- Executive summary:
The auto-ignition temperature of the test material was assessed 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.
Under the conditions of the study, the auto-ignition temperature of the test material was 372.8°C at approximately 996.3 hPa.
Reference
In the preliminary test, an ignition was observed at 382°C.
Based on results of the main test series, the lowest auto-ignition temperature was 372.8°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 370°C.
DIN EN 14522: The auto-ignition temperature reduced by 1.5% and rounded to the nearest integer temperature was determined as 367°C.
The test material has an auto-ignition temperature of 372.8°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.
