Part. One piece, or two or more pieces joined together, which are not normally subject to
disassembly without destruction or impairment of designed use. (Examples: transistor,
composition resistor, screw, gear, transformer, milling cutter).
Part or Identifying Number (PIN). The identifier assigned by the responsible design
activity or by the controlling nationally recognized standard which uniquely identifies (relative to
that design activity) a specific item. The PIN generally includes the controlling drawing or
document number and optional suffix. The PIN does not include the drawing revision identifier,
drawing size, or CAGE Code. The term "part or identifying number" replaces the terms "part
number" and "bulk material identification number". (ASME Y14.24M and MIL-STD-961)
Procuring activity. A component of a Government agency having a significant acquisition
function and designated as such by the head of the agency. Unless agency regulations specify
otherwise, the term “procuring activity" shall be synonymous with “contracting activity."
Product. Includes materials, parts, components, subassemblies, assemblies, and
equipments. The term product wherever used in this document shall also encompass a family of
products. A family of products is defined as all products of the same classification, design,
construction, material, type, etc., produced with the same production facilities, processes, and
quality of material, under the same management and quality controls, but having the acceptable
variety of physical and functional characteristics defined and specified in the applicable
engineering documentation.
Product definition data. Denotes the totality of data elements required to completely
define a product. Product definition data includes geometry, topology, relationships, tolerances,
attributes and features necessary to completely define a component part or an assembly of parts
for the purpose of design, analysis, manufacture, test and inspection. (MIL-PRF-28000).
Production master. A 1 to 1 scale pattern which is used to produce one or more printed
boards (rigid or flexible) within the accuracy specified on the Master Drawing. (ANSI/IPC-T-50).
