Diesel fuel - Assessment of lubricity using the high-frequency reciprocating rig (HFRR) - Part 1: Test method (ISO 12156-1:2016)

ISO 12156-1:2016 specifies a test method using the high-frequency reciprocating rig (HFRR), for assessing the lubricating property of diesel fuels, including those fuels which may 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.

Carburant diesel - Évaluation du pouvoir lubrifiant au banc alternatif à haute fréquence (HFRR) - Partie 1: Méthode d'essai (ISO 12156-1:2016)

L'ISO 12156-1:2016 spécifié une méthode d'essai utilisant un banc alternatif à haute fréquence pour évaluer les propriétés lubrifiantes des carburants diesel, y compris les carburants qui peuvent 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 12156-1:2016)

Ta del standarda ISO 12156 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 dodatki, 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. www.iso.org/directives
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. Details of
any patent rights identified during the development of the document w
