It is the responsibility of users of this document to take appropriate measures to ensure the safety and health of personnel prior to the application of this document, and to determine the applicability of any other restrictions.This document specifies procedures for the measurement of the extreme pressure (EP) and anti-wear properties of liquid lubricants (categories C, D, F, G, H, M, P of ISO 6743-99), lubricating greases (ISO 6743-9, category X) and other consistent lubricants. 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.Cross References:ASTM D4057ISO 3170ISO 3290-1EN 10027ISO 6743-9ISO 4259ISO 6743-99All current amendments available at time of purchase are included with the purchase of this document.
