ISO 20623:2017规定了液体润滑剂（ISO 6743-99的C、D、F、G、H、M、P类）、润滑脂（ISO 6743-9，X类）和其他一致润滑剂的极压（EP）和抗磨性能的测量程序。试验条件不是为了模拟特定的使用条件，而是为了研究、开发、质量控制和流体分级提供一系列标准条件的信息。输出用于润滑油规格。

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.
