Summary: A project entitled "Primary Laboratory for Electromagnetic Quantities", financed by the Ministry of Science, Technology and Informatics of the Republic of Croatia, has been carried out in the last two years. Within the given three-year period, activities concerning the establishment of the standards laboratory are being carried out to cover the peak of the accuracy pyramid in the measurement system of the Republic of Croatia. Along with the task of ensuring the measurement traceability through the inclusion of individual standards of the Laboratory into the international measurement system, the project is also intended to achieve the best possible standard basis in the area of electromagnetic measurements. The works on measurements with the ETF balance have been intensified as well as the work on the development of reliable measurement methods and equipment for the need of the National Metrology Service set up according to the directives of the European Community. Fulfilment of the project objectives will provide a support for the National service of certification and quality assurance in manufacturing, traffic and exchange of goods and services. The Laboratory set-up, its equipment and measurement possibilities are described, and guidelines for further activities are being discussed.

Keywords: Absolute Volt determination, National measurement (calibration) laboratory for electromagnetic quantities, Volt and fundamental physical constants

Research goals: Through the proposed investigations it is intended to reach the three basic goals: - to enable, at the international level, the unit Volt with the uncertainty better than 0,1 part per million, to be realised, - to establish the calibration electromagnetic laboratory, as an self-existing accredited state laboratory, leveled to the similar national institutions in the United Europe, and with such authorities in the field of exchanging the goods and services, as to be recognized in this Europe, - to educate the high graduate personals for the future research and realisation of the measurement and control apparatus, standards and methods, measuring devices and transducers, as well as of the progressing theoretical, computational and experimentally-analitical methods of the works in metrology. In the field of determination of the DC voltage in a high accuracy using the Voltage Balance ETF-84. it is first necessary to carry out the measurements with the ETF-84 Voltage Balance using the classical "weighing procedure" in order to obtain the best possible result. The achieved results are to be analyzed in details and presented at the international metrology conferences. The possible systematic errors in these measurements will be also carefully investigated, analyzed and reviewed. After that, it is intended to apply the new measurement procedure "The charge measurement" as to eliminate the systematic errors and to obtain the better measurement results, intending to use them for the future international redefinition of the kilogram.
