2、oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S.Department o
3、f Defense.1NOTEEditorially corrected Fig.3 in July 2020.1.Scope*1.1 This test method covers assessment of the wear aspectsof the boundary lubrication properties of aviation turbine fuelson rubbing steel surfaces.1.1.1 This test method incorporates two procedures,oneusing a semi-automated instrument
4、and the second a fullyautomated instrument.Either of the two instruments may beused to carry out the test.1.2 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.3 This standard does not purport to address the safetyconcerns,if any
5、,associated with its use.It is the responsibilityof the user of this standard to establish appropriate safety,health,and environmental practices and determine the appli-cability of regulatory limitations prior to use.1.4 This international standard was developed in accor-dance with internationally r
