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

The self-ignition temperature, as obtained by this method, is the minimum ambient temperature expressed in °C at which a certain volume of a substance will ignite under defined conditions.

If an exothermic reaction of the test substance appears, the sample thermocouple shows a sharp temperature rise above the oven temperature. The temperature of the oven at which the sample reaches 400°C by self-heating is appointed as the self-ignition temperature of the test substance.

The temperature recording of the oven and sample during the experiment are shown in the table below.

No endothermic or exothermic reaction was observed during the performance of the test, thus BMH is not self-ignitable.

The test substance had melted and changed into a black residue.

Conclusions:
According to the criteria as described in the method A.16 of Directive 92/69/EEC, BMH is not self-ignitable.

Description of key information

BMH is not self-ignitable (EC A.16)

Key value for chemical safety assessment

Additional information

The self-ignition temperature of the substance has been determined according to Directive 92/69/EEC, A.16 (EEC publ no. L383, Dec 1992). No self-ignition up to 400°C. No endothermic or exothermic reaction up to 400°C.
