Scope1.1 This guide covers information to assist in the selectionof a method for measuring the frictional properties of materi-als. Requir

3、ements for minimum data and a format for present-ing these data are suggested. The use of the suggested reportingform will increase the long-term usefulness of the test resultswithin a given laboratory and will facilitate the exchange oftest results between laboratories. It is hoped that the use of

4、auniform reporting format will provide the basis for the prepa-ration of handbooks and computerized databases.1.2 This guide applies to most solid materials and to mostfriction measuring techniques and test equipment.1.3 UnitsThe values stated in SI units are to be regardedas standard. No other unit

Summary of Guide4.1 Current ASTM International friction test standards aretabulated in this guide so that users can review available tes

25、tmethods and determine which method may be most applicablefor a particular application. Any of the listed tests or otheraccepted test may be used. General friction testing precautionsare cited and a prescribed method of recording friction data isrecommended. This guide is intended to promote the use

26、 of thisstandard reporting system and standard friction test methods.4.2 The use of one of the test methods (Table 1) cited in thisguide will give assurance of a testing procedure that has beenagreed-to for a particular application. In addition, it is impor-tant to keep in mind that friction is a sy

27、stem property. Thecoefficient of friction of polystyrene on mild steel measured ona sled test (Test Method D1894) will probably be different thanthe coefficient of the same couple measured on a block-on-ringtester (Test Method G176) since the coeffcient of friction is asystem effect.4.3 Data develop

Conformance with this guide in testing and reportingshould produce data that can be reviewed for applicability to aparticular tribosystem.5. Significance and Use5.1 In this guide, factors

29、 that shall be considered in con-ducting a valid test for the determination of the coefficient offriction of a tribosystem are covered, and the use of a standardreporting format for friction data is encouraged.5.2 The factors that are important for a valid test may not beobvious to non-tribologists,

30、 and the friction tests referencedwill assist in selecting the apparatus and test technique that ismost appropriate to simulate a tribosystem of interest.5.3 The tribology literature is replete with friction data thatcannot readily be used by others because specifics are notpresented on the tribosys

Their use will significantly reduce theneed for each la
