Abstract (Croatian)
Laboratorij za precizna mjerenja dužina koji je ujedno i Nacionalni laboratorij za duljinu sudjeluje (Laboratorij) CIPM MRA (Comité International des Poids et Mesures, Mutual Recognition Arrangement) ključnim usporedbama etalona duljine među kojima su od posebnog značaja i precizne mjerne skale. U usporedbenim mjerenjima pri iskazivanju rezultata mjerenja, neophodno je dati i procjenu mjerne nesigurnosti. U novije vrijeme, Monte Carlo simulacije (MCS) imaju sve veću primjenu u procjeni mjernih nesigurnosti. U radu se prezentira validacija realizirane mjerne nesigurnosti GUM metodom upotrebom MCS metode. MCS metoda temelji se na generiranju slučajnih brojeva iz funkcija gustoće vjerojatnosti za svaku ulaznu veličinu i stvaranju eksperimentalne funkcije gustoće vjerojatnosti izlazne veličine kombinirajući različite razdiobe kojima su definirane ulazne veličine. Isto tako, u radu se prezentiraju rezultati međunarodnog usporedbenog mjerenja koji predstavljaju stvarnu validaciju mjernog uređaja i procijenjene mjerne nesigurnosti.
Abstract
The Laboratory for Precise Measurement of Length, which is at the same time the Croatian National Laboratory for Length (in text Laboratory) takes part in CIPMMRA(Comité International des Poids et Mesures, Mutual Recognition Arrangement) comparisons of length standards, which include line scales as very important standards of length.When the results reported in the comparisons, it is necessary to state the estimated measurement uncertainty. Recently, the Monte Carlo simulations (MCS) have been increasingly applied in the field of estimation measurement uncertainties. The paper presents validation of the realised measurement uncertainty by GUM method in process of precise line scales calibration using the MCS method. The MCS method is based on random number generation from the probability density functions for each input value and forming of experimental probability density function of the output value. Also, the paper presents obtained results of the international comparison measurement which representing a real validation of the device and evaluated measurement uncertainty.
