ISO 17123-1:2010
Optics and optical instruments — Field procedures for testing geodetic and surveying instruments — Part 1: Theory
ISO 17123-1:2010 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.
ISO 17123-1:2010 is a simplified version based on ISO/IEC Guide 98‑3 and deals with the problems related to the specific field of geodetic test measurements.
