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

I couldnt find those Military Specs but if you ever want to look up similar ones here is the site:

http://assist.daps.dla.mil/online/start/

do a quick search (its on lthe left)

Fill in the Mil spec number you want in the document ID and the records will come up. when you find them there will be a stack of papers icon and click that. it will gve you the revisions and downloadable pdfs if available. Also everything is FREE! Good luck.

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
