Full title and description

Geotechnical investigation and testing — Geohydraulic testing — Part 1: General rules. This International Standard establishes the general rules, definitions and principles for in‑situ geohydraulic testing in soils and rock to determine permeability, transmissivity, storage coefficients and related hydrodynamic parameters as part of geotechnical investigation services.

Abstract

ISO 22282‑1:2012 defines concepts and specifies requirements for measuring permeability and related hydraulic properties in natural or treated soils and rock. It describes the purposes of geohydraulic testing (for example assessing grouting effectiveness, seepage/drainage, groundwater lowering, effects of cut‑offs and tunnels, and planning remedial measures) and sets out general principles for test execution, equipment and data reporting for tests involving groundwater.

Scope

ISO 22282‑1:2012 establishes the general rules and principles for geohydraulic testing to be used within geotechnical investigation programmes (referenced to EN 1997‑1 and EN 1997‑2). It covers terminology, objectives of testing, general requirements for test preparation and execution, conditions and limitations (focused on groundwater), and the reporting of results. The document does not provide detailed step‑by‑step procedures for every test type (these are covered in the specific parts of the ISO 22282 series).

Key topics and requirements

• Terminology and definitions for geohydraulic testing and hydraulic parameters (permeability coefficient, transmissivity, storage coefficient, intrinsic permeability).
• General principles for selecting and planning in‑situ hydraulic tests within a geotechnical investigation programme (objectives, hydrogeological setting, relation to EN 1997 requirements).
• Requirements for test equipment, instrumentation, and site preparation (borehole/well arrangement, sealing/packers where applicable).
• Guidance on test types, measurements to be taken, data quality, temperature/viscosity considerations and conversion between transmissivity/permeability metrics.
• Data analysis expectations and reporting — required test metadata, calculations, assumptions and presentation of hydraulic parameters for design and assessment purposes.
• Limitations: standard principally addresses tests with groundwater; other fluids or suspensions are not explicitly covered but may be considered via viscosity and permeability relations.

Typical use and users

Used by geotechnical and hydrogeological engineers, site investigation consultants, contractors conducting in‑situ permeability and pumping tests, researchers and regulatory bodies overseeing groundwater‑related construction and environmental works. Typical applications include assessing rock and soil permeability for tunnel and dam designs, evaluating grouting effectiveness, designing dewatering schemes, and characterising aquifer properties for engineering projects.

Related standards

ISO 22282 is a multipart series. Relevant related parts include: Part 2 — Water permeability tests in a borehole using open systems (ISO 22282‑2:2012). Part 3 — Water pressure tests in rock (ISO 22282‑3:2012). Part 4 — Pumping tests (drafts and DIS/FDIS development noted for Part 4). Part 5 — Infiltrometer tests (ISO 22282‑5:2012). Part 6 — Water permeability tests in a borehole using closed systems / packer tests (development history and DIS entries). The standard also sits alongside related geotechnical standards such as ISO 14688 (soil identification/classification) and ISO 22475 (sampling and groundwater measurements) referenced in geotechnical investigation practice.

FAQ

Q: What is this standard?

A: ISO 22282‑1:2012 is Part 1 of the ISO 22282 series that sets out general rules and principles for geohydraulic (in‑situ hydraulic) testing in soils and rock as part of geotechnical investigations.

Q: What does it cover?

A: It covers terminology, objectives, general requirements for preparing and conducting geohydraulic tests involving groundwater, expected data and reporting, and limitations (it does not replace the detailed procedures found in the specific parts of the series).

Q: Who typically uses it?

A: Geotechnical engineers, hydrogeologists, site investigation specialists, contractors performing borehole and pumping/infiltration tests, researchers and regulators involved in groundwater‑sensitive engineering works.

Q: Is it current or superseded?

A: The document was published in June 2012 (Edition 1) and, according to ISO, it was reviewed and confirmed in 2023. That confirmation indicates the 2012 edition remained current after ISO’s periodic review; users should check national/regional adoption or any later amendments before quoting for a specific project.

Q: Is it part of a series?

A: Yes — ISO 22282 is a multipart series. Part 1 provides general rules; related parts address specific test methods such as borehole open‑system permeability (Part 2), water pressure tests in rock (Part 3), pumping tests (Part 4), infiltrometer tests (Part 5) and closed‑system/packer tests (Part 6).

Q: What are the key keywords?

A: Permeability, transmissivity, storage coefficient, geohydraulic testing, borehole testing, pumping test, infiltrometer, packer tests, in‑situ testing, groundwater parameters.
