Pressure Intercomparison in Gas Medium Organized by HMI/FSB-LPM and CROLAB KUL

This paper presents results of the interlaboratory comparison organized by CROLAB-KUL (Calibration Laboratories Club) and Laboratory for Process Measurements (LPM) which is Croatian National Pressure Laboratory and part of Croatian Metrology Institute (HMI). Comparison was performed according to DKD-R6-1 (Type B) procedure for gas pressure measurements in the range from 0 up to 2 MPa using pressure transducer of high accuracy as transfer standard. Participating laboratories were: MARUS ATM d.o.o. ; Metron Instruments d.o.o., Ravnoteža, Petrokemija d.d., Inspekt Metrolab, BMB, CEI-IETA, STSI, all accredited by Croatian Accreditation Agency (HAA). Participants have reported deviations and measurement uncertainties in nine calibration points. Analysis of the measurement results are given by calculating the deviation, En, normalized with respect to the stated uncertainty for each participating laboratory.
