The ISO 12156-1 standard, developed by the International Organization for Standardization (ISO), describes a test method using a high-frequency reciprocating equipment (HFRR) to evaluate the lubricating properties of diesel fuels, including fuels containing a lubrication-enhancing additive. This standard provides two test methods for the measurement of wear marks:

Both test methods are valid for fuels used in diesel engines. However, it is not known whether these test methods will determine the performance of all additive and fuel combinations, including paraffinic fuels without additional correlation testing. However, there is no data that such fuels are not covered.
All diesel fuel injection equipment relies on diesel fuel as the lubricant. Wear from excessive friction, which causes short life of engine components such as diesel fuel injection pumps and injectors, is sometimes attributed to a lack of lubricity in the fuel.
Results from fuels tested according to these test methods are relevant to many fuel and equipment combinations and provide sufficient information regarding the lubrication quality of the fuel.
For the purposes of this document, the term boundary lubrication refers to a state where friction and wear between two surfaces in relative motion are determined by the properties of the surfaces and the properties of the contacting fluid, excluding bulk viscosity. Physically adsorbed or chemically reacted, usually very thin, soft films support contact loads. As a result, some wear is inevitable. The term lubricity is a concept that describes the ability of a fluid to affect friction and wear between surfaces in relative motion under load. In this test method, the lubricity of a fluid is assessed by the wear track produced on a ball released from contact with a stationary disk immersed in the fluid operating under controlled conditions.
