Key result
Auto-ignition temperature:
333 °C
Atm. press.:
1 014.2 hPa

Detailed results:

Main test series Lowest temperature of ignition (°C) Highest temperature without ignition (°C) Atmospheric pressure (hPa)
1 341 337 1001.4-1001.5
2 337 333 998.4-998.9
3 333 330 998.5-1014.2
Conclusions:
The lowest auto-ignition temperature of the test item was found to be 333°C, rounded to 330°C, at 1014.2 hPa.
Executive summary:

The auto-ignition temperature of the test item was assessed according to EU Method A.15 for liquids and gases. First a preliminary test was performed. The lowest ignition temperature found in the preliminary test was 351°C. This temperature was used as a starting point for the main test. The lowest auto-ignition temperature observed in the main test was 333°C, which was rounded to the nearest multiple of 5°C as 330°C at a pressure of 1014.2 hPa.

Description of key information

For this endpoint, one study is available in which the auto-ignition temperature was determined according to EU Method A.15. The lowest auto-ignition temperature of the test item was found to be 333°C, rounded to 330°C, at 1014.2 hPa.
