Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Endpoint:
flash point of flammable liquids
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
study well documented, meets generally accepted scientific principles, acceptable for assessment
Reason / purpose for cross-reference:
reference to same study
Qualifier:
no guideline followed
Principles of method if other than guideline:
The flash-point of the test substance was determined by Cleveland open cup method. Since the measured flash-point is far above the classification limit and above 200 °C the open-cup method is accepted.
GLP compliance:
not specified
Type of method:
open cup
Key result
Flash point:
250 °C
Atm. press.:
ca. 1 013 hPa

No pressure reported. Atmospheric conditions (ca. 1013 hPa) are assumed due to open cup method.

Description of key information

Flash point: 250 °C at ca. 1013 hPa (open cup method)

No pressure reported. Atmospheric conditions are assumed due to method used.

Key value for chemical safety assessment

Flash point at 101 325 Pa:
250 °C

Additional information

The flash point changes with the composition of the substance.

Experimental data are available for two compositions (named grade one and grade two). The following flash points were determined for them:

Grade one: 250 °C

Grade two: 276 °C

The flash point for grade one (250 °C) is lower and used as key value, adopting a "worst case" approach.

The flash-points were determined with open cup method. Since the measured values are far above the classification limit and above 200 °C the open-cup method is accepted.
