I have just joined a company that manufactures instrumentation for measuring flow, pressure, temperature, level in the petrochemical, pharmaceutical, food processing and nuclear processing industries.
The sensors that are placed into the customer pipelines/tanks have a welded tip to which the sensor head/electronics is attached. Applications would include a wide range of fluids, powders and gasses at different pressures. The company normally perform a 100% helium fine leak test and have found that a new process/material does not perform as well as others. For this assembly we are considering setting a leak rate limit of 2 x 10-6 cc/sec but need to make sure this limit is OK.
I am familiar with the EN68000 Sealing Test spec, this compares different leak test methods. What publication/s give guidance on appropriate leak rate limits for different applications/industries.
