Petroleum products - Determination of knock characteristics of motor fuels - Research method (ISO 5164:2005)
ISO 5164:2005 establishes the rating of liquid spark-ignition engine fuel in terms of an arbitrary scale of octane numbers using a standard single cylinder, four-stroke cycle, variable compression ratio, carburetted, CFR engine operated at constant speed. Research octane number (RON) provides a measure of the knock characteristics of motor fuels in automotive engines under mild conditions of operation.
T ISO 5164:2005 is applicable for the entire scale range from 0 RON to 120 RON, but the working range is 40 RON to 120 RON. Typical motor fuel testing is in the range of 88 RON to 101 RON.
ISO 5164:2005 can be used for oxygenate-containing fuels containing up to 4,0 % (m/m) oxygen.
Mineralölerzeugnisse - Bestimmung der Klopffestigkeit von Ottokraftstoffen - Research-Verfahren (ISO 5164:2005)
Diese Internationale Norm legt die Bestimmung der Klopffestigkeit von Kraftstoffen für Ottomotoren fest,
angegeben nach einer vereinbarten Skala von Octanzahlen, und zwar unter Verwendung eines genormten
CFR-Motors (Viertakt, Einzylinder, Vergaser, variables Verdichtungsverhältnis), der bei konstanter
Geschwindigkeit betrieben wird. Die Research-Octanzahl (ROZ) ist ein Maß für die Klopffestigkeit von
Kraftstoffen für Ottomotoren unter leichten Betriebsbedingungen.
Diese Internationale Norm ist anwendbar auf den gesamten Bereich von 0 ROZ bis 120 ROZ, der
Arbeitsbereich ist jedoch 40 ROZ bis 120 ROZ. Der typische Bereich zur Bewertung von Otto-Kraftstoffen ist
88 ROZ bis 101 ROZ.
Diese Internationale Norm kann für Kraftstoffe mit sauerstoffhaltigen Komponenten bis zu einem Gehalt an
Sauerstoff von 4,0 % (m/m) angewandt werden.
Bestimmte Gase und Dämpfe, wie halogenierte Kühlmittel aus Klimaanlagen, die in der Umgebung des CFR-Motors
anwesend sein können, können einen messbaren Effekt auf die ROZ-Bestimmung haben. Elektrische
Spannungs- oder Frequenzstörungen können die ROZ-Bestimmungen auch beeinflussen.
ANMERKUNG 1 Diese Internationale Norm legt Betriebsbedingungen in SI-Einheiten fest, die Maße des Prüfmotors sind
jedoch Inch-Pound-Einheiten, da dies die Fertigungsmaße sind, und deshalb enthalten einige Verweise in dieser
Internationalen Norm diese Einheiten in Klammern.
ANMERKUNG 2 Für den Zweck dieser Internationalen Norm dürfen die Symbole % (V/V) bzw. % (m/m) verwendet
werden, um Volumenanteile in % bzw. Massenanteile in % auszudrücken.
Produits pétroliers - Détermination des caractéristiques antidétonantes des carburants pour moteurs automobile - Méthode recherche (ISO 5164:2005)
L'ISO 5164:2005 spécifie une méthode de cotation des carburants liquides pour moteurs à allumage commandé, exprimée sur une échelle arbitraire d'indice d'octane, en utilisant un moteur monocylindre à quatre temps, à taux de compression variable, à carburateur, le moteur CFR fonctionnant à vitesse constante. L'indice d'octane recherche (RON) constitue une mesure des caractéristiques antidétonantes des carburants dans les moteurs pour automobiles dans des conditions de fonctionnement peu sévères.
L'ISO 5164:2005 s'applique dans une gamme d'indices d'octane allant de 0 RON à 120 RON, mais les essais courants se font entre 40 RON et 120 RON. La gamme de mesure classique pour les carburants moteurs va de 88 RON à 101 RON.
L'ISO 5164:2005 est applicable aux carburants qui comportent des oxygénés et contiennent au maximum 4,0 % (m/m) d'oxygène.

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 5164 was prepared by Technical Committee ISO/TC 28, Petroleum products and lubricants.
This third edition cancels and replaces the second edition (ISO 5164:1990), which has been technically
revised.

Introduction
The purpose of this International Standard is to accord ISO status to a test procedure that is already used in a
standardized form all over the world. The procedure in question is published by ASTM International as
Standard Test Method D 2699-01a.
By publishing this International Standard, ISO recognizes that this method is used in its original text in many
member countries and that the standard equipment and many of the accessories and materials required for
the method are obtainable only from specific manufacturers or suppliers. To carry out the procedure requires
reference to six annexes and three appendices of ASTM D 2699-01a, contained in the Annual Book of ASTM
1)
Standards, Section 5 . The annexes detail the specific equipment and instrumentation required, the critical
component settings and adjustments, and include the working tables of referenced settings. The appendices
provide background and additional insight about auxiliary equipment, operational techniques and the concepts
relative to proper maintenance of the engine and instrumentation items.
The accumulated motor fuel data relating to knock characteristics determined in many countries has, for many
2)
years, been based on the use of the CFR engine and the ASTM octane test methods. Accepted worldwide,
petroleum industry octane number requirements for motor fuels are defined by the research method and
associated CFR F-1 Octane Rating Unit, which emphasizes the need for this method and test equipment to be
standardized. The initiation of studies to use a different engine for ISO purposes has therefore been
considered an unnecessary duplication of effort.
It is further recognized that this method for rating motor fuels, which does include metric operating conditions,
is nevertheless an exceptional case in that the CFR engine is manufactured to inch dimensions and requires
numerous settings and adjustments to inch dimensions. Application of metrication to these dimensions and
tolerances can only be accomplished by strict numerical conversion which would not reflect proper metric
engineering practice. Attempts to utilize metric measurement instruments for checking component dimensions
to the numerically converted metric values would only introduce an additional source of test variability.
For these reasons, it has been considered desirable by ISO Technical Committee 28, Petroleum products and
lubricants, to adopt the ASTM D 2699 standard rewritten to comply with the ISO Directives, Part 2, Rules for
the structure and drafting of International Standards. However, this International Standard refers to annexes
and appendices of ASTM D 2699 without change because of their extensive detail. These annexes and
appendices are not included in this International Standard because they are published in the Annual Book of
ASTM Standards, Section 5.
