This collective amendment on the stability of photometric performance during the heat test, with particular reference to the movement of the cut-off line, clarifies the test cycle and also aligns the requirements of Regulations Nos. 19, 98, 112, 113 and 123. In addition to resolving problems of interpretation presented by the current text, this collective amendment will assist the Informal Working Group “Simplification of Lighting and Light-Signalling Regulations” in drafting the new simplified Regulations which is underway.

15. The expert from GTB proposed to clarify the heat test cycle relating to the movement of the passing beam cut-off in Regulations Nos. 19, 98, 112, 113 and 123 (ECE/TRANS/WP.29/GRE/2016/32). The experts from EC and UK expressed concerns that the proposals would modify the performance requirements and might have safety implications. Therefore, these experts felt that the proposals should be formulated in the form of new series of amendments to the above Regulations, rather than supplements. The experts from Finland, France, Germany, Japan, GTB and OICA advocated for supplements and pointed out that the proposed amendments would neither raise the required level of stringency nor have safety implications. Finally, GRE adopted the proposals and requested the secretariat to include them into the package for submission to WP.29 and AC.1 for consideration and vote at their March 2017 sessions (see para. 10 above).

Proposal to:

1. correct provisions on bend lighting for motorcycles adopted by WP.29 as Supplement 2 (document WP.29/2012/83),
2. reference the compliance requirements for installation contained in Regulations Nos. 48, 53, 72 and 86,
3. clarify the definition of “type”, with regard to manufacturer, trade names and marks,
4. introduce editorial improvements to the requirements for markings,
5. amend the formula for the dirt mixture used in testing to address an error introduced by Supplement 9 to the 01 series of amendments to UN R45,
6. clarify the test cycle with regard to the stability of photometric performance during the heat test, with particular reference to the movement of the cut-off line, and
7. harmonize related requirements across Regulations Nos. 19, 98, 112, 113 and 123.

73. The representative of EU expressed concerns (WP.29-171-04) about the legal form of amendments relating to the heat test cycle requirement in Regulation No. 113, as contained in ECE/TRANS/WP.29/2017/39 (agenda item 4.9.21). The World Forum decided to refer this document back to GRE for further consideration.

35. GRE took note that, at the March 2017 session of WP.29, the representative of EU expressed concerns (WP.29-171-04) about the legal form of amendments relating to the heat test cycle requirement in Regulation No. 113, as contained in ECE/TRANS/WP.29/2017/39. WP.29 had decided to refer this document back to GRE for further consideration (ECE/TRANS/WP.29/1129, para. 73). GRE agreed that the underlying proposals should be introduced as a new series of amendments and adopted a revised text, as contained in Annex V. The secretariat was requested to submit it to WP.29 and AC.1 for consideration and vote at their June 2017 sessions.

Proposal to:

1. correct provisions on bend lighting for motorcycles adopted by WP.29 as Supplement 2 (document WP.29/2012/83),
2. reference the compliance requirements for installation contained in Regulations Nos. 48, 53, 72 and 86,
3. clarify the definition of “type”, with regard to manufacturer, trade names and marks,

5. amend the formula for the dirt mixture used in testing to address an error introduced by Supplement 9 to the 01 series of amendments to UN R45,
6. clarify the test cycle with regard to the stability of photometric performance during the heat test, with particular reference to the movement of the cut-off line, and
