These products have been used in contact with air and a wide variety of fuels, lubricants, specific hydraulic fluids, and a variety of gas turbine engine lubricants, including higher thermo-oxidative stability (HTS) lubricants, including those conforming to MIL-PRF-23699 Class HTS, MIL-PRF-7808 Grade 4, and AS5780 Class HPC; however, usage is not limited to such applications. This material type has a typical service temperature range of -20 to +400 °F (-28 to +204 °C). These products are not suitable for use in phosphate ester based hydraulic fluids. Each application should be considered individually.

This material type has resistance to hot air, but generally has poor resistance to fuels and lubricants, but usage is not limited to such applications. Each application should be considered separately. This material type has a typical service temperature range of -85 to 500 °F (-65 to 260 °C). The operating temperature range of the material is a general temperature range, but the presence of particular fluids and design parameters may modify this range. Recommendations on the material selection are based on available technical data and are offered as suggestions only. Each user should make his own tests to determine the suitability for his own particular use.

The purpose of this fuel filter test method is to provide standardized methods for evaluating the performance characteristics of fuel filters by bench test methods. This, combined with data obtained from application tests, may be used to establish standards of performance for filters when tested by these standard methods. Many variations in requirements of filtration to protect fuel supply equipment on engines and variations in operating conditions make it difficult to specify meaningful "in-service" performance standards by which a filter may be judged. By the use of these standard test methods, test conditions are always the same, and comparisons of the laboratory performance of filters may be made with a high degree of confidence. Once the requirements of a particular application are known, performance standards for suitable filters may be established by these test methods, and adequacy of performance of filters for the job may be determined.

In order to achieve the highest degree of reliability of test results, the procedures and equipment must conform to those specified in this code. No minimum performance requirements for filters have been specified, since these are the responsibility of the user and manufacturer. Only the methods of determining, interpreting, and reporting performance characteristics are the proper province of this SAE Standard.

Separate chapters cover the test methods necessary to evaluate the several functional capabilities and mechanical properties of the filter. Each chapter is complete with recommended materials, apparatus, and procedures for testing and evaluation. The chapters are:

1. a
   Chapter 1—Resistance to Flow (Section 3)
2. b
   Chapter 2—Filter Capacity and Contaminant Removal Characteristics (Section 4)
3. c
   Chapter 3—Media Migration Test (Section 5)
4. d
   Chapter 4—Collapse Test (Section 6)

6. f
   Chapter 6—Installation and Removal (Section 8)
7. g
   Chapter 7—Mechanical Tests (Section 9)
8. h
   Chapter 8—Material Compatibility (Section 10)

To simplify the chapters covering test methods, information of importance but not directly involved in test methods is covered in appendices as follows:

This coding system is intended to provide a convenient means of identifying the various tube, pipe, hydraulic hose type and hose fittings, not intended for use in aircraft and of transmitting technical or engineering information relating to them wherever drawings or other pictorial media may not be readily available. The code has been kept flexible to permit expansion to cover new fitting categories or styles and, if the need develops, the inclusion of additional materials. The system is also compatible with automatic data processing equipment.

It is not intended that this code should supersede established systems or means of identification. Therefore, it should be the prerogative of the user to apply the code which best satisfies his requirements.

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:

The 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.

Performance characteristics such as metering hysteresis or dynamic response may have a significant effect on some of these tests.

This SAE Standard covers specifications and performance requirements for 37 degree and 45 degree single and double flares for tube ends intended for use with SAE J512, SAE J513, SAE J514, and ISO 8434-2 connectors. The flares described in this document are intended for use with SAE metallic tube materials. Considerations such as the effects of wall thickness selection for specific working pressures, identifying appropriate length of thread engagements for specific applications with mating connectors and other associated criteria, shall be the responsibility of the user. For applicable nominal reference working pressures for hydraulic tubing, refer to SAE J1065 and ISO 10763.

In an effort to standardize within a global marketplace and ensure that companies can remain competitive in an international market, it is the intent of this document to promote the use of metric tube and connector sizes, which will:
