Annotation of standard text ISO 12858-3:2005 :
Description / Abstract: ISO 12858-3:2005 specifies the most important requirements of tribrachs used in geodesy for the connection of the instruments body with its base. The requirements in ISO 12858-3:2005, however, do not guarantee the full interchangeability of the instruments body with tribrachs of different manufacturers, but give the detailed specifications of the clamp system to ensure the reliable mounting and clamping without prejudicing their performance and their usefulness. There are mainly two types of tribrachs in use, categorized in ISO 12858-3:2005 as Types W and Z. ISO 12858-3:2005 is applicable to tribrachs which are used for levels, theodolites, tacheometers, GPS equipment, EDM instruments and in combination with targets, reflectors, antennae etc.
