This SAE Standard applies to hydraulic directional control valves as applied to self-propelled workmachines referenced in SAE J1116. It describes a laboratory test procedure for evaluating:a. Flow versus pressure dropb. Leakage ratec. Operating effortd. Metering characteristics versus spool travel, pilot pressure, or electrical currente. Relief valve characteristicsThe document applies to single and multiple section hydraulic directional control valves.This document illustrates axial, manually operated valves although the test procedure is applicable to other input forms such as rotary actuation, electric current, hydraulic or pneumatic pressure.NOTE—Performance characteristics such as metering hysteresis or dynamic response may have asignificant effect on some of these tests.1.1 Purpose—To provide a uniform procedure for measuring and reporting the operating characteristics of a hydraulic directional control valve and associated relief valve when so equipped.
