Atmospheric pressure = 100.9 kPa

Corrected flash point: 69.1 °C

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 69 ± 2 °C.
Executive summary:

The flash point of the test material was investigated in accordance with the standardised guideline EU Method A.9., under GLP conditions using closed cup apparatus.

An aliquot (2 mL) 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.

Under the conditions of this study, the flash point of the test material has been determined to be 69 ± 2 °C.

Additional information

The flash point of the test material was investigated in accordance with the standardised guideline EU Method A.9., under GLP conditions using closed cup apparatus. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).

An aliquot (2 mL) 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.

Under the conditions of this study, the flash point of the test material has been determined to be 69 ± 2 °C.
