This SAE Aerospace Recommended Practice (ARP) provides guidance for the verification and certification of a “commercial” fixed wing aircraft fuel tank inerting system (FTIS) and will provide technical references and data regarding ground and flight testing of an FTIS. The intent of this ARP is to address issues associated with the verification requirements based on current regulatory guidance per AC25.981-2C
This SAE Standard J3072 establishes interconnection requirements for a utility-interactive inverter system which is integrated into a plug-in electric vehicle (PEV) and connects in parallel with an electric power system (EPS) by way of conductively-coupled, electric vehicle supply equipment (EVSE). This standard also defines the communication between the PEV and the EVSE required for the PEV onboard inverter to be configured and authorized by the EVSE for discharging at a site. The requirements herein are intended to be used in conjunction with IEEE 1547 Standard for Interconnecting Distributed Resources with Electric Power Systems and IEEE 1547.1 Standard for Conformance Test Procedures for Equipment Interconnecting Distributed Resources with Electric Power Systems.
This ARP provides recommended practice on the considerations and methodology to demonstrate acceptable performance of the Engine components / fuel system, and APU, whilst operating throughout the flight cycle / engine duty for continuous operation with iced fuel and short duration operation with a snowshower resulting from release of accreted ice from fuel washed surfaces, where no anti-icing additives are present (e.g. Fuel System Icing Inhibitor FSII or alternative). Two scenarios must be considered when demonstrating the capability of Engine components / fuel system, and APU to operate with fuel borne ice to satisfy certification regulations applications in support of FAA Part 23 and Part 25, CFR Part 33, and corresponding EASA CS-E regulations, and equivalent Military application requirements.
This SAE Information Report J2836/5™ establishes the use cases for communications between Plug-In Electric Vehicles (PEV) and their customers.

This Aerospace Recommended Practice (ARP) recommends fuel booster pump design requirements commensurate with the presently known state-of-the-art, relating to the prevention of autogenous ignition of explosive fuel vapors and the confinement of autogenous or spark-initiated flames by means of flame-suppressing devices.
This document presents the requirements for a build-in service port to be used in vehicles intended to comply with Enhanced Evaporative Emission Requirements. The primary function of the Service Port (Valve Assembly-Evaporative Emission Canister Purge Harness Service) is to provide non-destructive access to the evaporative emissions system to enable testing of the integrity of the system. The Service Port is used to introduce air pressure or fuel vapors into, or evacuate them out of, the system. This access may be used for the following evaluations: Evaporative System Certifications Canister Loading and Pumping End-of-line Testing System Integrity Service (e.g. OBD MIL on) Leak Location and Repair Verification In-Use Compliance Testing Canister Loading and Purging Inspection/Maintenance Testing System Integrity and Purge Check
Dispenser Nozzle Spouts for Liquid Fuels Intended for Use With Spark Ignition and Compression Ignition Engines
This SAE recommended practice provided standard dimensions for liquid fuel dispenser nozzle spouts and a system for differentiating between nozzels that dispense liquid fuel into vehicles with Spark Ignition (SI) Engines and compression Ignition (CI) Engines for land vehicles. Current legal definitions only distinguish between "UNLEADED Fuel" and "All Other Types of Fuel." These definitions are no longer valid. This document establishes a new set of definitions that have practical application to current automobile liquid fuel inlets and liquid fuel dispenser nozzle spouts.
This Aerospace Information Report (AIR) is intended to provide comprehensive reference and background information pertaining to aircraft point level sensing
This SAE Aerospace Recommended Practice (ARP) provides to the aerospace industry a procedure for the consistent and accurate calculation of fuel flow using turbine flowmeters during development, production, and post overhaul/repair gas turbine engine testing.
This test method is intended for measuring fuel permeation at elevated temperature through low permeating hose or tubing samples of elastomeric or composit construction. The expected accuracy of the method is about +/- 10% of the sample permeation rate.
Methods for Determining Physical Properties of Polymeric Materials Exposed to Hydrocarbon Fuels or Their Surrogates and Their Blends with Oxygenated Additives
This SAE Recommended Practice applies to determining worst-case fuel, conditioning test specimens in worst-case fuel(s) prior to testing, individual tests for properties of polymers exposed to methanol-gasoline fuel mixtures. The determination of equilibrium, as well as typical calculations are also covered. Polymers are used in applications which require exposure to a variety of fluid environments. Tests to determine the effects of such exposure on material properties are well established. However, the determination of the effects on polymers exposed to fuels of variable alcohol and ether content poses new problems. This document seeks to address those concerns by detailing changes to standard tests that make them suitable for that purpose.
This section presents the basic equations for computing ice protection requirements for nontransparent and transparent surfaces and for fog and frost protection of windshields. Simplified graphical presentations suitable for preliminary design and a description of various types of ice, fog, frost, and rain protection systems are also presented.
