| dc.description | As part of a wide-ranging key comparison organized by the Consultative Committee for Mass and Related Quantities (CCM) of the Comité International des Poids et Mesures, this report gives the results of a comparison of pressure measurements in the range 0.05 MPa to 1 MPa. The two transfer standards used were pressure balances equipped with large (10 cm<sup>2</sup>) effective area piston-cylinder assemblies. The scope of the comparison covered the observation of the behaviour of both piston and cylinder assemblies from two manufacturers and made from different materials. The results show agreement of all the laboratory standards within the estimated expanded uncertainties, expressed with a coverage factor k = 2. Most of the difference values (47 out of 54) are inside the standard uncertainties. These results demonstrate the coherency of the standards of the participating laboratories in the range 100 kPa to 1000 kPa for gas pressure, gauge mode. |
