Reference
Calibration
The calibration with n-undecane and n-hexadecane was carried out in duplicate. The measured values after correction for atmospheric pressure were:
- n-undecane 1sttrial : 68.8 °C
2ndtrial : 66.8°C
- n-hexadecane 1sttrial : 128.8 °C
2ndtrial : 130.8 °C
These measured values are within the acceptance limits.
The accuracy of the method varies according to the flash point range used. The maximum estimated accuracy is ±2 °C.
The estimated accuracy of the manometer ± 0.1 kPa.
Flash point of test substance
With the expected flash point of 190 °C the first dipping of the ignition source was at 169 °C.
The determination resulted in:
- recorded flash point : 197.1 °C
- atmospheric pressure : 102.2 kPa
- corrected flash point : 196.9 °C
This means that the flash point of the test substance is 197 °C.
Description of key information
The flash point of the substance is 197 °C.
Key value for chemical safety assessment
- Flash point at 101 325 Pa:
- 197 °C
Additional information
The GHS criteria to classify this substance as a flammable liquid does not apply. Its flash point is far above 60 °C.
