Full title and description

ISO/TS 22475-2:2006 — Geotechnical investigation and testing — Sampling methods and groundwater measurements — Part 2: Qualification criteria for enterprises and personnel. This technical specification defines minimum qualification criteria (experience, knowledge, equipment and organisational aspects) for organisations and staff who carry out sampling and groundwater‑measurement services in accordance with ISO 22475‑1.

Abstract

ISO/TS 22475‑2:2006 specifies qualification criteria for enterprises and personnel performing sampling and groundwater measurements so that work executed under ISO 22475‑1 is carried out by appropriately experienced and equipped organisations and competent staff. The document provides criteria that can be used for first‑, second‑ or third‑party conformity assessment.

Scope

This Technical Specification sets out qualification criteria for organisations and personnel who perform sampling of soil, rock and groundwater and related groundwater measurements as described in ISO 22475‑1. It is intended to ensure that sampling and groundwater‑measurement tasks are carried out by competent teams using appropriate equipment and documented procedures; it also supports conformity assessment (first, second or third party).

Key topics and requirements

• Definition of minimum experience and training for personnel involved in sampling and groundwater measurement.
• Requirements for enterprise capability, equipment and quality assurance arrangements.
• Guidance on roles and responsibilities (e.g., qualified technicians/operators and responsible experts) and the relationship to ISO 22475‑1 technical principles.
• Provisions enabling first‑, second‑ or third‑party conformity assessment of sampling services.
• Cross‑references to related geotechnical and sampling standards (used to define competency areas and testing knowledge).

Typical use and users

Used by geotechnical contractors, site investigation teams, laboratories, employers specifying personnel qualifications in contracts, and conformity assessment bodies. Typical applications include defining competence requirements in tender documentation, internal QA/QC for borehole sampling and groundwater measurement projects, and as a reference when establishing certification or assessment schemes for field crews and technicians.

FAQ

Q: What is this standard?

A: ISO/TS 22475‑2:2006 is a technical specification that defines qualification criteria for enterprises and personnel who perform soil/rock sampling and groundwater measurements under the ISO 22475 series.

Q: What does it cover?

A: It covers minimum experience, training and organisational/equipment requirements so that sampling and groundwater‑measurement tasks are carried out competently and consistently; it also explains options for demonstrating conformity (first, second or third party).

Q: Who typically uses it?

A: Geotechnical contractors, drilling/sampling crews, laboratory managers, clients issuing tenders for site investigation, and certification or conformity assessment bodies.

Q: Is it current or superseded?

A: ISO/TS 22475‑2:2006 is recorded as withdrawn by ISO. Its subject matter has been revised and consolidated within more recent ISO/TS documents (notably the ISO/TS 24283 series published in 2022), so users should reference the 2022 series (and the current edition of ISO 22475‑1) for up‑to‑date qualification and assessment criteria.

Q: Is it part of a series?

A: Yes — it belongs to the ISO 22475 series (sampling and groundwater measurements). The series includes ISO 22475‑1 (technical principles) and related parts addressing conformity assessment and qualification criteria; more recent consolidation appears in ISO/TS 24283 (2022).

Q: What are the key keywords?

A: Geotechnical investigation, sampling, groundwater, personnel qualifications, conformity assessment, ISO 22475, field sampling, borehole sampling.
