Diesel fuel — Assessment of lubricity using the high-frequency reciprocating rig (HFRR) — Part 1: Test method
Edition 5
2023-09
2023-09
Abstract
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.
