Sažetak
The paper offers an overview of international and Croatian norms necessary in testing, calibration and indication of measuring uncertainty for geodetic instruments. The Act on Measurement (NN 2003b, NN 2007) emphasizes the importance of maintaining the state standards, their comparison with international standards, as well as the testing, verification and monitoring of instruments. On the basis of the Act mentioned above there have been two Order (NN 2003a, NN 2005) passed by the Croatian Standards Institute. In these Orders there are all instruments listed, including geodetic instruments and equipment that have to be tested and calibrated periodically for the purpose of defining their correctness and estimating the measuring uncertainty of measurement results. All errors are given that influence the measurement of horizontal and vertical angles with theodolite. The procedure of testing the measurement precision of horizontal and vertical angles with theodolite according to the norm HRN ISO 17123-3:2004 (HRN ISO 2004) is described in details. For the purpose of testing the theodolite precision according to this norm there was the programme Teodolit_ISO created.
