Results and discussion

Relative self-ignition temperature (solids)
Remarks on result:
other: not self ignitable

Any other information on results incl. tables

A small exothermic effect was observed starting at an oven temperature of 190°C. The temperature of the test substance reached maximum 205°C during this exothermic effect.


A relatively broad exothermic effect was observed starting at an oven temperature of 367°C. The temperature of the test substance reached 400°C at an oven temperature of 381°C and maximum 418°C during this exothermic effect. After the experiment, a small amount of charred residue was observed in the cube. It indicated that the test substance had decomposed and/or reacted during the experiment. Since the temperature rise was not steep, it was not considered to derive from self-ignition.

Applicant's summary and conclusion

The self-ignition temperature of the test substance was determined using a temperature programmed laboratory oven, a stainless steel wire mesh cube, NiCr/NiAl thermocouples and a temperature recording device.

Based on the results obtained the test substance is considered ‘not self-ignitable’.
