Test Guidance
ASTM E659
Method and material
A small metered sample of the product to be tested is inserted into a uniformly heated 500 mL glass flask containing air at a predetermined temperature. The contents of the flask are observed in a dark room for 10 mins following insertion of the sample, or until autoignition occurs. Autoignition is evidenced by the sudden appearence of a flame inside the flask and a sharp rise in the temperature of the gas mixture.
Result
The autoignition temperature is 381 °C at atmospheric pressure.
Reference
Description of key information

Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 381 °C
Additional information
The key study was performed in accordance with ASTM E659. A small metered sample of the product to be tested is inserted into a uniformly heated 500 mL glass flask containing air at a predetermined temperature. The contents of the flask are observed in a dark room for 10 mins following insertion of the sample, or until autoignition occurs. Autoignition is evidenced by the sudden appearence of a flame inside the flask and a sharp rise in the temperature of the gas mixture. The autoignition temperature is 381 °C at atmospheric pressure.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
