The test item has an auto-ignition temperature of 235 °C according to the Regulation EC 440/2008 Method A.15. Auto-Ignition Temperature (Liquids and Gases).
It is note here that according to ECHA guidance –Guidance on information requirements and chemical safety assessment; chapter R.7A: Endpoint specific guidance, May 2008, the auto-ignition temperature for liquids are not used directly for classification and labeling according to regulation (EC) 1272/2008. However, they can be used in the chemical safety assessment in considering risks associated with processing the substance.
Nevertheless, according to DIN EN 13463-1 the test item has to be assigned to temperature class T3 (see the following Table).
Temperature classes
Temperature class | Maximum surface temperature / minimum auto ignition temperature [°C] |
T1 | 450 |
T2 | 300 |
T3 | 200 |
T4 | 135 |
T5 | 100 |
T6 | 85 |
