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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. 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.
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.
ISO 12404 was prepared by Technical Committee ISO/TC 190, Soil quality, Subcommittee SC 3, Chemical
methods and soil characteristics.

Introduction
Screening methods, which can be chemical, physical or biochemical in nature, can often be applied in a quick
and simple manner. Performance of quick and simple tests can be used in the field (i.e. on-site) and, in some
cases, are also applicable for laboratory use. They can indicate the presence or absence of an analyte, or
provide a qualitative estimate of a concentration or value, or generate a quantitative result. They can also be
used to produce a spatial distribution of concentrations or values within a site, which can be supported by
subsequent reference (laboratory-base) analysis. When used in this way, the purpose is generally to obtain
information on target parameters or groups of parameters and the location of unusual concentrations, possibly
prior to undertaking a more detailed study or investigation. For these purposes, the bias and precision of
these methods need not be to the same level as conventional laboratory reference methods, for example as
demonstrated by International Standards, as the initial objective of their use is to obtain as much information as
possible in a relatively short period of time on the presence or absence, or range of concentrations likely to be
determined for a particular site. It may be more important to obtain a result quickly or with an improved spatial
resolution as an indication of the magnitude and likely concentration, rather than precise and unbiased values.
Typically, for measurement techniques, a result may be obtained in one of three ways. Firstly, as a qualitative
presence or absence result. Secondly, as a semi-quantitative result expressed within a relatively wide range of
values, and thirdly, as a result with an accompanying uncertainty of measurement with a significantly smaller
range of values that might be expected. (The third option is usually a result generated using a laboratory
reference method, with the uncertainty of measurement of laboratory reference methods generally being
smaller than that of screening methods.) Whichever result is generated depends on the nature and type of the
screening method used, as well as the technology on which the screening method is based.
The use of screening methods usually increases the efficiency of a site investigation, while providing as much
information as that obtained in situations where only laboratory reference methods are used. Whilst the use
of these rapid measurement techniques at a particular site should not replace conventional analysis, th
