DIN ISO 17123-1:2017-09

This part of ISO 17123 gives guidance to provide general rules for evaluating and expressing uncertainty in measurement for use in the specifications of the test procedures of ISO 17123 2, ISO 17123 3, ISO 17123 4, ISO 17123 5, ISO 17123 6, ISO 17123 7 and ISO 17123 8. ISO 17123 2, ISO 17123 3, ISO 17123 4, ISO 17123 5, ISO 17123 6, ISO 17123 7 and ISO 17123 8 specify only field test procedures for geodetic instruments without ensuring traceability in accordance with ISO/IEC Guide 99. For the purpose of ensuring traceability, it is intended that the instrument be calibrated in the testing laboratory in advance. This part of ISO 17123 is a simplified version based on ISO/IEC Guide 983 and deals with the problems related to the specific field of geodetic test measurements.
