Remarks:

at atmospherical pressure

At an oven temperature of approximately 265 °C, a minor endothennal effect was observed. The sample temperature increased to approximately 335 °C. According to the criteria laid down in the EC Directive, this is not considered to be self ignition, because the peak temperature did not attain the level of 400 °C.

The black sample residue recovered after the test weighed 2.22 grams.

Conclusions:

The test substance has no relative self-ignition temperature in the sense of ECTest Guideline A.16. It should however be noted that minor endothermal effects could occur.
