A proof pressure test is a type of non-destructive test where the component is pressurized to a determined pressure and held there in order to verify that the component can withstand the pressure. The pressure requirement is usually two to six times the normal operating pressure, and the failure criteria usually include leaking or deformation of the part. Proof testing can verify the maximum pressure safety factor is being met and help meet other quality and safety specifications.
Proof pressure testing is often a requirement in the aerospace and defense industries that need to ensure that every part in an assembly is certified to meet certain pressure requirements. Sometimes every part will need to be tested, or a number of samples out of each batch of parts. With our calibrated instruments traceable to NIST and ISO 17025:2017 quality program Clark Testing is ready to perform the proof pressure tests needed to qualify your parts for use.
