Clients may request helium leak testing to assess the performance of a material or to analyze or evaluate component longevity. Helium is the preferred leak testing medium because technicians can detect and measure it at minute leak rates (less than 1 cubic centimeter/300 years) and because the gas is inert, meaning it will not react with most components being tested.
