Endpoint:
flash point of flammable liquids
Type of information:
experimental study
Adequacy of study:
weight of evidence
Study period:
2011-02-17
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
guideline study without detailed documentation
Remarks:
ISO 13736:2008 specifies a method for the determination of the closed-cup flash point of combustible liquids having flash points between - 30,0 °C and 70,0 °C, inclusive. However, the precision given for this method is only valid for flash points in the range - 5,0 °C to 66,5 °C. The experiment termination date was 17 February 2011 so does not need to be performed under GLP or ISO 17025.
Qualifier:
according to guideline
Guideline:
ISO 13736 (Petroleum products and other liquids - Determination of flash point - Abel closed cup method)
Version / remarks:
1997
Deviations:

Principles of method if other than guideline:
ISO 13736:2008 specifies a method for the determination of the closed-cup flash point of combustible liquids having flash points between - 30°C and 70°C inclusive. However, the precision given for this method is only valid for flash points in the range - 5°C to 66.5°C.
GLP compliance:
no
Remarks:
Study pre-dates requirement for quality system or standard.
Type of method:
closed cup
Flash point apparatus:
Abel apparatus
Key result
Flash point:
25.5 °C
Atm. press.:
1 013 hPa
Interpretation of results:
Category 3 (flammable liquids) based on GHS criteria
Conclusions:
A measured flash point of 25.5°C at 1013 hPa was determined for the substance using a relevant test method. The result is considered to be reliable.

Description of key information

Flash point: 25.5 - 26°C at 1013 hPa (ISO 13736)

Key value for chemical safety assessment

Flash point at 101 325 Pa:
25.5 °C

Additional information

Three reliable measured flash point data are available for the submission substance. Measured flash point values of 25.5°C and 26°C at 1013 hPa were determined for the substance using an Abel closed-cup method in accordance with ISO 13736 Test Method. The results are considered to be reliable and are selected as weight of evidence.

The value is supported by another reliable flash point value of 23°C at 1013 hPa that was obtained for the substance using ASTM D3828-87.

In several secondary sources to which reliability could not be assigned, flash point values of 22°C, 24°C, 24.5°C, 26°C, 27.7°C and 28°C at 1013 hPa were reported for the substance.

Variations in the flash point values may be caused by variations in purity of the test substance and in the test method used. The key study is selected as the study most recently conducted and, therefore, relevant for current commercial products.

Flash point of 25.5 - 26°C at 1013 hPa and a measured boiling point of 123°C, indicate that the substance should be classified as a flammable liquid (Category 3) according to the criteria of Regulation (EC) No. 1272/2008.
