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 on 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 the following

This document was prepared by Technical Committee ISO/TC 147, Water quality, Subcommittee SC 6,
Sampling (general methods).
This second edition cancels and replaces the first edition (ISO 5667-12:1995), which has been technically
revised.
A list of all parts in the ISO 5667 series can be found on the ISO website.
Introduction
This document should be read in conjunction with ISO 5667-1 and ISO 5667-15.
The general terminology used is in accordance with the various parts of ISO 6107, and more particularly,
with the terminology on sampling given in ISO 6107-2.

INTERNATIONAL STANDARD ISO 5667-12:2017(E)
Water quality — Sampling —
Part 12:
Guidance on sampling of bottom sediments from rivers,
lakes and estuarine areas
1 Scope
This document provides guidance on the sampling of unconsolidated sediments for the determination
of their geological, physical and chemical properties, as well as the determination of biological,
microbiological and chemical properties at the water and sediment interface. Guidance on achieving
sediment cores is given specifically for the measurement of rates of deposition and detailed strata
delineation. The main emphasis of this document is to provide methods that achieve sediment samples.
The environments considered are
— limnic (rivers, streams and lakes, natural and man-made), and
— estuarine, including harbours.
Industrial and sewage works for sludges, paleolimnological sampling and sampling of open ocean
sediments are specifically excluded from this document (and are addressed in ISO 5667-15), although
some techniques may apply to these situations. Sampling of suspended solids is outside the scope of
this document and reference can be made to ISO 5667-17 for such guidance.
2 Normative references

sampling techniques
