Description of key information
The auto-ignition temperature is experimentally measured to be 407 °C.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 407 °C
Additional information
The auto-ignition temperature is experimentally measured to be 407 °C. This conclusion is supported by the Petroleum Labs, Inc. measured initial boiling point of 407 °C and the Kobayashi, S. and Saegusa, T. reference value of 490 °C. Additionally, a value of 407 °C agrees with manufacturing experience.
The Zedi US Inc. study is disregarded. Values reported disagree with experience during manufacturing and use. Also, the value disagrees with secondary reference values and the subsequent re-testing of the material.
