latest version of the ISO 10844 and to introduce transitional provisions for the shift of the test track requirements from ISO 10844: 1994 to ISO 10844: 2014. This proposal supersedes document GRB/2015/5.

Proposal to update and clarify the text of UN R28.

In response to concerns that approval agencies may not grant manufacturers the additional 1dB for L(wot) on conformity of production tests as changes had been made to Annex 6 of R41-04, GRB issued an interpretation recorded in the report of its 56th session. However, IMMA believes that industry and agency personnel may still not be aware of the interpretation. Therefore, IMMA proposes to codify the interpretation within UN R41.