The mass of air required to burn a unit mass of fuel with no excess of oxygen or fuel left over is known as the stoichiometric air-fuel ratio. This ratio varies appreciably over the wide range of fuels - gasolines, diesel fuels, and alternative fuels - that might be considered for use in automotive engines. Although performance of engines operating on different fuels may be compared at the same air-fuel ratio or same fuel-air ratio, it is more appropriate to compare operation at the same equivalence ratio, for which a knowledge of stoichiometric air-fuel ratio is a prerequisite. This SAE Recommended Practice summarizes the computation of stoichiometric air-fuel ratios from a knowledge of a composition of air and the elemental composition of the fuel without a need for any information on the molecular weight of the fuel.
SCOPE IS UNAVAILABLE.
This recommended practice covers minimum requirements for air brake hose assemblies made from reinforced elastomeric hose and suitable fittings for use in automotive air brake systems including flexible connections from frame to axle, tractor to trailer, trailer to trailer and other unshielded air lines with air pressures up to 1 MPa, that are exposed to potential pull or impact. This hose is not to be used where temperatures, external or internal, fall outside the range of -40 °C to +100 °C.
The intent of this document is to develop a recommended practice for PEV chargers, whether on-board or off-board the vehicle, that will enable equipment manufacturers, vehicle manufacturers, electric utilities and others to make reasonable design decisions regarding power quality. The three main purposes are as follows: 1. To identify those parameters of PEV battery charger that must be controlled in order to preserve the quality of the AC service. 2. To identify those characteristics of the AC service that may significantly impact the performance of the charger. 3. To identify values for power quality, susceptibility and power control parameters which are based on current U.S. and international standards. These values should be technically feasible and cost effective to implement into PEV battery chargers. SAE J2894/2 Power Quality Requirements for Plug-In Electric Vehicle Chargers – Test Methods will describe the test methods for the parameters / requirements in this document.
SAE J2601 establishes the protocol and process limits for hydrogen fueling of light duty vehicles. These process limits (including fuel temperature, the maximum fuel flow rate, and rate of pressure increase and end pressure) are affected by factors such as ambient temperature, fuel delivery temperature and initial pressure in the vehicle’s compressed hydrogen storage system. SAE J2601-2014 establishes standard fueling protocols based on a look-up table approach with performance targets. The current standard is table-based and provides concise performance targets for both communications and non-communications fueling as described in Sections 7 through 10. An important factor in the performance of hydrogen fueling is the station’s dispensing equipment cooling capability and the resultant fuel delivery temperature “T” rating. SAE J2601 has a reference fueling target of 3 minutes with 95-100% SOC (with communications) with a T40 rated dispenser as specified in section 6.1.
Classification of Energy Conserving Engine Oil and Resource Conserving Engine Oil for Passenger Cars, Vans, Sport Utility Vehicles, and Light-Duty Trucks

Effective August 28, 1991, the SAE replaced the USCG as the listing agency for Marine Hose Assemblies. The previous USCG list was discontinued as of December 31, 1992, and is being replaced by this SAE listing, J1942-1. All products appearing on the USCG list as of December 31, 1992, may be carried over to the SAE J1942-1 provided they meet the new test requirements listed in SAE J1942. If your products comply, you may retain your listings with no additional testing. (Please note that the USCG has the authority to request and inspect your test results at their discretion.) The following list consists of hose data provided as of May 2003, and is for convenience in determining acceptability of nonmetallic flexible hose assemblies intended for usage under 46 CFR 56.60-25(c). Where the maximum allowable working pressure (MAWP) or type of fitting is not specified, use the manufacturer's recommended MAWP or type of fitting.
This method is designed to evaluate the coking propensity of synthetic ester-based aviation lubricants under single phase flow conditions found in certain parts of gas turbine engines, for instance in bearing feed tubes. This method is applicable to lubricants with a coking propensity, as determined by this method, falling in the range 0.01 to 3.00 mg.
This SAE Standard defines the limits for a classification of engine lubricating oils in rheological terms only. Other oil characteristics are not considered or included.
This specification defines basic physical, chemical, and performance limits for 5 cSt grades of gas turbine engine lubricating oils used in aero and aero-derived marine and industrial applications, along with standard test methods and requirements for laboratories performing them. It also defines the quality control requirements to assure batch conformance and materials traceability, and the procedures to manage and communicate changes in oil formulation and brand. This specification invokes the Performance Review Institute (PRI) product qualification process. Requests for submittal information may be made to the PRI at the address in Appendix C, referencing this specification. Products qualified to this specification are listed on a Qualified Products List (QPL) managed by the PRI. Additional tests and evaluations may be required by individual equipment builders before an oil is approved for use in their equipment.
This SAE Technical Information Report (TIR) provides test methods for evaluating hydrogen sensors when the hydrogen system integrator and/or vehicle manufacturer elect to use such devices on board their hydrogen or fuel cell vehicles. The test methods are performance-based using environmental and operating conditions defined in SAE J2578. Since the use of the on-board hydrogen sensors is not standardized or regulated, the implementation of these sensors can vary greatly from vehicle to vehicle. In general, the test methods considered the widest reasonable range of operating conditions based on different possible sensor implementations within the vehicle. For example, the on-board sensor could be located in relatively dry environments like the passenger compartment or in “damp” environments such as the process exhaust from the fuel cell system.
Standard Test Procedure and Limit Value for Shutoff Surge Pressure of Pressure Fuel Dispensing Systems
