1.2.1. Minimum classification
For certain hazard classes, including acute toxicity and STOT repeated exposure, the classification according to the criteria in Directive 67/548/EEC does not correspond directly to the classification in a hazard class and category under this Regulation. In these cases the classification in this Annex shall be considered as a minimum classification. This classification shall be applied if none of the following conditions are fulfilled:
Minimum classification for a category is indicated by the reference * in the column ‘Classification’ in Table 3.
The reference * can also be found in the column ‘Specific Conc. Limits and M-factors and Acute Toxicity Estimates (ATE)’ where it indicates that the entry concerned had specific concentration limits under Directive 67/548/EEC for acute toxicity. These concentration limits cannot be ‘translated’ into concentration limits under this Regulation, especially when a minimum classification is given. However, when the reference * is shown, the classification for acute toxicity for this entry may be of special concern.
