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).

This document was prepared by Technical Committee ISO/TC 147, Water quality, Subcommittee SC 6,

Sampling management.

This third edition cancels and replaces the second edition (ISO 5667-1:2006), which has been technically

revised. The main changes compared to the previous edition are as follows:
— incorporation of updated references;
— addition of a section on variation from normal sampling conditions;
— expansion of Clause 7 on sampling from specific types of water;
— introduction of a clause on passive sampling;
— incorporation of sample container provisions in Clause 12;
— expansion of Clause 15 to address data management;

— addition of annexes on field documentation, emerging sampling techniques, preparation of sampling

equipment.

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.

4 General safety precautions

Attention is drawn to the requirements of national and/or regional health and safety regulations.

The following are general examples of safety considerations.
4.1 Safety of Personnel

The enormously wide range of conditions encountered in sampling water bodies and bottom sediments

can subject sampling personnel to a variety of safety and health risks. Precautions should be taken

to avoid inhalation of toxic gases and ingestion of toxic materials through the nose, mouth and skin.

Personnel responsible for the design of sampling programmes and for carrying out sampling operations

should ensure that sampling personnel are informed of the necessary precautions to be taken in

sampling operations.

Weather conditions should be taken into account in order to ensure the safety of personnel and

equipment and it is essential that life jackets and lifelines should be worn when sampling large masses

of water. Before sampling from ice-covered waters, the location and extent of weak ice should be

carefully checked. If self-contained underwater breathing apparatus or other diving equipment is used,

it should always be checked and maintained in accordance with relevant ISO or national standards to

ensure reliability.

SIST EN ISO 5667-1:2022
ISO 5667-1:2020(E)

Boats or platforms used for sampling purposes should be capable of being maintained in a stable

condition. In all waters, precautions should be taken in relation to commercial ships and fishing

vessels; for example, the correct signal flags should be flown to indicate the nature of the work being

undertaken.

Sampling from unsafe sites, such as unstable river banks, should be avoided wherever possible. If this

is not possible, the operation should be conducted by a team using appropriate precautions rather than

by a single operator. Wherever possible, sampling from bridges should be used as a substitute for bank

sampling unless bank conditions are the specific subject of the sampling study.

Safe access to sampling sites in all weather is essential for frequent routine sampling. Where relevant,

precautions should be taken where additional natural hazards are present, such as fauna or flora, that

can endanger the health or safety of personnel.

Hazardous materials (e.g. bottles containing concentrated acids) should be properly labelled.

If instruments or other items of equipment are to be installed on a river bank for sampling

purposes, locations that are susceptible to flooding or vandalism should be avoided or appropriate

precautions taken.

Many other situations arise during the sampling of water when special precautions should be taken

to avoid accidents. For example, some industrial effluents can be corrosive or can contain toxic or

flammable materials. The potential dangers associated with contact with sewage should also not be

overlooked; these can be gaseous, microbiological, radiological, virological or zoological, such as from

amoebae or helminthes.

Gas protection equipment, breathing apparatus, resuscitation apparatus and other safety equipment

should be available when sampling personnel need to enter sampling locations containing hazardous

atmospheres. In addition, the concentration of oxygen and of any likely toxic or
...

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

DRAFT INTERNATIONAL STANDARD ISO/DIS 5667-1:2019(E)
Water quality — Sampling —
Part 1:
Guidance on the design of sampling programmes and
sampling techniques
1 Scope

This part of ISO 5667 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.
2 Normative references
There are no normative references.
3 Terms and definitions

ISO and IEC maintain terminological databases for use in standardization at the following addresses:

4 General safety precautions

The enormously wide range of conditions encountered in sampling water bodies and bottom sediments

can subject sampling personnel to a variety of safety and health risks. Precautions should be taken

to avoid inhalation of toxic gases and ingestion of toxic materials through the nose, mouth and skin.

Personnel responsible for the design of sampling programmes and for carrying out sampling operations

should ensure that sampling personnel are informed of the necessary precautions to be taken in

sampling operations.

Attention is drawn to the requirements of national and/or regional health and safety regulations.

Weather conditions should be taken into account in order to ensure the safety of personnel and

equipment and it is essential that life jackets and lifelines should be worn when sampling large masses

of water. Before sampling from ice-covered waters, the location and extent of weak ice should be

carefully checked. If self-contained underwater breathing apparatus or other diving equipment is used,

it should always be checked and maintained in accordance with relevant ISO or national standards to

ensure reliability.

Boats or platforms used for sampling purposes should be capable of being maintained in a stable

condition. In all waters, precautions should be taken in relation to commercial ships and fishing

vessels; for example, the correct signal flags should be flown to indicate the nature of the work being

undertaken.

Sampling from unsafe sites, such as unstable river banks, should be avoided wherever possible. If this

is not possible, the operation should be conducted by a team using appropriate precautions rather than

by a single operator. Wherever possible, sampling from bridges should be used as a substitute for bank

sampling unless bank conditions are the specific subject of the sampling study.

Safe access to sampling sites in all weather is essential for frequent routine sampling. Where relevant,

precautions should be taken where additional natural hazards are present, such as fauna or flora, that

can endanger the health or safety of personnel.

Hazardous materials (e.g. bottles containing concentrated acids) should be properly labelled.

If instruments or other items of equipment are to be installed on a river bank for sampling

purposes, locations that are susceptible to flooding or vandalism should be avoided or appropriate

precautions taken.

Many other situations arise during the sampling of water when special precautions should be taken

to avoid accidents. For example, some industrial effluents can be corrosive or can contain toxic or

flammable materials. The potential dangers associated with contact with sewage should also not be

overlooked; these can be gaseous, microbiological, virological or zoological, such as from amoebae or

helminthes.

Gas protection equipment, breathing apparatus, resuscitation apparatus and other safety equipment

should be available when sampling personnel need to enter sampling locations containing hazardous

atmospheres. In addition, the concentration of oxygen and of any likely toxic or asphyxiating vapour or

gas likely to be present should be measured before personnel enter enclosed spaces.

In the sampling of steam and hot discharges, special care is necessary, and recognized sampling

techniques designed to remove hazards should be applied.

The handling of radioactive samples requires special care, and the special techniques required should

be strictly applied.

The use of electrically operated sampling equipment in or near water can present special electrocution

hazards. Work procedures, site design and equipment maintenance should be planned so as to minimize

these hazards.
