Reference
Endpoint:
flash point of flammable liquids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2010-01-11 to 2010-01-20
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 test substance composition is adequately characterised with its purity. Therefore full validation applies.
Qualifier:
according to guideline
Guideline:
EU Method A.9 (Flash-Point)
Version / remarks:
Council Regulation (EC) No 440/2008 dated30 May 2008
Qualifier:
according to guideline
Guideline:
ISO 3679 (Determination of flash point - Rapid equilibrium closed cup method)
Version / remarks:
1983 (F)
Qualifier:
according to guideline
Guideline:
ASTM D3278 (Standard test methods for flash point of liquids by small scale closed-cup apparatus)
Version / remarks:
1996

Type of method:
equilibrium method closed cup
Flash point apparatus:
Setaflash apparatus
Dynamic viscosity of test material:
no data
Specific details on test material used for the study:
Storage condition of test material: Refrigerator (between 0 and 10°C under nitrogen)
Key result
Flash point:
173 °C
Atm. press.:
101.325 kPa

(detailed results are available in the study report)

Preliminary determination: flash observed at 172°C

Determination 1 (fresh sample): flash observed at 172°C

Determination 2 (fresh sample): flash observed at 172°C

Atmospheric pressure = 97.6 kPa

Corrected flash point = 172.86°C

precision: +/-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 a flammable liquid according to CLP and GHS criteria.
Executive summary:

The flash point of the test substance was measured under GLP according to ISO 3679-1983 closed cup rapid equilibrium method (listed in EU A9 guideline).

Two runs were performed, and the mean result was corrected for normal atmospheric pressure.

The flash point of the test substance is 173°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:
173 °C

Additional information

A fully reliable study, conducted according to a recognized EC method and under GLP, is available. Therefore, it is considered as a key study. The result is retained as key data.

This result is relevant for the classification regarding flammable properties.
