7.2.1

Test Execution

Run the test according to the test
procedure that you selected and
programmed.
7.2.2

Switching Off the Device

When switching off the unit,
proceed as follows:
– Run through the test to the end.
– Close the compressed air intake on
the compressed air supply.
– Run the log-off function.
– Turn off the main switch.
7.2.3 Switching off the Device on the
Failure of the Power Supply
In the event of a power failure, all
valves will be switched to a secure
state. This guarantees that the filter
housing is vented. The ongoing test
is cancelled. No test result will be
available.
Loss of Compressed Air
In the event that the compressed
air supply stops, the test is auto-
matically cancelled and an error
message appears. "Target pressure
not reached". The system is vented
automatically. When the supply
of compressed air resumes, the
unit must be restarted and the
test repeated.

Test Conditions

To obtain reliable and reproducible
test results, observe the following:
– Run the integrity test at room
temperature (approx. 15–30°C),
whenever possible.
– During an integrity test run, always
avoid any temperature changes.
– The upstream side of the filter
system must be absolutely leak-free
(Run pressure hold test).
– Do not connect the integrity tester
to pressurized systems.
– If you wish to use other types of
compressed gas and|or wetting
fluids not specified by Sartorius
Stedim Biotech, consult your local
Sartorius Stedim Biotech office or
Sartorius Stedim Biotech Technical
Support (see Chap. 8.1)
– For the Water Intrusion Test,
the surface tension of the water
must be > 70 dyn/cm.
– Always enter correct test parame-
ters. Incorrect test parameters will
lead to incorrect test results or
erroneous evaluations.
Reference Pressure
On delivery, the Sartocheck
is set to a reference pressure of
1000 mbar.
Calibration
The integrity tester should be
re-calibrated at least once a year,
twice being preferable.
7.3.2

Test Selection

With the Sartocheck
can directly select a particular
integrity test method. This greatly
simplifies programming the data for
a test, since only the parameters
that are relevant for the selected
test are displayed.
You can select any of the following
test methods:
Test Methods
1 Diffusion Test
2 Bubble Point Test
3 Diffusion Test and Bubble Point
Test (complete test)
4 Water Intrusion Test
5 Water Flow Test
6 Pressure Drop Test
7 Multipoint Diffusion Test
8 Volume Measurement
9 Customer-Specific BP
10 Customer-Specific Multipoint
Diffusion Test
System Venting
At the end of each test, after a
power failure or after switching
off the unit during a test, the
system is automatically vented.
