    maximum allowable permeation rates. Any leak rate that is higher than the maximum allowable permeation rate is consider a leak. Typical maximum allowable permeation rates range in the 10-2 mbar l/s decade. However, manufacturers often achieve permeation rates of about ten times lower permeation, i.e. in the 10-3 mbar l/s range. Hence, leak rate limits are set in the 10-3 10-2 mbar l/s

  • Fundamentals of leak detection - Leybold

    The leak rate of a vessel indicates the amount of gas flow which escapes through the walls of the vessel. It must be noted, however, that the leak rate for a leak depends on the type of gas. If the gas temperature T and the molar mass M of a gas G is known, the gas mass flow can be calculated from the leak rate
