15. The expert from OICA presented a revised proposal with the aim to clarify the scope and some provisions of UN Regulation No. 138 (GRB-69-06). GRB adopted the proposal, as laid down in Annex II and requested the secretariat to submit it to WP.29 and AC.1 for consideration and vote at their June 2019 sessions as a draft Supplement 1 to the 01 series of amendments to UN Regulation No. 138.

18. The expert from OICA proposed to clarify the application of the 01 series of amendments to Regulation No. 138 (GRB-67-09). The experts from China, France, Germany, OICA and WBU commented on the proposal. The secretariat pointed out that it had already rectified the text of paragraph 6.2.6. which had been incorrectly reproduced in a revised consolidated version published on the WP.29 website (E/ECE/324/Rev.2/Add.137/Rev.1 − E/ECE/TRANS/505/Rev.2/Add.137/Rev.1). GRB invited OICA to take into account the comments received and to prepare an official document for consideration at the next session. GRB also requested that the earlier OICA proposals for transitional provisions (ECE/TRANS/WP.29/GRB/2017/7) be included into this new document.
