Nuts, Self-Locking, UNS N07001 730 °C, 1100 MPa, and 1210 MPa Procurement Specification for, Metric
2024-05-09
CURRENT
MA1943C
This procurement specification covers aircraft quality self-locking nuts for wrenching (hex, spline) and anchor (plate, gang channel, shank) types of nuts made from a corrosion and heat-resistant nickel-base alloy of the type identified under the Unified Numbering System as UNS N07001. Tension height nuts having overall length of threaded portion not less than 1.2 times the nominal thread diameter have 1210 MPa minimum tensile strength at room temperature. Shear height nuts having shorter threaded portion have 1100 MPa minimum tensile strength at room temperature. Maximum test temperature of parts is 730 °C.

Standard Four-Letter Coding as an Identification Method for Alternative Fuel Vehicles
2024-05-07
WIP
J3108/1
SAE J3108 RP provides fuel and hazard guidance for first and second responders of incidents associated with alternative fueled vehicles. The intent of this SAE J3108-1 RP is to remain with the limited number of seven intuitive and colored letters contained in each of the first two letter positions (72=49). However, the use of four letters plus nine digits (to not use either 0 or o) permits up to 1185921 unique identifiers (334) for future expansion. The RP is not intended to replace the standards for SAE J2990 format emergency response guide (ERG) created by automotive manufacturers for use at the scene of an emergency. Automotive OEMs are encouraged to reference this RP for industry design guidance when creating vehicle requirements and ERGs. This coding should be consistent with other vehicle badging with the goal of providing additional clarity.

Lubricant, Cetyl Alcohol, 1-Hexadecanol, Application to Fasteners
2024-05-01
CURRENT
AS87132A
This specification establishes the requirements for flake or granular cetyl alcohol, solvents for dissolving the cetyl alcohol, preparation and application requirements for use of cetyl alcohol as an installation lubricant on mechanical fasteners, such as pins, bolts, nuts, washers, threaded or nonthreaded fastening devices, and inspection criteria for coated parts.

Titanium Alloy Bars, Forgings, and Flash-Welded Rings, 5Al - 2.5V - 4Sn - 1Co - 0.8Fe Annealed
2024-04-25
CURRENT
AMS6903
This specification covers a titanium alloy in the form of bars, forgings, and flash-welded rings up through 12.000 inches (304.80 mm), inclusive, in diameter or least distance between parallel sides, and stock of any size for forging or flash-welded rings. Bars, forgings, and flash-welded rings with a nominal thickness of 3.000 inches (79.20 mm) or greater shall have a maximum cross-sectional area of 113 square inches (729 cm2) (see 8.5).

Liquid Leak Tightness Evaluation Methodology for EV Battery Packs Informational Report
2024-04-23
CURRENT
J3277_202404
This technical information report (IR) presents a methodology to evaluate battery pack liquid leak tightness attributes to be used in a production line to satisfy the functional requirement for IPX7, water ingress requirement, and no sustainable coolant leakage for coolant circuits. The Equivalent Channel Method is used as a suggested production leak tightness requirement for a given battery pack design that will correlate and assure that the battery pack meets or exceeds its functional requirement. Obtaining the specific geometry of the Equivalent Channel (EC) for a given battery pack is done analytically and empirically in consideration of the product design limitations. This document is a precursor to J3277-1, which will present the practices to qualify that product leak tightness is equal or better than the maximum allowed EC for that product using applicable and commercially available leak test technologies.

Electric Vehicle Power Transfer System Using Conductive Automated Connection Devices
2024-04-23
WIP
J3105
This document covers the general physical, electrical, functional, testing, and performance requirements for conductive power transfer, primarily for vehicles using a conductive ACD connection capable of transferring DC power. It defines conductive power transfer methods, including the infrastructure electrical contact interface, the vehicle connection interface, the electrical characteristics of the DC supply, and the communication system. It also covers the functional and dimensional requirements for the vehicle connection interface and supply equipment interface. New editions of the documents shall be backwards compatible with the older editions. There are also sub-documents which are identified by a SAE J3105/1, SAE J3105/2, and SAE J3105/3. These will be specific requirements for a specific interface defined in the sub-document.

2024-04-15
CURRENT
J1241_202404
This SAE Recommended Practice is applicable to two- or three-wheel motorcycles intended for highway use. Unless noted, requirements apply to both metallic and nonmetallic tanks. Accessory or aftermarket tanks as well as original equipment tanks are covered.

High Flow Liquid Hydrogen Fueling Couplings for Aerospace and Heavy Transport Applications
2024-04-15
WIP
AIR8999
The SAE AE-5CH Taskgroup has determined that high flow liquid hydrogen fueling couplings need to be developed in order to fast fill aircraft at the airport. Though the flow rates from a current liquid hydrogen bayonet connect may reach the lower bound flow rates of regional aircraft, there are some shortcomings to this connector for aerospace. For this reason a new specification for flow rates for regional to narrowbody (and potentially later widebody) are to be developed in this documenet. Harmonization for lower flow rates (such as up to 20kg/minute) are planned to be harmonized with ground vehicle fueling such as with ISO 13984. Within this document,coupling descriptions including Flow rates from 84 to 200 kg/minute will be evaluated (and potentially higher), and requirements and testing and safety targets will be specified.
