Diesel fuel - Assessment of lubricity using the high-frequency reciprocating rig (HFRR) - Part 1: Test method (ISO 12156-1:2023)
This document specifies a test method using the high-frequency reciprocating rig (HFRR) with a digital camera, for assessing the lubricating property of petroleum-based middle distillate fuels, paraffinic diesel fuels, and biodiesel blends, with or without lubricity enhancing additives, and with HFRR wear scar diameters (WSDs) of 350 μm to 700 μm.
This test method applies to fuels used in diesel engines.
NOTE It is not known if this test method can predict the performance of all additive/fuel combinations.

Carburant diesel - Évaluation du pouvoir lubrifiant au banc alternatif à haute fréquence (HFRR) - Partie 1: Méthode d'essai (ISO 12156-1:2023)
Le présent document spécifie une méthode d'essai utilisant un banc alternatif à haute fréquence (HFRR) pour évaluer à l’aide d’un appareil photo numérique les propriétés lubrifiantes des carburants diesel, des carburants diesel paraffiniques et des mélanges biodiesel, avec ou sans additif améliorant de pouvoir lubrifiant, et avec des diamètres de marque d’usure (WSD) HFRR compris entre 350 μm et 700 μm.
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.
Dizelsko gorivo - Ocenjevanje mazalne sposobnosti z visokofrekvenčnim merilnikom (HFRR) - 1. del: Preskusna metoda (ISO 12156-1:2023)
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 – digitalno snemanje in metodo B – opazovanje.
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 document 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).
