BS EN ISO 12156-1:2023

This standard BS EN ISO 12156-1:2023 Diesel fuel. Assessment of lubricity using the high-frequency reciprocating rig (HFRR) is classified in these ICS categories:

• 75.160.20 Liquid fuels

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 ?m to 700 ?m. 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.
