Full title and description

Geotechnical investigation and testing — Sampling methods and groundwater measurements — Part 3: Conformity assessment of enterprises and personnel by third party. This technical specification defines how third-party conformity assessment (certification/assessment) applies to enterprises and personnel who perform specified sampling and groundwater measurement tasks in accordance with the related ISO 22475 series.

Abstract

ISO/TS 22475-3:2007 is applicable to the conformity assessment of enterprises and personnel performing specified parts of sampling and groundwater measurements according to ISO 22475-1 and complying with the technical qualification criteria given in ISO/TS 22475-2; assessment is intended to be carried out by an independent third party.

Scope

The technical specification covers requirements and procedures for third‑party conformity assessment of enterprises and personnel who carry out specified soil, rock and groundwater sampling and groundwater measurements according to ISO 22475-1, and who are expected to meet the qualification criteria described in ISO/TS 22475-2. It is focused on assessment and certification practices (competence, documentation, audit), not on laboratory test methods or sampling techniques themselves.

Key topics and requirements

• Scope and purpose of third‑party conformity assessment for sampling and groundwater measurement activities.
• Requirements for assessing enterprise competence (management, procedures, traceability, records).
• Requirements for assessing personnel competence and qualifications in accordance with ISO/TS 22475-2 (responsible experts and operational staff).
• Auditing and certification principles applicable to geotechnical fieldwork and groundwater measurement activities (third‑party control).
• Relationship to the ISO 22475 series (distinguishes assessment/certification from the sampling and measurement methods in Part 1).

Typical use and users

Used by accreditation and certification bodies, conformity assessment/registration bodies, geotechnical consulting firms, field sampling contractors, environmental and groundwater survey organisations, regulatory authorities that wish to check or require certified competence for sampling/groundwater measurement activities, and by clients procuring geotechnical sampling services who need to set or verify competence criteria. National standards bodies and organisations adopting the text for national application also used or referenced this specification.

Related standards

Main related documents are ISO 22475-1 (sampling methods and groundwater measurements — guidance on sampling), ISO/TS 22475-2 (technical qualification criteria for personnel), and the later ISO/TS 24283 series (Qualification criteria and assessment — Parts 2 and 3) which have been published in 2022 and have superseded/revised aspects of the earlier TS 22475 series. European and national adoptions (CEN/CEN ISO, DIN, BSI) also exist for the Part 3 text.

FAQ

Q: What is this standard?

A: ISO/TS 22475-3:2007 is a technical specification that addressed third‑party conformity assessment of enterprises and personnel performing specified geotechnical sampling and groundwater measurement tasks in accordance with the ISO 22475 series. It defined how certification/assessment could be applied to demonstrate competence.

Q: What does it cover?

A: It covers the scope and requirements for conducting third‑party assessments and certification of organisations and staff involved in sampling soils, rocks and groundwater and performing groundwater measurements — including competence criteria, auditing principles and documentation needed for conformity assessment (not the sampling/test methods themselves).

Q: Who typically uses it?

A: Certification and accreditation bodies, geotechnical consultancies, field sampling contractors, environmental/groundwater survey organisations, regulators and procurement clients who require or verify certified competence for sampling and groundwater measurements.

Q: Is it current or superseded?

A: ISO/TS 22475-3:2007 is listed as withdrawn by ISO. The subject of qualification criteria and conformity assessment in this area has been revised and published in the ISO/TS 24283 series (including ISO/TS 24283-2:2022 and ISO/TS 24283-3:2022), which now provide updated qualification criteria and assessment guidance. Some national/adopted versions were withdrawn or updated when the replacement TS documents were published.

Q: Is it part of a series?

A: Yes — it was Part 3 of the ISO 22475 family (which includes Part 1: sampling methods and groundwater measurements, and Part 2: personnel qualification criteria). The subject has since been reorganised into the ISO/TS 24283 series (Parts addressing responsible experts and qualified enterprises).

Q: What are the key keywords?

A: Geotechnical investigation; sampling; groundwater measurement; conformity assessment; third‑party certification; qualification; personnel competence; ISO 22475; ISO/TS 24283.
