N-Class reference removed

N-Class was a database developed by the Nordic Council of Ministers in collaboration with the European Chemicals Bureau (ECB). The database contained substances discussed in the Commission's Working Group on the Classification and Labelling of Dangerous Substances.

The database described fire, health and environmental hazard classifications for substances listed in Annex 1 to Council Directive 67/548 / EEC on the classification and labelling of dangerous substances. In addition, there are substance specific data that formed the basis of the assessment made by the Commission's working groups. These data primarily concern environmental effects. The database is no longer in use, and the substances in PRIO that previously only had a reference to N-Class have been reviewed and updated with a reference to the CLP Regulation.
