Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

A negative result was obtained. No spontaneous ignition occurred and no significant exothermic effect of the test item was observed. It demonstrated that the test item is “not a self-heating substance”. According to the UN guideline, no further testing is required.

After the experiment, the test item had turned into a dark orange brown expanded hard solid residue. It indicated that the test item had been molten, decomposed and/or reacted during the experiment.

Conclusions:
No spontaneous ignition occurred and no significant exothermic effect of the test item was observed at 140°C in a UN Test N.4 “Test Method for Self-heating Substances”.
Executive summary:

No spontaneous ignition occurred and no significant exothermic effect of the test item was observed at 140°C in a UN Test N.4 “Test Method for Self-heating Substances”.

Description of key information
