Failsafe Leak Testing
|
From InterTech Development Company
Failsafe leak testing, where one never misclassifies a bad part as a good part, is doable. Better yet, good parts are never misclassified as bad parts and yield is maximized. However, this standard of perfection is achievable only if one understands and manages all the factors that can undermine leak-testing integrity. By understanding the limitations of failsafe leak testing in the most widely applicable method, mass flow leak testing, practical steps can be taken to manage these factors so that quality standards are uncompromised.
Whether a mass flow leak test is conducted upstream or downstream impacts both the difficulty of testing and the likelihood of making it failsafe. In upstream testing, a part is pressurized and the leak rate is determined by measuring what leaks into the part to replace what is leaking out. If the testing requirements are not as rigorous and the pressure requirements are not that high—for example, leak testing a casting at 10 psi—an upstream test will usually suffice.
Products & Services
Leak testing equipment is used to measure the escape of liquids, vacuum or gases from sealed components or systems.
