Key result
Remarks on result:
no self-ignition observed up to the melting point

No exothermal reaction of the test item was observed until a maximum temperature of 402 °C. An endothermic effect (melting) in the temperature range of 35 - 70 °C was observed.

Conclusions:
No self-ignition temperature was observed until the maximum temperature of 402 °C.
Executive summary:

A study according to Regulation (EC) No 440/2208, A.16 was performed to determine the relative self-ignition temperature of the test substance. 8 cm3 (8.1 g) of the test item was placed in an oven at 15 °C; the temperature/time curve relating to conditions in the centre of the sample is recorded while the temperature of the oven is increased to 400 °C at a rate of 0.5 °C/min. No exothermal reaction of the test item was observed until a maximum temperature of 402 °C. An endothermic effect (melting) in the temperature range of 35 - 70 °C was observed. Thus, the test item has no relative self-ignition temperature up to the melting point.

Description of key information

No self-ignition temperature was observed until the maximum temperature of 402 °C (reference 4.12 -1).
