Proposal to correct a reference to standard IEC (pursuant to a change in paragraph numbering of the IEC standard) and to align UN R37 with UN R48 and UN R128 with regard to the use of the term “chromaticity area”. The wording “required tolerance area” in case of colour is changed to “required chromaticity area” to align with Regulation No. 48. This proposal was initiated by a proposal to amend Regulation No. 128 aimed at avoiding confusion with other tolerance areas.

15. The expert from GTB proposed an amendment to Regulation No. 37, which corrects an error and aligns a term with Regulation No. 128 (ECE/TRANS/WP.29/GRE/2017/19). GRE adopted the amendment as draft Supplement 46 to the 03 series of amendments and requested the secretariat to submit it to WP.29 and AC.1 for consideration and vote at their March 2018 sessions.
