Flash point
Administrative data
Link to relevant study record(s)
- Endpoint:
- flash point of flammable liquids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2004-11-29 to 2004-12-10
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.9 (Flash-Point)
- Version / remarks:
- 1992
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- ASTM D93 (Standard test methods for flash point by pensky-martens closed cup tester)
- Deviations:
- no
- GLP compliance:
- yes
- Type of method:
- closed cup
- Flash point apparatus:
- Pensky-Martens apparatus
- Dynamic viscosity of test material:
- 1.34 mPa*s at 25°C (predicted, US EPA T.E.S.T. v. 4.2; consensus model). The consensus model is based on the outcome of 5 different models (average), resulting in a range between 0.91 mPa*s and 2.04 mPa*s.
- Key result
- Flash point:
- 71.9 °C
- Atm. press.:
- 1 013 hPa
- Interpretation of results:
- Category 4 (combustible liquids) based on GHS criteria
- Conclusions:
- Flash point (EU-method A.9): 71.9 °C at 1013 hPa
- Executive summary:
The flash point for 1-chloro-2,3-dimethylbenzene was determined according to EU method A.9 and ASTM D 93 (Pensky-Martens Closed Cup) compliant with GLP.
The method was validated with reference substance n-decane:
The average (n = 2) observed flash-point of n-decane was 52.3 ± 0.2 °C, adjusted to 101.3 kPa, which was not significantly different from the reported (ASTM D 93) value of 53 ± 2 °C,
indicating acceptable method performance.
For the test Substance, the average (n = 2) observed flash-point was 71.9 ± 0.2 °C, adjusted to 101.3 kPa.
Reference
Reference Substance: The average (n = 2) flash-point of the Reference Substance n-decane was 52.3 ± 0.2 °C, adjusted to 101.3 kPa. This flash-point was not significantly different from the reported (ASTM D 93) value of 53 ± 2 °C, indicating acceptable method accuracy.
Test Substance: The average (n = 2) observed flash-point of 1-chloro-2,3-dimethylbenzene was 71.9 ± 0.2 °C, adjusted to 101.3 kPa.
