|Title:||Results of a hydraulic pressure comparison in the range from 25 MPa to 200 MPa between NIS-Egypt and NIST-USA|
|Published:||February 28, 2012|
|Abstract:||The results of an informal pressure comparison between the National Institute of Standards and Technology (NIST), USA, and the National Institute of Standards (NIS), Egypt, are presented. The comparison was aimed to determine degree of equivalence between NIST and NIS in the pressure range from 25 MPa to 200 MPa at a reference temperature of 20 °C. The comparison used a transfer standard (TS) which was a piston-cylinder assembly (PCA) of 4.9 mm2 nominal effective area. The results of the comparison show agreement between the laboratory results to within their claimed standard (k=1) uncertainties.|
