Summary: Contemporary knowledge in the world shows the necessity of the national measurement laboratories activity. The scientific basis for the establishment of the National measurement laboratory in the Republic of Croatia, with duty to improve measurement of length, angle and surface roughness, calibration of secondary and working standards, as well as measures for the mentioned quantities, has been mostly built by this project. In that sense, for a term of the last five years, attention has been mostly consecrated to work out the scientific studies about uncertainties of measurements (theoretical working out and experimental verification) with the purpose of assuring traceability to primary standards. Measurement possibilities of the Laboratory for precise length measurements on the Faculty of the Mechanical engineering and Naval architecture (LFSB), exactly about achievable uncertainties of measurements for the quantities length, angle and roughness, which are determined on the basis of performed comparison measurements with primary laboratory (Istituto di metrologia "G.Colonetti", Turin). With this goal on mind measurement conditions in the LFSB were improved, specially in consideration of working out and using a system for automatically supervising the temperature in the 16 carefully chosen places in the laboratory. At the end of the year 1994., LFSB received the accreditation from SIT (Servicio di taratura in Italia) for the field of roughness, and for the field of length procedure is in progress. Improving measurement methods, making comprehensive documentation LFSB (Proceedings of quality, Procedures for caring out metrological confirmation, General documents), and congruently to the European standard EN 45001, which has been announced by sit experts, had gone before mentioned acknowledgment. With received acknowledgment LFSB realized connection with European and world-wide measurement system, because SIT is one of subscribers of Multilateral arrangement of the European association for accreditation of the laboratories (EAL) for mutually acknowledgment of the metrological confirmation certificate. In this connection, it is necessary to underline that the biggest profit from the realized results of this project gains Croatian economy, specially in a offered possibility of acquisition of the formal and real conditions, in this segment, for gaining certificate congruently to the series of the international standards ISO 9000.

Keywords: national metrological laboratory, length, angle, roughness, calibration system, measuring uncertainty, comparative measurements

Research goals: Four basic aims with this scientific research has been put: 1. To achieve the world level keeping of standards of predictable measuring units (length, angle and roughness parameters) and their transmission with the least possible measuring uncertainty. 2. To establish scientific and material conditions for the Laboratory for precise length measurements on the Faculty of the Mechanical engineering and Naval architecture (LFSB) to be the bearer of length, angle and roughness parameters primary standards to achieve, first of all, the authority from the international measuring institutions 3. To work out the scientific foundations for the establishment of Croatian metrological system for mentioned quantities with possibility of metrological confirmation of certain standards as well as measuring instruments for industrial needs. 4. To educate the high skilled staff to have a dominant influence in development, maintenance and improvement of Croatian metrological unity.
