It was developed in 1992. Responsibility for the Oeko-Tex kanon 100 is shared between the 17 test institutes which make up the International Oeko-Tex Association, which has branch offices in more than 40 countries worldwide. The criteria catalogue which forms the basis for the tests for harmful substances is based on the latest scientific findings and is continually updated; the human ecological safety of the textiles tested are more far-reaching every year. 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 kanon 100 has become the best known and most successful label for textiles tested for harmful substances.
