Leather. Chemical tests for the determination of certain azo colorants in dyed leathers - Determination of 4-aminoazobenzene Ingestion-build-89079 BS EN 1295-1 covers pipes1 Scope This part of ISO 17234 is supplementary to ISO 17234 1 and describes a special procedure to detect the use of certain azo colorants in commodities, which can release 4 aminoazobenzene. The procedure also detects 4 aminoazobenzene (Solvent Yellow 1) which is already available as free amine in commodities without reducing pretreatment. Azo colorants that are able to form 4 aminoazobenzene generate, under the conditions of ISO 17234 1, the amines
