Source of Control Reference. The number assigned by a design control manufacturer of an end item of equipment, including a Government activity, to a drawing that restricts procurement (1) to the specified item(s) described on the drawing and (2) to the stated source(s) of supply designated thereon. These restrictions are imposed on the cognizant design activity to ensure procurement of the only item(s) known as a result of test or evaluation to be satisfactory for the stated critical application. Includes only those drawings which meet the definition for Source Control Drawing in MIL-STD-100. (Applicable only to type 1, 1B, 2, 4 and 4B item identifications.)
Design Control Reference. The primary number used to identify an item of production or a range of items of production, by the manufacturer (individual, company, firm, corporation, or Government activity) which controls the design, characteristics, and production of the item by means of its engineering drawings, specifications and inspection requirements.
Secondary Reference. Any additional number, other than a primary number (codes 1,2,3,4) informative reference (code 6) or vendor item drawing reference (code 7) assigned to an item of production or supply by a commercial or Government organization, which represents the same item of production or supply to which the National Stock Number (NSN) was assigned. The reference number may have had an RNCC of 1, 2, 3, 4 or 7 but has since been replaced in the item-of-supply concept of the NSN by another primary number.
Replaced Reference Number. A manufacturerÆs part number, government specification/standard or other design control reference number that is superseded, discontinued or replaced resulting from a cancel-use action on a NSN which was recorded with ISC 3 or E. This reference number is automatically moved and this code is automatically assigned, do not submit for cataloging purposes.
A design control or other reference number that is an item-identifying number for an item of production, or a source control reference or a specification or standard part, type, or similar reference number that is an item-identifying number for an item of supply.
A specification, standard, or other reference number which is superseded, canceled, obsolete or discontinued and is coded Reference Number Category Code (RNCC) 5; a reference number for information only coded RNCC 6; or a reference number coded RNCC D.
A non-item-identifying reference number that is added to a replacement NSN as a result of a cancel-use action on a NSN recorded with ISC 3 or E. It is used to indentify the original item of supply/replaced item. This reference number is automatically moved and this code is automatically assigned, do not submit for cataloging purposes.
