DIN EN ISO 18674-2:2015-08

This Standard applies to the measurement of displacements along a line by means of extensometers carried out for geotechnical monitoring. It is to be applied in conjunction with EN ISO 22474-1. Specifically, this Standard applies to - investigating soils and rocks; - checking geotechnical design values in connection with the Observational Design method; - deriving geotechnical design values (e. g. pile load test; trial tunnelling); - evaluating stability ahead of, during or after construction (e. g. natural slopes, slope cuts, embankments, excavation walls, foundations, dams, refuse dumps, tunnels).
