Gas-Based Production Leak Testing Techniques For Automotive Components

This paper outlines the methodology to 1) determine what leak rate specification is appropriate for a given automotive component, 2) arrive at the gas-based leak test method that is best suited for the situation, and 3) perform the requisite calculations to confirm the choice of test method. Also provided are summary tables (based upon actual industry experience) relating component type, typical leak rate specification, test method used, and (production) sensitivity range of the method utilized.
