Abstract
U radu je opisano kako se mjerenje razvijalo kroz povijest, pojašnjeno je što znači mjeriti, važnost i značaj mjerenja u svim granama znanosti, a i u životu općenito. Definirane su osnovne mjerne jedinice, predmeci za pisanje mjernih jedinica. Nadalje su pojašnjene međunarodne, nacionalne, regionalne metrološke infrastrukture, njihovi ciljevi, kako se provodi mjeriteljstvo i koji organi provode isto. Objašnjena je i mjerna sljedivost, kako se provodi, koji su ciljevi, ustanove koje ju provode. Pojašnjeno je kako valjano iskazati rezultat mjerenja, izračunati mjernu nesigurnost, teorijski i pokusom. Mikrometrom su mjerene debljine triju ispitnih pločica, 20 puta na različitim mjestima i na temelju izmjerenih podataka izračunate su mjerne nesigurnosti, Nalimovim testom se provjeravalo koji su rezultati pouzdani, a koji nepouzdani, tj. koji se prihvaćaju, a koji odbacuju. Nikada se mjerenjem ne može dobiti 100% - tna sigurnost, uvijek postoje barem mala odstupanja od prave mjerene vrijednosti, zato su tu tolerancije koje dopuštaju određena odstupanja.
Abstract (english)
This paper presents development of measuring through the history, it explains what measuring means, importance and significance of measuring in all branches of science and in life in general. Set of base units, prefixes and derived units are defined, too. Paper explains worldwide metrology, national metrology institutes, regional metrology organizations, theirs requirements, how measurement are carried out and which organs work on it. Paper presents how to properly express measurement result, how to calculate measurement uncertainty, by theory and by the experiment. Thickness of the plate was measured by micrometer, 20 times on different places and based on measurement results measurement uncertainty was calculated. Nalim's test present which results are reliable and which are unreliable ie which are accepted, which aren't accepted. Measurement can not be performed by 100% certainty, there is always at least a small deviation from the true measured values, so there are tolerances that allow certain deviations.
