Reference
Preliminary Test
An approximate value of the ignition temperature of the test item was first determined by a preliminary test. In the preliminary test, the lowest temperature at which an ignition occurred was 352 °C.
Main Test
Based on results of the main test series, the lowest auto-ignition temperature was 350 °C.
Regulation EC No. 440/2008 and DIN 51794: The auto-ignition temperature rounded down to the nearest multiple of 5 °C was determined as 345 °C.
For information:
DIN EN 14522: The auto-ignition temperature reduced by 1.5 % and rounded to the nearest integer temperature was determined as 344 °C.
Description of key information
auto-ignition temperature (determined using EU Method A.15 / DIN 51794 (2003); GLP): 345 °C
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 345 °C
Additional information
The auto-ignition temperature of the test material was determined using EU Method A.15 / DIN 51794 (2003).
A reliability score of 1 was assigned, in accordance with the criteria for assigning data quality in line with the principles described by Klimisch (1997).
According to DIN EN 13463-1 the test item has to be assigned to temperature class T2.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
