BS EN ISO 22282-2 is part of a comprehensive series that covers the full range of field geohydraulic testing methods. The British Standards Institution (BSI) published the entire multi‑part series in 2012 to provide a consistent, best‑practice approach. The six parts of the series are:
The standard outlines specific analytical formulas derived from Darcy’s Law to convert field measurements into the coefficient of permeability ( , measured in meters per second, m/s). The calculation formulas factor in: The geometry of the borehole (radius The intake length of the test section ( The change in head ( ) over a specific time elapsed ( Shape factors (

BS EN ISO 22282-2 is a European Standard for "Geotechnical investigation and testing - Geotechnical design - Part 2: Soil and rock slopes and retaining structures".
Yes. Permeability is essential for predicting contaminant transport. However, for very low permeability clays (k < 10⁻⁹ m/s), you may need additional methods like capillary or vapour tests.

Maintaining a steady water flow and recording the resulting head change over time. Intermediate permeability
The BS EN ISO 22282-2:2012 standard specifies the requirements for determining local water permeability (
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.

After a few clicks, he landed on a webpage that offered the BS EN ISO 22282-2 PDF for download. John was relieved to find that the standard was readily available, and he quickly downloaded it to his computer.
To execute a compliant test, the field kit must meet precise calibration metrics outlined in BS EN ISO 22282-1 and Part 2: Water Permeability Tests in Boreholes | PDF - Scribd
John knew that the product had to comply with the BS EN ISO 22282-2 standard, which specified the requirements for the determination of the tensile strength of geotextiles. He quickly opened his computer and searched for the standard online.
The core purpose of this standard is to standardize the process for determining the local permeability of the ground. Permeability, or hydraulic conductivity, is a measure of how easily water can flow through soil or rock. This standard applies to tests conducted both below and above the groundwater table in an "open hole," meaning a borehole that is not lined with a casing or screen in the test section.
