This SAE Aerospace Recommended Practice (ARP) covers the design, construction, performance and testing requirements for hand held aircraft tire inflation pressure gauges with valve stem attachment chuck to be used with all aircraft types. The ground-based gauges in this specification are those which are designed to read the tire inflation pressure from a position adjacent to the tire
This specification covers the general design, testing, and safety requirements for aircraft tank mounted fuel booster pumps used for engine fuel feed, transfer, and jettison
This document establishes performance, material, and design requirements and design guidelines for halogen replaceable light sources used in road illumination devices for forward lighting. Non-halogen filament light sources suitable for forward lighting are specified in SAE J573. The terms “high beam filament” and “low beam filament” used throughout this document refer only to typical use, not to a mandatory, exclusive, or universal function of the filaments. This SAE Recommended Practice is periodically updated to keep pace with experience and technical advances
This SAE Aerospace Information Report (AIR) contains regulatory and guidance information related to airplane wheels, tires, and brakes. It contains certain Civil Air Regulations (CAR) and Federal Aviation Regulations (formerly referred to as FARs) from Title 14 Code of Federal Regulations (CFR) in their current version as well as the historical versions. This gives the reader an ability to assemble certain CAR/CFR parts as they existed at any date in the past (referred to as a Regulatory Basis). A certain amount of preamble explanatory material is included, which led to the regulatory rule changes (Amendments to the CFR
This SAE Recommended Practice is intended as the definition of a standard test, but may be subject to frequent change to keep pace with experience and technical advances. This should be kept in mind when considering its use. The SAE No 2 Friction Test Machine is used to evaluate the friction characteristics of automatic transmission plate clutches with automotive transmission fluids. It can also be used to conduct durability tests on wet friction systems. The specific purpose of this document is to define a Durability Test based on a specific power level selected from either the 3600 r/min Stepped Power Test or from the 6000 r/min Stepped Power Test, for the evaluation of wet friction system performance variation as a function of number of cycles. This standard procedure is intended for common use by both suppliers and end users to allow objective comparisons of wet friction material system performance. The only variables selected by the supplier or user of the friction system are: a
This Standard is restricted to refrigeration circuits that provide air-conditioning for the passenger compartments of passenger and commercial vehicles. This Standard includes analytical and physical test procedures to evaluate refrigerant concentration inside the passenger compartment. In the early phases of vehicle evaluation, usage of the analytical approach may be sufficient without performing physical tests. The physical test procedure involves releasing refrigerant from an external source to a location adjacent to the evaporator core (inside the HVAC module). An apparatus is used to provide a repeatable, calibrated leak rate. If the system has multiple evaporators, leakage could be simulated at any of the evaporator locations. This standard gives detail information on the techniques for measuring R-744 (CO2) and R-1234yf (HFO-1234yf), but the general techniques described here can be used for other refrigerants as well
This SAE Standard encompasses connectors between two cables or between a cable and an electrical component and focuses on the connectors external to the electrical component. This document provides environmental test requirements and acceptance criteria for the application of connectors for direct current electrical systems of 50 V or less in the majority of heavy-duty applications typically used in off-highway machinery. Severe applications can require higher test levels, or field-testing on the intended application
Common or obvious surface imperfections, which sometimes occur in sheet steel, are normally visible to the naked eye before or after fabrication. Illustrations and definitions of these imperfections are contained in this SAE Information Report. The identifying names are those commonly used throughout the steel industry. The imperfections identified include the major and most often encountered imperfections known to exist at this time. These imperfections are variable in appearance and severity. Extreme conditions have been selected in some instances in order to obtain suitable photographs.

This SAE Recommended Practice describes the classification of off-road tires and rims for use on construction machines (see SAE J1116), defines related terminology in common use, and shows representative construction details of component parts
This SAE Recommended Practices specifies a procedure for determining structural strength and fatigue life of disc-brake caliper assemblies which are satisfactory for vehicle usage. It is applicable to new caliper assemblies which are employed in passenger car and truck brake systems utilizing hydraulic brake fluids. Brake design and vehicle performance requirements are not included. Specification limits are left to the discretion of the responsible manufacturer. This procedure was developed for base brake operation and does not consider some unusual effects of ABS (Anti-Lock-Brake System) or Traction Control systems which may have a significant effect on the caliper. Careful analysis of the particular type ABS and/or Traction Control should be made and additional tests may be required which are not included in this document
This SAE Standard covers the mechanical and material requirements for eight property classes of steel, externally threaded metric fasteners in sizes M1.6 through M36, inclusive, and suitable for use in automotive and related applications
This SAE Recommended Practice provides a method for testing the speed performance of light truck tires under controlled conditions in the laboratory on a test wheel
The intent of the specification is to present a functional set of requirements which define the user and hardware interfaces while providing sufficient capability to meet the misfire patterns for compliance demonstration and engineering development. Throughout this requirement, any reference to “ignition or injector control signal” is used interchangeably to infer that the effected spark ignition engine’s ignition control signal or the compression ignition engine’s injector control signal is interrupted, timing phased, or directly passed by the misfire generator. For spark ignition engines, the misfire generator behaves as a spark-defeat device which induces misfires by inhibiting normal ignition coil discharge. It does so by monitoring the vehicle’s ignition timing signals and suspends ignition coil saturation for selected cylinder firing events. The misfire generator will thereby induce engine misfire in spark ignited gasoline internal combustion engines; including rotary engines
This SAE Recommended Practice establishes uniform procedures for evaluating conformity between the actual and target drive speeds for chassis dynamometer testing utilizing standard fuel economy and emissions drive schedules
SAE J2600 applies to the design and testing of Compressed Hydrogen Surface Vehicle (CHSV) fueling connectors, nozzles, and receptacles. Connectors, nozzles, and receptacles must meet all SAE J2600 requirements and pass all SAE J2600 testing to be considered as SAE J2600 compliant.
