BS EN ISO 22282-2 is a crucial European standard adopted from the international ISO framework. It specifies the requirements for performing field permeability tests by the open hole method (also known as slug tests or bailer tests) in soils and rock. This part of the ISO 22282 series focuses on tests conducted in a single borehole without packers, providing essential data for hydrogeological and geotechnical projects.
is the definitive international standard governing water permeability tests in boreholes using open systems . As an integral component of geohydraulic field testing under Eurocode 7 (EN 1997-1 and EN 1997-2), this standard outlines the mandatory procedures, equipment accuracy, and analytical methods required to measure local hydraulic conductivity ( ) in soils and rocks.
BS EN ISO 22282-2 has been employed on some of the most significant infrastructure projects in recent years. It is the standard for professional geotechnical and hydrogeological consultancies.
m/s), involving an instantaneous change in water level followed by a measurement of its recovery over time. Constant Head Method : Suited for lower permeability ranges ( 10 to the negative 4 power 10 to the negative 7 power
The standard primarily covers tests performed in an "open" system. Unlike packer tests (covered in Part 4), these are usually simpler to execute but require precise measurement of water levels over time. 1. Constant Head Test

An open system is one where the test section of the borehole is directly open to the atmosphere. Typically, this involves creating a "test zone" within the borehole, often isolated by inflatable packers (seals), to which water is added, and the rate at which this water flows out into the surrounding soil or rock is measured. As the name implies, the test zone remains open and accessible above ground.
In the field of geotechnical engineering, understanding the permeability of soil and rock is fundamental to designing foundations, slopes, earth dams, and dewatering systems. The British Standard is part of a multi-part European adoption of the international standard (ISO) that specifically addresses in-situ permeability testing.
A useful feature of BS EN ISO 22282-2 is its comprehensive standardization of water permeability tests in boreholes using open systems
is a crucial technical standard for professionals in geotechnical engineering, hydrogeology, and civil construction. It provides the definitive requirements for determining the local permeability of soils and rocks by conducting water permeability tests in an open borehole.
For geotechnical engineers, site investigators, and construction specialists, obtaining accurate, reliable data on ground permeability is crucial. is the key international standard governing water permeability tests in boreholes using open systems.

Layered soils, fractured rock masses, and determining the permeability of specific strata.
Includes requirements for filter packs, perforated tubes, and the preparation of test sections in both stable and unstable ground. 📝 Reporting Requirements INTERNATIONAL STANDARD ISO 22282-2
It was a typical Monday morning for John, a quality assurance manager at a leading geosynthetic manufacturing company in the UK. As he sipped his coffee, he began to review the company's product development pipeline. One of the projects that caught his attention was the development of a new geotextile product, which was required to meet specific international standards.
