Leak Testing 101—Part 4Helium leak detection methods for stringent leak-testing applications
Tue, 02/15/2011 - 04:30
In parts one, two, and three of this “Leak Testing 101” series, we discussed three methods of dry-air leak testing—pressure decay, differential pressure decay, and mass-flow leak testing—including the pitfalls and hidden costs inherent in two-step… Leak Testing 101—Part 3Testing topics

In parts one and two of this ongoing primer on leak testing, we discussed pressure-decay testing and differential pressure-decay testing, respectively. Although those leak-testing methods remain the most widely used, it is often because they are… Leak Testing 101—Part 2Differential pressure-decay leak testing

In part one of this series, we considered the pros and cons of pressure-decay testing. In part two, we’ll take a close look at a leak-testing method called “differential pressure decay.” This method is similar to simple pressure-decay testing… Leak Testing 101—Part 1What every quality engineer needs to know

Not too long ago, when you wanted a product to be leak-proof, you simply put it under water, made sure it didn’t bubble, and thereby concluded there were no leaks. Such “bubble testing” takes time and depends on the operator’s ability, making it…
