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.

CURRENT
AMS2431/7C
The complete requirements for procuring the product shall consist of this document and the latest issue of the basic specification, AMS2431.
Standard

Inspection of Ground, Chromium Plated Steel Parts
2019-07-18
CURRENT
AMS2440C
This specification covers the requirements for inspection of ground chromium plated surfaces for grinder-induced damage to the chromium plate and substructure. The specification also provides users with criteria for distinguishing between such damage and acceptable indications inherent to the chromium plate.
Standard

Gaseous Nitrocarburizing
2019-03-15
CURRENT
AMS2757C
This specification covers the engineering requirements for producing a continuous thin epsilon-iron-carbonitride compound layer on parts by means of a gaseous, low temperature process, and properties of the case.

Automated Gaseous Nitrocarburizing Controlled by Potentials
2018-07-02
CURRENT
AMS2759/12B
This specification covers the requirements for producing a continuous white layer with controlled extent of porosity by means of a gaseous process, automatically controlled to maintain set values of the nitriding and carburizing potentials that determine properties of the nitrocarburized surface. Automatic control is intended to ensure repeatability of nitrogen and carbon content of the white layer which influences properties such as wear and corrosion resistance, ductility and fatigue strength.

CURRENT
AMS2759/13
This specification covers the engineering requirements for producing a continuous thin epsilon-iron-carbonitride compound layer on parts by means of a gaseous, low temperature carbon enriched nitriding process. The process is intended to utilize an atmosphere of high nitriding potential that produces a compound layer. If the compound layer is intended to be controlled automatically, AMS2759/12 shall be used.
Standard

Phosphate Treatment of Iron and Steel
2017-10-04
CURRENT
AMS03_11A
This SAE Standard specifies requirements for the processing of iron and steel (excluding corrosion resisting steels) to produce coatings consisting essentially of inorganic phosphates, which are intended to be used in conjunction with supplementary finishes for the protection of the basis metal against corrosion (and in certain cases to give, additionally, anti-wear properties to sliding surfaces).
