Abstract:
Proficiency testing is an important way of meeting the requirements of ISO/IEC 17025 in the area of quality assurance of laboratory results. Laboratory for dimensional measuring technique on Mechanical Engineering Faculty participated in comparison of dial gauge and external micrometer. The key requirements of such comparisons are that the samples are same or similar, and also thatthe set of samples measured are appropriate to test and display similarities and differences in results. A proficiency testing scheme is a system for objectively evaluating laboratory results by external means, and includes regular comparison of a laboratory's results at intervals with those of other laboratories. The main objective of a proficiency testing scheme is to help the participating laboratory to assess the accuracy of its test results. Regular participation in a proficiency testing scheme provides independent verification of measurement capability of a laboratory and shows a commitment to a maintenance and improvementof performance. Participants were three laboratories from Bosnia and Herzegovina and one pilot laboratory wasfrom Norway. Included laboratories calibrated the instruments using their own procedures and issue their standard calibration certificates according to their accreditation scope. Circulation of testing instruments was from pilot laboratory to the participating laboratories one by one and again to the pilot laboratory for checking. The values compared were: fmax for external micrometer and fe, fges and fu for dial gauge.
