Long wave ultraviolet or UV-A irradiation (between 320 and 400 nm) is used for fluorescent inspections in magnetic particle and liquid penetrant examinations. UV-A irradiation is obtained from either LED, fluorescent, or high intensity discharge lamps that are stationary or portable. Commercially available UV-A lamps possess a large variation in intensity output that may introduce a legitimate concern for possible health hazards. This document reviews the nature of UV-A irradiation emitted by lamps and acceptable UV dosage limits adopted by the American Conference of Governmental Industrial Hygienists (ACGIH®) and European Union and recommendation of proper practices when working with UV-A irradiation.
This method is intended to evaluate the thermal and oxidative stability of synthetic, ester-based aviation lubricants under defined conditions of time and temperature. This method is applicable to lubricants meeting the compositional and performance requirements of AS5780.
This specification covers the installation of aircraft interior lighting for military aircraft.
This document provides recommendations to identify battery group sizes and dimensions for 6 V, 8 V, 12 V, and 24 V lead acid batteries.
This specification covers a manganese alloy in the form of powder, preforms, and a viscous mixture (paste) of the powder in a suitable binder.
This specification establishes the procedures used to produce a hard anodic coating on magnesium alloys and the properties of the coating.
This specification covers a corrosion-resistant steel in the form of sheet, strip, and plate.
This SAE Standard applies to 12-volt lead-acid storage batteries that are designed specifically for start-stop operations in on-road passenger vehicles or light trucks. Included are definitions of terms, general testing recommendations, key performance characteristics, and life testing. Properties not unique to start-stop batteries should be tested according to SAE J537 or other applicable testing protocols.
This document outlines general requirements for the use of CFD methods for aerodynamic simulation of medium and heavy commercial ground vehicles weighing more than 10000 pounds. The document provides guidance for aerodynamic simulation with CFD methods to support current vehicle characterization, vehicle development, vehicle concept development, and vehicle component development. The guidelines presented in the document are related to Navier-Stokes and Lattice-Boltzmann based solvers. This document is only valid for the classes of CFD methods and applications mentioned. Other classes of methods and applications may or may not be appropriate to simulate the aerodynamics of medium and heavy commercial ground vehicle weighing more than 10000 pounds.
This Aerospace Standard (AS), establishes minimum performance standards for those sensors, computers, transponders, and airplane flight deck controls/displays which together comprise a Takeoff Performance Monitor (TOPM) System. This standard also defines functional capabilities, design requirements, and test procedures. A TOPM system is intended to monitor the progress of the takeoff and to provide advisory information which the crew may use in conjunction with other available cues to decide to continue or abort the takeoff. See Appendix A for supplementary information relating to NTSB, CAA, and ad hoc committee concerns and background information.
This standard only defines interconnect, electrical and logical (functional) requirements for the interface between a Micro Munition and the Host. The physical and mechanical interface between the Micro Munition and Host is undefined. Individual programs will define the relevant requirements for physical and mechanical interfaces in the Interface Control Document (ICD) or system specifications. It is acknowledged that this does not guarantee full interoperability of Interface for Micro Munitions (IMM) interfaces until further standardization is achieved.
This SAE Recommended Practice describes the dynamic testing procedures required to evaluate the integrity of patient compartment interior Storage Compartments such as cabinets, drawers, or refillable supply pouch systems when exposed to a frontal, side or rear impact (i.e., a crash impact). Its purpose is to provide component manufacturers, ambulance builders, and end-users with testing procedures and, where appropriate, acceptance criteria that, to a great extent, ensure interior Storage Compartments or systems meet the same performance criteria across the industry. Descriptions of the test set-up, test instrumentation, photographic/video coverage, test fixture, and performance metrics are included.
This SAE Standard covers the mechanical and physical requirements for Compacted Graphite Iron (CGI) castings used in automotive and allied industries. Requirements in this document include: a Tensile Strength b Yield Strength c Elongation d Graphite Morphology
This SAE Standard covers the mechanical and material requirements for three grades of steel nuts suitable for use in automotive and related engineering applications, in sizes 1/4 to 1-1/2 inches, inclusive, and with dimensions conforming with the requirements of the latest issue of SAE J482 or ASME B18.2.2, except for machine screw nuts which are not covered in this standard. This document does not include limits for surface discontinuities. Where usage requires such control, limits may be specified separately. For sizes 1/4 through 1 inch, this may be done by the statement: “Surface discontinuities shall not exceed the limits specified in ASTM F812/F812M.”
This document establishes techniques for validating that an Aircraft Station Interface (ASI) complies with the interface requirements delineated in MIL-STD-1760B Notice 3. For validation of aircraft designed to MIL-STD-1760A Notice 2 AS4764 Issued 1995-04 applies.
This SAE Aerospace Information Report (AIR) provides details of how to perform hydraulic system calculations using equations that incorporate the metric International System of Units (SI).
This specification covers a premium aircraft-quality alloy steel in the form of welding wire.
This specification covers a silicone (MQ/VMQ) elastomer that can be used to manufacture product in the form of sheet, strip, tubing, extrusions, and molded shapes. This specification should not be used for molded rings, compression seals, O-ring cord, and molded-in-place gaskets for aeronautical and aerospace applications, AMS7268 should be used.
This SAE Aerospace Recommended Practice (ARP) is a guide for defining the requirements for aerospace piston hydraulic accumulators, including details pertinent to the design, fabrication, performance and testing of the accumulator. This type of accumulator contains a piston which separates pressurized gas and fluid.
This specification covers a corrosion-resistant steel in the form of investment castings.
The following schematic diagrams reflect various methods of illustrating automotive transmission arrangements. These have been developed to facilitate a clear understanding of the functional interrelations of the gearing, clutches, hydrodynamic drive unit, and other transmission components. Two variations of transmission diagrams are used: in neutral (clutches not applied) and in gear. For illustrative purposes, some typical transmissions are shown.
This SAE Aerospace Standard (AS) establishes the requirements for pipe threaded fluid connection fittings (see Section 6) for use in all types of fluid systems.
