- Version / remarks:
- March 2015
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.9 (Flash-Point)
- Version / remarks:
- 2008
- Deviations:
- no

- yes (incl. QA statement)
- Type of method:
- equilibrium method closed cup
- Flash point apparatus:
- Setaflash apparatus
- Key result
- Flash point:
- < -19.5 °C
- Atm. press.:
- 1 013 hPa
- Interpretation of results:
- Category 1 (extremely flammable liquids) based on GHS criteria
- Conclusions:
- A flash point value of <-19.5 ± 0.5°C at 1013 hPa was determined for the substance using a relevant test method and in compliance with GLP. The result is considered to be reliable.

A flash was observed at -19.5°C (corrected value). The test was then stopped as the lowest limit of temperature of the apparatus was reached.
Main test
No main test was performed.
Description of key information
Flash point: <-19.5°C ± 0.5°C at 101.3 kPa (ISO 3679)
Key value for chemical safety assessment
- Flash point at 101 325 Pa:
- -19.5 °C
Additional information
A measured flash point value of <-19.5°C ± 0.5°C at 1013 hPa was determined for the substance using a rapid equilibrium method in accordance with ISO 3679 Test Method and in compliance with GLP. The result is considered to be reliable and is selected as key study.
In available secondary sources to which reliability could not be assigned, closed-cup flash point values of <-5°C, -14°C, -26.1°C, -27°C and -28°C at 1013 hPa were reported for the substance. An open-cup flash point value of <79°C at 1013 hPa was also reported for the substance.
Flash point values of <-19.5°C and measured boiling points in the range 31.5 to 33°C indicate that the substance should be classified as Flammable Liquid Category 1 (H224: Extremely flammable liquid and vapour) according to the criteria of Regulation (EC) No 1272/2008.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
