Materials and methods
Test guidelineopen allclose all
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- EU Method A.9 (Flash-Point)
- Version / remarks:
- 2008
- Qualifier:
- according to guideline
- Guideline:
- other: ASTM D7094: “Standard Test Method for Flash Point by Modified Continuously Closed Cup (MCCCFP) Tester”
- Version / remarks:
- 2012
- Deviations:
- no
- Principles of method if other than guideline:
- According to ECA.9 the flash point can be determined by an equilibrium method or a non-equilibrium method. Several methods are mentioned in the guideline. ASTM D7094 is not one of the methods mentioned in the guideline but is a commonly used and safer (low sample volume) alternative for the non-equilibrium ISO 2719 Pensky martens closed cup method.
- GLP compliance:
- yes
- Type of method:
- other: modified continuously closed cup
- Flash point apparatus:
- other: Eraflash (Eralytics, Austria)
- Dynamic viscosity of test material:
- no data

Results and discussion
Flash point
- Key result
- Flash point:
- 140 °C
- Atm. press.:
- 1 013 hPa
Any other information on results incl. tables

Test 2: 140°C
Applicant's summary and conclusion
- Interpretation of results:
- other: not classified under CLP or GHS
- Conclusions:
- The flash point of the substance was determined to be 140°C (at 1013 hPa).
- Executive summary:
The flash point of the substance was determined using the modified continuously closed cup ASTM D7094 method (GLP study). The flash point was determined in duplicate obtaining a value of 140°C (at 1013 hPa).
