How to select test times
Testing times are dependent on factors such as part volume, test pressure, and leak rate. Other factors
that will affect testing are things like compliance of the part under pressure or vacuum. Some amount of
trial and error will be involved in finding acceptable values. However Zaxis has a few guidelines to follow in
aid of your task.
Fill
– The time should be long enough such that the part reaches the test pressure and is stable.
Settle
– During the settle time the part is isolated from any incoming air. If the media of the part is
susceptible to movement (compliance) the amount of pressure will drop slightly. The total settle time should
be long enough to allow for the initial movement of the part to calm.
Test
– The test time is dependent on the needs of the product and the leak rate. Compare the
decay of a good and bad part.
