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
