Endpoint:
flash point of flammable liquids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
28/03/2011
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Remarks:
The study was conducted according to an internationally recognised method. Substance ID is adequately specified with purity. Therefore full validation applies.
Qualifier:
according to

ISO 3679 (Determination of flash point - Rapid equilibrium closed cup method)
Version / remarks:
1983
Qualifier:
according to
Guideline:
ISO 3680 (Determination of flash/no flash - Rapid equilibrium closed cup method)
Version / remarks:

Qualifier:
according to
Guideline:
ASTM D3278 (Standard test methods for flash point of liquids by small scale closed-cup apparatus)
Version / remarks:
October 1997
GLP compliance:
no
Type of method:

Flash point apparatus:
other: Rapid Flash Tester RT-1
Dynamic viscosity of test material:
no data
Flash point:
143 °C
Atm. press.:
977 hPa
Key result
Flash point:
144 °C
Atm. press.:
1 013 hPa

Temperature corrected to a pressure of 1013 hPa according to reference ASTM D3278-96.

accuracy +/-2°C

Interpretation of results:
GHS criteria not met
Remarks:
GHS and EU-CLP criteria not met
Conclusions:
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 determined according to EU A9 guideline, closed cup method.

Duplicate runs were performed. The mean measured value was then corrected to normal atmP.

The normal flash point of the test substance has been determined to be 144 ± 2 °C.

Specific details on test material used for the study:
Storage condition of test material: Refrigerator (between 0 and 10°C under nitrogen)
Flash point:
146 °C
Atm. press.:
97.7 kPa
Key result
Flash point:
147 °C
Atm. press.:
101.325 kPa

Preliminary determination: 148°C

Determination 1 (fresh sample): 146°C

Determination 2 (fresh sample): 146°C

Atmospheric pressure = 97.7 kPa

The final (corrected) 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 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 determined under GLP according to ISO 3679 (listed in EU A9 guideline), using a closed cup equilibrium method.

Two main runs were performed. Both determinations gave a FP of 146°C, under atmospheric pressure of 97.7 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 according to CLP and GHS criteria.

Key value for chemical safety assessment

Flash point at 101 325 Pa:
144 °C

Additional information

Two fully reliable studies, conducted according to a recognized EC method, and one under GLP, are available. Both are considered equivalent and key studies. For safety reason, the lower result is retained as key data.

This result is relevant for the classification regarding flammable properties. (see IU Section 4.13 endpoint summary for justification of non-classification)
