Helium Fine Leak Hermeticity Testing

Helium hermeticity testing is used to verify the seal process of a hermetic device. Devices are typically preconditioned in a pressurized chamber and, after the required conditions are met, the leak rate is measured and recorded, applying pass/fail criteria. ORS holds DLA Laboratory suitability in the seal test methods defined in Mil-Std 883 method 1014 condition A1 and A2, Mil-Std 750 method 1071 condition H1, H2 and H3 and Mil-Std 202 Method 112 condition C. Testing is also performed per Telcordia GR1221-CORE and GR-468-CORE for passive and active devices.

Helium hermeticity testing can be modified to suit the testing requirements of your device. We have assisted many clients in creating a custom leak test plan based on their needs. ORS also provides open face leak testing and leak site identification.

Expanded Fine Leak for Other Gases and Compounds
Specialized leak testing is available for determining leak rates for gases other than helium. Leak rates of various gases (i.e. Argon, CO2, Acetic Acid, Ethylene Glycol, etc.) may be measured at low leak rates utilizing a specialized mass spectrometer tuned for the particular substance of interest. Applicable standards are normally available in a wide range of leak rates.
