Every National Metrology Institute (NMI) is obliged to keep the national etalon of measurement standards for the legal units of measurement according to the SI units, to ensure its international comparability and recognition, and to make the units of measurement available for business and industry by calibration of reference and working standards. For the purpose of the realization of the unit 'Newton' a system has been developed and implemented in several comprehensive projects, which derives the unit of force directly from the mass. In the beginning of this dissertation general and specific requirements and conditions are described, which are necessary for the creation of a Deadloadmachine in the range from N to MN as a primary system and national standard. A comparison of the requirements with existing systems shows a series of contradictory problems. An analysis of the requirements enables gradually the preparation of a detailed catalogue of requirements. To resolve the discrepancies in the requirements, methods and solutions have been developed, which, compared to existing realization possibilities, contain modifications and represent further developments. Based on the conversion of the developed catalogue of requirements a concept for the realization of such a system has been prepared. Systematically all contributions to the measurement uncertainty have been regarded and analysed. From this point of view the limit of the technical possibility has been detected. These possibilities have been analysed, developed and a concept for the implementation has been derived from these solutions. Thus, related to the size of the machine, a remarkable improvement in the measurement range and also the obtained accuracy of the results of measurement was reached. In cooperation between the Federal Office of Metrology and Surveying (BEV) and the Institute for Production Engineering (IFT) of the University of Technology in Vienna, the final concept has been realized as a primary force standard for the BEV as the Austrian National Metrology Institute. Based on this primary force standard and with the necessity to provide the international recognition of the measurement results, in this dissertation a method has been defined, the procedure has been carried out and has been documented, which provides the necessary basis for this international recognition. The developed extensions and solutions are described in an extensive documentation and they are proved by a series of measurements. The verification of provided product requirement specifications, its validation to the operational fitness and the proof of the well controlled process carried out by measurements are the basis of this paper. It is shown in detail, how in conventional and equivalent systems occurring disturbances are compensated, so that it is possible to work without considering these disturbances, as they are regulated by international calibration guidelines for the evaluation and the associated measurement uncertainty analysis. By means of numerous tests this methodology of comparisons was presented and demonstrated. Thus the furnishing proof verification was performed, which is accepted in Metrology. The central part of this argumentation consists of comparative measurements carried out within the framework of a scientific cooperation with the Physikalisch Technische Bundesanstalt (PTB). By measuring the transfer standards of the PTB the traceability of the system has been achieved by resorting to the national standard of the force of the PTB. These measurements form the base of the validation of this system and the entire process for the realization of the force in the BEV, and are thus the necessary evidence of the process control. By compilation and interpretation of the measurement results the process capability and suitability of the new system are documented and its measurement capabilities are proved. This proof is the basis of the international acknowledgment of the measurement results as given by the CIPM MRA (CIPM Mutual Recognition Arrangement) and the certificates issued by the BEV, and thus the purpose of the thesis has been achieved by proving that this method of validation is correct.
