Link to relevant study record(s)
- Endpoint:
- relative self-ignition temperature (solids)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 26 February 2018 - TBC
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:

- Qualifier:
- according to guideline
- Guideline:
- EU Method A.16 (Relative Self-Ignition Temperature for Solids)
- Version / remarks:
- Regulation (EC) 440/2008 of 30 May 2008
- Deviations:
- no
- GLP compliance:

- Key result
- Relative self-ignition temperature:
- 210 °C
- Conclusions:
- The relative self-ignition temperature of the test item was determined to be 210 °C under prescribed test conditions.
- Executive summary:
EU Method A.16. – The relative self-ignition temperature of the test item was determined using a procedure designed to be compatible with Method A.16., Relative Self-Ignition Temperature for Solids, of Commission Regulation (EC) No 440/2008 of 30 May 2008.
An aliquot of test item (8 cm3) was packed into a suitable vessel and placed in an oven as prescribed by the guideline. The temperature of the oven was increased from ambient to 400 ℃ at a constant heating rate of 0.5 K/min. The temperature and behaviour of the test item monitored throughout this thermal programme.
During the test an exothermic effect was detected, the relative self-ignition temperature of the test item was determined to be 210 °C under prescribed test conditions.
Reference
Results:
During the investigation of the self-ignition temperature of the test item an exothermic effect was detected. The temperature at which the oven at which the sample temperature reaches 400 °C by self-heating is 210 °C.
In accordance with Method A.16 of Regulation EC No. 440/2008 (as amended) the self-ignition temperature of the test item is determined to be 210 °C.
