MS ISO 17123-2:2001 Optics and optical instruments – Field procedures for testing geodetic and surveying instruments – Part 2: Levels

Scope:
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.
