適用范圍：This International Standard specifies procedures for the measurement of the extreme-pressure (EP) and antiwearproperties of lubricating oils and fluids by means of the four ball machine. The conditions of test arethose that apply in Europe and other areas that have similar electrical supply characteristics (200 V to 250 V,50 Hz). In North America, the conditions of test are slightly different, but provide a similar ranking of thelubricating properties of fluids. The test conditions are not intended to simulate particular service conditions,but to provide information over a range of standard conditions for the purpose of research, development, quality control and fluid ranking. The output is used in lubricant specifications.
