- 7.1.1 – Bitumen method
Aimed at viscous or thick samples at ambient temperature.
Stirring and test will effectively start up when sample has reached the preheating temperature.
! The stirring system can be severely damaged if the sample is not
fluid enough or if the preheating temperature is too low.
- 7.2 – STARTING A TEST IN « SEARCH » MODE FOR A
PRODUCT CORRESPONDING TO THE SPECIFICATIONS OF
THE PENSKY MARTENS METHOD AND FOR WHICH THE
FLASHPOINT IS UNKNOWN.
Enter the expected T° C
Enter a sample identification number by pushing on (-) key
Start the test like in 7.1
The instrument carries on flame dipping as soon as the beginning of the test, every 1 or 2 °C.
The slope is automatically set up according to selected method.
Note : for a larger « search » area without several selections of expected temperature, it’s
possible to modify through keyboard the alarm and safety stop related to expected
temperature.
- 7.3 – QUICK METHOD (OUT OF STANDARD)
The method consists of performing tests with the A method, on known samples with a temperature
slope higher than 10 °C /min.
This method allows to rapidly approach the Flash Point value of the sample. In order to get the
correct value, a second test with the standardized method is necessary.
