Administrative data
Link to relevant study record(s)
- Endpoint:
- relative self-ignition temperature (solids)
- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- key study
- Study period:
- March 22, 1989
- Reliability:

- Justification for type of information:
- The read across approach has been detailed in the report attached to the IUCLID section 13.
- Reason / purpose for cross-reference:
- read-across source
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.16 (Relative Self-Ignition Temperature for Solids)
- GLP compliance:
- yes
- Relative self-ignition temperature:
- 260 °C
- Remarks on result:
- preliminary test
- Conclusions:
- Self-ignition temperature: 260 °C
- Executive summary:
The auto-fiammability of the test item was investigated in accordance with the prescriptions described into the EU Method A.16. The cube was filled with the test substance until the cube was completely full. The sample was suspended in the centre of the oven at room temperature. One thermocouple was placed at the centre of the cube and the other between the cube and the oven wall to record the oven temperature. The temperatures of the oven and sample were contineously recorded while the temperature of the oven was increased to 400 °C at a rate of 0.5 °C/min.
An exothermic reaction was determined at an oven temperature of 260 °C.
Conclusion
Self-ignition temperature: 260 °C
Reference
An exothermic reaction was determined at an oven temperature of 260 °C.
