Drawing Identification

In recognition of the fact that drawing numbers are assigned and controlled by a design activity and not by some national or industry wide issuing authority, a drawing number in itself does not establish a unique identity, or drawing identification, for the drawing. Drawing identification is established through the association of a drawing number and a design activity identification. 6.5.1 CAGE Code. CAGE Code is used by the Government and many industrial activities for drawing, item, and...

The addition of the note constitutes a change therefore, an applicable entry in the revision history block in...

Identification Cross Reference

When items are identified by more than fifteen characters or do not meet the other requirements of paras. D9.5 and D9.6 and a design activity has no control over this assignment, an administrative control number may be assigned to the item in order to meet the identification requirements of paras. D9.5 and D9.6. This includes items controlled by Government and nonGovernment standardization documents. The administrative control number shall identify the item for administrative purposes.

Changes Not Requiring New Identification

When a part or assembly is changed in such a manner that conditions of section D13 do not occur, the PIN shall not be changed. Under no condition shall the PIN be changed only because a new application is found for an existing part.
