Petroleum products - Determination of knock characteristics of motor fuels - Research method (ISO 5164:2014)
EN ISO 5164 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. This International Standard 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. 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 Ottokraftstoffen - Research-Verfahren (ISO 5164:2014)
Diese Internationale Norm legt die Bewertung von flüssigen Kraftstoffen für Ottomotoren fest, angegeben nach einer willkürlich ausgewählten Skale von Octanzahlen, unter Anwendung eines genormten CFR-Motors (Einzylinder, Viertakt, variables Verdichtungsverhältnis, Vergaser), der mit konstanter Drehzahl betrieben wird. Die Research-Octanzahl (ROZ) ist ein Maß für die Klopffestigkeit von Ottokraftstoffen für Automotoren unter leichten Betriebsbedingungen.
Diese Internationale Norm ist anwendbar auf den gesamten Skalenbereich von 0 ROZ bis 120 ROZ, der Arbeitsbereich liegt jedoch zwischen 40 ROZ und 120 ROZ. Der typische Prüfbereich für Ottokraftstoffe beträgt 88 ROZ bis 101 ROZ.
Diese Internationale Norm ist auf Kraftstoffe mit sauerstoffhaltigen Verbindungen mit einem Gehalt an Sauerstoff von bis zu 4,0 % (m/m) auf Ottokraftstoffe mit einem Gehalt von bis zu 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 dieses Prüfverfahrens für diesen Sauerstoffbereich nur für Ottokraftstoffe geprüft.
ANMERKUNG 2 Derzeit laufen Überprüfungen der Möglichkeit, das Verfahren auf Ottokraftstoffe mit einem Gehalt an Ethanol von bis zu einschließlich 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.
ANMERKUNG 1 Derzeit laufen Überprüfungen der Möglichkeit, das Verfahren auf Ottokraftstoffe mit einem Gehalt an Ethanol von bis zu 85 % (V/V) anzuwenden.
Bestimmte Gase und Dämpfe, wie z. B. halogenierte Kühlmittel aus Klimaanlagen, die in der Umgebung des CFR-Motors anwesend sein können, können eine messbare Auswirkung auf die ROZ-bezogene Bewertung haben. Elektrische Einschwingspannungen bzw. Frequenzstörungen oder -verzerrungen können die ROZ-bezogenen Bewertungen ebenfalls beeinflussen.
ANMERKUNG 2 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 3 Für die Anwendung dieser Norm werden die Ausdrücke „% (m/m)“ bzw. „% (V/V)“ verwendet, um Massenanteile in % (μ) bzw. Volumenanteile in % (ϕ) anzugeben.
Produits pétroliers - Détermination des caractéristiques antidétonantes des carburants pour moteurs - Méthode de recherche (ISO 5164:2014)
L'ISO 5164:2014 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 recherche (RON) constitue une mesure des caractéristiques antidétonantes des carburants dans les moteurs pour automobiles dans des conditions de fonctionnement peu sévères.
L'ISO 5164:2014 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 5164:2014 est applicable aux carburants qui comportent des oxygénés et contiennent au maximum 4,0 % (m/m) d'oxygène et aux essences contenant jusqu'à 25 % (V/V) d'éthanol.
Naftni proizvodi - Določevanje oktanskega števila motornih goriv - Raziskovalna metoda (ISO 5164:2014)
Standard EN ISO 5164 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 raziskovalni metodi (RON) omogoča merjenje oktanskega števila motornih goriv v avtomobilskih motorjih pod blagimi pogoji delovanja. Ta mednarodni standard velja za celotno lestvico od 0 RON do 120 RON, delovno območje pa je od 40 RON do 120 RON. Običajno preskušanje motornih goriv se izvaja v območju od 88 RON do 101 RON. 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 2699-12.
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 in every detail requires reference to annexes and appendices of ASTM D 2699-12. 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 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 fuels are defined by the research
1)
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.
For these reasons, it has been considered desirable by ISO Technical Committee 28, Petroleum products
and lubricants, to adopt the ASTM D 2699 standard procedures. 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 available
from ASTM International.
Due to identified component obsolescence issues, the original, analogue control panel has been replaced
by the manufacturer by new digital panel as of 2011. Service parts availability for the analogue system
[5]
will be 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. This means that the new CFR octane panel could be included in the test method.
1) The sole manufacturer of the Model CFR F-1 Octane Rating Unit is Waukesha Engine, Dresser Waukesha,
Inc., 1000 West St. Paul Avenue, Waukesha, WI 53188, USA.

characteristics of motor fuels — Research 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. Research octane number
(RON) provides a measure of the knock characteristics of motor fuels in automotive engines under mild
conditions of operation.
This International Standard 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.
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 up to and including 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.
