Description of key information

Based on a review of the substance’s chemical structure and test data (on flash point and boiling point) the substance is not considered to be a flammable liquid.

Key value for chemical safety assessment

non flammable

Additional information

According to the Endpoint Specific Guidance R.7a, the primary value used to assess the ease of ignition for liquids and low melting point solids is the flash point. As 4-chloro-o-xylene is a liquid, the flash point data is considered to be more appropriate than the flammability test for solid substances. It is therefore considered to be justified to omit the flammability test required under point 7.10 of Annex VII.

In accordance with point 1 of Annex XI, it is considered justified to omit the testing for pyrophoric properties and testing for substances or mixtures which in contact with water emit flammable gases. Testing does not appear scientifically necessary as experience in use and experience of handling the substance indicates that it does not possess pyrophoric properties or emit flammable gases in contact with water.

Justification for classification or non-classification

In accordance with the criteria for classification as defined in Annex I, Regulation (EC) No 1272/2008, the substance does not require classification with respect to flammability.
