Abstract

Postupak umjeravanja jedan je od osnovnih alata za održavanje mjerne slijedivosti, a time i točnosti i preciznosti uređaja za ispitivanje mehaničkih svojstava. U radu su promatrani rezultati dobiveni prilikom umjeravanja pomoću umjernih utega različitih vrijednosti. U literaturi je prikaz postupaka održavanja mjerne slijedivosti uređaja za mjerenje sile i mase.
U eksperimentalnom dijelu provedena je usporedba rezultata težine zadanih utega mjerenih na vagi te pomoću dinamometra. Utezi su potom iskorišteni za umjeravanje dinamometara po mjernim točkama sukladno normi HRN EN ISO 376:2011. Korišteni su dinamometri vrijednosti od 200, 500 i 1000 N kako bi se dobila bolja rezolucija rezultata pri manjim vrijednostima sile. Analizirani su dobiveni rezultati umjeravanja pomoću utega te su dati određeni zaključci.

Abstract (english)

The calibration procedure is one of the basic tools for maintaining the measurement traceability, and thus the accuracy and precision of devices for testing mechanical properties. The paper observes the results obtained during calibration using weights of different values. The literature presents the procedures for maintaining the measurement traceability of devices for measuring force and mass.
In the experimental part, a comparison of the results of the given weights measured on a scale and with a force transducer was performed. The weights were then used to calibrate the force transducer at measuring points in accordance with the standard HRN EN ISO 376: 2011. 200, 500 and 1000 N force transducers were used to obtain better resolution results at lower force values. The obtained results of weight calibration were analyzed and certain conclusions were given.
