Draft Guidelines for application of the Unique Identifier (UI)
WP29 IWG IWVTA - SG Rev1
Proposal to amend Annex 1
Taking into account:
The original proposal in SG Rev1
The proposal in SG (Japan) clarifying the situation concerning extensions to approvals relating to a mix of products having different performance levels.
The amendment proposed in DETA-31-04Rev.1 –GRE IWG-SLR
Comments noted during the discussion of DETA-31-04Rev.1 –GRE IWG-SLR in the IWVTA -26 Session 09 March The IWVTA experts agreed with the basic approach proposed by GRE IWG-SLR but suggested that the proposed wording may be difficult to understand by anyone unfamiliar with the detail of the preceding discussions. IWG-SLR was invited to divide the line 5 of the table in Annex 1 into two sections.
The following version of the table divides the line 5 into two parts, resulting in the renumbering of the sections.
Additionally the table has been reformatted to show the differentiation between the cases applicable to the text of the original series of amendments and a subsequent series.
