These obsolete Test Guidelines have been deleted in order to allow national/regional regulations that make reference to specific Test Guidelines and versions to be updated accordingly. They 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.
