Division 4.1.3.1 F1

The classification system for mixtures covers all classification categories which are used for substances, i.e. categories Acute 1 and Chronic 1 to 4. In order to make use of all available data for purposes of classifying the aquatic environmental hazards of the mixture, the following is applied where appropriate:

The ‘ relevant components ’ of a mixture are those which are classified ‘ Acute 1 ’ or ‘ Chronic 1 ’ and present in a concentration of 0,1 % (w/w) or greater, and those which are classified ‘ Chronic 2 ’ , ‘ Chronic 3 ’ or ‘ Chronic 4 ’ and present in a concentration of 1 % (w/w) or greater, unless there is a presumption (such as in the case of highly toxic components (see section 4.1.3.5.5.5)) that a component present in a lower concentration can still be relevant for classifying the mixture for aquatic environmental hazards. Generally, for substances classified as ‘ Acute 1 ’ or ‘ Chronic 1 ’ the concentration to be taken into account is (0,1/M) %. (For explanation M-factor see section 4.1.3.5.5.5.)
