The normal Multipoint Diffusion Test does not determine a pass or fail result.
This Customer-Specific Multipoint Diffusion Test allows the user to enter a maximum
diffusion limit line. Up to eight (8) points can be used to define this limit line
(pressure vs. diffusion). During test execution the actual measured diffusion will
be compared to this limit line to determine a pass or fail result.
This test method measures the net volume of the system (e.g. filter housing).
®
The Sartocheck 4 plus uses its internal or external reference tank pressurized to the
programmed pressure to determine the unknown volume. This is not an integrity test.
Rather, this test enables net volume validation of vent filter installation for water
intrusion tests using an external pressure sensor, for instance.
Please ask for Sartorius Stedim Biotech support before performing any net volume
validation.
