Oeko tex standard 100

July 22, 2014

Oeko-Tex Standard 100 or Öko-Tex Standard 100 (sometime misspelled Oktex) is an independent testing and certification system for textile products from all stages of production (fibres, yarns, fabrics, ready-to-use end products, including accessories) along the textile value chain.

The label ‘Confidence in Textiles’ of the product-related Oeko-Tex Standard 100 (textiles tested for harmful substances) is supplemented by the certification of environmentally friendly production facilities according to Oeko-Tex Standard 1000 and by the product label Oeko-Tex Standard 100plus for products tested for harmful substances from environmentally friendly production.

It was developed in 1992.


The global standard is issued by the International Association for Research and Testing in the Field of Textile Ecology (Oeko-Tex) with headquarters in Zurich (Switzerland). It currently includes 15 neutral test and research institutes in Europe and Japan with contact offices in over 60 countries around the world. The internationally standardised criteria catalogue for testing for harmful substances is regularly modified and expanded.

Oeko-Tex Standard 100


The OEKO-TEX® Standard 100 is an independent testing and certification system for textile raw materials, intermediate and end products at all stages of production. Examples for items eligible for certification: Raw and dyed/finished yarns, raw and dyed/finished fabrics and knits, ready-made articles (all types of clothing, domestic and household textiles, bed linen, terry cloth items, textile toys and more).


Testing for harmful substances includes:

illegal substances legally regulated substances known harmful (but not legally regulated) chemicals as well as parameters for health care. In their entirety the requirements clearly exceed existing national legislation.

Laboratory tests and product classes

OEKO-TEX® testing for harmful substances always focus on the actual use of the textile. The more intensive the skin contact of a product, the stricter the human ecological requirements to be met.

Accordingly there are four product classes:

Product class I: Textile items for babies and toddlers up to 3 years (clothing, toys, bed linen, terry cloth items etc.) Product class II: Textiles used close to the skin (underwear, bed linen, T-shirts etc.) Product class III: Textiles used away from the skin (jackets, coats etc.) Product class IV: Furnishing materials (curtains, table cloths, upholstery materials etc.) Certification

The requirement for certification of textile products according to OEKO-TEX® Standard 100 is that all components of an item have to comply with the required criteria without exception – that means in addition to the outer material also sewing threads, linings, prints etc. as well as non-textile accessories such as buttons, zip fasteners, rivets etc.


Oeko-Tex Standard 100 was introduced by the Hohenstein Institute and the Institute for Ecology, Technology and Innovation ÖTI (Vienna/Austria) in 1992. The aim was to make textile products from conventional production having undergone laboratory testing for harmful substances obvious to consumers by using a label (‘Confidence in Textiles’). Textiles with this label are proven to remain below the set limit values for certain harmful substances.

At the same time the introduction of the standard established a globally standardised quality assurance system for manufacturers and retailers to take into account the decreasing vertical range of manufacture in the individual facilities of the textile and clothing industry and to compensate for regionally different evaluation standards for the risk potential of harmful substances. Use of the Oeko-Tex certificate therefore documents compliance with human ecology quality towards subsequent production levels and end consumers.


Textile products can only be certified according to Oeko-Tex Standard 100 if all components comply with the required criteria – for an item of clothing this could be in addition to the outer fabric e.g. threads, prints, buttons/zips/studs or any other accessory parts. Extent and requirements of Oeko-Tex testing for harmful substances depend on the intended use of a textile product – the more intensive the skin contact, the stricter the limit values that may not be exceeded. There are four product categories: 1. I – Items for babies and infants (up to 36 months of age) 2. II – Items with direct prolonged or large-area skin contact 3. III – Textiles without or with little skin contact 4. IV – Furnishing materials (for decoration purposes)

After successful laboratory testing and signing of a declaration of conformity the manufacturer receives the Oeko-Tex certificate for their product which is valid for one year. After a repeat test, existing certificates can be extended for a period of one year in each case.

