Petroleum and related products. Determination of the extreme-pressure and anti-wear properties of lubricants. Four-ball method (European conditions) Ingestion-build-63436 BS EN ISO 26782 applies1 Scope 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 674399), lubricating greases (ISO 67439, 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
