Documents GRE/2014/20, GRE/2014/24 and GRE/2014/29 propose to add light categories to UN Regulation Nos. 37, 99, and 128; however, since the amendment or extension of an IEC60061 cap sheet results in a change to the sequence number of the sheet, all light source category sheets that refer to that IEC sheet need an update. Therefore, the IEC proposes the necessary changes to the text of the above proposals.
