Hydraulic Motor Test Procedures
2009-06-12
HISTORICAL
J746_200906
This test code describes tests for determining characteristics of hydraulic positive displacement motors as used on construction and industrial machinery as referenced in SAE J1116. These characteristics are to be recorded on data sheets similar to the one shown in Figure 1. Two sets of data sheets are to be submitted: one at 49 °C (120 °F) and one at 82 °C (180 °F).

Hydraulic Directional Control Valves, 3000 psi Maximum
2019-12-04
CURRENT
J748_201912
This SAE Recommended Practice has been set up by Subcommittee 4 of the Off-Road Machinery Technical Committee and is primarily for directional control valves on construction and industrial machinery equipment as referenced in SAE J1116. The purpose is to establish port area to flow relationship and match valve spool eye ends in relation to rated capacity. Port connections are optional for either the 4-bolt split flange connection or the internal straight thread "O" ring connection.

HYDRAULIC CONTROL VALVE TEST PROCEDURE
1986-03-01
HISTORICAL
J747_198603
This procedure describes laboratory tests for establishing operating characteristics of hydraulic directional control valves used on mobile industrial and construction equipment as referenced in SAE J1116. These characteristics are to be recorded on data sheets similar to those shown herein. Two sets of data are to be submitted--one at 122°F (50°C) and one at 194°F (90°C). A separate set of data sheets is to be submitted for the cylinder ports closest to, and farthest from the inlet and outlet ports of a multiple section valve.

HISTORICAL
J747B_197410
This SAE Standard applies to hydraulic directional control valves as applied to self-propelled work machines referenced in SAE J1116. It describes a laboratory test procedure for evaluating: a.) Flow versus pressure drop, b.) Leakage rate, c.) Operating effort, d.) Metering characteristics versus spool travel, pilot pressure, or electrical current, e.) Relief valve characteristics. This 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.

ASSESSING CLEANLINESS OF HYDRAULIC FLUID POWER COMPONENTS AND SYSTEMS
1979-06-01
HISTORICAL
J1227_197906
To describe laboratory methods for determining and reporting the contaminant level of the wetted portion of hydraulic fluid power components, parts, subsystems and systems, and of fill fluids. For each type of item it provides a method of obtaining the liquid sample and the contamination level thereof. It also includes procedures for establishing a sampling plan and guidelines for establishing levels of acceptance, but does not set those levels.
