This standard establis es the methods and means for the verification of manometers, vacuum gauges and manovacuometers of elastic deformation, recorders that are used for the direct measurement and recording, with respect to time, of depressions and overpressures, with a measurement interval from :
——0.1 to 0 MPa (- 1 to 0 kgf/cm2) up to: 0 to 160 MPa (0 to S 600 kgf/cm2) class 0.6 to 2.5. This standard also applies to the aforementioned instruments that have an additional indicating device.
