Developed by the International Standards Organization (ISO), the ISO 17234-1 standard specifies a method for determining the use of certain azo colorants capable of releasing certain aromatic amines.
Certain azo colorants may, by reductive cleavage of azo groups, release one or more of the following aromatic amines listed in Annex 1907 of EU regulation 2006/8.
According to the available scientific knowledge, the use of prohibited azo colorants in the manufacture or processing of leathers is considered proven if the colored leather yields one or more of the specified amines under the conditions of this procedure. Applicable if the specified amount of one or any of these exceeds 30 mg/kg.
