ISO 3924:2010(E)
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 3924 was prepared by the European Committee for Standardization (CEN) Technical Committee
CEN/TC 19, Gaseous and liquid fuels, lubricants and related products of petroleum, synthetic and biological
origin, in collaboration with Technical Committee ISO/TC 28, Petroleum products and lubricants, in
accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).

This method is harmonized with the analogous IP 406 and ASTM D2887 methods.
This third edition cancels and replaces the second edition (ISO 3924:1999), to which two additional
informative annexes, Annexes A and B, have been added and some updating on definitions has been
incorporated. (The Annex A in ISO 3924:1999 has become Annex C in this revised edition.) Annex A basically
contains a table for a correlation of certain data with those obtained using the ISO 3405 method and some
extra wording to the basic procedure, without changing the scope. With this information, the revised ISO 3924
becomes an updated document, describing the method actually in practice without changing the basic
procedure. The data presented in Annex A allow a reference in modern, global specifications, such as for
aviation fuels. This underlines the fact that availability of these chemical data in an ISO method supports their
use in these specific fields.
Also, because ISO 3924 is extensively used and referenced in many fuel specifications and there is a
requirement for a faster method, Annex B describes a method that, without any instrumental adaptation,
reduces the analysis time by a factor 5.

INTERNATIONAL STANDARD ISO 3924:2010(E)

Petroleum products — Determination of boiling range
distribution — Gas chromatography method
WARNING — The use of this International Standard may involve hazardous materials, operations and
equipment. This International Standard does not purport to address all of the safety problems
associated with its use. It is the responsibility of the user of this International Standard to establish
appropriate safety and health practices and determine the applicability of regulatory limitations prior
to use.
1 Scope
This International Standard specifies a method for the determination of the boiling-range distribution of
petroleum products. The method is applicable to petroleum products and fractions with a final boiling point of
538 °C or lower at atmospheric pressure as determined by this International Standard. This International
Standard is not applicable to gasoline samples or gasoline components. The method is limited to products
having a boiling range greater than 55 °C and having a vapour pressure sufficiently low to permit sampling at
ambient temperature.
The method has successfully been applied to samples containing biodiesel up to 10 %.
NOTE For the purposes of this International Standard, the term “% (m/m)” is used to represent the mass fraction of a
material.
