Room temperature: 21 - 26°C
Atmospheric pressure: 101.88 – 102.05 kPa
The auto-ignition temperature of the substance has been determined to be 228 ± 5°C
Description of key information
Auto-ignition temperature: 228 ±5°C at 101.88-102.05 kPa (EU Method A.15)
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 228 °C
Additional information
Four reliable measured auto-ignition temperature studies are available for the submission substance. An auto-ignition temperature value of 228±5°C at 101.88-102.05 kPa was determined for the substance using an appropriate test method in accordance with EU Method A.15 and in compliance with GLP. The result is considered to be reliable and is selected as key study.
In available supporting studies, the substance has measured auto-ignition temperature values of 230°C, 235°C at 955 hPa and 260°C at 722-723 mmHg were determined for the substance in accordance with DIN 51794 Test Method and in compliance with GLP. The key study was selected as the study with the lowest auto-ignition temperature result, which is a conservative approach. The supporting studies are in good agreement with the key study.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
