External Standards

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...

The objective of this glossary is to establish uniform definitions of parts and terminology for engine cooling systems. Components included are all those through which engine coolant is circulated: water pump, engine oil cooler, transmission and other coolant-oil coolers, charge air coolers, core...

1.1 This specification2 covers the requirements for seamless copper and copper alloy tubing on which the external or internal surface, or both, has been modified by a cold-forming process to produce an integral enhanced surface for improved heat transfer. 1.2 The tubes are typically used in...

This specification covers reinforced plastic pipe and fitting system made from epoxy resin and glass-fiber reinforcement, together with adhesive for joint assembly, intended for services in aviation jet turbine fuel lines installed below ground. The fiberglass pipe shall be round and straight, and...

This SAE Recommended Practice establishes the test procedure, environment, and instrumentation to be used for measuring the exterior exhaust sound level for passenger cars, multipurpose vehicles, and light trucks under stationary conditions providing a continuous measure of exhaust system or...

This document is intended to satisfy the data reporting requirements of standardization regulations in the United States and Europe, and any other market that may adopt similar requirements in the future. This document specifies: a Message formats for request and response messages. b Timing...

4.1 The purpose of this standard practice is to provide the minimum requirements for the conduct of compliance audits. 4.2 The intended use of this practice is to provide a basis for an internal or external entity to develop an audit program. An audit program defines specific requirements...

1.1 This practice covers the design of buried precast concrete low head pressure pipe having a circular shape and manufactured in accordance with Specification C361/C361M subject to internal pressure not exceeding a pressure head of 125?ft (54?psi), or as otherwise limited herein. 1.2 When buried,...

1.1 These test methods cover the determination of the purity of present commercially available rubber chemical accelerators in the range from 80?% to 100?% by high performance liquid chromatography (HPLC) using ultraviolet detection and external standard calculations. 1.2 Expertise in HPLC...

1.1 This test method covers the purity of Type I, II, and III p-phenylenediamine (PPD) antidegradants as described in Classification D4676 by high performance liquid chromatography (HPLC) using ultraviolet detection and external standard calculations. 1.2 Expertise in HPLC is necessary to...

097410-000000-000000 1 Scope 1.1 The requirements of this standard apply to off-board unidirectional and bidirectional equipment rated 1000 Vac and 1500 Vdc or less, that transfers electrical energy between an electric vehicle and off board loads as well as operating in parallel with an electric...

This specification covers the materials, sizing, and manufacturing details of test headforms for use in the testing of protective headgear. This specification identifies the requirements for five test headform size codes: A, E, J, M, and O. All datum levels shall be quoted relative to the reference...

1.1 This test method is commonly referred to as the John Deere Cavitation Test.2 The test method defines a heavy-duty diesel engine to evaluate coolant protection as related to cylinder liner pitting caused by cavitation. 1.2 The values stated in SI units are to be regarded as the standard. The...

5.1 This test method is suitable for setting specifications on the materials referenced in Table 1 and for use as an internal quality control tool where cyclohexane is produced or is used in a manufacturing process. It may also be used in development or research work involving cyclohexane. 5.2 This...
