Description / Abstract:
This Recommended Practice defines a procedure, which will aid in
assessing the contaminant wear characteristics of hydraulic
components. This procedure utilizes a very high level of
contaminant that permits an accelerated test to determine the wear
effects of contamination in a relatively short period. This
recommended practice utilizes the contamination sensitivity test
circuit identified in SAE J2470.
This procedure does not establish contamination wear
requirements for any hydraulic component. The user of this
procedure needs to be aware of the system contamination level that
the component will operate in and select test contamination levels
significantly higher than the operating level in order to assess
the suitability of the component.
