Water quality - Sampling - Part 15: Preservation and handling of samples of sludge, sediment and suspended matter (ISO/DIS 5667-15:2025)
ISO 5667-15:2009 provides guidance on procedures for the preservation, handling and storage of samples of sewage and waterworks sludge, suspended matter, saltwater sediments and freshwater sediments, until chemical, physical, radiochemical and/or biological examination can be undertaken in the laboratory.
The procedures in ISO 5667-15:2009 are only applicable to wet samples of sludge, sediment and suspended matter.

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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.
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).
This third edition cancels and replaces the second edition (ISO 5667-15:2009), which has been technically
revised.
The main changes are as follows:
— ‘suspended matter’ has been added to the title and ‘guidance’ has been deleted from the title;
— ISO/TS 5667-25 has been added as a reference;
— a flow diagram for preservation and storage of samples of sludge, sediment and suspended matter has
been added (in line with ISO 5667-3:2024);
— terms and definitions have been aligned with ISO 5667-3:2024;
— tables from clause 12 have been moved to Annex A;
— references in the previous Tables 1 to 3 have been added;
— the previous Table 3 has been split into Table A.3 ‘Hydrobiological analysis’ and Table A.4 ‘Microbiological
analysis’.
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

Introduction
[1]
This document is intended to be used in conjunction with ISO 5667-1, which deals with the design
of sampling programmes and sampling techniques.
Where possible, this document has been aligned with current standards. Where new research or validation
results have provided new insights, the latest knowledge has been used.
[6]
Guidance on validation protocols can be found in ISO/TS 5667-25 .
Tables A.1 to A.4 provide the validated preservation times or conditions as well as the descriptions of best
practice. Tables A.1 to A.4 also refer, for each parameter, to references available at the time of publication of
this document (i.e. ISO 5667-15:202x). This is however not an exhaustive list. Other preservation methods
may be used when they have been validated. However, it is strongly recommended that, where a method
validation is not available, the preservation times for the analyte listed in Tables A.1 to A.4 for ISO and CEN
test methods be followed. In case more than one storage time is provided in Tables A.1 to A.4, the order of
preferred use is:
— validated method;
— method provided by reference;
— best practice.
The preservation and storage conditions and maximum storage times per param
