- Conclusions:
- The test item has an auto-ignition temperature of 415 °C according to the Regulation EC No. 440/2008 Method A.15. Auto-Ignition Temperature (Liquids and Gases) and DIN 51794 (2003): Determination of Ignition Temperature.
- Executive summary:
The test item has an auto-ignition temperature of 415 °C according to the Regulation EC No. 440/2008 Method A.15. Auto-Ignition Temperature (Liquids and Gases) and DIN 51794 (2003): Determination of Ignition Temperature.
It is noted here that according to ECHA guidance – Guidance on information requirements and chemical safety assessment; chapter R.7A: Endpoint specific guidance, October 2015 – the auto-ignition temperature for liquids is not used directly for classification and labeling according to Regulation (EC) 1272/2008. However, it can be used in the chemical safety assessment in considering risks associated with processing the substance.
According to DIN EN 13463-1 the test item has to be assigned to temperature class T2 (see the following Table 3).

This study was GLP compliant and followedRegulation EC No. 440/2008 Method A.15. The study was given a reliability rating of 1 (reliable without restrictions).
Reference
An approximate value of the ignition temperature of the test item was first determined by a preliminary test. Table 1 gives the result of the preliminary test. An ignition is denoted as “+” and no ignition is denoted as “-“. 5 drops were put into the Erlenmeyer flask at each temperature.

Based on results of the main test series, the lowest auto-ignition temperature was 419 °C.
Regulation EC No. 440/2008 and DIN 51794:The auto-ignition temperature rounded down to the nearest multiple of 5 °C was determined as 415 °C.
For information:
DIN EN 14522:The auto-ignition temperature reduced by 1.5 % and rounded to the nearest integer temperature was determined as 413 °C.
Description of key information
The test item has an auto-ignition temperature of 415 °C according to the Regulation EC No. 440/2008 Method A.15. Auto-Ignition Temperature (Liquids and Gases) and DIN 51794 (2003): Determination of Ignition Temperature.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
