During the DSC run the test item showed an endothermic effect in the temperature range of 250 – 270 °C, which can be assigned to the start of the decomposition of the test item. No further thermal effects could be observed up to the maximum test temperature of 300 °C.

Conclusions:
In a test conducted according to OECD guideline 113 (1981) the thermal stability of the test item was determined using differential scanning calorimetry. The measurement was performed from room temperature to 300°C, at the temperature of 250°C to 270°C an endothermic peaks was detected which was considered to be the decomposition temperature. No further thermal effects could be observed up to the maximum test temperature of 300°C.
