25、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

26、 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

28、ectivesThe main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.

35、SO 12156-1:2016 (E) IntroductionAll diesel fuel injection equipment has some reliance on diesel fuel as a lubricant. Wear due to excessive friction resulting in shortened life of engine components, such as diesel fuel injection pumps and injectors, has sometimes been ascribed to lack of lubricity in

36、 the fuel.The relationship of test results to diesel injection equipment component distress due to wear has been demonstrated for some fuel/hardware combinations where boundary lubrication is a factor in the operation of the component.1)Test results from fuels tested to this procedure have been foun

37、d to correlate with many fuel/hardware combinations and provide an adequate prediction of the lubricating quality of the fuel. The correlation of biodiesel blends has been validated through 15 years of field experience and anecdotal data.This part of ISO 12156 includes content and data, with permiss

This part of ISO 12156 does not purport to address all of the safety problems associated with its use. It is the r

40、esponsibility of the user of this part of ISO 12156 to establish appropriate safety and health practices, and determine the applicable regulatory limitations prior to use.1 ScopeThis part of ISO 12156 specifies a test method using the high-frequency reciprocating rig (HFRR), for assessing the lubric

41、ating 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.NOTE It is not known

42、if this test method will predict the performance of all additive/fuel combinations, 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.2 Normative referencesThe following

47、o surfaces in relative motion are determined by the properties of the surfaces and the properties of the contacting fluid, other than bulk viscosityNote 1 to entry: Metal to metal contact occurs and the chemistry of the system is involved. Physically adsorbed or chemically reacted soft films (usuall

As a result, some wear is inevitable.3.2lubricityqualitative term describing the ability of a fluid to affect friction between, and wear to, surfaces in relative motion under loadNote 1 to entry: In this test method, the lubricity of a fluid is evaluated by the wear scar, measured in micrometres, produced on an oscillating ball from contact with a stationary disk immersed in the fluid operating under closely controlled conditions.3.3wear scar diameterWSDmean diameter of the wear scar produced on the test ball4 PrincipleA sample of the fluid under test is
