Referenceopen allclose all
The test substance showed an exothermic reaction starting at about 220 deg C. A maximum temperature of about 570 deg C was measured in the sample cube during the exothermic reaction. At the end of the measurement, the test substance was run out of the sample cube and only little red ash remained. T002102 shows a relative self-ignition temperature at about 306 deg C.
A small endothermic or exothermic effect of the test item was observed between 216°C and 232°C. A strong exothermic effect of the test item was observed between 238°C and 335°C. The temperature of the test item reached 400°C at an oven temperature of 300°C. It demonstrated that the self-ignition temperature of the test item is 300°C. After the experiment, the test item had turned into a charred residue. It indicated that the test item had been molten, decomposed and/or reacted during the experiment.
Description of key information
The auto-flammability potential of the substance was determined in a K1 GLP study performed according to EU Method A.16 (RCC Ltd., 2001). The substance was concluded to be auto-flammable under the conditions of the test and showed a relative self-ignition temperature at about 306°C.
To investigate if the substance is self-heating, the UN N.4 full-scale test was carried out in a K1 GLP study with the EC A.16 method as screening (Reingruber, 2016). The result of this screening is comparable to the result obtained by RCC Ltd. (2001): the self-ignition temperature was determined to be 300°C.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 306 °C
Additional information
The auto-flammability was determined by 2 tests according to the EU method A.16 and under GLP conditions and was therefore assigned as reliable without restrictions (Klimisch 1 score). During the first test (RCC Ltd., 2001), the substance showed an exothermic reaction starting at about 220 °C. A maximum temperature of about 570 °C was measured in the sample cube during the exothermic reaction. At the end of the measurement, the substance was run out of the sample cube and only little red ash remained. The substance shows a relative self-ignition temperature at about 306 °C.
During the second test (Reingruber, 2016), a strong exothermic effect of the test item was observed between 238°C and 335°C. The temperature of the test item reached 400°C at an oven temperature of 300°C. It demonstrated that the self-ignition temperature of the test item is 300°C. After the experiment, the test item had turned into a charred residue. It indicated that the test item had been molten, decomposed and/or reacted during the experiment.
