BS EN ISO 22282-1:2012 PDF Download

BS EN ISO 22282-1:2012 is a standard that provides general rules and principles for geohydraulic testing in soil and rock as part of geotechnical investigation and testing services. The standard aims to establish concepts and requirements for permeability measurement in soil and rock.

Geohydraulic testing serves various purposes, including determining the permeability of soil or rock in their natural or treated states, assessing transmissivity and storage coefficient, and determining hydrodynamic parameters of aquifers. It can be used to evaluate the effectiveness of grouting in rock mass, assess seepage and drainage, evaluate groundwater lowering work, and examine the effects of cut-offs for dams, tunnels, and shaft sinking. Geohydraulic testing is also useful for checking the tightness of fill or cover, assessing fluid and suspension flow in the ground, and planning for remedial measures.

BS EN ISO 22282 is composed of several parts, each dealing with specific aspects of geohydraulic testing. These parts include general rules, water permeability tests in a borehole using open systems, water pressure tests in rock, pumping tests, infiltrometer tests, and water permeability tests in a borehole using closed systems. Collectively, these parts provide guidance and standardization for geohydraulic testing methods in geotechnical investigation and testing.
