Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
In other circumstances, particularly when there is an urgent market requirement for such documents, a
technical committee may decide to publish other types of normative document:
— an ISO Publicly Available Specification (ISO/PAS) represents an agreement between technical experts in
an ISO working group and is accepted for publication if it is approved by more than 50 % of the members
of the parent committee casting a vote;
— an ISO Technical Specification (ISO/TS) represents an agreement between the members of a technical
committee and is accepted for publication if it is approved by 2/3 of the members of the committee casting
a vote.
An ISO/PAS or ISO/TS is reviewed after three years in order to decide whether it will be confirmed for a
further three years, revised to become an International Standard, or withdrawn. If the ISO/PAS or ISO/TS is
confirmed, it is reviewed again after a further three years, at which time it must either be transformed into an
International Standard or be withdrawn.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO/TS 22475-3 was prepared by the European Committee for Standardization (CEN) Technical Committee
CEN/TC 341, Geotechnical investigation and testing, in collaboration with Technical Committee ISO/TC 182,
Geotechnics, Subcommittee SC 1, Geotechnical investigation and testing, in accordance with the Agreement
on technical cooperation between ISO and CEN (Vienna Agreement).
ISO 22475 consists of the following parts, under the general title Geotechnical investigation and testing —
Sampling methods and groundwater measurements:
⎯ Part 1: Technical principles for execution
⎯ Part 2: Qualification criteria for enterprises and personnel [Technical Specification]
⎯ Part 3: Conformity assessment of enterprises and personnel by third party [Technical Specification]

Introduction
ISO 22475-1 specifies the technical principles for the execution of sampling and groundwater measurements.
The quality of these services can be proven by:
a) a declaration of conformity by a contractor (first party control);
b) a declaration of conformity by a client (second party control);
c) a declaration of conformity by a conformity assessment body (third party control).
Every enterprise or individual may decide if and how they can prove the fulfilment of the technically related
criteria: by first-, second- or third-party control because no part of ISO 22475 requires such a declaration.
ISO/TS 22475-2 specifies the qualification criteria for enterprises and personnel that perform sampling and
groundwater measurements in accordance with ISO 22475-1.
The conformity assessment by third-party control may be made in accordance with the technical principles for
execution of sampling and groundwater measurements in accordance with ISO 22475-1 as indicated in
ISO/TS 22475-2 and the conformity assessment procedure given in this Technical Specification.

4.3.1.3 Arrangements shall be made in advance for the assessor and enterprise to meet at the enterprise
office and investigation site to demonstrate its skills, knowledge and safe working in accordance with the set
standards and procedures of the conformity assessment body.
4.3.2 Assessment procedure

these three years.
4.3.2.9 During these three years
