Description of key information
Three tests have been made and showed the following results :
| test # | result of flash point (°C) | method | batch | year of the test |
| test 1 | 57 | ISO 1523 | 2319 | 2010 |
| test 2 | 58 | ISO 1523 | 24/11 | 2010 |
| test 3 | 56 | ISO 1523 | 4984 | 2018 |
Key value for chemical safety assessment
- Flash point at 101 325 Pa:
- 56 °C
Additional information
The flash point of test item is comprised between 56°C and 58°C,, with a mean value at 57°C, so the essential is classified as a flammable liquid category 3.
