Reference
Endpoint:
flash point of flammable liquids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
experimental dates: 10-25 May 2012
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 was reported. The substance is adequately characterised. Therefore full validation applies.
Reason / purpose:
reference to same study
Qualifier:
according to
Guideline:
EU Method A.9 (Flash-Point)
Version / remarks:
Regulation (EC) No 440/2008
Deviations:
no
Qualifier:
according to
Guideline:
ISO 3679 (Determination of flash point - Rapid equilibrium closed cup method)
Version / remarks:
1983
Qualifier:
according to

Specific details on test material used for the study:
STORAGE CONDITIONS OF TEST MATERIAL
Refrigerator (between 0 and 10 °C under nitrogen)
Key result
Flash point:
147 °C
Atm. press.:
97.6 kPa

Preliminary determination: Flash at 146°C

Determination 1 (fresh sample): Flash at 146°C

Determination 2 (fresh sample): Flash at 146°C

 

Atmospheric pressure: 97.6 kPa

Corrected flash point: 146.86 °C

The final value is rounded to 147°C, with an accuracy of ± 2°C.

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 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 method (listed in EU A.9 guideline), using a closed cup equilibrium method.

Both duplicate determinations gave a FP of 146°C, under atmospheric pressure of 97.6 kPa. The measured value was then corrected to normal atmP.

 

The normal flash point of the test substance has been determined to be 147 ± 2 °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:
147 °C

Additional information

A fully reliable experimental study, conducted according to a recognized EU/ISO guideline (equilibrium closed cup method) and under GLP, 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. (see IU Section 4.13 endpoint summary for justification of non-classification)
