New Oeko-Tex criteria go live

20/04/2012
New criteria and limit values published by the Oeko-Tex Association in January for tests on harmful substances for textiles according to Standard 100 came into force on April 1 2012 for all certification procedures.

According to the organisation the most important new regulations in its Criteria Catalogue 2012 are the following.

Synthetic fibres on which solvents are used during the spinning process, such as elastane and polyacrylic as well as coatings and polyurethane foams will now, with immediate effect, also be tested for N-methyl-pyrrolidone and Dimethylacetamide.

Relevant test samples such as coated items, plastic oil prints, flexible foam materials and accessories made of plastic will now be tested for four new softening agents: Di-C6-8-branched Dialkylphthalate, Di-C7-11-branched Dialkylphthalate, Di n hexylphthalate (DHP) and Bis(2-methoxyethyl)phthalate. These are integrated into the phthalates already listed in
Oeko-Tex Standard 100.

The limit value for extractable chromium is specified for leather products in product class IV (in which leather is used for decoration, as it is in many athletic shoes) at 10 mg/kg. This exception from the usual chromium limit values for textile items corresponds to the best available technology in the market, the organisation said.
