BS EN ISO 22282-2:2012 is the British implementation of the international standard for geotechnical investigation and geohydraulic testing, specifically focusing on water permeability tests in a borehole using open systems. Core Purpose and Scope
Objective: It specifies requirements for determining the local permeability of soil and rock both above and below the groundwater level.
Application: The standard is part of geotechnical investigation services performed in accordance with EN 1997-1 and EN 1997-2 (Eurocode 7).
Current Status: The 2012 version remains current and was last reviewed and confirmed by the International Organization for Standardization (ISO) in 2023. Primary Test Methods
The standard identifies three main methods based on the expected permeability range of the ground: Constant Flow Rate Method: Used for higher permeabilities (
m/s). It involves maintaining a steady water flow and recording the head change over time.
Variable Head Method: Used for intermediate permeability ranges. This involves inducing an instantaneous head change (e.g., "slug test") and recording the decay of that head over time.
Rising/Falling Head Tests: Common field applications where water is either added to (falling) or removed from (rising) the borehole to measure the rate of level change. Equipment and Setup Requirements
To ensure accuracy, the standard specifies technical requirements for the following:
Borehole Preparation: Guidance on isolating test sections in both stable (rock) and non-stable (soil) ground, using perforated tubes, filter packs, or packers. Measurement Accuracy: Water Level: Accuracy must be within 0.01 meters.
Flow Rate: Devices must have an accuracy within 5% of their range.
Calibration: All equipment must be calibrated before use or at regular intervals during testing. Calculation and Reporting
Formulae: Permeability is calculated using factors like the radius and length of the test section, and the slope of the line from a graph of the natural log of the head versus time (
Documentation: A field report must be completed on-site, including an installation record (equipment type) and a log of measured values.
Informative Annexes: The standard includes examples of test reports and guidance on the interpretation of results. ISO 22282-2:2012 - Geotechnical investigation and testing
