The pressure drop occlusion leak test works like this – you pressurize the part and then measure the change when the input pressure is removed. If your catheter is working properly then the pressure drops to zero – or an otherwise accepted figure – in a fixed time. If it doesn't, then the limit recognized by the instrument isn't met.

Method 1: Diagram 1 shows a plastic container being tested utilizing a gage type transducer. If the container is pressurized to 100 psi and then the valve is closed, the transducer will sense a leak/decay in pressure in the container, if given enough time. Small leaks can be detected in this manner, although the process can be time consuming.
