Evaluation of Data:

The auto-ignition temperature is the lowest temperature that will result in the ignition of the test item after being dropped into the test flask.

The room temperature and atmospheric pressure is recorded for each day of the test.

*A second measurement at 402 °C (0.8 g) was performed in error as no replicate was required. This demonstrated a blue/orange flame which was inconsistent with the first measurement at 402 °C (0.8 g) and a further measurement at 402 °C (1.0 g); both of which demonstrated no ignition. This result was therefore considered to be anomalous.  

 

 

Room temperature: 18 to 19 °C

Atmospheric pressure: 99.7 to 100.8 kPa

Conclusions:
The test item has been determined to have an auto-ignition temperature of 404 ± 5 °C.
Executive summary:

EU Method A.15. – The auto-ignition temperature of the test item was determined using a procedure designed to be compatible with Method A.15., Auto-Ignition Temperature (Liquids and Gases), of Commission Regulation (EC) No 440/2008 of 30 May 2008.  Due to the test item having a measured melting point range of 59.2 - 81.0 C (EU Method A.1.; R Butler (2018)), the liquid protocol was selected in place of the solid protocol.

Aliquots of test item (0.2 – 1.0 g) were dropped into a heated flask which was observed for signs of ignition over a 300 second period.  This procedure was repeated, varying the sample size, as necessary, until the lowest temperature at which ignition, if any, occurred within 300 seconds of insertion, was determined.

The test item has been determined to have an auto-ignition temperature of 404 ± 5 °C.
