Key result
Remarks on result:
no self-ignition observed up to the melting point

No endothermic or exothermic effect of the test item was observed between 20°C and 231°C (i.e. the melting temperature of the test item). It demonstrated that the test item is not self-ignitable. After the experiment, the test item had turned into a black charred residue and was collected in a container that was placed below the cube. It indicated that the test item had been molten, decomposed and/or reacted during the experiment.

Conclusions:
In the EC A.16 test no self-heating was observed up to the melting point of the test item. No relative self-ignition temperature could be determined.

Principles of method if other than guideline:
Modifications to the EU A.16 Method: A heating rate of 1.0-1.2 deg C/min or 0.6 deg C/min is used instead of 0.5 deg C/min due to an alternative Swiss Chemical Industry method and technical restriction of the apparatus used. Cylindric wire baskets with 0.2 mm openings are used.
GLP compliance:
not specified
Remarks on result:
no self-ignition observed up to the melting point

Heating rate: 1.2 deg C/min

The sample is heated from room temperature (about 20 deg C) to +/- 230 deg C (nearby the melting point). The sample shows no self-ignition to 400 deg C in the test run.

Conclusions:
In conclusion, the tested substance T000990 is not auto-flammable up to the temperature applied in the test run. The substance has no relative self-ignition temperature.

The Minium Ignition Temperature determined in the BAM oven is greater than 580°C.

Conclusions:
The Minimum Ignition Temperature determined in the BAM oven for T000990 is greater than 580°C.

Description of key information

The auto-flammability potential of T000990 was determined in a K1 GLP study (Brekelmans, 2016) carried out according to EC A.16. In the EC A.16 test no self-heating was observed up to the melting point of the test item. No relative self-ignition temperature could be determined.

Key value for chemical safety assessment

Additional information

There are two studies, for which the reliability was not assignable (K4), that report results supporting the results obtained in the key study of Brekelmans (2016). Both studies are performed by the Process Safety Center of Janssen Pharmaceutica. The first study reports no self-heating up to the melting point in an EC A.16 test (1996). The second study is an MIT dust cloud (BAM) study reporting no ignition of the dust cloud under the conditions of the test and concluding that the minimum ignition temperature of the dust cloud is > 580°C (1985).
