BS EN ISO 22282-2 an international standard that specifies requirements for determining the local water permeability of soils and rocks in an open borehole . It is a critical component of geotechnical investigation services, aligning with Eurocode 7 (EN 1997-1 and EN 1997-2) to provide data for foundation design, seepage analysis, and dewatering programs. cdn.standards.iteh.ai Core Scope and Objectives This standard deals specifically with open systems , where water is injected into or withdrawn from an isolated section of a borehole without the use of permanent seals or closed-loop pressure monitoring typical of Part 6. It applies to both saturated and unsaturated conditions , above and below the groundwater level. cdn.standards.iteh.ai Primary Test Methods The standard outlines three primary methods based on the expected permeability ( -value) of the ground: standards.iteh.ai Constant Flow Rate Method : Best for high permeabilities ( m/s). It involves maintaining a steady injection or withdrawal rate while recording the change in hydraulic head over time. Variable Head Method : Ideal for intermediate ranges ( 10 to the negative 6 power 10 to the negative 9 power m/s). An instantaneous change in head is produced (e.g., falling or rising head test), and the rate of recovery is measured. Constant Head Method : Suitable for mid-range permeabilities ( 10 to the negative 4 power 10 to the negative 7 power m/s). A constant water level is maintained, and the required flow rate to sustain it is recorded. cdn.standards.iteh.ai Technical Requirements for Execution Test Section Preparation : In non-stable ground, the standard requires perforated tubes, filter material, or open-end tests at the casing base. In stable rock, isolation may involve inflated packers or temporary piezometers. Equipment Accuracy : Water level measurements must be accurate to , and flow rate devices must be accurate within of their measuring range. Unsaturated Soils : The standard provides specific guidance for pre-saturating low-permeability soils (silts/clays) to minimize the effects of suction, which can otherwise lead to unrepresentative results. Data Interpretation : Informative annexes include standard interpretation models such as the Bouwer and Rice Cooper–Bredehoeft–Papadopoulos cdn.standards.iteh.ai Practical Applications The data derived from these tests are essential for: SIST EN ISO 22282-2:2012 - Water Permeability Tests in Boreholes

1. What is BS EN ISO 22282-2? BS EN ISO 22282-2:2012 is the British adoption of the international standard ISO 22282-2:2012 , titled "Geotechnical investigation and testing — Geohydraulic testing — Part 2: Water permeability tests in a borehole using open systems" . It is the second part of the ISO 22282 series, which collectively addresses various geohydraulic testing methods. Purpose and Scope: 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. The key objectives of applying this standard are: bs en iso 22282-2 pdf
To establish baseline groundwater conditions at a site. To determine the hydraulic properties of the ground (e.g., permeability, transmissivity). To gather essential data for the safe and cost-effective design of engineering projects like foundations, slopes, and tunnels.
The information gathered from these tests provides critical insights into foundation stability, potential seepage conditions, and the overall structural integrity of planned engineering works. Context within Eurocode 7: A vital aspect of this standard is its integration with the Eurocodes. It is intended to be used as part of geotechnical investigation services that conform to EN 1997-1 (Eurocode 7 - Part 1: General rules) and EN 1997-2 (Eurocode 7 - Part 2: Ground investigation and testing).
