part numbering system

part numbering system

(OP)
We are in prefabricated building construciton business. My boss asks me to figure out a numbering system that will create a systematic way so our Client (US AIR FORCE) will be capable to read. I came up with something simple like a part number should correspond to:
company's name, product name, drawing number, component. Any of you have any standard how a part numbering system should be?

Thank you.

RE: part numbering system

I saw many "standards" used to number parts. One I liked alot is as following :

* Standard parts (screws, nuts, bolts etc) are referenced ####-####S

* Specific parts are referenced #####-#####

where first series of numbers is the assembly number and second series is the part reference

e.g.

Screw H M5-20 : 5203-0001S (part 1 of assy 5203 - standard part)
Aluminium Plate X x Y : 5203-0002  (part 2 of assy 5203)
etc

RE: part numbering system

From ASME Y14.100-2000 sec 6.2 "A nonsignificant numbering system is preferred."

I like systems that use unique numbers without tying them to any higher assemblies. This promotes reuse of designs to new projects.

Since you are contracting to the US Air Force, check into registering your company and getting a CAGE Code assigned.  That takes care of the company name issue.

There are entire standards on part numbering: DOD-STD-100, MIL-STD-100 which has been cancelled and replaced with ASME Y14.100.

I am most familiar with DOD-STD-100.  Chapter 400 deals with Numbers, Coding, and Identification.
The drawing number should consist of letters, numbers, or a combination of both and is only used for identification by the design activity (you).  The part number should consist of letters, numbers, or a combination of both and shall include the design activity drawing number and may or may not include a suffix.  Excluded letters are I, O, Q, S, X, Z to avoid font confusion with 0, 1, and 5.

Most of the time, the drawing number is a non-significant, sequential number--meaning it is not tied to any product or assembly.

I could go into more detail, but I think this is long enough to give you an idea and you can always get the standard yourself.

Rehi everyone,

Ya know more than my expectations. First, thank you Cyril for giving me several examples. Second, thank you Ben for filling me with a beautiful quote of the day and mention on the ASME Y14.100 when my boss just found out today and talked to me about the cancellation of Mil-Std-100. Third, thank you Scott for assisting right to the subject that I need, I mean everything Scott mention is exactly what I am looking for.

I really need to extend to the complexity of the p/n system. At the present time, we do not have an inventory system for the parts, basically every part that came out of the shop go to the Client (USAF), so every part should be identified to a drawing number, my problem is that there are some identical parts and if I dont have to include Drawing No. and I wont, but I really have to do that.
We are in the business of manufacturing hush houses (sound suppress) to test jet engines. So T-9, T-10, T-12 are having different structures. I am thinking about this breakdown structure for P/N system,

DFG-T9-E1-5WP2
CompanyName/ProductLine/Dwg No./component (whether component is a Kit, Enclosure or major component).

Additional Question is that do you know where I can get ASME Y14.100? I want to see the number system and also the Engineering Change Proposal Format to the Air Force.

Thank you
