Fine leak is performed using suitable pressure and vacuum chambers and a mass-spectrometer-type leak detector calibrated for helium. Samples are placed in a sealed chamber pressurized with pure helium. What is a fine leak test? Fine & Gross Leak / Electrical Test Also referred to as Seal or Hermeticity Test, this test verifies that the hermetic seal of a component is intact and typically follows trim and form and/or RHSD of a glass seal device.
