STANDARD 100 by OEKO-TEX® is an independent product label for all types of textiles tested for harmful substances – from yarns and fabrics to the ready-to-use items that you can buy in the shops.
Textile products are awarded the STANDARD 100 label if, on the basis of the extensive OEKO-TEX® criteria catalogue, they have been successfully tested by one of the OEKO-TEX® member institutes for chemicals that pose a health risk, and therefore contribute to an effective consumer protection.
The STANDARD 100 by OEKO-TEX® label can be issued for textile products from all stages of production (yarns, fabrics, dyed or finished materials, accessories) as well as for all kinds of sales articles such as baby textiles, garments, home textiles or furnishings for decorative purposes.
Product certification according to STANDARD 100 by OEKO-TEX® is only possible if all components of an end product comply with the required criteria – that means accessory parts such as buttons, zips, interlinings, hook-and-loop fasteners etc. in addition to the outer material and the sewing threads, or prints and coatings.
Since its introduction in 1992, the central focus of the STANDARD 100 by OEKO-TEX® has been the development of test criteria, limit values and test methods on a scientific basis. On the basis of its comprehensive and strict catalogue of measures, with several hundred regulated individual substances, the STANDARD 100 by OEKO-TEX® takes account of:
With its decades of experience, the OEKO-TEX® Standard 100 therefore contributes to high and effective product safety from a consumer’s point of view. Test criteria and limit values in many cases go far beyond applicable national and international standards. Extensive product checks and regular company audits also ensure that the industry has a globally sustainable awareness of the responsible use of chemicals. With this concept, the OEKO-TEX® Standard 100 has taken on a pioneering role for many years.
The criteria and limit values of the OEKO-TEX® tests for harmful substances according to STANDARD 100 are always based on the actual intended use of a textile item.
Here, the following principle applies: The more intensively a textile comes into contact with the skin (and the more sensitive the skin), the higher the human ecological requirements to be met.
Products with direct and/or intensive skin contact (e.g. baby articles, underwear, sports textiles, bed linen or terry towels) therefore have to meet more stringent requirements than garments worn away from the skin (e.g. jackets or coats) or furnishing materials (e.g. stores or table cloth).
Accordingly, successfully tested textile products are allocated to four different product classes:
Product class I :
Textiles and textile toys for babies and small children up to the age of three, e.g. underwear, romper suits, bed linen, bedding, soft toys etc.
Product class II :
Textiles which, when used as intended, have a large part of their surface in direct contact with the skin, e.g. underwear, bed linen, terry cloth items, shirts, blouses etc.
Product class III :
Textiles which, when used as intended, have no or only a little part of their surface in direct contact with the skin, e.g. jackets, coats, facing materials etc.
Product class IV :
Furnishing materials for decorative purposes such as table linen and curtains, but also textile wall and floor coverings etc.
The OEKO-TEX® test methodology is mainly based on the release of harmful substances from the materials to be tested. According to the opinion of the OEKO-TEX® Association, this is the most important concern for garments (possible contact with skin and risk of absorption through the skin). Strict methods are selected for the release of harmful substances.
Materials for babies and toddlers are additionally tested for colour fastness using a simulation of sucking /nibbling with a synthetic saliva and perspiration solution. Colourants must have a very high colour fastness level at this test.
Large-scale materials, which are encountered in the area of furnishing materials, are tested additionally for the emission of specific harmful substances into the air.
Odours that are atypical for the materials automatically lead to the exclusion of a certification for all articles
