- other: The value was obtained with a sample volume of 1 ml in a 200 ml glass vessel and was rounded off to the nearest multiple of 5°C.
- Conclusions:
- A self-ignition temperature of 235°C at 1014.0 – 1022.5 hPa was determined in a reliable study conducted according to an appropriate test protocol, and in compliance with GLP.
Reference
The estimated auto-ignition temperature in the preliminary study was 250°C.
The results of the main study on the determination of the auto-ignition temperature of the test
substance are given in Table 1.
It was observed that the auto-ignition temperature of the test substance decreased with
increasing the sample volume. At a volume of 1 ml in a 200 ml glass vessel an auto-ignition
temperature of 238°C was observed. The volume was considered to be the maximum
representative volume of the test and the therefore the temperature obtained at this volume was
rounded off to the nearest multiple of 5°C giving the auto-ignition temperature of the test
substance (i.e. 235°C). No further testing was performed.

Description of key information
Auto flammability: 235°C at 1014.0 – 1022.5 hPa (EU Method A.15)
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 235 °C
Additional information
A measured auto-ignition temperature of 235°C at 1014.0 – 1022.5 hPa was determined for the substance in accordance with EU Method A.15 and in compliance with GLP. The result is considered to be reliable.
