- other: 142 ± 2 °C ; Determination corrected to 101.325 kPa (conducted at 101.3 kPa)
- Interpretation of results:
- GHS criteria not met
- Remarks:
- Criteria used for interpretation of results: EU
- Conclusions:
- The flash point of the test item ST 08 C 19 has been determined to be 142 ± 2 °C at 101.325 kPa.
- Executive summary:
The flash point was determined using EU Method A.9 closed cup equilibrium method under GLP. An aliquot of the test item was transferred to the sample cup of the Setaflash tester. The sample was heated and allowed to equilibrate at the set temperature. The test flame was introduced into the sample cup for approximately 2½ 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. The results indicated are representative of the replicated (n ≥ 2) lowest temperature at which the test item (measured under the conditions of this study) causes the vapour of the liquid to ignite momentarily. Measurements were corrected to 101.325 kPa pressure. The flash point of the test substance has been determined to be 142 ± 2 °C at 101.325 kPa.

The test flame was introduced into the sample cup for approximately 2½ 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.
