Description
Annex X part A to the Proposal for a Regulation concerning the Registration, Evaluation, Authorisation and Restrictions of Chemicals (REACH) The Annex sets out test methods for the determination of physicochemical, toxicological and ecotoxicological properties listed in Annexes A-D to this Regulation. The methods are based on those recognised and recommended by competent international bodies (in particular OECD). When such methods were not available, national standards or scientific consensus methods have been adopted. Generally, tests should be performed with the substance as defined by the Regulation. Attention should be given to the possible influence of impurities on the test results. When the methods of this Annex are inappropriate for the investigation of a certain property, the notifier must justify the alternate method used.
