Referenceopen allclose all
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.
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.
The Minium Ignition Temperature determined in the BAM oven 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).
