FAQs on Oeko-Tex Standard 100

The Oekotex Standard 100 was developed to give consumers confidence in the quality and safety of textiles. It ensures that textile products are tested for harmful substances and comply with certain limit values ​​for chemical substances.

No, the Oeko-Tex Standard 100 does not specifically refer to the organic quality of textiles. The certificate primarily focuses on the safety of textile products in relation to harmful substances. It sets limit values ​​for certain chemical substances and checks whether the products comply with these limit values.

The Oeko-Tex Standard 100 uses the concept of product classes to cover different types of textile products. Each product class has specific requirements and limits that apply to certification. Here are the Oeko-Tex Standard 100 product classes:

Product class I: This class includes textile products for babies and young children up to 36 months, such as clothing, bedding and toys. The requirements for this class are particularly strict, as the products have to meet the highest standards for skin compatibility and harmlessness.

Product class II: This class refers to textiles that have direct skin contact but are not intended for babies and small children. This can include adult clothing, underwear, bedding, and other textiles. The requirements for this class are also high and aim to protect the skin health of consumers.

Product class III: This class applies to textiles that do not come into direct contact with the skin, such as decorative fabrics and upholstery materials. The requirements for this class are slightly less stringent as there is less chance of direct skin contact.

Product class IV: This class is specific to home textiles and includes, for example, bed linen, curtains and towels. The requirements for this class relate to harmlessness during use and are intended to ensure that the textiles do not emit any harmful substances.

The Oeko-Tex Standard 100 product classes allow manufacturers to certify their textile products appropriately depending on their intended use and potential exposure to the skin. In this way, consumers can be sure that the certified textiles meet the specific requirements for their intended use.

The Oeko-Tex seal is awarded by independent certification bodies accredited by the International Association of Research Institutes for Textiles and Clothing (Oeko-Tex). These certification bodies carry out audits and tests to ensure that the textile products meet the requirements of the Oeko-Tex Standard 100.
