Administrative data
Link to relevant study record(s)
- Endpoint:
- relative self-ignition temperature (solids)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 03/02/2016 and 11/03/2016
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with generally accepted scientific standards and described in sufficient detail
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.16 (Relative Self-Ignition Temperature for Solids)
- GLP compliance:
- no
- Other quality assurance:
- other: ISO 9001-2008
- Remarks:
- TECNIO network
- Key result
- Relative self-ignition temperature:
- 472 °C
- Conclusions:
- The relative self-ignition of the substance occurs at 472ºC
- Executive summary:
A first DSC has been done and the sample has shown a first wide endothermic phenomenon starting at 49ºC with an associated heat of 120.8 J/g and a second endothermic phenomenon starting at 195ºC with an associated heat of 26.8 J/g. Next, an exothermic phenomenon is observed starting at 282ºC with an associated heat of 481 J/g and another exothemic phenomenon is observed starting at 472ºC with an associated heat higher than 1116.9 J/g.
In view of these resultst, the same sample has been analysed by DSC-HP (in inert atmosphere, nitrogen) and has showed an exothermic phenomenon starting at 278ºC with a peak at 289ºC and an associated heat of 477 J/g which could be attributed to the thermal decomposition of the substance.
