Petroleum products - Determination of knock characteristics of motor and aviation fuels - Motor method (ISO 5163:2014)
EN ISO 5163 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, variablecompression ratio, carburetted, CFR engine operated at constant speed. Motor octane number (MON) provides a measure of the knock characteristics of motor fuels in automotive engines under severe conditions of operation. The motor octane number provides a measure of the knock characteristics of aviation fuels in aviation piston engines, by using an equation to correlate to aviation-method octane number or performance number (lean-mixture aviation rating). This International Standard is applicable for the entire scale range from 0 MON to 120 MON, but the working range is 40 MON to 120 MON. Typical motor fuel testing is in the range of 80 MON to 90 MON. Typical aviation fuel testing is in the range of 98 MON to 102 MON. This International Standard is applicable for oxygenate-containing fuels containing up to 4,0 % (m/m) oxygen and for gasoline containing up to 25 % (V/V) ethanol.
Mineralölerzeugnisse - Bestimmung der Klopffestigkeit von Otto- und Flugkraftstoffen - Motor-Verfahren (ISO 5163:2014)
Diese Internationale Norm legt die Bewertung von flüssigen Kraftstoffen für Ottomotoren fest, angegeben nach einer willkürlich ausgewählten Skala von Octanzahlen, unter Anwendung eines genormten CFR-Motors (Einzylinder, Viertakt, variables Verdichtungsverhältnis, Vergaser), der mit konstanter Drehzahl betrieben wird. Die Motor-Octanzahl (MOZ) ist ein Maß für die Klopffestigkeit von Ottokraftstoffen für Automotoren unter schwierigen Betriebsbedingungen. In Bezug auf Flugkraftstoffe für Flugzeugkolbenmotoren bietet die Motor-Octanzahl ein Maß für die Klopffestigkeit, indem mithilfe einer Gleichung die Korrelation zur Octanzahl für den Flugbetrieb („aviation method“) bzw. zur Leistungszahl für den Flugbetrieb (Magergemischprüfung von Flugkraftstoff; „lean mixture aviation rating“) hergestellt wird.
Diese Internationale Norm ist anwendbar auf den gesamten Skalenbereich von 0 MOZ bis 120 MOZ, der Arbeitsbereich liegt jedoch zwischen 40 MOZ und 120 MOZ. Der typische Prüfbereich für Ottokraftstoffe beträgt 80 MOZ bis 90 MOZ. Der typische Prüfbereich für Flugkraftstoffe beträgt 98 MOZ bis 102 MOZ.
Diese Internationale Norm ist auf Kraftstoffe mit sauerstoffhaltigen Verbindungen mit einem Sauerstoffgehalt von bis zu 4 %(m/m) und für Ottokraftstoffe mit einem Ethanolgehalt von 25 % (V/V) anwendbar.
ANMERKUNG 1 Obwohl ein Ethanolgehalt von 25 % (V/V) etwa einem Sauerstoffgehalt von 9 %(m/m) entspricht, wurde die vollständige Anwendbarkeit dieser Prüfmethode für diesen Sauerstoffbereich nur für Ottokraftstoffe geprüft.
ANMERKUNG 2 Derzeit laufen Überprüfungen der Möglichkeit, das Verfahren auf Ottokraftstoffe mit einem Ethanolgehalt von bis zu 85 % (V/V) anzuwenden.
ANMERKUNG 3 Diese Internationale Norm legt Betriebsbedingungen in SI-Einheiten fest, die Maße des Motors können jedoch in Inch-Pound-Einheiten angegeben sein, da dies die Fertigungsmaße für die Ausrüstung waren; daher enthalten einige Verweisungen in dieser Internationalen Norm diese Einheiten in Klammern.
ANMERKUNG 4 Für die Anwendung dieser Norm werden die Ausdrücke „% (m/m)“ bzw. „% (V/V)“ verwendet, um Massenanteile in % () bzw. Volumenanteile in % () anzugeben.
Produits pétroliers - Détermination des caractéristiques antidétonantes des carburants pour moteurs et pour l'aviation - Méthode moteur (ISO 5163:2014)
L'ISO 5163:2014 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 moteur (MON) constitue une mesure des caractéristiques antidétonantes des carburants dans les moteurs pour automobiles dans des conditions de fonctionnement sévères. L'indice d'octane moteur constitue une mesure des caractéristiques antidétonantes des essences aviation dans les moteurs d'avion à pistons, en utilisant une équation pour le corréler à l'indice d'octane méthode aviation, ou indice de performance (indice aviation mélange pauvre).
L'ISO 5163:2014 s'applique dans une gamme d'indices d'octane allant de 0 MON à 120 MON, mais les essais courants se font entre 40 MON et 120 MON. La gamme de mesure classique pour les carburants moteurs va de 80 MON à 90 MON, tandis que pour les essences aviation elle va de 98 MON à 102 MON.
Naftni proizvodi - Določevanje oktanskega števila motornih in letalskih goriv - Motorna metoda (ISO 5163:2014)
Standard EN ISO 5163 vzpostavlja sistem vrednotenja tekočih motornih goriv z vžiganjem na iskro na podlagi arbitrarne lestvice oktanskih števil z uporabo enovaljnega štiritaktnega motorja CRF s spremenljivim kompresijskim razmerjem in uplinjačem, ki deluje pri konstantni hitrosti. Oktansko število po motorni metodi (MON) omogoča merjenje oktanskega števila motornih goriv v avtomobilskih motorjih pod ekstremnimi pogoji med delovanjem. Oktansko število po motorni metodi omogoča merjenje oktanskega števila letalskih goriv v letalskih batnih motorjih z uporabo enačbe za korelacijo z oktanskim številom po letalski metodi (lean-mixture aviation rating). Ta mednarodni standard velja za celotno lestvico od 0 MON do 120 MON, delovno območje pa je od 40 MON do 120 MON. Običajno preskušanje motornih goriv se izvaja v območju od 80 MON do 90 MON. Običajno preskušanje letalskih goriv se izvaja v območju od 98 MON do 102 MON. Ta mednarodni standard se uporablja za bencin z vsebnostjo oksigenatov, ki vsebuje do 4,0 % (m/m) kisika, in za bencin, ki vsebuje do 25 % (V/V) etanola.

