MIL-STD-275E, MILITARY STANDARD: PRINTED WIRING FOR ELECTRONIC EQUIPMENT (31 DEC 1984) [SUPERSEDES MIL-STD-1495] [S/S BY IPC-2221 OR IPC-D-275]., This standard establishes design requirements governing rigid, single printed-wiring boards, double-sided printed -wiring boards, multi-layered printed-wiring boards, printed-wiring assemblies constructed from those boards mentioned above, and design considerations for mounting of parts and assemblies thereon. The design criteria (such as electrical spacings) contained in this standard are predicated on the requirement that end item assemblies [circuit card assemblies, printed-wiring assemblies, back planes, mother boards) shall be conformally coated (see 6.3.1). Conformal coating shall be in accordance with MIL-I-45059.

Title:Automotive Malleable Iron Castings (Cancelled Apr 2003)
Issuing Committee:Automotive Iron And Steel Castings Committee
Scope:This standard covers the hardness and microstructural requirements for malleable iron castings - ferritic, pearlitic, tempered pearlitic, and tempered martensitic grades used in automotive and allied industries. Castings shall be heat treated to meet this SAE Standard. The Appendix provides general information on the application of malleable iron castings and their chemical composition to meet hardness, microstructure, and other properties needed for particular service conditions. The mechanical properties in the Appendix are provided for design purposes.The specific grades, hardness range, and final heat treatment are shown in Table 1.
