ISO/TC 172/SC 6 Geodetic and surveying instruments
International Standard
17.180.30 Optical measuring instruments
ISO 12858-1:2014 specifies the most important requirements of Invar levelling staffs used in geodesy and industry for precise measurement of heights in combination with either an optical-mechanical level equipped with a parallel plate micrometre, or a digital level of comparable precision.
It is applicable to classical staffs with graduation lines and numbering and staffs used in digital levelling with code patterns.
ISO 12858-1:2014 is not applicable to the detailed design and construction of Invar levelling staffs (e.g. materials, handles, fixing points for the struts, fixing of the Invar strip and of the circular level), which may be selected by the manufacturer as appropriate.
