BS EN ISO 22282-3:2012 PDF Download

BS EN ISO 22282-3:2012 is a standard that specifies the requirements for water pressure tests carried out in boreholes drilled into rock as part of geotechnical investigation and testing. These tests are used to investigate various properties of the rock mass, including its hydraulic properties, absorption capacity, tightness, effectiveness of grouting, and geomechanical behavior.

The standard acknowledges that the effects of the geohydraulic tests are not only influenced by the ground itself, but also by the testing procedure. It recognizes that historically, the tests were evaluated based on the assumption of stationary behavior, but recent advances in geohydraulics have shown that transient phenomena are often present. Therefore, the standard aims to address the limitations of certain testing procedures while not overly restricting the required equipment.

BS EN ISO 22282-3:2012 is part of a series of standards under the general title Geotechnical investigation and testing - Geohydraulic testing. Other parts of the series include general rules, water permeability tests in a borehole using open systems, pumping tests, infiltrometer tests, and water permeability tests in a borehole using closed systems. These standards provide a comprehensive framework for geohydraulic testing in geotechnical investigations.
