Abstract
Cilj ovog rada je pokazati osiguranje kvalitete rezultata umjeravanja mjerila tlaka do 2 MPa (20 bar) koje je osmišljeno provodeći međulaboratorijsku usporedbu. Prvi dio rada obuhvatio je pregled normi i smjernica za provedbu međulaboratorijskih usporedbi, uključujući statističke metode za procjenu rezultata umjeravanja. Također, objašnjen je postupak umjeravanja prema metodi B iz DKD-R 6-1 uputa koja se koristila u svim laboratorijskim mjerenjima, te je prikazana osnovna jednadžba za izračun efektivnog tlaka tlačne vage uz primjenu određenih korekcija. Eksperimentalni dio rada proveden je u Laboratoriju za procesna mjerenja Fakulteta strojarstva i brodogradnje u Zagrebu. Koristeći postojeće etalone sastavljena je i opisana mjerna linija za umjeravanje mjerila tlaka. Odabrani prijenosni etalon za međulaboratorijske usporedbe, pretvornik tlaka FLUKE 2700G, umjeren je na etalonskom sustavu i dostavljen u četiri laboratorija koja su sudjelovala u međulaboratorijskoj usporedbi: FSB-LPM – koordinator usporedbe, LAB 1 (ARDENTER), LAB 2 (Endress+Hauser) i LAB 3 (ostao anoniman zbog privatnosti podataka). Kriterij za prihvatljivost rezultata umjeravanja bio je izračunata E_n vrijednost, a rezultati su prikazani tablično i grafički za sve točke usporedbe.
Abstract (english)
The aim of this paper is to demonstrate quality assurance of pressure gauge calibration results up to 2 MPa (20 bar) designed through interlaboratory comparison. The first part of the paper encompassed a review of standards and guidelines for conducting interlaboratory comparisons, including statistical methods for evaluating calibration results. Also, the calibration procedure according to method B from DKD-R 6-1 guidelines, which was used in all laboratory measurements, was explained, and the basic equation for calculating the effective pressure of the pressure balance with the application of certain corrections was presented. The experimental part of the paper was conducted at the Laboratory for Process Measurements of the Faculty of Mechanical Engineering and Naval Architecture in Zagreb. Using existing standards, a measurement line for calibrating pressure gauges was assembled and described. The selected transfer standard for interlaboratory comparisons, the FLUKE 2700G pressure gauge, was calibrated on the standard system and delivered to four laboratories that participated in the interlaboratory comparison: FSB-LPM as a coordinator, LAB 1 (ARDENTER), LAB 2 (Endress+Hauser) and LAB 3 (remained anonymous for data privacy reasons). The criterion for result acceptability was the calculated E_n value, and the results were presented in tables and graphs for all comparison points.
