Reference
Preliminary test
Atmospheric pressure: 99.0 kPa
Relative humidity: About 22 %
Temperature(°C) | Flash | ||
Observed temperature | Corrected temperature with the calibration curve (CT) | Corrected to Patm | |
81.1 | 79.5 | 80.0 | No |
91.3 | 89.5 | 90.0 | No |
101.4 | 99.5 | 100.0 | No |
111.6 | 109.5 | 110.0 | Yes |
106.5 | 104.5 | 105.0 | No |
The flash point was observed between 105.0 °C and 110.0 °C (corrected values).
Main test
Atmospheric pressure: 99.0 kPa
Relative humidity: About 23 %
Temperature (°C) |
| ||
Observed temperature (OT) | Corrected temperature with the calibration curve (CT) | Corrected to Patm (C) | Flash observation |
95.8 | 94.0 | 95.0* | Yes |
90.8 | 89.0 | 90.0 | No |
91.8 | 90.0 | 91.0 | No |
92.8 | 91.0 | 92.0 | No |
93.8 | 92.0 | 93.0 | No |
94.8 | 93.0 | 94.0 | No |
95.8 | 94.0 | 95.0 | No |
96.9 | 95.0 | 96.0 | Yes |
*As a flash point was recorded at 95.0 °C, the temperature was decreased by 5 °C.
Conclusion
The flash point of the test item was 95.0 ± 1.0 °C (corrected value).
Description of key information
Flash point: 95.0 ± 1.0 °C at 1013 hPa (ISO 3679)
Key value for chemical safety assessment
- Flash point at 101 325 Pa:
- 95 °C
Additional information
A measured flash point value of 95.0 ± 1.0 °C at 1013 hPa was determined for the substance using a rapid equilibrium closed-cup method in accordance with ISO 3679 Test Method and in compliance with GLP. The result is considered to be reliable.
In secondary sources to which reliability could not be assigned, flash point values of 85 °C and 88 °C at 1013 hPa were reported for the substance with the use of relevant closed-cup methods.
A measured flash point value of 95.0 ± 1.0 °C and a predicted boiling point of 200 °C indicate that the substance should not be classified for flammability in accordance with Regulation (EC) No. 1272/2008.
