relative self-ignition temperature (solids)
Type of information:
experimental study
Adequacy of study:
key study
Study period:
16/03/16, 05/05/2016 and 24/05/2016
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
test procedure in accordance with generally accepted scientific standards and described in sufficient detail
according to guideline
EU Method A.16 (Relative Self-Ignition Temperature for Solids)
GLP compliance:
Other quality assurance:
other: ISO 9001-2008
TECNIO network
Key result
Relative self-ignition temperature:
600 °C
The relative self-ignition of the substance occurs at 600ºC
Executive summary:

A first DSC has been done and the sample has shown an endothermic phenomenon starting at 187ºC with an associated heat of 330.6 J/g

In view of these results, the same sample has been analysed by DSC-HP (in inert atmosphere, nitrogen) showing an exothermic phenomenon from 197°C with a peak at 208°C and an associated heat of 362.9 J/g which could be attributed to the thermal decomposition of the sample.

The sample sample has been by TGA showing a first weight loss of 7.9% from 30°C to 224°C, a second weight loss of 8.9% from 224°C to 278°C and a third weight loss of 32.5% from 280°C to 598°C.
