At an oven temperature of 230oC, an exothermic reaction of the test substance occurred. The maximum temperature during this reaction was determined to be 530 oC at an oven temperature of 265 oC. The test substance reached a temperature of 400 oC at an oven temperature of 245 oC -the self-ignition temperature. Temperatures during testing are shown in Table 1.
