The Definitive Guide to BS EN ISO 22282-2: Water Permeability Tests in a Borehole

In geotechnical engineering and environmental site investigations, understanding the hydraulic conductivity of soil and rock is critical. is the internationally recognized standard that defines the parameters, equipment, and procedures for measuring water permeability below the groundwater table using borehole tests.

: An open system indicates that the water level changes or remains controlled through a borehole casing or screen without sealing the top zone with a pneumatic packer. bs en iso 22282-2 pdf

For environmental impact assessments or civil litigations involving water table disruptions, data collected via a recognized BS EN ISO framework holds legal and professional weight. Safety in Construction

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 22282-2:2012 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 . : Planning the removal of groundwater during construction

Assessing the stability of foundations, shear strength, and seepage conditions.

Applicable to tests conducted both above and below the groundwater table. Purpose: To determine the local permeability coefficient (

– it must be used in conjunction with BS EN ISO 22282-1 (General requirements). : An open system indicates that the water

: Record time, water levels, and flow rates at tight intervals initially, expanding the intervals as the system stabilizes.

For constant head : Initiate flow and adjust the valve until the water level locks into a steady position.

To comply with UK regulations (post-Brexit, the “BS EN” designation remains valid), engineers must purchase the official PDF from BSI or an authorized reseller. Using the official document guarantees access to full annexes, calculation examples, and critical notes on equipment calibration that are often omitted from unauthorized copies.
