The U.S. Department of Defense Standard Practice for System Safety (MIL–STD–882) places the highest priority on elimination of hazards through design selection. [21] One of the most common fail-safe systems is the overflow tube in baths and kitchen sinks.
MIL-STD-1750, an instruction set architecture (ISA) for airborne computers [30] MIL-STD-1760, smart-weapons interface derived from MIL-STD-1553 [31] MIL-STD-1815, "Ada programming language" [32] MIL-STD-1913, Picatinny rail, a mounting bracket on firearms; MIL-STD-2045, Connectionless Data Transfer Application Layer
For military aerospace and defense systems MIL-STD-882E addresses functional hazard analyses (FHA) and determining which functions implemented in hardware and software are safety significant. The Functional safety focus is on ensuring safety critical functions and functional threads in the system, subsystem and software are analyzed and ...

Note that AN threads are different for bolts and fittings. In bolts the number refers to the diameter of the bolt whereas in a fitting it refers to the OD of the tube and thereby have different threads. For example, AN6 bolt has a 3 ⁄ 8-24 thread [3] whereas an -6 AN fitting has a 9 ⁄ 16-18 thread. [4]
The standard designation for a UTS thread is a number indicating the nominal (major) diameter of the thread, followed by the pitch measured in threads per inch.For diameters smaller than 1 / 4 inch, the diameter is indicated by an integer number defined in the standard; for all other diameters, the inch figure is given.
