The OECD Guidelines are a unique tool for assessing the potential effects of chemicals on human health and the environment. Accepted internationally as standard methods for safety testing, the Guidelines are used by professionals in industry, academia and government involved in the testing and assessment of chemicals (industrial chemicals, pesticides, cosmetics, etc.). These Guidelines are regularly updated with the assistance of hundreds of national experts from OECD member countries.
Information on the Mutual Acceptance of Data (MAD) system, the full list of adopted Test Guidelines, the draft TGs under public commenting rounds, the draft Guidance and review documents are available on the Test Guidelines Programme.
This Series includes publications related to testing and assessment of chemicals; some of them support the development of OECD Test Guidelines (e.g. validation reports, guidance documents, detailed review papers).
The Test Guidelines that have been deleted should not be used for new testing. They are included here because it may be useful to consult them in the framework of the assessment of substances based on old study reports. The guaranties of Mutual Acceptance of Data (MAD) would not apply if these Test Guidelines were used for new testing.
In November 2012, the Joint Meeting of the Chemicals Committee and Working Party on Chemicals, Pesticides and Biotechnology decided on a transition period of 18 months, between the Council Decision and the effective deletion, for Test Guidelines that have been updated or deleted.
