Screw Threads - UNJ Profile, Inch, Controlled Radius Root with Increased Minor Diameter

2024-05-20
WIP
AS8879E
This project is part of the 5-year cycle review, minor clarification is proposed for the Material limits for coated or plated threads. Also, a short reference to 3BG threads is reinstated (pointing to MIL-S-8879 Rev A) for reference on legacy designs and end user awareness. Finally minor editorial updates are suggested, and tables are digitalized to improve searchability.

Devices for Use in Defining and Measuring Vehicle Seating Accommodation

2024-05-20
WIP
J826
The devices of this SAE Standard provide the means by which passenger compartment dimensions can be obtained using a deflected seat rather than a free seat contour as a reference for defining seating space. All definitions and dimensions used in conjunction with this document are described in SAE J1100. These devices are intended only to apply to the driver side or center occupant seating spaces and are not to be construed as instruments which measure or indicate occupant capabilities or comfort. This document covers only one H-point machine installed on a seat during each test. Certified H point templates and machines can be purchased from:SAE International400 Commonwealth DriveWarrendale, PA 15096-0001Specific procedures are included in Appendix A for seat measurements in short- and long-coupled vehicles and in Appendix B for measurement of the driver seat cushion angle. Specifications and a calibration inspection procedure for the H point machine are given in Appendix C.

Vacuum Gauge Calibration

2024-05-17
CURRENT
ARP7446A
This SAE Aerospace Recommended Practice (ARP) addresses the general procedure for the best practices for minimizing uncertainty when calibrating thermal conductivity and cold cathode vacuum gauges, which includes the vacuum sensor(s) and accompanying electronics necessary for a pressure measurement to be made. It also includes the best practices for an in-process verification where limitations make it impossible to follow the best practices for minimizing uncertainty. Verifying the accuracy and operation of vacuum gauges is critical to ensure the maintenance of processes while under vacuum.

Aerospace Series - Notice of Change (NOC)

2024-05-17
CURRENT
AS9116A
The aviation, space, and defense industries rely on the development and manufacture of complex products comprised of multiple systems, subsystems, and components each designed by individual designers (design activities) at various levels within the supply chain. Each design or manufacturing activity controls various aspects of the configuration and specifications related to the product. When a change to design or process is requested or required, the change is typically required to be evaluated against the impacts to the entire system. Proposed changes to design data/information that the design activity identifies to be minor and have no effect on the product requirements or specifications, have the potential to be implemented and approved, where authorized to do so, but requires notification. Changes that affect customer mandated requirements or specifications shall be approved prior to implementation.
