Proposal to clarify the definition of “‘on’ time” (t_H) to address cases where a single flash consists of several flashes.

38. The expert from Poland proposed to clarify the definition of the “on” time for the case of a group of flashes (GRE-82-09). The expert from GTB pointed out that the GTB Working Group Photometry had recently considered an alternative wording for the same purpose. GRE invited both experts to submit a new proposal to the next session.

Proposal for corrections to UN Regulation 65 (Special Warning Lamps) based upon Supplement 10 to the original Regulation. A recent review of the content of UN Regulation 65 has revealed some long-standing editorial errors that do not affect the technical requirements but do create confusion.

39. The expert from GTB proposed corrections (ECE/TRANS/WP.29/GRE/2019/17). GRE supported the amendments but decided to postpone their submission to WP.29 and AC.1, in order to combine them with the results of the discussion reflected in the previous paragraph.

38. The expert from GTB submitted an amendment proposal with the aim to clarify the definition of the “on” time for a group of flashes as well as to correct editorial errors (ECE/TRANS/WP.29/GRE/2020/18). GRE adopted this proposal and requested the secretariat to submit it for consideration and vote at the March 2021 sessions of WP.29 and AC.1 as draft Supplement 11 to the original series of amendments to UN Regulation No. 65.

39. GRE also recalled that, at its previous session, it had adopted the corrections proposed by GTB (ECE/TRANS/WP.29/GRE/2019/17) but had postponed their submission to WP.29 and AC.1, in order to combine them with the results of the discussion reflected in the previous paragraph.
