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:
- January 17, 2000
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:
- The study was conducted according to an internationally recognised method, and under GLP. No deviation affected the quality of the study. The substance is considered to be adequately characterised with its purity. Therefore full validation applies.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.9 (Flash-Point)
- Deviations:
- no
- Principles of method if other than guideline:
- Not applicable
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- inspected on May 7, 1999 / signed on July 2, 1999
- Type of method:
- equilibrium method closed cup
- Flash point apparatus:
- Setaflash apparatus
- Dynamic viscosity of test material:
- no data
- Specific details on test material used for the study:
- - Physical state: White gel
- Storage condition of test material: Stored in darkness at room temperature
- Preparation of the test substance: The test substance was melted at +50 °C - Key result
- Flash point:
- 142 °C
- Atm. press.:
- 101.3 kPa
- Remarks on result:
- other: accuracy: ± 1 °C
- Conclusions:
- Despite the test substance is solid a ambient temperature, this study is relevant for classification purpose, as the melting point is below the classification thresholds of 60°C (CLP criteria) or 93°C (GHS criteria), therefore the substance is liquid in this range.
As the test result is above these criteria, the substance is NOT classified as a flammable liquid in both systems. - Executive summary:
The flash point of the test substance was determined under GLP according to EU Method A.9 (Flash-Point), using a closed cup, equilibrium method.
After preliminary determination, three replicates were performed in the main test. Results were consistent, so the average value was retained, and corrected for normal atmospheric pressure.
The flash point of test substance has been determined to be 142 ± 1 °C at 101.3 kPa.
Reference
Preliminary test
Room temperature: 20.6 °C
Observed atmospheric pressure: 55.5 kPa
Humidity: 38% of saturated air
-13 assays were performed from +40 °C to +150 °C.
-No flash-point was observed up to +140 °C.
-A development of white smoke was observed at +100 °C.
-At +140 °C, a blue flame was observed (not considered as a flash-point)
-At +145 °C and +150 °C, a flash-point was observed.
Estimation of flash point: from +141 °C to +145 °C
Main test
Room temperature: 20.6 °C
Observed atmospheric pressure: 55.5 kPa
Humidity: 38% of saturated air
The main test was conducted thrice, with ± 1 °C interval, until ignition

Mean of 3 determinations = +141.74 °C (at 101.3 kPa); the mean of the three flash-point values was then rounded to the nearest 0.5 °C
The flash-point value of the test substance is + 142 ± 1 °C Observations: white smoke was observed at +100°C
Description of key information
The substance is NOT classified as a flammable liquid neither according to CLP Regulation criteria, nor to UN GHS.
Key value for chemical safety assessment
- Flash point at 101 325 Pa:
- 142 °C
Additional information
A fully reliable experimental study, conducted according to a recognized OECD/EC method and under GLP, is available. Therefore, it is considered as a key study, and the result is retained as key value.
Despite
the test substance is solid a ambient temperature, this study is
relevant for classification purpose, as the melting point is below the
classification thresholds of 60°C (CLP criteria) or 93°C (GHS criteria),
therefore the substance is liquid in this range.
As the test result is above these criteria, the substance is NOT
classified as a flammable liquid in both systems.
