Water quality - Sampling - Part 1: Guidance on the design of sampling programmes and sampling techniques (ISO 5667-1:2023)
This document sets out the general principles for, and provides guidance on, the design of sampling programmes and sampling techniques for all aspects of sampling of water (including waste waters, sludges, effluents, suspended solids and sediments).
It does not include detailed instructions for specific sampling situations, which are covered in the various other parts of ISO 5667 and in ISO 19458.

Qualité de l'eau - Échantillonnage - Partie 1: Recommandations relatives à la conception des programmes et des techniques d’échantillonnage (ISO 5667-1:2023)
Le présent document énonce les principes généraux et fournit des recommandations relatives à la conception des programmes et des techniques d'échantillonnage, en tenant compte de tous les aspects relatifs à l'échantillonnage des eaux (y compris des eaux résiduaires, des boues, des effluents, des matières en suspension et des sédiments).
Il n'inclut pas de consignes détaillées pour les cas d'échantillonnages spécifiques, qui sont couvertes par les différentes autres parties de l'ISO 5667 et dans l'ISO 19458.
Kakovost vode - Vzorčenje - 1. del: Navodilo za načrtovanje programov in tehnik vzorčenja (ISO 5667-1:2023)
Ta dokument določa splošna načela ter zagotavlja smernice za načrtovanje programov vzorčenja in tehnik vzorčenja za vse vidike vzorčenja vode (vključno z odpadnimi vodami, blatom, izlivi, neraztopljenimi trdnimi snovmi in usedlinami).
Ne zajema podrobnih navodil za specifične okoliščine vzorčenja, ki so obravnavane v različnih drugih delih standardov ISO 5667 in ISO 19458.

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.

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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see
www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 147, Water quality, Subcommittee SC 6,
Sampling (general methods), in collaboration with the European Committee for Standardization (CEN)
Technical Committee CEN/TC 230, Water analysis, in accordance with the Agreement on technical
cooperation between ISO and CEN (Vienna Agreement).
This fourth edition cancels and replaces the third edition (ISO 5667-1:2020), of which it constitutes a
minor revision. The changes compared to the previous edition are as follows:
— corrections have been made to 10.3 and associated cross references to Annex A;
— subclauses have been included in Clause 7 referring to the most recent additions to the ISO 5667
series.
A list of all parts in the ISO 5667 series can be found on the ISO website.
Any feedback or questions on this document should be directed to the user’s national standards body. A

FINAL DRAFT INTERNATIONAL STANDARD ISO/FDIS 5667-1:2022(E)
Water quality — Sampling —
Part 1:
Guidance on the design of sampling programmes and
sampling techniques
1 Scope
This document sets out the general principles for, and provides guidance on, the design of sampling
programmes and sampling techniques for all aspects of sampling of water (including waste waters,
sludges, effluents, suspended solids and sediments).
This document does not include detailed instructions for specific sampling situations, which are
covered in various other parts of ISO 5667 and in ISO 19458.
