Fixturing for Leak Testing: Plan ahead to get the most out of your leak detector

摘要

In the abstract, it seems like such a simple thing - figuring out whether or not a product is leaking. However, the reality of performing this task quickly and reliably can be incredibly complex. Pressure decay systems, mass flow systems, helium or hydrogen accumulation, helium or hydrogen sniffers, mass spectrometers, residual gas analyzers: Life has changed dramatically since when you were a kid and would dunk a bicycle inner tube in a bucket of water to figure out where to patch a slow leak. (Although there are still some manufacturers using "water dunk test" systems to check their products.)
