- Endpoint:
- flash point of flammable liquids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 02 June 2017 to 14 June 2017
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Reason / purpose for cross-reference:
- reference to same study
- Reason / purpose for cross-reference:
- reference to same study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.9 (Flash-Point)
- Version / remarks:
- 2008
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- closed cup
- Flash point apparatus:
- Setaflash apparatus
- Key result
- Flash point:
- 129 °C
- Atm. press.:
- 100.5 kPa
- Interpretation of results:
- other: Not classified in accordance with EU criteria
- Conclusions:
- Under the conditions of this study the flash point of the test material has been determined to be 129 ± 2 °C.
- Executive summary:
The flash point of the test material was determined in accordance with the standardised guideline EU Method A.9, under GLP conditions.
An aliquot of the test material was transferred to the sample cup of the Setaflash 30000-0 tester. The sample was heated and allowed to equilibrate at the set temperature. The test flame was introduced into the sample cup for approximately 2.5 seconds by sliding the cup shutter open. Observations were made for ignition of the vapour. If no ignition occurred, the temperature was increased and the test flame re-introduced. This was repeated until the lowest reproducible temperature at which a flash occurred, using a fresh sample, was determined.
At the atmospheric pressure of 100.5 kPa, the observed flash point was 129.0 °C and the corrected flash point was 129.2 °C.
Under the conditions of this study the flash point of the test material has been determined to be 129 ± 2 °C.

Additional information
The flash point of the test material was determined in accordance with the standardised guideline EU Method A.9, under GLP conditions. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).
An aliquot of the test material was transferred to the sample cup of the Setaflash 30000-0 tester. The sample was heated and allowed to equilibrate at the set temperature. The test flame was introduced into the sample cup for approximately 2.5 seconds by sliding the cup shutter open. Observations were made for ignition of the vapour. If no ignition occurred, the temperature was increased and the test flame re-introduced. This was repeated until the lowest reproducible temperature at which a flash occurred, using a fresh sample, was determined.
At the atmospheric pressure of 100.5 kPa, the observed flash point was 129.0 °C and the corrected flash point was 129.2 °C.
Under the conditions of this study the flash point of the test material has been determined to be 129 ± 2 °C.
