3. 3.1.3.3In order to make use of all available data for purposes of classifying the hazards of the mixtures, certain assumptions have been made and are applied where appropriate in the tiered approach:
4. 3.1.3.4Classification of mixtures where acute toxicity data are available for the complete mixture
5. 3.1.3.5Classification of mixtures where acute toxicity data are available for the complete mixture: bridging principles
6. 3.1.3.6Classification of mixtures based on ingredients of the mixture (Additivity formula)
