18. The expert from Japan introduced GRSG-107-10-Rev.1, superseding ECE/TRANS/WP.29/GRSG/2014/26 on the close-proximity field of vision. This proposal excludes close proximity devices for category M1 from the scope of the UN Regulation and allows Contracting Parties to limit the application of the scope of the UN Regulation to category M1 only. He added that the intention of his proposal was to allow Contracting Parties to keep their national requirements on close-proximity field of vision when UN Regulation No. 46 would be added to List A of the regulations to be included into the new UN Regulation No. 0. GRSG noted some concerns on the possible interpretation of the 1958 Agreement that could hamper the principle of reciprocal recognition of type approvals. GRSG agreed to resume discussion on this subject at its May 2015 session on the basis of revised proposal prepared by the expert from Japan in cooperation with interested parties.

22. The expert from Japan introduced GRSG-108-17-Rev.1, superseding ECE/TRANS/WP.29/GRSG/2014/26, on the close-proximity field of vision for certain categories of vehicles. GRSG welcomed the compromise proposal and noted general support on the modified scope of UN Regulation No. 46. GRSG adopted GRSG-108-17-Rev.1.

23. Referring to the final report GRSG-108-23, the expert from the Netherlands, chairing the Informal Working Group (IWG) on Camera-Monitor Systems (CMS), informed GRSG that his group had finalized the draft amendments to Regulation No. 46 to introduce the optional replacement of mirrors of Classes I to IV by camera-monitor systems (ECE/TRANS/WP.29/GRSG/2015/2). He added that all ISO standards referred to in the proposed text were accessible for GRSG experts as informal documents GRSG-108-03 and GRSG-108-20. On behalf of the informal group on CMS, he presented GRSG-108-21 incorporating further amendments to ECE/TRANS/WP.29/GRSG/2015/2. He proposed to insert supplementary information on camera-monitor systems of classes I to IV into the existing information documents required for type-approval procedure (GRSG-108-22).

24. GRSG adopted ECE/TRANS/WP.29/GRSG/2015/2, amended as reproduced in GRSG-108-46-Rev.2 (including the modified scope proposed in GRSG-108-17-Rev.1 and adopted under para. 22 above). The secretariat was requested to submit the adopted proposal to WP.29 and AC.1 for consideration at their November 2015 sessions, as draft Supplement 2 to the 04 series of amendments to UN Regulation No. 46.
