Atmospheric pressure: 100.2 kPa

Corrected flash point: 144.259 °C

Interpretation of results:

GHS criteria not met

Conclusions:

Under the conditions of this study the flash point of the test material was determined to be 144 ± 2 °C.

Executive summary:

The flash point of the test material was investigated in accordance with the standardised guideline EU Method A.9 under GLP conditions using the closed cup equilibrium method.

An aliquot (2 mL for temperatures up to 100 °C and 4 mL for temperatures above 100 °C) of the test material was transferred to the sample cup of the tester. The sample was heated and allowed to equilibrate at the set temperature. The test flame was introduced into the sample cup for approximately 2 seconds. Observations were made for the ignition of the vapour. This was repeated until the lowest reproducible temperature at which a flash occurred, using a fresh sample, was determined. The flash point was corrected for the atmospheric pressure

Under the conditions of this study the flash point of the test material was determined to be 144 ± 2 °C.

Description of key information

Additional information

The flash point of the test material was investigated in accordance with the standardised guideline EU Method A.9 under GLP conditions using the closed cup equilibrium method. The study was assigned a reliability score of 1 in accordance with the criteria for assessing data quality set forth by Klimisch et al. (1997).

An aliquot (2 mL for temperatures up to 100 °C and 4 mL for temperatures above 100 °C) of the test material was transferred to the sample cup of the tester. The sample was heated and allowed to equilibrate at the set temperature. The test flame was introduced into the sample cup for approximately 2 seconds. Observations were made for the ignition of the vapour. This was repeated until the lowest reproducible temperature at which a flash occurred, using a fresh sample, was determined. The flash point was corrected for the atmospheric pressure

Under the conditions of this study the flash point of the test material was determined to be 144 ± 2 °C.
