flash point of flammable liquids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
03-25 April 2006
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
The study was conducted according to an internationally recognised method, and under GLP. No deviation affected the quality of the study.
according to guideline
EU Method A.9 (Flash-Point)
Principles of method if other than guideline:
Not applicable
GLP compliance:
yes (incl. QA statement)
signed 24 February 2006
Type of method:
closed cup
Flash point apparatus:
Setaflash apparatus
Dynamic viscosity of test material:
No data.
Key result
Flash point:
137 °C
Atm. press.:
ca. 101 325 Pa

In a first test, the temperature was increased by successive steps of +5.0 °C, using 4 mL of sample. Flashing occurred at 140 °C.

The procedure was reproduced in duplicate using a new 4.0 mL sample for each replicate test, and the temperature was regularly increased by successive steps of 0.5 °C. Flashing occurred at 138.0 °C and 137.5 °C, successively.

Interpretation of results:
GHS criteria not met
GHS and EU-CLP criteria not met
The flash point of test substance is above the classification thresholds of 60°C (CLP criteria) or 93°C (GHS criteria). Therefore, test substance is not a flammable liquid according to CLP and GHS criteria.
Executive summary:

The flash point of the test substance was determined under GLP according to EU Method A.9, using a closed cup Setaflash apparatus method.


After a screening determination, two main runs were performed, and found consistent. The lower rounded result was retained.

The flash point of test substance has been determined to be 137°C.

Description of key information

Measured FP (rounded down) = 137°C

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:
137 °C

Additional information

A reliable experimental study, conducted according to a recognized EC method and under GLP, is available. It is considered as a key study, and the result is retained as key data.
