- Study period:
- 15 September 2016 to 19 September 2016
- Reliability:

- Type of method:
- equilibrium method closed cup
- Flash point apparatus:
- Setaflash apparatus
- Specific details on test material used for the study:
- PERFORMANCE OF THE TEST
- An aliquot of test item (2 mL for temperatures up to 100 °C and 4mL for temperatures above 100 °C) 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 was re-introduced.
- The procedure was repeated until the lowest reproducible temperature at which flash occurred using a fresh sample was determined.
CALCULATION
- The flash point is the lowest temperature at 101.3 kPa at which the test liquid in a closed test vessel evolves vapours, under the conditions defined in the test method, in such an amount that a flammable vapour/air mixture is produced in the test vessel.
- The flash point was corrected for atmospheric pressure using the equation Corrected flash point = C + 0.23 (101.325 – p) where C = observed flash point (°C) and p = ambient atmospheric pressure (kPa). - Key result
- Flash point:
- 232 °C
- Remarks on result:
- other: experimental result was corrected for atmospheric pressure
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The flash point of the test item was determined to be 232 ± 2 °C using the closed cup equilibrium method.
- Executive summary:
GUIDELINE
The determination was carried out using a closed cup Setaflash 30000-0 flash point tester and was designed to be compatible with Method A.9 Flash Point of Commission Regulation (EC) No 440/2008 of 30 May 2008.
RESULTS
The flash point of the test item was determined to be 232 ± 2 °C using the closed cup equilibrium method.
