ISO 20623:2017 Preview

Petroleum and related products -- Determination of the extreme-pressure and anti-wear properties of lubricants -- Four-ball method (European conditions)

ISO 20623:2017 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.
