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

This paper describes procedure and results of the interlaboratory comparison that was organised by the Croatian national pressure laboratory (HMI/FSB-LPM) between eight accredited Croatian 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 will be given by calculating the deviation, En, normalized with respect to the stated measurement uncertainties.
