This European Standard describes the calibration of those leaks that are used for the adjustment of leak detectors and the determination of leakage rate in everyday use. The preferred calibration method in this case is a comparison with a standard leak. In this way the leaks used for routine use become traceable to a primary standard as the ISO 9000 series of standards require.
