The label aims to reduce harmful substances. If a textile article carries the STANDARD 100 by OEKO-TEX label, every component of this article, i.e. every thread, button and other accessories, has been tested for harmful substances so that the article therefore is harmless for human health. Proof of this is provided by testing the end products for harmful chemicals.

OEKO-TEX® consist of 18 independent research and test institutes in Europe and Japan with testing laboratories in over 80 countries. They are responsible for the joint development of test methods and limit values which form the basis for the certifications.

The test is conducted by independent OEKO-TEX® partner institutes on the basis of an OEKO-TEX® criteria catalogue. In the test they take into account numerous regulated and non-regulated substances, which may be harmful to human health. In many cases, the limit values for the STANDARD 100 go beyond national and international requirements. The criteria catalogue is updated at least once a year and expanded with new scientific knowledge or statutory requirements.
