11、al Organization for Standardization) is a worldwide federation of national standards bodies ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out throu
12、gh ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collabora
13、tes closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standar
14、ds. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of th
15、is document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 17123-5 was prepared by Technical Committee ISO/TC 172, Optics and photonics, Subcommittee SC 6, Geodetic and surveying instruments. ISO 17123 consists of the followi
16、ng parts, under the general title Optics and optical instruments Field procedures for testing geodetic and surveying instruments: Part 1: Theory Part 2: Levels Part 3: Theodolites Part 4: Electro-optical distance meters (EDM instruments) Part 5: Electronic tacheometers Part 6: Rotating lasers Part 7

18、ANDARD ISO 17123-5:2005(E) ISO 2005 All rights reserved 1 Optics and optical instruments Field procedures for testing geodetic and surveying instruments Part 5: Electronic tacheometers 1 Scope This part of ISO 17123 specifies field procedures to be adopted when determining and evaluating the precisi
19、on (repeatability) of electronic tacheometers (total stations) and their ancillary equipment when used in building and surveying measurements. Primarily, these tests are intended to be field verifications of the suitability of a particular instrument for the immediate task at hand and to satisfy the
20、 requirements of other standards. They are not proposed as tests for acceptance or performance evaluations that are more comprehensive in nature. This part of ISO 17123 can be thought of as one of the first steps in the process of evaluating the uncertainty of measurements (more specifically of meas
21、urands). The uncertainty of a result of a measurement is dependent on a number of factors. These include among others: repeatability, reproducibility (between-day repeatability) and a thorough assessment of all possible error sources, as prescribed by the ISO Guide to the expression of uncertainty i
22、n measurement (GUM). These field procedures have been developed specifically for in situ applications without the need for special ancillary equipment and are purposely designed to minimize atmospheric influences. 2 Normative references The following referenced documents are indispensable for the ap
