Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
425 °C

Additional information

The autoignition temperature of the test material was determined in accordance with DIN 5194:2003 -05 (equivalent to EU Method A.15). Test material was intorduced in an open Erlenmeyer flask which was heated in an electric furnace; the temperature at which ignition occurred was recorded. Thereafter, remaining volatile fractions were removed from the flask by blowing with air. By varying the temperature and sample size the lowest value of a test series can be determined.

Under the conditions of the study, the autoignition temperature of the test material was determined to be 425 °C in a normal atmosphere.

The study was performed to standardised guidelines with a sufficient level of detail to assess the quality of the submitted data; it was assigned a reliability score of 1 according to the criteria of Klimisch (1997).
