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 3.
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.
International Standard 5165 was prepared by Technical Committee ISO/TC 28, Petroleum products and lubricants.
This third edition cancels and replaces the second edition (ISO 5165:1992), of which it constitutes a technical
revision.

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 establishes the rating of diesel fuel oil in terms of an arbitrary scale of cetane numbers
using a standard single cylinder, four-stroke cycle, variable compression ratio, indirect injected diesel engine. The
cetane number provides a measure of the ignition characteristics of diesel fuel oil in compression ignition engines. The
cetane number is determined at constant speed in a pre-combustion chamber-type compression ignition test engine.
However, the relationship of test engine performance to full scale, variable speed, variable load engines is not
completely understood.
This International Standard is applicable for the entire scale range from zero cetane number (CN) to 100 CN but typical
testing is in the range of 30 CN to 65 CN.
This test may be used for unconventional fuels such as synthetics, vegetable oils, etc. However, the relationship to the
performance of such materials in full scale engines is not completely understood.
Samples with fluid properties that interfere with the gravity flow of fuel to the fuel pump or delivery through the injector
nozzle are not suitable for rating by this method.
