Popis:	Intercomparisons were performed between a primary standard gas piston gauge of the Istituto di Metrologia “G. Colonnetti” (IMGC) and two gauges at the National Bureau of Standards. The agreement between the average pressure generated by the IMGC primary standard and the NBS transfer gauge was within 7 ppm (over the range 0.75 to 5.0 MPa) and the agreement between the IMGC primary standard and the NBS primary standard was within 6 ppm (over the range 0.5 to 1.5 MPa). The agreement is well within the estimated uncertainties of the gauges: 24 ppm for the IMGC primary gauge, 30 ppm for the NBS transfer gauge, and 28 ppm for the NBS primary gauge.
