No endothermic or exothermic effect of the test substance was observed between 19°C and 64 – 67 °C (i.e. the melting temperature range of the test substance). It demonstrated that the test substance is not self-ignitable. Above the melting temperature range, three exothermic effects of the remaining test substance by self-heating were observed. The first two effects were observed at oven temperatures of 128 °C and 170 °C with test substance temperatures of 150 °C and 227 °C, respectively. The third effect was observed at an oven temperature of 355°C. During this effect the remaining test substance reached a temperature of 400°C. These exothermic effects are probably due to subsequent decomposition and are of no relevance for the self-ignition study.
