- Atm. press.:
- >= 1 005.2 - <= 1 005.8 hPa
- Conclusions:
- Under the conditions of the test the autoignition temperature of the test material was 366.5°C at 1005.2 – 1005.8 hPa.
- 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 test the auto-ignition temperature of the test material was 366.5°C at 1005.2 – 1005.8 hPa.
Reference
In the preliminary test, an ignition was observed at 469°C.
Based on results of the main test series, the lowest auto-ignition temperature was 366.5°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 365°C.
For information:
DIN EN 14522: The auto-ignition temperature reduced by 1.5% and rounded to the nearest integer temperature was determined as 361°C.
The test material has an auto-ignition temperature of 366.5°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.
