Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
guideline study without detailed documentation
The study was conducted according to an internationally recognised method, but non-GLP and without detailed documentation. The test substance is adequately characterised. Therefore validation applies with restrictions.
according to guideline
ASTM D3278 (Standard test methods for flash point of liquids by small scale closed-cup apparatus)
Version / remarks:
Principles of method if other than guideline:
ASTM D3278 is not listed in EU A9 guideline, nor in the CLP Regulation, but it is listed as a reference method in UN Manual of Tests and Criteria (6th edition, 2015; chapter 32.4.1.). Therefore it is considered suitable for classification purpose.
GLP compliance:
Type of method:
closed cup
Flash point apparatus:
Setaflash apparatus
Dynamic viscosity of test material:
No data. The test item is described as a viscous liquid.
Flash point:
149 °C
Atm. press.:
973 hPa
Key result
Flash point:
149.5 °C
Atm. press.:
1 013.25 hPa
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 measured (non-GLP) according ASTM D3278 standard (listed in EU A9 guideline), small scale closed cup method.

Experiment was performed in duplicate, and the result was corrected to standard atmospheric pressure.

The normal flash point of the test substance was determined to be 149°C.

Description of key information

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

Key value for chemical safety assessment

Flash point at 101 325 Pa:
149 °C

Additional information

A reliable experimental study, conducted according to a recognized ASTM guideline (small scale closed cup method) is available. Despite restrictions for method and non-GLP, 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. (see IU Section 4.13 endpoint summary for justification of non-classification)
