This SAE Aerospace Recommended Practice (ARP) establishes a method for evaluating the particulate matter extracted from the working fluid of a hydraulic system or component using a membrane. The amount of particulate matter deposited on the membrane due to filtering a given quantity of fluid is visually compared against a standard membrane in order to provide an indication of the cleanliness level of the fluid
This AIR presents an abbreviated review of the metallurgical phenomena known as whiskers. It is not all encompassing; rather, it is intended to introduce the design engineer to the technical issues of metallic whiskers, their formation, and the potentially dangerous problems they can cause
This document presents minimum criteria for the design and installation of LED assemblies in aircraft. The use of "shall" in this specification expresses provisions that are binding. Nonmandatory provisions use the term "should
This SAE Recommended Practice is applicable for determining the cold characteristics of flexible plastic materials, as applicable. It consists of three different methods for determining low-temperature properties of materials depending on type of material and end use. The method used shall be as specified by the contractual parties
This specification covers a low-alloy steel in the form of bars, forgings, mechanical tubing, and forging stock
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
The chemistry identification system is intended to support the proper and efficient recycling of rechargeable battery systems used in transportation applications with a maximum voltage greater than or equal to 12 V. These applications include propulsion, starting/lighting/ignition, and providing power to other vehicle equipment. Other battery systems such as non-rechargeable batteries, batteries in electronics, and telecom/utility batteries are not considered in the development of this specification. This does not preclude these systems from adapting the format proposed if they so choose
This SAE Aerospace Recommended Practice (ARP) describes the concept of life cycle costing with emphasis on LCC techniques and applications as applied to the phases of the program cycle. These phases are: a Conceptual studies, research, development, test, and evaluation (RDT&E) b Investment, or procurement c Operating and support (O&S) or in-service d Disposal of systems, equipment, and services Cost elements, estimating techniques and other factors which have a bearing on LCCs are described; including use of cost estimating relationships (CER), simulation techniques, and "top-down"/"bottom-up" approaches. Consideration is also given to: a Risk and uncertainty assessments b Impact of economic variations including inflation, interest rates, and exchange rate variation c Adoption of discounting techniques when undertaking investment appraisals The use of tailored LCC models is preferred since there is an advantage in adopting a range of approaches particularly for the prediction of the
This SAE Standard covers the minimum requirements for a low-permeation tubing (100 g/m2/day or less) for use as a low pressure (14.5 kPa) liquid- or vapor-carrying component for use in gasoline or diesel fuel filler, vent, and vapor systems. The construction shall be designed to be functional over a temperature range of -40 to 100 °C for the T1 designation, or -40 to 125 °C for the T2 designation

This document provides design guidelines, test procedure references, and performance requirements for omnidirectional and selective coverage optical warning devices used on authorized emergency, maintenance, and service vehicles. It is intended to apply to, but is not limited to, surface land vehicles
This specification defines limits of variation for determining acceptability of the composition of cast or wrought titanium and titanium alloy parts and material acquired from a producer
This SAE Recommended Practice establishes a uniform procedure for assuring the manufactured quality, installed utility, and performance of automotive powered gas/brake controls other than those provided by the vehicle manufacturer (OEM). These products are intended to provide driving capability to persons with physical disabilities. These products function as adaptive modifications to compensate for lost or reduced function in the extremities of the driver. Powered gas/brake control systems are not only designed to transfer foot functions to the hands or from one side of the body to the other, but to supplement by power, other than by the driver’s own muscular efforts, the force output of the driver
This SAE Aerospace Recommended Practice (ARP) delineates two complementary filter element performance parameters: (1) dirt capacity, and (2) filtration efficiency, and corresponding test procedures. It is intended for non-cleanable (disposable), fine fuel filter elements, rated at 25 µm(c) or finer, used in aviation gas turbine engine fuel systems
This practice provides recommendations concerning the chemical milling of aluminum, magnesium, high temperature nickel alloys, titanium alloys, copper alloys, and specialty alloys
This test method provides a standardized procedure for evaluating the electrical resistance of automotive coolant hose covers. It is known that an electrical potential exists between the engine and the radiator. Coolant hose cover conductivity has been determined to be a factor to reduce hose clamp life when vehicle build variations allow possible contact of the hose or the clamp to metal components on the radiator and engine thus completing an electrical circuit. The ensuing electrical current can undercut the clamp protective coating, leaving it vulnerable to the corrosive effects of road salts, moisture, and other environmental contaminants. SAE Recommended Practice J1684 addresses the electrochemical resistance of the tube portion of the coolant hose
This SAE Aerospace Recommended Practice (ARP) provides recommendations for the design and test requirements for a spring-loaded, normally-closed hydraulic check valve.
