Hydraulic Fluid Power - Accelerated Method for Determining the Wear Characteristics of a Hydraulic Component Due to Contaminants
J2890_201006
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.
Rationale:
SAE J2470 provides a test procedure to identify the sensitivity of valves to sticking or degraded performance due to contaminants but does not identify or measure the wear characteristics of hydraulic components due to contaminants. Some standards have attempted to predict the wear characteristics over the life of the component but often do not standardize the contaminants and are costly to run because of their long duration. This Recommended Practice provides an accelerated procedure to determine the wear characteristics of various hydraulic components by using the SAE J2470 test apparatus with a very high level of contaminants that permits testing and comparison of designs in a relatively short time.
