DIN ISO 17123-1
Optics and optical instruments - Field procedures for testing geodetic and surveying instruments - Part 1: Theory (ISO 17123-1:2014)

Title (German)

Optik und optische Instrumente - Feldprüfverfahren geodätischer Instrumente - Teil 1: Theorie (ISO 17123-1:2014)

Overview

This Part 1 of ISO 17123 gives guidance with the aim of providing general rules for the evaluation and expression of measurement uncertainty for use in the specification of test methods according to ISO 17123-2 to -8. ISO 17123-2 to -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 98-3 and deals with the problems related to the specific field of geodetic test measurements. This standard differs from DIN 18723-1:1990-07 as follows: a) the contents have been made substantially more detailed. For instance, the standard in its overall concept considers further aspects such as arbitrary interferences, general functional relationships with the target value, correlations and different distributions and the summary of different influencing factors; b) this standard uses the concept of determining uncertainty components (Type A and Type B) in accordance with ISO/IEC Guide 98-3:2008, Uncertainty of measurement - Part 3: Guide to the expression of uncertainty in measurement (GUM:1995), and uses letter symbols according to GUM; c) this standard defines terms of measured quantity values and measurement uncertainty; d) several sample calculations have been included in this standard. The committee NA 005-03-04 AA "Geodätische Instrumente und Geräte (SpA zu ISO/TC 172/SC 6)" ("Geodetic instruments and devices (mirror committee to SpA to ISO/TC 172/SC 6)") at DIN is responsible for this standard.
