Pressure decay leak testing

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.
