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.
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.
International Standard ISO 5667-13 was prepared by Technical Committee ISO/TC 147,
, Subcommittee SC 6,
Water quality Sampling (general method).
International Standard ISO 5667 consists of the following parts, under the general title
Water quality — Sampling
— Part 1: Guidance on the design of sampling programmes
— Part 2: Guidance on sampling techniques
— Part 3: Guidance on the preservation and handling of samples

Introduction
This part of ISO 5667 should be read in conjunction with ISO 5667-1,
ISO 5567-2 and ISO 5667-3. The general terminology used is in accordance
with the various parts of ISO 6107.
Sampling and the determination of the physical and chemical properties of
sludges and related solids are normally carried out for a specific purpose. The
sampling methods given are suitable for general use but do not exclude
modification in the light of any special factor known to the analyst receiving the
samples or any operational reason dictating the need for sampling.
The importance of using a valid sampling technique cannot be overemphasized
if the subsequent analysis is to be worthwhile. It is important that the personnel
taking and analysing the sample be fully aware of its nature and the purpose for
which the analysis is required before embarking on any work programme. Full
cooperation with the laboratory that will be analysing the samples ensures that
the most effective application of the sampling occasion can be made. For
example, the use of method-specific sample preservation techniques will assist
in the accurate determination of results.

Water quality — Sampling —
Part 13:
Guidance on sampling of sludges from sewage and
water treatment works
1 Scope
This part of ISO 5667 gives guidance on the sampling of sludges from wastewater
treatment works, water treatment works and industrial processes. It is applicable to all
types of sludge arising from these works and also to sludges of similar characteristics,
for example septic tank sludges. Guidance is also given on the design of sampling
programmes and techniques for the collection of samples.
This part of ISO 5667 is applicable to sampling motivated by different objectives, some
of which are to:
— provide data for the operation of activated sludge plants;
— provide data for the operation of sludge treatment facilities;
— determine the concentration of pollutants in wastewater sludges for disposal to
landfill;
— test whether prescribed substance limits are contravened when sludge is used in
agriculture;
— provide information on process control in potable and wastewater treatment,
including:
a) addition or withdrawal of solids;
b) addition or withdrawal of liquid;
— provide information for legally enforceable aspects of the disposal of sewage and
waterworks’ sludges;
— facilitate special investigations into the performance of new equipment and
processes;
— optimize costs; for example for the transport of sludges for treatment and/or
disposal.
NOTE When designing a sludge sampling programme, it is essential that the objectives of the study be
kept in mind, so that the information gained corresponds to that required. In addition, the data should not
be distorted by the use of inappropriate techniques, such as inadequate storage temperatures or the
sampling of unrepresentative parts of a treatment plant.

3 Definitions
For the purposes of this part of ISO 5667, the following definitions apply:
3.1 grab sample
discrete sample taken randomly (with regard to time and/or location) from a body of
sludge
[Based on ISO 6107-2]
3.2 composite sample
two or more samples or subsamples, mixed together in appropriate known proportions
(either discretely or continuously), from which the average value of a desired
characteristic may be obtained
NOTE The proportions are usually based on time or flow measurements.

3.3 flow-related sampling
samples taken at varying time intervals governed by material flow
NOTE This usually applies to liquid sludges; further guidance can be drawn from ISO 5667-10.
3.4 proportional sampling
technique for obtaining a sample from flowing sludge in which the frequency of
collection (in the case of discrete sampling), or the sample flowrate (in the case of
continuous sampling), is directly proportional to the flow rate of the sampled sludge
4 Sampling equipment
4.1 Materials
The sampling of sludge from fixed points can require the installation of permanent
equipment, even if this is only an additional pipe and valve to the processing plant. It is
important to verify that any such equipment is regularly cleaned and that it is free from
corrosion. In addition, it will be necessary to assess the potential for interference on
any test results that the equipment may have. For example, the use of aluminium
extension pipes to a sampling valve would be inappropriate if the samples were being
taken for the analysis of an aluminium flocculation assister. In general, the laboratory
performing the sludge examination should be consulted before installation of any fixed
point equipment or at the implementation of a new sampling scheme.
Tools should be chosen to avoid contamination by substances of interest. They should
be kept clean and corrosion free. Plastics utensils and polytetrafluoroethylene pallet
knives may be used if they prove to be robust and the absence of any contaminating
influence can be demonstrated. High alloy steels should be avoided if trace metals are
to be determined. The use of stainless steel tools is routinely adopted but the
possibility of contamination needs to be recognized and tested for if analyses for
elements such as chromium are to be performed on the sludge sample. Old, rusty
tools or those with chipped or flaking surface coatings and painted surfaces should not
be used, as they may contribute to random contamination of samples.
Polyethylene, polypropylene, polycarbonate and glass containers are satisfactory from
the point of view of chemical stability when sludge sampling (see also 6.1). However,
caution should be exercised since containers can become pressurized due to gas
production in wastewater sludges and explosive situations may occur. Guidance on
overcoming this problem is given in clause 7.
Glass containers should be used when organic constituents, such as pesticides, are to
be determined whereas polyethylene containers are preferable for sampling
parameters of general interest such as pH and dry matter. Polyethylene containers
may not be suitable for collecting samples to be subjected to some trace metal
analysis (for example mercury); these containers should only be used if preliminary
tests indicate acceptable levels of interference.

ISO 5667-13:1997(E) ISO
The introduction of aged material from the dead space in sample lines can also
contribute to contamination of samples due to corrosion, see 5.3.3, and can prove to
be a serious potential source of error if not eliminated.
Refer to standard analytical procedures for detailed guidance on the type of sample
container to be used. For guidance on the cleaning of sample containers, see
ISO 5667-3.
4.2 Equipment
In general, sludge sampling equipment is usually most practical if it is as simple in
design and construction as possible. The characteristics of a sludge can vary
according to type and solids content, and therefore the manner of handling in a
sampling device is dependent upon the physical properties; no general
recommendations can therefore be given but some specific examples of equipment for
liquid sludges under particular circumstances are given in annexes A and B.
5 Sampling procedure
5.1 Sampling regime
The most appropriate way of sampling in any situation will depend on several factors:
a) access to the sampling point by personnel;
b) the practicality of installing and maintaining automatic equipment if appropriate;
c) the practicalities of interrupting safely a stream of moving liquid sludge or cake
when manually sampling; and
d) the nat
