Hydraulic Standards

Applies to hydraulic cylinders which are components of Off-Road Self-Propelled Work Machines defined in SAE J1116.

This document describes hydraulic fluids used in landing gear shock struts with extreme high contact pressure and anti-wear additives that have been added for improved lubrication.

The purpose of this SAE Aerospace Recommended Practice (ARP) is to provide a practical definition of external hydraulic fluid leakage exhibited by landing gear shock absorbers/struts. The definition will outline normal (acceptable weepage) and excessive leakage (unacceptable leakage) of...

1.1 These test methods cover the chemical analyses of hydraulic cements. Any test methods of demonstrated acceptable precision and bias may be used for analysis of hydraulic cements, including analyses for referee and certification purposes, as explained in Section 4. Specific...

1.1 This test method covers the rapid determination of hydraulic activity of slag cement. This test method measures the accelerated strength development of the slag cement by using sodium hydroxide solution as mixing water and curing at elevated temperature. 1.2 The values stated in SI units...

This SAE Standard covers steel wire reinforced rubber hose assemblies using connectors specified in SAE J516 for use in hydraulic systems using petroleum based hydraulic fluids with maximum working pressures of 1.7 to 42 MPa. See Part 2, Table 7 for hose operating temperature ranges...

1.1 This performance specification covers hydraulic cements for both general and special applications. There are no restrictions on the composition of the cement or its constituents (see Note 1). Note 1: There are two related hydraulic cement standards, Specification C150/C150M for...

This SAE Standard covers general and dimensional specifications for the Code 62 metric (Type 1) and inch (Type 2) flanged heads, flange clamps (FC and FCM), and split flange clamps (FCS and FCSM) applicable to four-screw flange type tube, pipe, and hose connections. Also included are the...

This SAE Standard gives methods for testing and evaluating performance of the SAE 100R series of hydraulic hose and hose assemblies (hose and attached end fittings) used in hydraulic fluid power systems. Specific tests and performance criteria for evaluating hose assemblies used in...

This specification pertains to blended hydraulic cements for both general and special applications, using slag or pozzolan, or both, with portland cement or portland cement clinker or slag with lime. These cements are classified into two types: Type IS which is portland blast-furnace slag...

This part of SAE J514 covers general and dimensional specifications for NPTF pipe adapters and 30 degree NPSM adapter unions. These fittings are intended for general application in hydraulic systems on industrial equipment and commercial products. These fittings are capable of providing...

This specification covers an ethylene propylene rubber in the form of molded rings, molded compression seals, molded O-ring cord, and molded-in-place gaskets for aeronautical and aerospace applications.

5.1 This guide discusses ways to assess the likelihood that a hydraulic fluid will undergo biodegradation if it enters an environment that is known to support biodegradation of some substances, for example the material used as the positive control in the test. The information can be used in...

This Aerospace Recommended Practice (ARP) establishes uniform requirements and procedures to determine the torsional strength of permanent hydraulic tube joints. It also establishes testing equipment and apparatus for torsion testing.

1.1 This specification is for rapid hardening hydraulic cements. This is a specification giving performance requirements. There are no restrictions on the composition of the cement or its constituents. 1.2 The specification classifies cements by type based on specific requirements for very...

1.1 This test method2 is designed primarily to evaluate the thermal stability of hydrocarbon based hydraulic oils although oxidation may occur during the test. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3...

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...

This document provides recommended practices for the design and selection of tube, hose, and fitting systems that are used to transmit hydraulic fluid on aircraft. NOTE: Guidance for the sizing of hydraulic tubing is contained in Appendix A .
