Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Key result
Remarks on result:
no self ignition observed under the test conditions

No endothermic or exothermic effect of the test item was observed between 20°C and 400°C.  It demonstrated that the test item is not self-ignitable. After the experiment, the consistency of the sample was unchanged, i.e. no reaction and/or decomposition of the test item was observed.

Conclusions:
The test item is considered ‘not self-ignitable’.
Executive summary:

The self-ignition temperature of the test item was determined according to EU Method A.16, under GLP. The test cube was filled with test item and placed in the center of the oven. One thermocouple was placed at the center of the cube and the other between the cube and the wall of the oven wall to record the oven temperature. The oven was heated from 20°C to 400°C at a rate of 0.5°C/minute. The temperature of the oven at which the sample temperature reaches 400°C by self-heating is given as the self-ignition temperature. No endothermic or exothermic effect of the test item was observed between 20°C and 400°C.  It demonstrated that the test item is not self-ignitable. After the experiment, the consistency of the sample was unchanged, i.e. no reaction and/or decomposition of the test item was observed. Based on the results obtained the test item is considered ‘not self-ignitable’.

Description of key information

Key value for chemical safety assessment

Additional information

The self-ignition temperature of the test item was determined according to EU Method A.16, under GLP. A test cube filled with test item was placed in the center of an oven and heated from 20°C to 400°C at a rate of 0.5°C/minute. No endothermic or exothermic effect of the test item was observed between 20°C and 400°C. This demonstrated that the test item is not self-ignitable. After the experiment, the consistency of the sample was unchanged, i.e. no reaction and/or decomposition of the test item was observed. Based on the results obtained the test item is considered ‘not self-ignitable’.
