Projekta Nr.ISO 17123-3:2001
Nosaukums<p>This part of ISO 17123 specifies field procedures to be adopted when determining and evaluating the precision (repeatability)</p> <p>of theodolites and their ancillary equipment when used in building and surveying measurements. Primarily,</p> <p>these tests are intended to be field verifications of the suitability of a particular instrument for the immediate task</p> <p>at hand and to satisfy the requirements of other standards. They are not proposed as tests for acceptance or performance</p> <p>evaluations that are more comprehensive in nature.</p> <p>This part of ISO 17123 can be thought of as one of the first steps in the process of evaluating the uncertainty of a</p> <p>measurement (more specifically a measurand). The uncertainty of a result of a measurement is dependent on a</p> <p>number of factors. These include among others: repeatability (precision), reproducibility (between day repeatability),</p> <p>traceability (an unbroken chain to national standards) and a thorough assessment of all possible error sources, as</p> <p>prescribed by the ISO Guide to the expression of uncertainty in measurement (GUM).</p> <p>These field procedures have been developed specifically for in situ applications without the need for special ancillary</p> <p>equipment and are purposefully designed to minimize atmospheric influences.</p>
