Dynamic Standards

This SAE Aerospace Standard (AS) provides dimensions for a standardized test fixture that can be used to evaluate the dynamic performance requirements defined in some elastomer material standards of O-rings in rod glands per AS4716.

5.1 Dynamic cushioning test data obtained by this test method are applicable to the cushioning material and not necessarily the same as obtained in a package. In addition to the influence of the package, the data can also be affected by the specimen area, thickness, loading rate, and other...

5.1 This test method calibrates or demonstrates conformity of a dynamic mechanical analyzer at an isothermal temperature within the range of -100 °C to 300 °C. 5.2 Dynamic mechanical analysis experiments often use temperature ramps. This method does not address the effect of that...

1.1 This test method covers the assignment of a glass transition temperature (Tg) of materials using dynamic mechanical analyzers. 1.2 This test method is applicable to thermoplastic polymers, thermoset polymers, and partially crystalline materials which are thermally stable in the glass...

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...

1.1 This is a compilation of only those terms and corresponding definitions included in or being considered for inclusion in ASTM documents relating to thermophysical properties. It is not intended as an all-inclusive listing of thermophysical property terms. Terms that are generally understood or...

1.1 This test method covers the measurement of the penetration rate of the dynamic cone penetrometer with an 8 kg [17.6 lb] hammer (8 kg [17.6 lb] DCP) through undisturbed soil or compacted materials, or both. The penetration rate may be related to in situ strength such as an estimated in...

5.1 Predicting the viscosity of a blend of components is a common problem. Both the Wright Blending Method and the ASTM Blending Method, described in this practice, may be used to solve this problem. 5.2 The inverse problem, predicating the required blend fractions of components to meet a specified...

5.1 This test method provides a standard for comparison of wind vanes of different types. Specifications by regulatory agencies and industrial societies (3-5) have stipulated performance values. This test method provides an unambiguous method for measuring starting threshold, delay distance, and...

1.1 This test method covers the determination of corrosion-preventive properties of greases using grease-lubricated ball bearings under dynamic wet conditions. 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...

1.1 This test method covers quantitative procedures for the evaluation of the compatibility of automotive engine oils with several reference elastomers typical of those used in the sealing materials in contact with these oils. Compatibility is evaluated by determining the changes in volume,...

This SAE Aerospace Specification (AS) is applicable to all aircraft. This AS defines the minimum design and operating requirements for the aircraft refueling interface. These requirements establish the minimum criteria for the aircraft design that provides practical standardized refueling system...

This SAE Aerospace Standard (AS) specifies solid, un-cut polytetrafluoroethylene (PTFE) retainers (backup rings) for use in glands in accordance with AS4716. They are usually used in hydraulic and pneumatic system components as anti-extrusion devices in conjunction with O-rings and other seals for...

This SAE Recommended Practice describes an evaluation procedure for validating tire models for use in road load simulations and assesses the relevant dynamic behavior of tires. The laboratory test utilized is a "cleat" test, where a rolling tire on a drum encounters a cleat and the resulting...

This SAE Aerospace Information Report (AIR) addresses many of the significant issues associated with effects of inlet total-pressure distortion on turbine-engine performance and stability. It provides a review of the development of techniques used to assess engine stability margins in the presence...

4.1 Use this test method to obtain a quantitative value indicating the rate of moisture vapor emission from the surface of a concrete floor and whether or not that floor is acceptable to receive resilient floor covering. The moisture vapor emission rate only reflects the condition of the concrete...

1.1 This test method covers the determination of corrosion-preventive properties of greases using grease-lubricated ball bearings under dynamic wet conditions. 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...

1.1 The purpose of this test method is to provide specifications for the hydraulic testing of full-scale articulating concrete block (ACB) revetment systems under controlled laboratory conditions for purposes of identifying stability performance in steep slope, high-velocity flows. The testing...

1.1 This practice covers a uniform procedure for radioscopic examination of castings. Radioscopic examination of weldments can be found in E1416. 1.2 This practice applies only to radioscopic examination in which an image is finally presented on a display screen (monitor) for evaluation. Test part...
