2. Pressure calibration
2.1 Object
The purpose of calibration is to ensure the connection of a pressure standard to national references. From a practical point of view, a calibration chain is set up to meet the final requirement, which is the calibration of the instrument used to carry out a pressure measurement in a manufacturing process, or on a test facility, for example. This calibration chain can be represented as a pyramid, with the national reference at the top and all the instruments connected to it at the base.
The apex of the pyramid is the primary standard, which materializes the pressure unit from the fundamental quantities of the SI system. This primary standard is used to define, by extrapolation, the national references that materialize the unit over the entire pressure...
