Document Title UN R121: Proposal for Supplement 3 to the 01 series of amendments
Reference Number WP.29/2018/26
Date
6 Jan 2018
Summary Proposal to apply footnote 18 to the symbol for tell-tale No. 1 (master lighting switch) in order to simplify the treatment of colour changes of tell-tales. Footnote 18 specifies "“Symbol may be shown in other colours than specified in column 5 in order to convey different meanings according to the general colour coding as proposed in paragraph 5. of ISO 2575-2004.” This proposal clarifies the existing understanding of the intent of the regulation and in particular addresses concerns over interpretation where tell-tales Nos. 1 and 19 have been combined.
