According to DIN EN 13463 -1 the test item has to be assigned to temperature class 2 according to DIN EN 13463 -1. The auto-ignition temperature for liquids is not directly used for classification and labelling according to regulation (EC) 1272/2008, but can be used in the chemical safety assessment in considering risks associated with processing the substance. (ECHA Guidance on information requirements and chemical assessment , chapter R7A: endpoint specific guidance, May 208)
