This supplement forms a part of SAE Aerospace Specification AS85421. It shall be used to identify fitting standards citing this procurement specification.
This SAE Standard establishes the test procedure, environment, and instrumentation for determining the sound levels of snowmobiles in the stationary test mode. This test method is intended to provide an accurate measurement of exhaust and other engine noise and may be used to evaluate new and in-use snowmobiles to determine compliance with noise control regulations. Sound level measurements obtained with this test method are not intended as an engineering determination of overall machine noise. For this purpose, the use of SAE J192 is recommended.
This specification covers a crosslinked polyvinyl chloride plastic in the form of flexible, thin-wall, heat-shrinkable tubing.
This SAE Recommended Practice describes the test procedures for conducting quasi-static cab roof strength tests for heavy-truck applications. Its purpose is to establish recommended test procedures that will standardize the procedure for heavy trucks. Descriptions of the test setup, test instrumentation, photographic/video coverage, and test fixtures are included.
This SAE Recommended Practice applies to all commercial, self-propelled motor vehicles which transport property or passengers when:
This SAE Standard provides minimum requirements and performance criteria for devices to prevent runaway snowmobiles due to malfunction of the speed control system.
Electric, Fuel Cell and Hybrid vehicles may contain many types of high voltage systems. Adequate barriers between occupants and the high voltage systems are necessary to provide protection from potentially harmful electric current and materials within the high voltage system that can cause injury to occupants of the vehicle during and after a crash. This SAE Recommended Practice is applicable to Electric, Fuel Cell and Hybrid vehicle designs that are comprised of at least one vehicle propulsion voltage bus with a nominal operating voltage greater than 60 and less than 1,500 VDC, or greater than 30 and less than 1,000 VAC. This Recommended Practice addresses post-crash electrical safety, retention of electrical propulsion components and electrolyte spillage.
This SAE Standard covers dimensional, material, and general specifications and methods of test for two types of general purpose conical spring washers, designated type L and type H, for use as loose washers over screws and bolts, and also for use as pre-assembled washers in screw and washer assemblies.
This test method outlines the standard procedure for measuring the radial and axial internal clearance of rolling element bearings used in airframe controls.
This SAE Recommended Practice covers a procedure for evaluating plastic and multiple-layer coatings exposed to gravelometer testing (as defined in SAE J400) with an optical imaging and analysis system. The intent of the procedure is to detect, count and characterize instances of damage in the coated surface that fracture the top coat layer or penetrate through multiple layers of the coating system. It may be possible to extend this methodology of coating damage evaluation to specimens that have undergone test procedures or exposures that produce similar, discrete damage sites in the coating system. If so applied, evaluation results must be interpreted with respect to the limitations and intent implied by the original evaluation procedure and its associated rating system, if applicable.
This SAE Recommended Practice pertains to liquid level determination for any fluid compartment of off-road work machines as defined in SAE J1116 and ISO 6165.
This specification covers a premium aircraft-quality maraging steel in the form of bars and forgings, 0.50 to 8.00 inches (12.7 to 203.2 mm) in nominal diameter or least distance between parallel sides, and forging stock of any size.
This SAE Recommended Practice provides the designer with guidance for the selection of directional control valves for use in the hydraulic systems of surface ships and submersibles. This guidance includes use of standard valves and interfaces, minimum envelopes that should be reserved to permit interchangeability, environmental considerations, and general technical requirements.
This standard defines the minimum requirements for conducting Measurement Systems Analysis (MSA) for variable and attribute assessment on characteristics as defined on the drawing or specification. It does not define the detailed analytical methods for each type of study as these can be found in existing published texts (see Section 2 for guidance).
This AIR provides a detailed example of the aircraft and systems development for a function of a hypothetical S18 aircraft. In order to present a clear picture, an aircraft function was broken down into a single system. A function was chosen which had sufficient complexity to allow use of all the methodologies, yet was simple enough to present a clear picture of the flow through the process. This function/system was analyzed using the methods and tools described in ARP4754A/ED-79A. The aircraft level function is “Decelerate Aircraft On Ground” and the system is the braking system. The interaction of the braking system functions with the aircraft are identified with the relative importance based on implied aircraft interactions and system availabilities at the aircraft level. This example does not include validation and verification of the aircraft level hazards and interactions with the braking system. However, the principles used at the braking system level can be applied at the
This SAE Standard serves as a guide for testing procedures of automotive 12 V storage batteries. The information contained herein was originally developed based on traditional ICE operation but can be more broadly applicable to other vehicle architectures. Although the test procedures contained herein are written from the standpoint of a 12 V nominal battery, they can be scaled for batteries with different nominal voltages.
The test procedures and performance criteria are directed to operation and parking of agricultural tractors equipped with braking system(s) and having a maximum design speed exceeding 6 km/h. Combinations of agricultural towing machines equipped with braking systems and towed agricultural machines without braking systems are included in this SAE Standard.
This procurement specification covers tubular-shaped, slotted spring pins made of a corrosion and moderate heat resistant, martensitic iron base alloy of the type identified under the Unified Numbering System as UNS S42000 and heat treated to permit flexure when inserted into a hole.
This specification covers requirements for the material, design, testing and packaging of straight thread tube fitting boss O-rings. O-rings covered by this specification are acrylonitrile-butadiene rubber.
This specification covers a low-alloy steel in the form of welding wire.
This SAE Standard specifies the general requirements and test methods for non-shielded, high-voltage ignition cable assemblies.
This specification covers established manufacturing tolerances applicable to titanium and titanium alloy extruded bars, rods, and shapes. These tolerances apply to all conditions, unless otherwise noted. The term “excl” applies only to the higher figure of the specified range.
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 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.
