19、duct identification system in all types of business communications media (verbal, written, bar code and Electronic Data Interchange EDI). The product identification system presented in this document is based on the UPC system. The UPC system provides for an eleven digit character string. The string
20、consists of a six digit manufacturers number assigned by the Uniform Code Council plus a five digit item identifier assigned by the manufacturer. These eleven digits uniquely identify a manufacturers product. Depending on the specific bar code system to be used, this number may be preceded by additi
21、onal characters or followed by a check digit. With the growing use of the UPC numbering system in the industry and the desire for item identification, it became apparent that in order to serve the needs of customers of the electrical industry, some type of standardization of the five digit item iden
22、tification numbers for conduit products was desirable. The numbering scheme set forth in this publication was established by the Steel Rigid Conduit and EMT Section of NEMA and is intended to fulfill the need for unique identification of the manufacturer as well as the need for uniform item identifi
23、cation. In the preparation of this Standards Publication, input of users and other interested parties has been sought and evaluated. Inquiries, comments, and proposed or recommended revisions should be submitted to the concerned NEMA product subdivision by contacting the: Vice President, Engineering

35、identify each of the manufacturers products. The combination of these elements into one eleven-digit number-the UPC number-identifies one, and only one item. As indicated above, the first six digits in the UPC code are the manufacturer identification number. Upon application and payment of the appro
36、priate fee, the Uniform Code Council, Inc. (UCC) will assign a manufacturer identification number. The assignment of a manufacturer identification number by one agency (UCC) prevents the issuance of the same number to two different manufacturers or two different numbers to the same manufacturer (exc
37、ept in specific situations defined in the UCC guidelines). Manufacturer ABC 023451 Manufacturer XYZ 054321 To uniquely identify 10 - I EMT from 12345. 10 - “ EMT 12345 10 - I EMT 12345 The second part of the WC code identifies each product a manufacturer produces. This is a five digit number which m
38、ay be selected and maintained by the manufacturer. The UPC industrial Code Guidelines Manual outlines concepts and guidelines for use in assigning item numbers in an orderly and efficient manner. The five-digit number uniquely identifies each product a manufacturer produces and will accommodate 100,
39、000 items (OOOOO - 99999). Authorized Engineering Information 3-4-1 991. 3.2 Commodity Identification Through the Use of Standardized Item Identifiers The use of the complete eleven-igit UPC Code permits the unique identification of products. With the use of the standard industry five-digit item num
40、bers presented in this publication, a means is provided to those in the industry for uniform coding and identification of like conduit products. For example: Check Digit* 6 Check Digit O specific manufacturer one would specify 023451-12345 or 054321- - % When this number is used with a bar code symb
41、ology a twelfth character (check digit) is used.

45、hers, this listing has been made as complete as possible and is intended to provide identification numbers for tubular metallic conduit products made on a repetitive basis. - - However, due to oversight during the development of this publication, or new product introductions, the listing of product
46、identification numbers appearing in this publication may be incomplete. Therefore, provision has been made to permit the inclusion of additional item numbers. A company desiring a new item number because of an omission or introduction of a new product should contact the NEMA Staff Executive for the
47、Steel Rigid Conduit and EMT Section, who will maintain the list of numbers and their respective product descriptions. It is emphasized that the product identification numbers listed in this publication are intended to include only like proucts produced by multiple manufacturers. They are intended to
48、 serve a need by the industry where such products are manufactured on a repetitive basis. Proprietary products, special ordered products, etc., may not be appropriate for inclusion. Also, it should be emphasized that this is strictly a voluntary e system and a manufacturer may utilize any number of
49、their choice to identify standard or non-standard products. However, if listing in the system covered by this document is requested, the Staff Executive will propose unused numbers from a reserved block of numbers which the requestor will be free to use as they deem appropriate. A unique product identification number will be required for each identifiable saleable unit, whether it is a package of 1, 3, 5, 10, etc. Numbers in the system covered in the document are intended to be assigned to package quantities that have gained common usage in t
