Safety components

There are approximately 180 parts or systems that have been leak tested on a normal car. Leak rates range from 100 Sccm down to 10E-8 Sccs.

Even though pressure decay and mass flow are often used, tightness demands on automotive components are getting heavier to meet EPA regulations and for safety reasons (DOT requirements). These specifications can only be met using tracer gas leak test methods such as helium.
