Reference
Endpoint:
flash point of flammable liquids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
03-25 April 2006
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Remarks:
The study was conducted according to an internationally recognised method, and under GLP. No deviation affected the quality of the study. The substance is considered to be adequately characterised. Therefore full validation applies.
Qualifier:
according to
Guideline:
EU Method A.9 (Flash-Point)
Deviations:
no
Principles of method if other than guideline:
Not applicable
GLP compliance:
yes (incl. certificate)
Remarks:
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
Remarks:
GHS and EU-CLP criteria not met
Conclusions:
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 fully reliable experimental study, conducted according to a recognized EC method and under GLP, is available. Therefore it is considered as a key study, and the result is retained as key data.
