Leak Testing Methods
Burst Test
The Burst Leak Test requires filling a product slowly through a flow valve. After the burst, the pressure rapidly drops to near zero.
Continuous Flow Test
The Continuous Flow leak test method allows the flow sensor to measure the flow faster.
Crack Test
A Crack Leak test is set up to measure the pressure at which a product, such as a check valve, opens and allows air to flow through.
Exercise/Fluff Leak Test
As the name implies, the exercise/fluff leak test is used as a settling or seating step in order to condition the part before a test program is initiated
Force Decay Test
The Force Decay leak test is used to test the seal integrity of a flexible or semi-rigid package that contains a headspace. It is well suited to test non-porous package material such as films, foils or laminates.
Laminar Flow Leak Test
The Laminar Flow leak test is a sensitive flow technique that is commonly used on large volumes where the leak integrity specification is high.
Mass Flow Leak Test
The mass flow leak test measures the amount of air passing through an object using units of measurement of sccm or liters/time period.
Occlusion Leak Test
Occlusion Leak test is used to test a product’s open passages by trapping pressure inside the product, then measuring an expected pressure loss.
Pressure Decay Leak Test
This test method measures the drop in pressure on a gauge (transducer) during the leak test.
Pressure Rise Test
A Pressure Rise Leak test works in the opposite way of a pressure decay test.
Seal Creep Leak Test
A Seal Creep Leak test tests products that must hold a certain amount of air pressure without failing, but may increase in size or “creep up” during the test.
