Pressure decay is one of the most widely used methods of leak testing in manufacturing and is ideal for a sealed component with an access port. In this test, a product is attached to a leak tester and filled with air. Once pressurized, the air source is valved off and the pressure is allowed to settle. Pressure decay leak testing uses a pressure loss measurement to identify a specific leak rate, making it one of the most effective means of testing for leaks in virtually any type of part. It is a simple test that is easy to automate and ideal for isolating even the smallest leaks. You can conduct pressure decay testing using either air .
