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 12010 was prepared by Technical Committee ISO/TC 147, Water quality, Subcommittee SC 2, Physical,
chemical and biochemical methods.

Introduction
The user should be aware that particular problems might require the specifications of additional marginal conditions.
INTERNATIONAL STANDARD ISO 12010:2012(E)
Water quality — Determination of short-chain polychlorinated
alkanes (SCCPs) in water — Method using gas
chromatography-mass spectrometry (GC-MS) and negative-ion
chemical ionization (NCI)
WARNING — Persons using this International Standard should be familiar with normal laboratory
practice. This International Standard does not purport to address all of the safety problems, if any,
associated with its use. It is the responsibility of the user to establish appropriate safety and health
practices and to ensure compliance with any national regulatory conditions.
IMPORTANT — It is absolutely essential that tests conducted in accordance to this International
Standard be carried out by suitably qualified staff.
1 Scope
This International Standard specifies a method for the quantitative determination of the sum of short-chain
polychlorinated n-alkanes, also known as short-chain polychlorinated paraffins (SCCPs), in the carbon bond
range n-C to n-C inclusive, in mixtures with chlorine mass fractions (“contents”) between 49 % and 67 %,
10 13
including approximately 6 300 of approximately 8 000 congeners.
This method is applicable to the determination of the sum of SCCPs in unfiltered surface water, ground water,
drinking water and waste water using gas chromatography-mass spectrometry with electron capture negative
ionization (GC-ECNI-MS).
The method can be applied to samples containing 0,1 µg/l to 10 µg/l. Depending on the waste water matrix, the
lowest detectable concentration is estimated to be >0,1 µg/l.
