The standard defines the procedures for measuring the hydraulic conductivity of soil and rock. Unlike Part 3 (which covers pressure tests in closed systems like packers), Part 2 focuses on open systems
This method is used when the test section is at the very bottom of an uncased borehole. Water is forced into or removed from the formation through the open end of the drilling string. Common procedures include: bs en iso 22282-2 pdf
Layered soils, fractured rock masses, and determining the permeability of specific strata. The standard defines the procedures for measuring the
Incorrect permeability data can lead to: also known as "open systems
: Devices must be accurate to within 0.01 meters .
BS EN ISO 22282-2:2012 defines procedures for measuring water permeability in soils and rocks via borehole open systems, supporting Eurocode 7 geotechnical site investigations. The standard covers techniques for assessing groundwater flow in foundation design and environmental assessments, replacing parts of BS 5930. For official access, you can find the full document on the BSI Knowledge portal or the ISO Online Browsing Platform .
The standard specifies the requirements for determining local water permeability in soils and rocks both above and below the groundwater level . It focuses specifically on geohydraulic tests conducted in open boreholes, also known as "open systems," which do not use packers to isolate test sections. Key Content of the Standard
