7.13 Plate Holder Test This test sequence may be programmed on the Sartocheck 4 plus Filter tester but
may only be performed if a Bag tester MultiUnit is connected. The test sequence
is designed for leak testing of 2 dimensional bags (e.g. Flexboy) being maintained
between 2 metal plates during the test e.g. using the FlexAct BT trolley equipped with
fleeces. The test sequence is based on the change in pressure within the bag system
including connected tubes.
The pressure drop measured in the process can be used as a direct measure of the bag
set-up leak tightness and absence of pinholes or similar defects, provided that the
upstream volume of the system is constant.
Enter parameters for the plate holder test
Test pressure: from 3–300 mbar
Stabilization time: 10-3600 seconds.
Test time: 10-3600 seconds
Max. pressure drop: 1-programmed test pressure
Please verify the test parameters for the bag being tested. Applying too high a test
pressure may jeopardize the integrity of the bag.
Since the viscosity of the remaining liquid may influence the leak rate of an eventual
pinhole, please do not mix up pre-use test values with specifically validated post-use
values.
This test can also be used for testing vessels as long as they resist the applied
pressure.
