Abstract

U okviru ovog rada provedena je međulaboratorijska usporedba. U usporedbi su sudjelovala
tri laboratorija: Laboratorij za procesna mjerenja (LPM) Fakulteta strojarstva i brodogradnje,
laboratoriji EkoVent-a i laboratorij Klimaopreme. Opisuje se provedba umjeravanja i konačno
usporedba rezultata umjeravanja u području malih tlakova do 100 Pa, a kao umjeravani uređaj
koristio se Halstrup Walcher, KAL 200. Prije samog opisa provedenog mjerenja, dan je
pregled osnovnih metoda za mjerenje niskih tlakova, te su objašnjeni postupci umjeravanja
manometara. Navedene su i detaljno opisane osnovne upute i norme za provođenje
međulaboratorijskih usporedbi, od kojih su za ovaj rad i ovo umjeravanje najznačajnije
metode (norme) i upute dane od strane DKD-a. Glavna svrha cijelog rada je određivanje
vrijednosti faktora slaganja En temeljem kojeg se vršila procjena kvalitete međulaboratorijske
usporedbe.

Abstract (english)

An inter-laboratory comparison has been conducted in this paper. Three laboratories
participated: the Laboratory for Process Measurements (LPM) of the Faculty of Mechanical
Engineering and Naval Architecture, EkoVent Laboratory and Klimaoprema Laboratory. The
implementation of calibration and the final comparison of calibration results of small
pressures in the range of up to 100 Pa are described, while Halstrup Walcher, KAL 200, was
used as a measured device. Before the description of the measurement, basic methods for
measuring low pressures are presented, and procedures for calibration of manometers are
explained. Basic instructions and norms for conducting inter-laboratory comparisons are
described, of which the most important methods (norms) and instructions are given by the
DKD. The main purpose of the paper is to determine the value of the agreement factor En,
which served as the basis for the estimation of the inter-laboratory comparison.
