ISO DIS 18674-2

Description / Abstract: 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).
