- 314 °C
- Remarks on result:
- other: Atmospheric pressure not specified
- Conclusions:
- Under the conditions of this study the autoignition temperature of the test material was determined to be 314 °C.
- Executive summary:
The auto-ignition temperature of the test material was determined in accordance with the standardised guideline DIN 51794, using the Petrotest ZPA 3 with automated Test Programs.
The measurements were performed with heating from 25°C up to a maximum of 650°C. The range-finder program heated at 5 K/min to determine an approximate temperature in 20 K steps. Program A then determined the minimal auto-ignition temperature in 5 K steps followed by Program B which determined the minimal auto-ignition temperature in 2 K steps.
Under the conditions of this study the auto-ignition temperature of the test material was determined to be 314°C.

Value form measurement device:
Tu = 319°C
Tc = Tu x 0.985 = 314°C
Tu - uncorrected flashpoint from measurement
Tc - corrected flashpoint (rounded to next digit)
In the preliminary test, an ignition was observed at 380°C.
Based on results of the main test series, the lowest auto-ignition temperature was 355.1°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 355°C.
For information:
DIN EN 14522: The auto-ignition temperature reduced by 1.5% and rounded to the nearest integer temperature was determined as 350°C.
The test material has an auto-ignition temperature of 355.1°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.

The auto-ignition temperature of the test material was determined in accordance with the standardised guideline DIN 51794, using the Petrotest ZPA 3 with automated Test Programs. The study was awarded a reliability score of 2 in accordance with the criteria set forth by Klimisch et al. (1997).
The measurements were performed with heating from 25°C up to a maximum of 650°C. The range-finder program heated at 5 K/min to determine an approximate temperature in 20 K steps. Program A then determined the minimal auto-ignition temperature in 5 K steps followed by Program B which determined the minimal auto-ignition temperature in 2 K steps.
