MIL-HDBK-115B(ARMY) APPENDIX C
c. A group of assemblies required to form an assembly of higher order.
NOTE: An assembly drawing contains sufficient views to show the relationship between each subordinate assembly and part comprising the assembly depicted.
C.4.1.2.3 Detailed assembly drawing. This drawing depicts an assembly on which one or more parts are detailed in the assembly view or on detail views.
C.4.1.2.4 Matched parts drawing. This drawing depicts parts that are machine- matched or otherwise mated, and for which replacement as a matched set or pair is essential.
C.4.2. Schematic or electrical diagrams. These diagrams show, by means of graphic symbols, the electrical connections and functions of a specific circuit arrangement. They facilitate tracing the circuit and its functions without regard to the actual physical size, shape, or location of the component devices or parts.
C.4.3 Control drawing. This is an engineering drawing that discloses configuration and configuration limitations, performance and test requirements, weight and space limitations, access clearance, pipe and cable attachments, etc. The required level of detail is that necessary to allow the development or procurement of an item on the commercial market, or the installation and co-functioning of an item with related items. Control drawings are identified in four categories: Specification Control, Source Control, Altered Item, and Selected Item Drawings, as follows:
C.4.3.1 Specification control drawing.
a. A specification control drawing depicts an existing commercial item or vendor developed item which is advertised or cataloged as available on an unrestricted basis, on order as an off-the-shelf item, or as an item which, while not commercially available, is procurable on order from a specialized segment of an industry. The drawing, under the heading "Suggested Source(s) of Supply," lists the name (address if known), manufacturer's CAGE number, and item identification number of two or more known sources unless, after search of vendor data for similar products, it is determined that there is only one source. In addition, the notation "Specification Control Drawing" appears above the title block. The manufacturer's (vender's) part number is the item identification. The following appears in the body of the drawing:
"IDENTIFICATION OF THE 'SUGGESTED SOURCE(S) OF SUPPLY' HERON IS NOT BE CONSTRUED AS A GUARANTEE OF PRESENT OR
CONTINUED AVAILABILITY AS A SOURCE OF SUPPLY FOR THE ITEM(S)."
b. A specification control drawing discloses, as applicable, configuration, envelop dimensions, mounting and mating dimensions, interface dimensional characteristics, and limits to these dimensions. As necessary, it also discloses inspection and acceptance test
