Administrative data
Link to relevant study record(s)
- Endpoint:
- relative self-ignition temperature (solids)
- Type of information:
- other: Company data
- Adequacy of study:
- key study
- Study period:
- Not specified
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- study well documented, meets generally accepted scientific principles, acceptable for assessment
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.16 (Relative Self-Ignition Temperature for Solids)
- Deviations:
- no
- GLP compliance:
- no
- Key result
- Relative self-ignition temperature:
- 400 °C
- Conclusions:
- Under the conditions of this test the minimum ignition temperature of the dust air cloud corresponds to 400 °C. In the dynamic Grewer test no auto-ignition temperature could be determined up to 360 °C. Melting of the sample starting at approximately 210 °C.
- Executive summary:
The auto ignition temperature of the test material was investigated in accordance with the standardised guideline EU Method A.16.
3.33 g of the test material was used in a dynamic test with 1.2 °C/min heating from 20 up to 360 °C with 2 L/min air flow.
99 % of weight was lost after the test, no test material remains were in the basket.
Under the conditions of this test the minimum ignition temperature of the dust air cloud corresponds to 400 °C. In the dynamic Grewer test no auto-ignition temperature could be determined up to 360 °C. Melting of the sample starting at approximately 210 °C.
Reference
- Auto ignition temperature (A16): 400 °C
- Loss of weight after test: 99 %
- No material remains in the basket after the test
