8.2 Methods
8.2.1 Measuring according to ASTM D7094
This test method covers the determination of the flash point of pure chemicals, fuels (pure and contaminated), fuel
oils, lube oils (pure and contaminated), solvents, and other liquids.
This method measures the flashpoint with static measuring parameters that can’t be changed by users in order to
properly follow the ASTM D7094.
If measuring settings like sample ID, Temperature range and dilution curve were adjusted already the method can be
selected.
When all parameter were adjusted, prepare the samples and the sample cup (2 ml cup volume) for the test.
Sample stirring is automatically activated for this method. Please do not forget to place the
magnetic stirrer in the sample cup prior to starting the measurement!
8.2.2 Screening method for ASTM D7094
In order to check the flashpoint of an unknown sample a fast screening method with ASTM D7094 SCR features can be
used to get a quick idea of the liquid before the proper ASTM D7094 method can be used. To get the information at
which temperature the flashpoint occurs the temperature range must be entered where the flashpoint is expected.
The heating rate can be changed to get a quick idea in what range the flashpoint of the unknown sample appears.
When all parameter have been adjusted, prepare the sample and the sample cup (2 ml cup) for the test.
8.2.3 Measuring according to ASTM D6450
This test method covers the determination of the flash point of pure chemicals, pure hydrocarbons, fuels, fuel oils,
lube oils, solvents, and other liquids.
This method measures the flashpoint with static measuring parameters that can’t be changed by users in order to
properly follow the ASTM D6450.
If measuring settings like sample ID, Temperature range and dilution curve were adjusted already the method can be
selected.
When all parameter have been adjusted, prepare your sample and the sample cup (1 ml cup volume) for the test.
Sample stirring is automatically activated for this method. Please do not forget to place the
magnetic stirrer in the sample cup prior to starting the measurement!
8.2.4 Screening Method for ASTM 6450
In order to check the flashpoint of an unknown sample a fast screening method with ASTM D6450 SCR features can be
used to get a quick idea of the liquid before the proper ASTM D6450 method can be used. To get the information at
which temperature the flashpoint occurs the temperature range must be entered where the flashpoint is expected.
