Reference
Endpoint:
flash point, other
Type of information:
experimental study
Adequacy of study:
key study
Study period:
23 April to 21 June, 2012
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
guideline study with acceptable restrictions
Justification for type of information:
The study was conducted according to an internationally recognised method, and under GLP. Experimental details are missing. This is not considered critical for the assessment. Therefore validation applies with acceptable restrictions.
Qualifier:
according to guideline
Guideline:
EU Method A.9 (Flash-Point)
Deviations:
not specified
Principles of method if other than guideline:
Not applicable.
GLP compliance:
yes (incl. QA statement)
Remarks:
GIPC; effective Jan.11, 2011, signed on Mar.11, 2011.
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:
- Physical appearance: Light yellow translucent liquid.
- Storage conditions of test material: At room temperature protected from direct sunlight.
Key result
Flash point:
162 °C
Remarks on result:
other: experimental pressure not specified

In first test, the temperature was increased by successive steps of +10.0 °C, using 4 mL of sample, flashing occurred between 160 °C and 170 °C.

The procedure was reproduced and temperature was regularly increased by successive steps of +1.0 °C: replicate test showed that no flash was observed at 161 °C, but flashing occurred at 162 °C in every case.

The mean Flash point was determined to be 162 °C.

Interpretation of results:
GHS criteria not met
Conclusions:
The flash point of test item was determined to be 162 °C. The flash point of the test substance is above the classification threshold of 60 °C (CLP criteria) and 93 °C (GHS criteria). Therefore, the test substance is NOT a flammable liquid according to CLP and GHS criteria.
Executive summary:

A GLP study was conducted to determine the flash point of test substance by closed cup method according to EU method A.9.

In first test the flashing occurred between 160 and 170 °C with increase in temperature of +10.0 °C. Replicate test were performed with increase in temperature of 1.0 °C in which no flash was observed at 161 °C but flashing occurred at 162 °C in every case.

The flash point of test item was determined to be 162 °C.

Description of key information

The flash point of test item was determined to be 162 °C. The substance is NOT classified according to CLP and GHS criteria.

Key value for chemical safety assessment

Flash point at 101 325 Pa:
162 °C

Additional information

A reliable experimental study, conducted according to a recognized EC method and under GLP, is available.
It is considered as a key study, and the result is retained as key data.
