The criteria catalogue, which is based on international test standards and other recognised test processes, includes around 100 test parameters and is equally binding for all authorised OEKO-TEX® partner institutes. The measures and limit values contained therein are much more stringent than the valid national and international specifications and include:
- important statutory regulations such as, for example, banned AZO colouring agents, chromium (VI), PFOS, lead (US-CPSIA) etc.
- requirements of annexes XVII and XIV of the REACH regulation and the ECHA SVHC Candidate List
- numerous chemicals that are harmful to health, even if they have not yet been legally regulated
- numerous environmentally relevant substance classes
The more intensively an article comes into contact with the skin, the stricter the human-ecological requirements that it must fulfil. LEATHER STANDARD identifies four product classes:
Product class I: Articles for babies and children up to 3 years of age
Product class II: Articles used close to the skin
Product class III: Articles used away from the skin
Product class IV: Decorative materials
A special regulation within the LEATHER STANDARD only permits the certification of the following skins:
- cattle and cowhide
- horse leather
For components of an article that are made of textile or metal fabrics, not of leather, the conditions of the current STANDARD 100 are applied.
Chemicals, auxiliaries and colourants are tested and certified in accordance with ECO PASSPORT by OEKO-TEX®, not the LEATHER STANDARD.
