Description of key information
Under the conditions of this study, the auto flammability temperature of the test material was determined to be 410 °C at 103.0 kPa.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 410 °C
Additional information
The auto flammability of the test material was investigated in a study which was performed in accordance with the standardised guideline EU Method A.15 under GLP conditions. The study was assigned a reliability score of 1 in accordance with the criteria for assessing data quality set forth by Klimisch et al. (1997).
A small, metered sample of the test material was inserted into a uniformly heated 500 mL glass flask containing air at a predetermined temperature. The contents of the flask were observed in a dark environment for 10 minutes following insertion of the sample, or until autoignition occurred. Autoignition was identified by the sudden appearance of a flame inside the flask and by a sharp rise in the temperature of the gas mixture. The lowest internal flask temperature at which the hot-flame ignition occurred for a series of prescribed sample volumes was taken to be the hot-flame autoignition (AIT) of the chemical in air at atmospheric pressure. Ignition delay times (ignition time lags) were measured in order to determine the ignition delay / ignition temperature relationship. The lowest temperature at which cool flames (CFT) were observed was also recorded. In all instances the ignition delay times were recorded.
A blue / orange flame was observed. No cool flames were observed.
Under the conditions of this study, the auto flammability temperature of the test material was determined to be 410 °C at 103.0 kPa.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
