The tests for harmful substances according to OEKO-TEX® Standard 100 are always based on the intended use of the textile. The following principle therefore 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.
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.
