Formulas used for the Conversion of Moisture Values
These formulas come from General Eastern documentation.
The leak testing of sealed packages, when the initial atmosphere in the enclosure had some helium, became a common practice by the early nineteen sixties. In 1965 D.A. Howl and C.A. Mann reported on a leak testing method for enclosures which were not sealed in an atmosphere containing helium. This new method forced helium under pressure through the leakage path into the enclosure. A helium mass spectrometer then detected the helium escaping the enclosure. Subsequently, MIL-STD 883 adopted a leak test method based on this work.
