Production Leak Detection Systems
This method involves measuring the drop in pressure inside the part over time as a result of escaping material.
The test typically consists of the following steps:
 |
Charging the part to test pressure |
|
Allowing the pressure to stabilize |
|
Measuring the drop in pressure during test |
The following illustration shows a typical pressure decay test:
