Proposal to clarify the treatment of extensions of existing approvals under the new transitional provision guidelines (“Until 31 December 2019, Supplement 2 to the 01 series of amendments to this Regulation may not apply to extensions of approvals that were originally granted prior to the entry into force of Supplement 2.”)

UN R121: Proposal for Supplement 10 to the original series of amendments and Supplement 2 to the 01 series of amendments
Proposal pursuant to discussions on the application of footnote 18 under Table 1 concerning tell-tale symbols and the use of colours to convey different meanings. ISO standard 2575-2004, para. 5.1. allows for the use of different colours to convey a change in the operating condition. This proposal would remove the current footnote 18 text and application of the footnote to telltales 2, 9-12, and 19 pending a decision on the proposal to apply a revised footnote to the master lighting switch (tell-tale 1). Paragraph 5.4.1.1. of UN R121 references ISO 2575-2004 which was developed to simplify the application of UN R121 when colour changes are adopted in other UN Regulations; however, OICA submits that the footnote which references ISO 2575-2004 in relation to specific lighting devices or systems creates a degree of confusion. (If approved, this proposal would likely impact Supplement 3 to the 01 series rather than Supplement 2 given that WP.29 at its November 2017 session adopted the proposal to add a telltale and symbols for “Accident Emergency Call System (AECS)” and to align UN R121 with the 07 series of amendments to UN Regulation No. 16 as Supplement 2 to the 01 series.)
