Link to relevant study record(s)
- Endpoint:
- relative self-ignition temperature (solids)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:
- Guideline study (EU method A.16).
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.16 (Relative Self-Ignition Temperature for Solids)
- Deviations:
- no
- GLP compliance:
- no
- Remarks on result:
- other: The test substance WO2 (tungsten dioxide) revealed no self-ignition at temperatures up to 400 ºC.
- Conclusions:
- The test substance WO2 (tungsten dioxide) revealed no self-ignition at temperatures up to 400 ºC.
- Executive summary:
A test according to guideline EU A.16 was conducted to determine the self-ignition temperature of tungsten dioxide (WO2; > 99.8 % purity). The test substance WO2 revealed no self-ignition at temperatures up to 400 ºC.
Reference
The temperature of the oven and sample were continuously recorded while the temperature of the oven was increased to 400 ºC at a rate of 0.5 ºC/min. No self-ignition occored, since the sample thermocouple showed no very sharp temperature rise above the oven temperature.
Description of key information
In a test conducted according to EU method A.16 the test substance WO2 revealed no self-ignition at temperatures up to 400 ºC. WO2 cannot be considered auto flammable.
Key value for chemical safety assessment
Additional information
Tungsten dioxide (WO2) is reported to be not auto-flammable in the safety data sheet.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
