Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Flash point
Administrative data
Link to relevant study record(s)
- Endpoint:
- flash point of flammable liquids
- Data waiving:
- study technically not feasible
- Justification for data waiving:
- the study does not need to be conducted because the flash point is only relevant to liquids and low melting point solids
- Justification for type of information:
- JUSTIFICATION FOR DATA WAIVING
In accordance with paragraph R.7.1.9.2. of ECHA’s Guidance on Information Requirements and Chemical Safety Assessment Chapter R.7a: Endpoint specific guidance (Version 6.0, July 2017), flash point is defined as “the lowest temperature of the liquid (as measured in a prescribed manner) at a pressure corrected to 101.325 kPa, at which application of an ignition source causes the vapour of the liquid to ignite momentarily and the flame to propagate across the surface of the liquid under the specified conditions of test”.
The test item is a solid under atmospheric conditions (OCSPP 830.6303; R. Butler (2018)) with a mean melting point range of 59.2 - 81.0 °C ± 0.5 °C (EU Method A.1.; R. Butler (2018)). Whilst melting of the test item does commence within the classification limits for flammable liquid category 3 (Flash point ≥ 23 °C and ≤ 60 °C), the test item is not completely molten below 60 °C. The test item is therefore not regarded as a liquid within the classification criteria for the flammable liquids hazard.
In accordance with expert opinion, a flash point study was not conducted as the test item does not meet the classification criteria for this hazard class based on available data.
