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. The aim of the criteria catalogue is to level out global differences regarding the assessment of possible harmful substances in textiles. The OEKO-TEX® system can identify and eliminate potential sources of problematic substances in certified products. The OEKO-TEX® tests for harmful substances are fundamentally based on the respective purpose of the textiles and materials. The more intensive the skin contact of a product and the more sensitive the skin, the stricter the human ecological requirements that need to be complied with.
