Full title and description

ISO/TS 22476-10:2005 — Geotechnical investigation and testing — Field testing — Part 10: Weight sounding test. This technical specification defines the equipment, execution and reporting principles for the weight sounding test (WST) used in ground investigations to obtain a continuous indication of soil resistance and layer sequence.

Abstract

ISO/TS 22476-10:2005 provides requirements for carrying out weight sounding tests as part of geotechnical site investigations (in accordance with EN 1997‑1 and EN 1997‑2). The document covers test intent, basic apparatus and the procedures to obtain a continuous soil resistance profile useful for assessing relative density of cohesionless soils and depths to very dense or stiff layers. The Technical Specification was later withdrawn and replaced by a full International Standard (ISO 22476-10:2017).

Scope

Specifies requirements for the weight sounding test (WST) as an indirect field method within geotechnical site investigations. The TS addresses equipment description, test execution and basic reporting requirements for using the weight sounding device on natural soils, made ground and fills (including tests performed over water). The intended uses include producing a continuous soil-resistance profile, indicating layer sequence, estimating relative density of cohesionless soils and identifying depths to very dense or stiff layers relevant for end-bearing pile design.

Key topics and requirements

• Definition and purpose of the weight sounding test (WST) as a continuous field sounding method.
• Minimum equipment and instrument descriptions for the WST apparatus.
• Procedures for test execution, including emplacement, loading and specified observations/measurements.
• Guidance on interpretation: correlation of sounding resistance to soil density and layer boundaries; limitations and expected accuracy.
• Reporting requirements: test location, equipment, procedure details, raw and processed sounding resistance profile and interpretative notes.

Typical use and users

Used by geotechnical engineers, site investigation contractors, engineering consultancies and researchers for preliminary and detailed ground investigations. Typical applications include rapid profiling of cohesionless deposits, locating dense layers for pile design, quality control of made ground and site reconnaissance where continuous resistance information is required.

Related standards

Closely related to other parts of the ISO 22476 series covering field testing (e.g., dynamic probing, cone penetration and other sounding methods) and to EN 1997 series (Eurocode 7) for geotechnical design and investigation procedures. The 2005 Technical Specification was withdrawn and superseded by ISO 22476‑10:2017 (International Standard) which consolidates and expands the WST requirements.

FAQ

Q: What is this standard?

A: ISO/TS 22476-10:2005 is a Technical Specification that defined requirements for the weight sounding test (WST) used in geotechnical site investigations. It has been withdrawn and replaced by a later International Standard.

Q: What does it cover?

A: It covers the purpose, basic apparatus, execution procedures and reporting for the weight sounding test to produce a continuous profile of soil resistance and aid interpretation of layer sequence and relative density.

Q: Who typically uses it?

A: Geotechnical engineers, site investigation contractors and consultants performing field sounding and preliminary or detailed ground investigations.

Q: Is it current or superseded?

A: ISO/TS 22476-10:2005 was withdrawn. The current, published replacement is ISO 22476-10:2017 (International Standard), which should be used for up-to-date requirements.

Q: Is it part of a series?

A: Yes — it is Part 10 of the ISO 22476 series (Geotechnical investigation and testing — Field testing). The series includes other parts covering dynamic probing, cone penetration and additional field tests used in geotechnical investigations.

Q: What are the key keywords?

A: Weight sounding test, WST, field testing, soil sounding, site investigation, relative density, layer sequence, ISO 22476.
