Filter Patch Testing Procedures for Aerospace Hydraulic Pumps and Motors

CURRENT

ARP575B

This Aerospace Recommended Practice (ARP) sets forth recommendations of SAE Subcommittee A-6C (Fluid Power Distribution Elements) relative to the procedure and methods to be used in the obtaining and evaluation of filter patch tests for aerospace hydraulic pumps and motors. These patches are to be used in a quality control program to insure that units are operating properly prior to delivery to the customer. This is to promote an optimum in cleanliness standards in aerospace hydraulic circuits. It is expected that this will promote a longer service life of the pump or motor.

Hydrocarbon-Based Hydraulic Fluid Properties

2000-12-01

HISTORICAL

AIR81B

This document discusses the relative merits of the properties of hydrocarbon-based hydraulic fluid in relation to the fluid formulation, aerospace hydraulic system design and the related materials compatibility. In some cases, numerical limits are suggested, but, in general, the effect of a property is noted qualitatively. The properties of the fluid must be considered in the design of a hydraulic system, but it is possible to design a system to be less sensitive, or more robust, to a particular fluid property. For this reason, the property of the hydraulic fluid must be weighed for each individual hydraulic system, taking into account the system's basic design, function and environment, as well as the fluid toxicity and disposal issues. Besides the hydraulic system itself, ground handling and servicing needs of the system must also be considered. The only absolute characteristic of a hydraulic fluid is that it be a liquid throughout the range of use.
