Annex A (informative) Measurement of HFRR wear scars
This part of ISO 12156 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.
NOTEIt is not known if this test method will predict the performance of all additive/fuel combinations. NUEVO: 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.
