The work of preparing International
20、 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 organizations, governmental and non-governmental, in liaison with ISO, a
21、lso 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 its further maintenance are described in the ISO/IEC Directives, Part 1.
22、 In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2. www.iso.org/directivesThe main task of technical committees is to prepare International
23、Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.Attention is drawn to the possibility that some of the elements
24、 of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

30、ection 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 the fuel.The relationship of test results to diese
31、l 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 found to correlate with many fuel/hardware combinations
32、 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 permission of ASTM International, from ASTM Research Repor

It is the responsibility 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 metho
36、d 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.T

Nevertheless, no data has been presented to sugg

A fixed steel ball is held in a vertically mounted chuck and forced against a hori

The metallurgies of the ball and plate, test fluid temperature, load, frequency, stroke length, and the
47、ambient air conditions of temperature and humidity during the test are specified. The wear scar generated on the test ball is taken as a measure of the fluid lubricity.5 Reagents and materials5.1 Compressed air, if required for drying the equipment (8.1.1 and 8.1.2), supplied at a pressure of 140 kP
