Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 of flammable liquids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
guideline study without detailed documentation
The study was conducted similarly to internationally recognised method, but experimental details are lacking. Test substance is adequately specified with purity. Therefore validation applies with restrictions.
according to guideline
ISO 3679 (Determination of flash point - Rapid equilibrium closed cup method)
Version / remarks:
according to guideline
EU Method A.9 (Flash-Point)
GLP compliance:
Type of method:
equilibrium method closed cup
Key result
Flash point:
132 °C
Atm. press.:
981 mBar
Interpretation of results:
GHS criteria not met
GHS and EU-CLP criteria not met
The flash point of the test substance is above the classification thresholds of 60°C (CLP criteria) or 93°C (GHS criteria). Therefore the test substance is NOT classified as a flammable liquid.
Executive summary:

The flash point of the test substance was determined under GLP according to ISO 3679 (listed in EU A.9 guideline), using rapid equilibrium closed cup tester.

Measurement was recorded as 132°C under 981 mbar.

The flash point of the test substance has been determined to be 133°C, corrected to normal atmP.

Description of key information

The substance is NOT classified as flammable liquid neither according to CLP Regulation criteria, nor to UN GHS. 

Key value for chemical safety assessment

Flash point at 101 325 Pa:
133 °C

Additional information

A reliable experimental study, conducted according to a recognized ISO/EU method (closed cup), is available. Despite restrictions (due to lack of experimental details) it is considered as a key study, and the result is retained as key data.

This study is relevant for the classification regarding flammable properties, and sufficient for purpose.
