Vacuum gauges. Calibration by direct comparison with a reference gauge1 Scope This International Standard specifies the physical, technical and metrological conditions to be fulfilled when calibrations of vacuum gauges are performed by direct comparison with a reference gauge. From the conditions described, the design of an apparatus that can perform vacuum gauge calibrations in an adequate manner can be deduced. The vacuum gauges to be calibrated can be of any kind. Many types of gauges consist of several parts.
