MIL-HDBK-115B(ARMY)
5.26.2.3 Heat treatment. The capability of materials to respond to specified heat treatments should be verified and specified. SAE-AMS2770, SAE-AMS2771, SAE-AMS2772, and SAE-AMS-H-6875 may be used as guides.
5.26.2.4 Finishes. The impact of finishes on function and cost should be evaluated. The most economical finishes that will satisfy the functional requirements should be specified. If machine finishes are required, the highest roughness acceptable should be specified for the designed function.
5.26.2.5 Clean and joining methods. The proper joining methods, such as mechanical fasteners, metallurgical welding, brazing, soldering, and chemical adhesives, should be specified and evaluated for applicability, ease of access during the joining process, and alternate method of joining for cost reduction. The following documents may be used as guidance:
a. Welding: MIL-STD-22
ANSI/AWS A2.4
ANSI/AWS A3.0
b. Brazing: AWS C3.4
AWS C3.5
AWS C3.6
AWS C3.7
5.26.2.6 Coatings. The proper coatings, surface treatments and finishes should be specified, including proper paint specifications and pre-treatments. MIL-STD-171 may be used as guidance.
5.26.2.7 Selection of standard parts/components. The parts defined by military standard (MS), Army-Navy (AN), National Aircraft Standards (NAS), or other Government standards, should be used wherever possible for compliance with the requirements of the applicable standards.
5.26.2.8 Quality assurance provisions. Where applicable, the drawings should list the appropriate data concerning acceptance of detail parts or assemblies, as follows:
a. Dynamic tests, defining pertinent cycling, torsional deflection capabilities, and gear backlash,
b. Electrical parameters and characteristics, continuity checks, dielectric data, and durability,
