Interlaboratory comparisons are important for the laboratories to assess their own measurement capability. It is equally important for the accreditation bodies and assessors during the audit process of a laboratory to judge whether the laboratory is doing well. As per accreditation rules, it is mandatory for the testing and calibration laboratories to participate in such comparisons from time to time.In this report, results of the bilateral interlaboratory comparison in pressure area in hydraulic media up to 50 MPa gauge between UME (Turkey) and BOM (The FYR of Macedonia) are presented. The artefact used for the comparison was a digital pressure calibrator and its drift was taken into account in the calculation.Results show that all En values lie in acceptable limits.Main text.

The regional supplementary comparison EURAMET.M.P-S13 for pressure measurements in liquid media from 10 MPa to 100 MPa was piloted by the TÜBİTAK UME Pressure Laboratory, Turkey. The transfer standard was a digital pressure gauge, serial number 116321, manufactured by Paroscientific Inc. Eighteen laboratories participated in this comparison. Fourteen laboratories are from EURAMET region; namely UME, MKEH, BoM, DPM, DMDM, MBM, GUM, IMT, HMI/FSB-LPM, VSL, VTT MIKES, FORCE Technology, IMBIH, NSAI NML. VMC is from COOMET and QAF, EMI, SASO NMCC are from GULFMET region. Main text To reach the main text of this paper, click on Final Report.
