AMS2435H
This specification covers the engineering requirements for applying tungsten carbide/cobalt coatings to metal parts by the detonation process and the properties of such coatings. This coating has been used typically to provide a hard, wear resistant surface on metal parts which do not operate in service higher than 1000 degrees F (538 degrees C) but usage is not limited to such applications. These coatings are not recommended for surfaces with deep vee-shaped grooves, blind cavities, narrow holes or sharp corners, or where deformation of the base metal may be expected. Higher cobalt content provides increased ductility for applications where impact or fretting wear is involved.

AMS2550F
This specification covers the enginering requirements for a treatment to provide enhanced corrosion resistance to sheet metal parts, such as brackets, spacers, and washers, fabricated from martensitic corrosion-resistant steels, usually AMS 5504 or AMS 5508 and having hardness not higher than 40 HRC, or ferritic corrosion-resistant steels, usually AMS 5506. The treatment is not recommended for use on parts subject to impact in service.

AMS2628B
This specification covers procedures for ultrasonic immersion inspection of premium grade wrought titanium and titanium alloy round billet 5.0 inches (127 mm) and over in nominal diameter. This inspection procedure has been used typically for locating internal defects such as cracks, voids, inclusions, and other structural discontinuities which may or may not be exposed to the surface in billets, but usage is not limited to such applications. Testing normally will be by longitudinal procedure, but shear wave procedure may be added when agreed upon by purchaser and vendor. This specification includes zoned inspection and digital data acquisition.

ARP4252B
This Aerospace Recommended Practice is intended as a guide toward standard practices for the determination of surface cleanliness that are applicable to field operation. Some of these methods can also be used to determine quality assurance that a surface has been properly prepared and maintained. The instrumental methods are: Wettabaility, Surface Potential Difference (SPD), Ellipsometry, and Optically Stimulated Electron Emission (OSEE). Each instrument is described with respect to measurement techniques, limitations, and advantages and types of available instruments. Elementary theoretical prinicples and examples of the use of each instrument are also given.

This document defines a set of standard application layer interfaces called JAUS Mission Spooling Services. JAUS Services provide the means for software entities in an unmanned system or system of unmanned systems to communicate and coordinate their activities. The Mission Spooling Services represent the platform-independent capabilities commonly found across all domains and types of unmanned systems. At present, 1 service is defined in this document (more services are planned for future versions of this document): • Mission Spooler: Stores mission plans, coordinates mission plans, and parcels out elements of the mission plan for execution The Mission Spooler service is described by a JAUS Service Definition (JSD) which specifies the message set and protocol required for compliance. The JSD is fully compliant with the JAUS Service Interface Definition Language [JSIDL].

AS6960
Seat surrounding furniture (commonly known as shells) is intended to enhance passenger comfort and privacy. They can offer additional space for reclining the seat into a bed position, additional stowage, amenities, etc. Often some amenities are located on the furniture including the front row monument installed in front of the passenger seat. The units normally attach to the same aircraft floor tracks directly in front or behind passenger seat(s) or to the seat primary structure. The unit structures are not directly integrated into the main fuselage and do not offer main supports for aircraft integrity. This Aerospace Standard (AS) establishes the minimum design, performance and qualification requirements for Seat Surrounding Furniture to be certified for installation in transport category airplanes.
