Calibration and accuracy

    

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 substance

With the expected flash point of 175 °C the first dipping of the ignition source was at 154 °C.

 

The determination resulted in:

- recorded flash point   : 183.1 °C

- atmospheric pressure : 102.3 kPa

- corrected flash point  : 182.8 °C

 

This means that the flash point of the test substance is 183 °C.

Conclusions:
Based on the results in this report: The flash point of the substance is 183 °C.

Description of key information
