(+) – yes, (-) – no

The value of flash point was corrected due to the deviation of the thermometer

and atmospheric pressure:

C – determined flash point after including a thermometer deviation = 66.8ºC;

p – ambient barometric pressure = 101.8 kPa.

T = C + 0.25 (101.3 – p) = 66.8ºC + 0.25(101.3 kPa – 101.8 kPa) ≈ 66.5ºC

Measurement uncertainty: 1.2ºC.

Interpretation of results:
other: No category (CLP Regulation EC no. 1272/2008)
Conclusions:
The flash point of the test item was determined to be 66.5ºC.
Executive summary:

In accordance with GLP study and EU A.9 method, the determination of flash point was carried out. The flash point of the test item was determined by the Pensky Martens Closed Tester Method. Three measurements were performed. The mean flash point of the test substance was found to be 66.8 ºC. After correction due to deviation of the thermometer and atmospheric pressure the final flash point of the test item was determined to be 66.5 ± 1.2ºC at 101.3 kPa.

Description of key information

Key study: Test method EU A.9. GLP study. The flash point of the test item was determined to be 66.5ºC at 101.3 kPa.

Key value for chemical safety assessment

Flash point at 101 325 Pa:
66.5 °C
