Hello: I'm researching part-naming-convention specifications. Fortunately, I found the posting entitled Naming Convention from Cragyon from August 28, 2002.  It references MIL-T-31000 and MIL-C-100.  Looking for status on these specifications and how I could obtain them.  If they are canceled, could I obtain these for free and what succeeded them? Best regards, - Tony Tony C.

Ok, here is a condensed version of part/drawing naming conventions. Title Assignment When assigning a drawing title, clearly describe the item with the most applicable noun name and, if necessary, additional modifiers. First Part of Item Name The first part of the item name shall be the noun name. It shall not contain the method of manufacturing, such as casting, forging, machining, etc. Noun Name The Noun Name is a noun or a noun phrase that best establishes a basic concept of the item. It describes what the part is and the usage of the part, and not the material or method of fabrication. A compound noun or noun phrase is used only when a single noun is inadequate or ambiguous. Example Basic Name BRACKET PISTON SLIDE RULE SOLDERING IRON (Noun) (Noun) (Noun Phrase) (Noun Phrase) First Part Modifiers When the noun name represents an item to which types, grades, variety, etc., are applicable, the remainder of the first part of the title consists of one or two modifiers. A modifier may be a single word or qualifying phrase. The first modifier serves to narrow the concept established by the basic name. Succeeding modifiers must continue a narrowing concept by expressing a different type of characteristic. A word directly qualifying a modifier precedes the word it qualifies, thereby forming a modifying phrase. Example: BRACKET, PRESSURE TRANSMITTER The word “PRESSURE” qualifies the word “TRANSMITTER”, thus a qualifying phrase is formed. Also, the modifier is separated from the noun or noun phrase or subsequent modifier by a comma. Second Part of the Item Name The second part of the item name may contain the word casting, forging, etc., only when there is a machining drawing as well as a casting, forging, etc., drawing. Second Part Modifiers The second part of a title is separated from the first part by a dash (-) and consists of modifiers or modifying phrases as required. Modifiers indicating what an item is (its shape, structure or form) or what an item does (its function) are preferable to modifiers indicating the application (what it is used for) or location (where used) of the item. When two or more drawings in the same major assembly are similar and the parts detailed thereon perform the same general function, they are distinguished by additional modifiers indicating location, position, form, dimensions, etc. Examples BRACKET, PRESSURE TRANSMITTER - OUTSIDE, LOWER BRACKET, PRESSURE TRANSMITTER - OUTSIDE, UPPER TUBE ASSY, METAL - FILTER INLET, TURBOPUMP TUBE ASSY, METAL - FILTER DISCHARGE, TURBOPUMP ITEM NAME ADDITIONAL MODIFIERS (First Part) (Second Part) GUIDE, SHAFT, BUTTERFLY VALVE-.010 INCH OVERSIZE, LOWER Noun Name, Modifier, Modifying Phrase, Modifying Phase, Modifier  Title Breakdown The singular form of the noun or noun phrase shall be used as the basic name, except as follows: 1. Where the only form of the noun is plural. Example: TONGS, SCISSORS. Etc. 2. Multiple single items on the same drawing (Tabulated). Example: BOLTS, SHIMS, SPACERS, WASHERS, FUSES, CONNECTORS, etc. (In the parts list of the next assembly, use the singular form of the name). Noun Abbreviations When using the word, “ASSEMBLY”, “SUBASSEMBLY” or “INSTALLATION” in a basic name, it appears as the last word in the noun phrase (first part) and may be abbreviated, if space is a problem. Examples SWITCH INSTL OR SWITCH INSTALLATION POWER DIVIDER SUBASSY OR POWER DIVIDER SUBASSEMBLY Ambiguous Noun An ambiguous noun, or one which designates several classes of items, is not used alone as the basic name, but as part of the noun phrase. Examples Acceptable Not Acceptable TERMINAL BOARD WIRING HARNESS SHOCK ABSORBER BOARD, TERMINAL HARNESS, WIRING ABSORBER, SHOCK When the item is not a container or material, but its basic name involves the use of a noun which ordinarily designates a container or material, use a noun phrase as the basic name. Examples Acceptable Not Acceptable JUNCTION BOX BOX, JUNCTION SOLDERING IRON IRON, SOLDERING A trademarked or copyrighted name shall not be used as the noun name, except where the technical name is extremely difficult. Example “Refrigerant-12” rather than “DICHLORODIFLUORMETHNE” Drawing Types Included In Title The following types of drawings shall include the drawing type as the second part of the title: BLOCK DIAGRAM DRAWING TREE INTERCONNECTION DIAGRAM MANUFACTURING FLOW CHART SCHEMATIC DIAGRAM SYSTEM DIAGRAM WIRING DIAGRAM Drawing Types Not To Be Used In Title The following type drawings shall not be used as part of a title. They should be shown in .25 High Bold Characters Above the Title Block. INTERFACE CONTROL DRAWING SOURCE CONTROL DRAWING SPECIFICATION CONTROL DRAWING VENDOR ITEM DRAWING ENVELOPE DRAWING ALTERED ITEM DRAWING General Rules 1. Uppercase letters shall be used. 2. The conjunction “OR” and the preposition “FOR” are not to be used. 3. Hyphens in compound words are not considered as punctuation marks. Use hyphenated words when a Basic Name such as HEATER-GENERATOR UNIT applies to an item with combined functions. 4. Abbreviations are not used for any portion of the item name (first part of title) except for the words ASSEMBLY (ASSY), SUBASSEMBLY (SUBASSY) and INSTALLATION (INSTL). 5. Abbreviations may be used in the second part of the title. 6. Symbols shall not be used in any part of the title. 7. Abbreviations that permit more than one interpretation or make the title difficult to read shall not be used. In general, any use of abbreviations should be avoided. 8. Parenthetical words or phrases are not used in drawing titles. Examples: (CAST), (WELDMENT), (ASSEMBLY OF), (MACHINED), etc. 9. A drawing title shall be as brief and simple as possible, and shall describe the item and distinguish between similar items. 10. New Drawings: When one drawing replaces another, the title is the same providing the old title was prepared in accordance with the instructions contained in this Section. When the title of the drawing being replaced is not in accordance with these instructions, a new drawing title shall be developed and approved. 11. Program or customer names shall not be used in drawing titles except highest-level assembly documents. 12. The following words shall never be used alone but may be the last word of a noun phrase: APPARATUS MACHINE ASSEMBLY MECHANISM ASSORTMENT OUTFIT ATTACHMENT PLANT COMPOUND SHIP DEVICE SUBASSEMBLY ELEMENT TACKLE EQUIPMENT TOOL GROUP UNIT INSTALLATION VEHICLE KIT
