Reference
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 31 Oct 2003
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- comparable to guideline study with acceptable restrictions
- Remarks:
- according to standard operating procedure of testing institute
- Reason / purpose for cross-reference:
- reference to same study
- Reason / purpose for cross-reference:
- reference to same study
- Principles of method if other than guideline:
- Differential thermal analysis (DTA)
- Type of method:
- differential scanning calorimetry
- Decomposition:
- yes
- Decomp. temp.:
- >= 310 °C
- Conclusions:

- relative self-ignition temperature (solids)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with national standard methods with acceptable restrictions
- Remarks:
- similar to Directive VDI 2263, part 1
- Reason / purpose for cross-reference:

- Qualifier:
- equivalent or similar to guideline
- Guideline:
- other: Directive VDI 2263, part 1
- Relative self-ignition temperature:
- >= 300 °C
- Conclusions:
- The test substance shows self-ignition at 300 °C. Therefore, the test material is not a self-heating substance according to Regulation (EC) 1272/2008
The neat sample and the sample with kieselguhr show self-ignition in the Grewer oven starting at 300 °C. A multi-stage reaction leading to a temperature of more than 600°C was recorded.
