Description
Summary:This report gives the results of the supplementary comparison COOMET.M.P-S1 for measurements of the gauge pressure within the range from 1 MPa to 10 MPa. This comparison was piloted by NSC "Institute of Metrology" (Kharkiv, Ukraine). The principle of comparison is to determine the transfer standard effective area of the piston according to the method of cross-float equilibrium of transfer standard and national standards NMI-participants comparisons piston-cylinder assemblies. All values agree with the reference values within the expanded uncertainties taken with coverage factor k = 2. To reach the main text of this paper, click on Final Report .
