Ruler is probably one of the most widely used length measuring instrument in the world. For laboratories that plan to be accredited for the calibration of Ruler, the acquisition of a specialized Measuring bench is not economically feasible. Confidence in the measured result depends on the measurement uncertainty, and where deficiencies are observed, the values that contribute to the measurement uncertainty should be investigated. This paper describes an interlaboratory comparison for a small number of laboratories on the example of a Measuring bench for calibrating Ruler and indicates the procedure for problem identification; diagnosis of causes; consideration of solutions; initiation of action for improvement and monitoring of the results of applied solutions. The authors documented the problem and listed the elements that contributed to "Unsatisfactory" result in interlaboratory comparisons. They described the actions they took to overcome the "Unsatisfactory" result, analyzed whether the proposed solutions led to "Satisfactory" result and took actions accordingly. The paper presents the results of the international interlaboratory comparison, which are a confirmation of the competence of the personnel, measuring calibration equipment and calibration methodMetode vrednotenja rezultatov medlaboratorijske primerjave so predpisane s standardi ISO. Ravnilo je verjetno eden izmed najbolj uporabljanih dolžinskih merilnih instrumentov na svetu. Za laboratorije, ki želijo biti akreditirani za umerjanje ravnila, pridobitev specializirane merilne mize ni ekonomsko smiselna. Zaupanje v izmerjeni rezultat je odvisno od merilne negotovosti, kjer pa se opazijo pomanjkljivosti, je treba raziskati vrednosti, ki prispevajo k merilni negotovosti. V tem prispevku je opisana medlaboratorijska primerjava za majhno število laboratorijev na primeru merilne klopi za umerjanje ravnila, opisan je postopek za identifikacijo morebitnih težav in diagnostika vzrokov; upoštevanje rešitev; začetek ukrepanja za izboljšanje in spremljanje rezultatov uporabnih rešitev. Avtorji so dokumentirali težavo in našteli elemente, ki so prispevali h končni oceni medlaboratorijskih primerjav »nezadovoljivo«. Opisali so ukrepe, ki so jih predvideli za izboljšanje rezultata »nezadovoljivo«, analizirali, ali so predlagane rešitve prispševale k oceni »zadovoljivo«, in sprejeli ustrezne ukrepe. V prispevku so predstavljeni rezultati mednarodne medlaboratorijske primerjave, ki pričajo o usposobljenosti osebja, ustreznosti merilne kalibracijske opreme in metode kalibracijeTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaZveza geodetov Slovenije
