Creation of a National Primary Standard for the Unit of Pressure in the Range of 10-1600 MPa

摘要

The national primary standard GET 43-2013 for the units of pressure in the range of 10-1600 MPa and of the effective area of piston pairs in dead-weight pressure gauges in the range of 0.05-1 cm(2) has been created to upgrade the national primary special standard GET 43-73 for the unit of pressure in the range of 250-1500 MPa. The unexcluded systematic error has been reduced by a factor of 10.
