ASME Y14-24 pdf free download Types and Applications of Engineering Drawings Engineering Drawing and Related Documentation Practices
3.17 Drawing drawing: an engineering document or data set that dis- closes, directly or by reference, by means of graphic or textual presentations, or by combinations of both, the physical or functional requirements of an item. (ASME Y14.100)
3.18 Drawing Tree drawing tree: a block diagram or indentured list that identifies all drawings applicable to an end item or pro- gram and illustrates the next higher and subordinate relationships that exist between those drawings.
3.19 End Product (End Item) end product (end item): an item, such as an individual part or assembly, in its final or completed state. 3.20 Inseparable Assembly inseparable assembly: same as part. (ASME Y14.100)
3.21 Interchangeable Item interchangeable item: an item that possesses functional and physical characteristics equivalent in performance to another item of similar or identical purposes, and is capable of being exchanged for the other item without selection for fit or performance, and without alteration of the items themselves or of adjoining items, except for adjustment. (ASME Y14.100)
3.22 Item item: a nonspecific term used to denote any unit or prod- uct, including materials, parts, assemblies, equipment, accessories, and computer software. (ASME Y14.100)
3.23 Item Identification item identification: the Part or Identifying Number (PIN) for a specific item along with the original Design Activ- ity Identification (DAI). (ASME Y14.100)
3.24 Multiprogrammable Memory Device multiprogrammable memory device: a memory device con- taining software instructions or data thatcanbe changed in the device once programmed [e.g., Electrically Alterable Read-Only Memory (EAROM)].
3.25 Nationally Recognized Standard nationally recognized standard: a specification or standard developed by or for a government activity or by a non- governmental organization issued with the intent to establish common technical requirements.
3.26 Nongovernmental Organization nongovernmental organization: a private sector associa- tion, organization, ortechnicalsocietythatconducts pro- fessional standardization activities (e.g., the planning, developing, establishing, and public coordination of 5 standards, specifications, handbooks, or related docu- ments) and is not organized for profit.
3.27 One-Time Programmable Memory Device one-time programmable memory device: a memory device containing software instructions or data that cannot be changed in the device once programmed [e.g., Programmable Read-Only Memory (PROM), Programmable Array Logic (PAL)].
3.28 Part part: one item or two or more items joined together that are not normally subject to disassembly without destruction or impairment of designed use (e.g., transis- tor, composition resistor, screw, transformer, and gear). (ASME Y14.100) 3.29 Part or Identifying Number (PIN) Part or Identifying Number (PIN): the identifier assigned by the original design activity or by the controlling nationally recognized standard that uniquely identifies, relative to that design activity, a specific item. (ASME Y14.100) 3.30 Performance Specification performance specification: a specification that states requirements in terms of the required results with crite- ria for verifying compliance, but without stating the methods for achieving the required results. A perform- ance specification defines the functional requirements for the item, the environment in which the item operates and interfaces, and the interchangeability characteristics. 3.31 Printed Board printed board: the general term for completely processed printed circuit and printed wiring configurations. This includes single-sided, double-sided, and multilayer boards with rigid, flexible, and rigid-flex base materials.
3.32 Printed Circuit printed circuit: a conductive pattern composed ofprinted components, printed wiring, or a combination thereof that is formed in a predetermined arrangement on a common base.
3.33 Printed Component printed component: a part, such as an inductor, resistor, capacitor, or transmission line, that is formed as part of the conductive pattern of a printed board.
