Diesel fuel - Assessment of lubricity using the high-frequency reciprocating rig (HFRR) - Part 1: Test method (ISO 12156-1:2018)

This document specifies a test method using the high-frequency reciprocating rig (HFRR), for assessing
the lubricating property of diesel fuels, including those fuels which could contain a lubricity-enhancing
additive. It defines two methods for measurement of the wear scar; Method “A” — Digital camera, and
Method “B” — Visual observation.
This test method applies to fuels used in diesel engines.
NOTE It is not known if this test method will predict the performance of all additive/fuel combinations,
including paraffinic fuels for which no additional correlation testing has been performed. Nevertheless, no data
has been presented to suggest that such fuels are not within scope.

Dieselkraftstoff - Bestimmung der Schmierfähigkeit unter Verwendung eines Schwingungsverschleiß-Prüfgerätes (HFRR) - Teil 1: Prüfverfahren (ISO 12156-1:2018)

Dieses Dokument legt ein Prüfverfahren unter Verwendung des Schwingungsverschleiß-Prüfgeräts (HFRR) zur Bewertung der Schmiereigenschaften von Dieselkraftstoffen und einschließlich von Kraftstoffen, die einen Zusatzstoff zur Verbesserung der Schmierfähigkeit enthalten können, fest. Dieser Teil legt zwei Verfahren für die Messung von Abriebkalotten fest; Verfahren „A“ — Digitalkamera und Verfahren „B“ — Sichtprüfung.
Dieses Prüfverfahren gilt für in Dieselmotoren verwendete Kraftstoffe.
ANMERKUNG   Es ist nicht bekannt, ob dieses Prüfverfahren die Leistung aller Kombinationen aus Additiven und Kraftstoffen einschließlich paraffinischer Kraftstoffe vorhersagt, für die keine zusätzliche Korrelationsprüfung durchgeführt wurde. Es liegen jedoch keine Daten vor, die vermuten lassen, dass diese Kraftstoffe nicht hiervon umfasst sind.

Carburant diesel - Évaluation du pouvoir lubrifiant au banc alternatif à haute fréquence (HFRR) - Partie 1: Méthode d'essai (ISO 12156-1:2018)

Le présent document spécifie une méthode d'essai utilisant un banc alternatif à haute fréquence pour évaluer les propriétés lubrifiantes des carburants diesel, y compris les carburants qui pourraient contenir un additif améliorant le pouvoir lubrifiant. Elle définit deux méthodes pour mesurer les dimensions de la marque d'usure: Méthode A ? Appareil photo numérique, et Méthode B ? Observation visuelle.
Cette méthode d'essai est applicable aux carburants utilisés dans les moteurs diesel.
NOTE       Il n'est pas établi que cette méthode d'essai estimera la performance de toutes les combinaisons additifs/carburants, dont les gazoles paraffiniques pour lesquels aucun essai supplémentaire pour établir une corrélation n'a été réalisé. Néanmoins, aucune donnée n'a été présentée qui puisse suggérer que ce type de carburant n'entre pas dans le domaine d'application de cette méthode.

Dizelsko gorivo - Ocenjevanje mazalne sposobnosti z visokofrekvenčnim merilnikom (HFRR) - 1. del: Preskusna metoda (ISO 12156-1:2018)

Ta dokument določa preskusno metodo z uporabo visokofrekvenčnega merilnika (HFRR) za ocenjevanje mazalne sposobnosti dizelskih goriv, vključno z gorivi, ki lahko vsebujejo dodatek za večanje mazalne sposobnosti. Opisuje dve metodi za merjenje obrabne ploskve, in sicer metodo A z digitalnim snemanjem in metodo B z opazovanjem.
Ta preskusna metoda se uporablja za goriva v dizelskih motorjih.
OPOMBA: Ni znano, ali bo ta preskusna metoda napovedala lastnosti vseh kombinacij dodatkov/goriva, vključno s parafinskimi gorivi, za katera ni bilo opravljeno dodatno korelacijsko preskušanje. Kljub temu niso bili predstavljeni nobeni podatki, ki bi kazali, da takšna goriva niso zajeta.

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 (see www .iso .org/directives).

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. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www .iso .org/patents).

This fourth edition of ISO 12156-1 cancels and replaces the third edition (ISO 12156-1:2016), which has

been technically revised after a user feedback survey. This revision includes the following changes:

— lessening of the requirements on reagents and correction of the ambient test conditions (Figure 2)

to reflect the actual conditions met by participants in the inter-laboratory test program;

— the Annex containing details of the major changes (adding the camera and deletion of the humidity

correction factor) between the second and third edition of this document has been removed; and

— Annex A has been populated with updated photographs of typical wear scars.

Introduction

All diesel fuel injection equipment has some reliance on diesel fuel as a lubricant. Wear due to excessive

friction resulting in shortened life of engine components, such as diesel fuel injection pumps and

injectors, has sometimes been ascribed to lack of lubricity in the fuel.

The relationship of test results to diesel injection equipment component distress due to wear has been

demonstrated for some fuel/hardware combinations where boundary lubrication is a factor in the

operation of the component .

Test results from fuels tested to this procedure have been found to correlate with many fuel/hardware

combinations and provide an adequate prediction of the lubricating quality of the fuel. The correlation

of biodiesel blends has been validated through 15 years of field experience and anecdotal data.

boundary lubrication

condition in which the friction and wear between two surfaces in relative motion are determined by

the properties of the surfaces and the properties of the contacting fluid, other than bulk viscosity

Note 1 to entry: Metal to metal contact occurs and the chemistry of the system is involved. Physically adsorbed

or chemically reacted soft films (usually very thin) support contact loads. As a result, some wear is inevitable.

3.2
lubricity

qualitative term describing the ability of a fluid to affect friction between, and wear to, surfaces in

relative motion
