EVS-EN ISO 20623:2018

This document specifies procedures for the measurement of the extreme-pressure (EP) and antiwear 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 testing conditions are those that apply in Europe and other areas that have similar electrical supply characteristics (200 V to 250 V, 50 Hz). 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.
NOTE Application of this test using electrical supply characteristics other than those noted in the Scope is possible when it is ensured that a corresponding power supply, transformer or regulator is used such that voltages and frequencies are converted inside the apparatus to ensure compliance with the conditions of the Scope during actual testing.
High temperatures can potentially evolve during testing; therefore, it is necessary to take special precautions to avoid boiling when water-containing products are being tested. If a suitable temperature control is not possible, water-containing fluids shall not be tested using this test method.
