Title:Hydraulic Fluid Power - Accelerated Method for Determining the Wear Characteristics of a Hydraulic Component Due to Contaminants
Issuing Committee:Ship Fluid Systems Committee
Scope:1. Scope.1.1 This Recommended Practice defines a procedure, which will aid in assessing the contaminant sensitivity of hydraulic components. This procedure utilizes a very high level of contaminant that permits an accelerated test to determine the affects of contamination in a relatively short period. This recommended practice utilizes the contamination sensitivity test circuit and contaminants identified in SAE J2470.1.2 This procedure does not establish contamination sensitivity 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 that the operating level in order to assess the suitability of the component.
