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 16703 was prepared by Technical Committee ISO/TC 190, Soil quality, Subcommittee SC 3, Chemical
methods and soil characteristics.

INTERNATIONAL STANDARD ISO 16703:2004(E)

Soil quality — Determination of content of hydrocarbon in the
range C to C by gas chromatography
10 40
1 Scope
This International Standard specifies a method for the quantitative determination of the mineral oil
(hydrocarbon) content in field-moist soil samples by gas chromatography.
The method is applicable to mineral oil contents (mass fraction) between 100 mg/kg and 10 000 mg/kg soil,
expressed as dry matter, and can be adapted to lower limits of detection.
This International Standard is applicable to the determination of all hydrocarbons with a boiling range of
175 °C to 525 °C, of n-alkanes from C H to C H , of isoalkanes, cycloalkanes, alkylbenzenes,
10 22 40 82
alkylnaphthalenes and polycyclic aromatic compounds, provided that they are not absorbed on the specified
column during the clean-up procedure.
This International Standard is not applicable to the quantitative determination of hydrocarbons < C
originating from gasolines.
On the basis of the peak pattern of the gas chromatogram obtained, and of the boiling points of the individual
n-alkanes listed in Annex B, the approximate boiling range of the mineral oil and some qualitative information
on the composition of the contamination can be obtained.
