8.9.4 If data are available to enable the characterization of the mixture as a mixture that causes specific target organ toxicity arising from repeated exposure, in accordance with the bridging principles referred to in subsections 2.3(3) to (8), the mixture must be classified in a category of this hazard class in accordance with those subsections.
Marginal note:Data available for ingredients
8.9.5 A mixture that contains one or more ingredients that are classified as a substance that causes specific target organ toxicity arising from repeated exposure is classified as follows:
(a) in the category “Specific Target Organ Toxicity — Repeated Exposure — Category 1”, if it contains at least one ingredient at a concentration equal to or greater than the concentration limit of 1.0% that is classified in the category “Specific Target Organ Toxicity — Repeated Exposure — Category 1”; or
(b) in the category “Specific Target Organ Toxicity — Repeated Exposure — Category 2”, if it contains at least one ingredient at a concentration equal to or greater than the concentration limit of 1.0% that is classified in the category “Specific Target Organ Toxicity — Repeated Exposure — Category 2”.
