Welded and Cold-Drawn, High Strength (690 MPa Tensile Strength) Low Alloy Steel Hydraulic Tubing, Stress Relieved Annealed for Bending, Flaring, Cold Forming and Brazing

2018-06-15
CURRENT
J2833_201806
This specification covers stress relieved annealed electric resistance welded and cold-drawn single-wall high strength low alloy steel tubing intended for use in hydraulic pressure lines and in other applications requiring tubing of a quality suitable for bending, flaring, cold forming, and brazing. The grade of material produced to this specification is of micro-alloy content. Nominal reference working pressures for this tubing are listed in ISO 10763 and SAE J1065. CAUTION: Sub-critically annealed steels are often produced using anneal temperatures below the Lower Critical Temperature (AC1) of the given steel to achieve the desired strength levels. Welding, brazing, or other processing methods that subject the tube material or assembly to temperatures near or above AC1 might initiate isothermal transformation of the tube microstructure and compromise the strength of the tube in the heat affected zone by further annealing the tube.

Standard for Fuel Systems in Fuel Cell and Other Hydrogen Vehicles

2018-06-15
CURRENT
J2579_201806
The purpose of this document is to define design, construction, operational, and maintenance requirements for hydrogen fuel storage and handling systems in on-road vehicles. Performance-based requirements for verification of design prototype and production hydrogen storage and handling systems are also defined in this document. Complementary test protocols (for use in type approval or self-certification) to qualify designs (and/or production) as meeting the specified performance requirements are described. Crashworthiness of hydrogen storage and handling systems is beyond the scope of this document. SAE J2578 includes requirements relating to crashworthiness and vehicle integration for fuel cell vehicles. It defines recommended practices related to the integration of hydrogen storage and handling systems, fuel cell system, and electrical systems into the overall Fuel Cell Vehicle.

Taxonomy and Definitions for Terms Related to Driving Automation Systems for On-Road Motor Vehicles

2018-06-15
CURRENT
J3016_201806
This SAE Recommended Practice describes motor vehicle driving automation systems that perform part or all of the dynamic driving task (DDT) on a sustained basis. It provides a taxonomy with detailed definitions for six levels of driving automation, ranging from no driving automation (level 0) to full driving automation (level 5), in the context of motor vehicles (hereafter also referred to as “vehicle” or “vehicles”) and their operation on roadways. These level definitions, along with additional supporting terms and definitions provided herein, can be used to describe the full range of driving automation features equipped on motor vehicles in a functionally consistent and coherent manner.

WIP
AIR1539C
This publication will be limited to a discussion of liquid and particulate contaminants which enter the aircraft through the environmental control system (ECS). Gaseous contaminants such as ozone, fuel vapors, sulphates, etc., are not covered in this AIR. It will cover all contamination sources which interface with ECS, and the effects of this contamination on equipment. Methods of control will be limited to the equipment and interfacing ducting which normally falls within the responsibility of the ECS designer.

Air Conditioning Systems for Subsonic Airplanes

2018-06-14
WIP
ARP85G
This SAE Aerospace Recommended Practice (ARP) contains guidelines and recommendaitons for subsonic airpolane air conditioning systems and components, including requirements, design philosophy, testing and ambient conditions. The airplane air conditioning system comprises that arrangement of equipment, controls and indicators that supply and distribute air to the occupied compartments for ventilation, pressurization, and temperature and moisture control. The principal features of the system are: a. A supply of fresh air from at least two sources with independent control valves b. A means for heating c. A means for cooling (air or vapor cycle units and heat exchangers) d. A means for removign excess moisture from the air supply e. A ventilation subsystem f. A temperature control subsystem g.

Performance Specification for Welded Wire-to-Wire Splices

2018-06-14
CURRENT
USCAR45
SAE/USCAR-45 defines test methods and performance requirements for ultrasonically-welded wire-to-wire splices for automotive applications. Face-to-face, butt splice, and center strip configurations per Figure 1 can be tested. The tests defined in this specification subject samples on test to stresses that simulate a lifetime of exposure for a road vehicle. Stresses called out in this specification include thermal shock, temperature/humidity cycling and mechanical stress from different directions.

Recommended Practice for Pass-Thru Vehicle Programming

2018-06-14
WIP
J2534/1
This SAE Recommended Practice describes a standardized interface that connects between a standard personal computer (PC) and vehicle. The purpose of this interface is to enable the reprogramming of emission-related control modules, in 2004 and later model year vehicles. The interface shall consist of the necessary hardware and/or software to support the requirements defined in this document. It is expected that vehicle manufacturers will provide the software application that will control the Pass-Thru Interface, to perform the actual reprogramming. The goal of this document is to ensure that reprogramming software from any vehicle manufacturer is compatible with interface supplied by any tool manufacturer. A common interface for all vehicle manufacturers reduces the tool costs for aftermarket garages, while allowing each vehicle manufacturer to control the programming sequence for the electronic control units (ECUs) in their vehicles.

Gland Design: Nominal 3/8 in Cross Section for Custom Compression Type Seals

2018-06-13
WIP
AS4832A
This SAE Aerospace Standard (AS) offers gland details for a 0.364 cross section gland (nominal 3/8 in) with proposed gland lengths for compression type seals with two backup rings over a range of 8 to 20 in diameter. A dash number system is proposed similar to AS568A. A 600 series has been chosen as a logical extension of AS568A and the 625 number has been arbitrarily chosen for the initial number. (Both 300 and 400 series begin with 325 and 425 sizes.) Seal configurations and design are not a part of this document. This gland is for use with custom compression type seals including, but not limited to, O-rings, T-rings, D-rings, etc.
