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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO [had/had not] received notice of
(a) patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.
Any trade name used in this document is information given for the convenience of users and does not

related to conformity assessment, as well as information about ISO's adherence to the World Trade
Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www.iso.org/iso/foreword.html.

Environmental Solid Matrices — Determination of
hydrocarbon content in the range of C to C by gas

chromatography
1 Scope
This International Standard specifies a method for the quantitative determination of the mineral oil
(hydrocarbon) (C to C ) content in soil and waste samples by gas chromatography.
10 40
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.
Using this standard all hydrocarbons with a boiling range of approximately 175 °C to 525 °C, e.g. n-alkanes
from C H to C H , isoalkanes, cycloalkanes, alkyl benzenes, alkyl naphthalenes and polycyclic aromatic
10 22 40 82
compounds are determined as hydrocarbons, provided they do not adsorb on the Florisil column during
clean-up.
The standard can also be applied to determine any fraction in-between the range n-C to n-C .
10 40
Volatile hydrocarbons cannot be quantitatively determined using this standard. This will affect the
determination of some common hydrocarbon fue
