Standard Guide for Preparation of a Leak Testing Specification
For any product to be tested the geometrical complexity will vary widely. However, the basic concept of determining an operative leakage specification regardless of geometries is much the same for all, whether it be simple, ordinary, or complex. The data required for writing the OS, which is total leakage (moles), time(s), and pressure difference across the leak, are either available or can be determined by tests or measurements.
