Occlusion Test Examples
The same pneumatic circuit employed in pressure decay testing is used in
occlusion testing; only the programming is different.
Thanks to the commonality of test circuits, it is possible to conduct
pressure decay tests followed by occlusion tests. This is easy to
accomplish with the program linking ability of Sprint LC.
Typically, a pressure decay test is conducted first, then open the product to
atmosphere and conduct an occlusion test.
Sealing the Product
Occlusion tests can be conducted by using a clamping device to seal the
product during the fill time and releasing the seal to allow the product to
flow to atmosphere. Alternatively, the product can be opened to the
atmosphere throughout the entire test.
Please refer to coupling valves starting on page 42 for more information
about coupling valves and how they work.
An occlusion test can be run with or without a clamping device to seal off
the product. We will now provide examples of both.
