Materials and methods

Test guideline

Test guideline 1

Qualifier:

equivalent or similar to guideline

Guideline:

EU Method A.9 (Flash-Point)

Version / remarks:

2008

Test guideline 2

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:

not specified

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:

not applicable (the substance is a paste at room temperature)
