Abstract

This part of ISO 17123 specifies field procedures to be adopted when determining and evaluating the precision of

levels (spirit levels, compensator levels, digital levels) 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 requirements of other standards. They are not proposed

as tests for acceptance or performance evaluations that are more comprehensive in nature.

This International Standard can be thought of as one of the first steps in the process of evaluating the uncertainty of

a measurement (more specifically a measurand). 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

in 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.
