Our testing lab performs testing in accordance with DIN EN SIO 17234-1 (Leather – Chemical tests – Determination of certain azo colorants which may release aromatic amines) competently and using an accredited procedure.
Using ISO 17234-1 test method, leather samples are chemically extracted and analyzed by chromatographic techniques to detect prohibited aromatic amines that may be released from azo dyes. The results obtained from this analysis ensure the safety and regulatory compliance of leather goods / products and support manufacturers in maintaining consistent quality assurence throughout their production processes.
The following chemical compounds are tested:
4-Aminobiphenyl, Benzidin, 4-Chlor-o-toluidin, 2-Naphthylamin, o-Aminoazotoluol, 5-Nitro-o-toluidin, 4-Chloranilin, 4-Methoxy-m-phenylendiamin, 4,4′-Methylendianilin, 3,3′-Dichlorbenzidin, 3,3′-Dimethoxybenzidin, 3,3′-Dimethylbenzidin, 4,4′-Methylendi-o-toluidin, 6-Methoxy-m-toluidin, 4,4′-Methylen-bis-(2-chloranilin), 4,4′-Oxydianilin, 4,4′-Thiodianilin, o-Toluidin, 4-Methyl-m-phenylendiamin, 2,4,5-Trimethylanilin, o-Anisidin, 4-Aminoazobenzol, 2,4-Xylidin, 2,6-Xylidin