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. www.iso.org/directives

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 2700-12. This International Standard is based on combining two former test
[1] [2]
methods for motor spark-ignition and aviation piston engine concepts
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 annexes and appendices of ASTM D 2700-12. 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 and aviation-type fuel data relating to knock characteristics determined in
many countries has, for many 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 and
1)
aviation-type fuels are defined by the motor method and associated CFR F-2 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 and aviation-type 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 2700 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 2700 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.
Due to identified component obsolescence issues, the original, analogue control panel has been replaced
by the manufacturer by the new digital panel. Service parts availability for the analogue system will be
[8]
phased out in the future. Research work was executed by ASTM International to check whether there
was statistically observable systemic bias between the 501C and the new digital knock measurement
system.
With respect to precision ISO and ASTM technical committees concluded that there was numerically
comparable precision for repeatability between the 501C and new panel knock measurement systems,
and no statistically observable difference for reproducibility between the 501C and new panel knock
measurement systems. For Motor octane number results, the evaluation detected neither a statistically
observable bias between the two systems nor sample-specific bias, so the results obtained by the two
knock measurement systems are practically equivalent (as obtained, no bias correction required). This
means that the new CFR octane panel could be included in the test method.

St. Paul Avenue, Waukesha, WI 53188, USA.

characteristics of motor and aviation fuels — Motor
method
WARNING — The use of this International Standard may involve hazardous materials, operations
and equipment. This International Standard does not purport to address 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 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. Motor octane number (MON)
provides a measure of the knock characteristics of motor fuels in automotive engines under severe
conditions of operation. The motor octane number provides a measure of the knock characteristics of
aviation fuels in aviation piston engines, by using an equation to correlate to aviation-method octane
number or performance number (lean-mixture aviation rating).
This International Standard is applicable for the entire scale range from 0 MON to 120 MON, but the
working range is 40 MON to 120 MON. Typical motor fuel testing is in the range of 80 MON to 90 MON.
Typical aviation fuel testing is in the range of 98 MON to 102 MON.
This International Standard is applicable for oxygenate-containing fuels containing up to 4,0 % (m/m)
oxygen and for gasoline containing up to 25 % (V/V) ethanol.
NOTE 1 Although 25 % (V/V) of ethanol corresponds to approximately 9 % (m/m) oxygen, full applicability of
this test method for that oxygen range has only been checked for gasoline type of fuels.
NOTE 2 Work is under way to check the possibility to use the method for gasoline containing up to 85 % (V/V)
ethanol.
NOTE 3 This International Standard specifies operating conditions in SI units but engine measurements may
be specified in inch-pound units because these were the units used in the manufacture of the equipment, and thus
some references in this International Standard include these units in parenthesis.
NOTE 4 For the purposes of this standard, the terms “% (m/m)” and “% (V/V)” are used to represent the mass
fraction, µ, and the volume fraction, φ, of a material respectively.
