Interlaboratory comparison in the pressure range from 0 to 2 MPa for accredited calibration laboratories

摘要

This paper describes procedure and results of the interlaboratory comparison that was organised by Croatian national pressure laboratory (HMI/FSB-LPM) between eight accredited pressure calibration laboratories. Comparison was performed in the gauge pressure range from 0 to 2 MPa with pressure transducer as transfer standard and using gas as transmitting medium. Basic aim of this comparison was to improve measurement methods and the measurement uncertainties of each participating laboratory. Analysis of the measurement results are given by calculating the deviation, iEi/subini/sub/, normalized with respect to the stated measurement uncertainties.
