Oeko-Tex Standard 100 or Öko-Tex Standard 100 is an international testing and certification system for textiles, limiting the use of certain chemicals, developed in 1992.
The test criteria and the related test methods are standardized on an international level and are widely included as guidance in terms and conditions of purchase and delivery right through to the retail sector. With a total of over 51,000 certificates issued for millions of different individual products, and over 6,500 companies involved worldwide, the Oeko-Tex Standard 100 has become the best known and most successful label for textiles tested for harmful substances.
The following Oeko-Tex product classes differ generally in the requirements that the products have to fulfill and by the test methods applied.
I = products for babies (up to age of 36 months with the exception of leather clothing)
II = products with direct contact to skin (blouses, shirts, underwear, etc.)
III = products without direct contact to skin (stuffing, coat, etc.)
IV = decoration material (table cloths, wall coverings, furnishing fabrics and curtains, upholstery fabrics and floor coverings, etc.)
The greater the contact with the skin, the more stringent the requirements is.