Test criteria

The test criteria and limit values on which Oeko-Tex testing for harmful substances is based are globally binding and are modified and expanded each year. The test parameters include: 1. substances banned by law 2. substances regulated by law 3. substances known to be harmful to health which have not yet been explicitly regulated by law 4. parameters for safeguarding health

Textile products are tested for e.g. formaldehyde, pesticides, extractable heavy metals, organochloride carriers as well as preservatives such as tetra andpentachlorophenol. The textiles are also checked for (legally banned) carcinogenic MAK amines from special azo dyes as well as for dyestuffs which have scientifically proven allergenic potential. Furthermore all tested items must have a skin-friendly pH value and good colour fastness. The current revision of the test criteria is available at the official website.[1]

Control tests

To verify compliance with the required limit values the Oeko-Tex Association carry out annual product checks to the extent of at least 15% of all issued Oeko-Tex certificates.

The control tests include

  1. verification of provided documents
  2. laboratory tests on provided sample materials
  3. laboratory tests on items with Oeko-Tex label which are available in stores
  4. laboratory tests on random product samples which are taken unannounced from certified companies

In addition to this, independent auditors check the production conditions in certified companies during site visits.

Prevalence and awareness

Oeko-Tex Standard 100 is the product label for textiles tested for harmful substances with the largest prevalence worldwide. More than 8,500 manufacturers in over 80 countries currently participate in Oeko-Tex certification (as of 12/2009). To date the Oeko-Tex Association has issued over 100,000 certificates for textile products from all stages of production (as of 12/2009).

According to a consumer survey by GfK in 2006, the label ‘Confidence in Textiles’ has a supported customer awareness level of over 46% in Germany. A consumer survey by BBE Retail Experts carried out in seven European countries (Austria, Switzerland, France, Italy, Spain, Portugal, Netherlands) in 2008 found an average awareness level of 42% for the Oeko-Tex label.

Oeko-Tex Standard 1000

As a supplement to product certification according to Oeko-Tex Standard 100, the Oeko-Tex Standard 1000, which was introduced in 1995, is a certification system for environmentally friendly production sites in the textile and clothing industry. The aim is to test and certify the production conditions at a certain textile production site. Verification is carried out by independent auditors from one of the 14 member institutes of ‘Oeko-Tex International – Association for the Assessment of Environmentally Friendly Textiles’. The certificate is valid for three years and has to be renewed regularly.


The guiding principle of certification according to Oeko-Tex Standard 1000 is not a one-off optimisation of environmental measures but rather the permanent improvement of overall environmental performance within a company.


The precondition for certification of a production facility is also the introduction of an environmental management system where already existing systems such as ISO 14001 or EMAS can be fully taken into account for certification according to Oeko-Tex Standard 1000.

Test criteria

The test criteria of Oeko-Tex Standard 1000 include, among others:

  1. exclusion of environmentally harmful technologies, chemicals and auxiliary materials (e.g. ban of chlorine bleach)
  2. compliance with guide values for waste water and exhaust air treatment
  3. economical use of energy resources
  4. avoidance of noise and dust pollution

In addition to this the standard stipulates compliance with social criteria such as certain minimum requirements for workplace safety, ban on child labour/discrimination/forced labour or adequate working times/holidays/wages.

Oeko-Tex Standard 100plus

If a company meets the requirements of Oeko-Tex Standard 1000, i.e. there is an audited environmentally friendly production facility and the products have been successfully tested for harmful substances according to Oeko-Tex Standard 100, then these products can be labelled with the Oeko-Tex Standard 100plus. This then means that they were tested for harmful substances and produced in an environmentally friendly and socially acceptable manner. Another precondition for this is, however, that the entire production chain – i.e. all production facilities involved in the manufacturing of a product – are certified as environmentally friendly according to Oeko-Tex Standard 1000.
