- Type of method:
- other: The flash point determination test was performed according to the Tag closed cup method and the Cleveland open cup method, verification tests for Hazardous Material Type 4 designated under Japans Fire Defense Law. The specifics of the measuring procedure
- Flash point:
- 223 °C
- Atm. press.:
- 1 025 hPa
- Conclusions:
- Flash point determined as 223°C
- Executive summary:
The flash point determination test on the sample was performed according to the Tag closed cup method and the Cleveland open cup method, verification tests for Hazardous Material Type 4 designated under Japan's Fire Defense Law.
The flash point was determined to be 223°C.
During the Cleveland open cup method flash point test, smoke began to arise from the sample at around 150°C, however, no phenomenon, such as boiling or foaming, was observed even at the flash point. After the test, the sample had turned yellow and become extremely viscous.

# As the sample did not ignite after reaching the upper test temperature limit for the Tag closed cup method of 92°C, the flash point was assigned as “not determined”.
During the Cleveland open cup method flash point test, smoke began to arise from the sample at around 150°C, however, no phenomenon, such as boiling or foaming, was observed even at the flash point. After the test, the sample had turned yellow and become extremely viscous.
Description of key information
The flash point of the substance was determined to be 223°C.
Key value for chemical safety assessment
- Flash point at 101 325 Pa:
- 223 °C
