Link to relevant study record(s)
- Endpoint:
- auto-ignition temperature (liquids)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2016
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study without detailed documentation
- Qualifier:
- according to guideline
- Guideline:
- ASTM E659 (Standard test method for autoignition temperature of liquid chemicals)
- GLP compliance:
- not specified
- Key result
- Auto-ignition temperature:
- >= 420 - <= 425 °C
- Atm. press.:
- ca. 101 325 Pa
- Conclusions:
- Under the study conditions, the autoignition temperature of the test substance was determined to be between 420°C and 425°C (ASTM E-659).
- Executive summary:
A study was conducted to determine the autoignition temperature of the test substance according to the standard method - ASTM E-659. The method was abbreviated for this study to determine a range for the autoignition temperature of the test substance. The sample size was held constant (0.25mL/500cc) throughout the study. Varying the sample size could have lowered autoignition temperature a couple of degrees. The test was run to a ~5°C level of accuracy. Under the study conditions, the autoignition temperature of the test substance was determined to be between 420°C and 425°C (Boutreau, 2016).
