RESULTS

Temperature [°C] Observations
16, 21, 26, 31, 36, 41, 46, 51, 56, 61, 66, 66 (fresh sample), 71, 76, 81, 86, 91, 96, 101, 106, 106 (fresh sample), 111, 116, 121, 126, 131, 136, 141, 146, 151 No flash.
156 A flash spread across the sample cup.
151 (fresh sample), 152 No flash.
153 A flash spread across the sample cup.
151 (Fresh Sample) No flash.

151 (Fresh Sample)

No flash. 

153 (Fresh Sample) A blue flash spread across the sample cup.
153 (Fresh Sample) A blue flash spread across the sample cup.

Atmospheric pressure = 101.02 kPa.

Corrected flash point = 153.070 °C.

Interpretation of results:
other: The flash point is the primary indicator for ease of ignition of liquids. According to CLP regulation, a substance is not considered flammable when the flash point is greater than 60 °C.
Conclusions:
According to Council Directive 92/69/EEC A.9, the flash point of the test item was determined to be 153 ± 2 °C 101.02 kPa.

Description of key information

The flash point of the test item was determined to be 153 ± 2 °C at 101.02 kPa.

Key value for chemical safety assessment

Flash point at 101 325 Pa:
153 °C
