flash point of flammable liquids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
The study was conducted according to an internationally recognised method. No deviation was reported. The test substance is adequately characterized with isomers composition. Therefore full validation applies.
according to guideline
EU Method A.9 (Flash-Point)
GLP compliance:
Type of method:
closed cup
Dynamic viscosity of test material:
(no data)
Flash point:
141 °C
Atm. press.:
993 hPa
Remarks on result:
other: measured; accuracy +/-2°C
Key result
Flash point:
142 °C
Atm. press.:
1 013 hPa
Remarks on result:
other: corrected flash point

FP observed : 141 °C at 993 hPa (atmospheric P)

FP corrected = FP observed + 0.23*(101.3 kPa – atmospheric P in kPa)

FP corrected : 142 °C at 1013 hPa Prepared

Temperature: corrected to a pressure of 1013 hPa according to reference ASTM D3278-96, p 4).

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, the test substance is NOT a flammable liquid according to CLP and GHS criteria.
Executive summary:

The flash point of the test substance was determined according to EU A9 guideline, closed cup method.

The test was carried out in duplicate, and the observed result was corrected to normal atmospheric pressure.


The flash point of the test substance is 142 °C under 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:
142 °C

Additional information

A fully reliable experimental study, conducted according to a recognized EC method (closed cup), is available. 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.
