Specification
From Free net encyclopedia
In engineering and manufacturing, the term specification has the following meanings:
Technical requirement
A specification is a set of requirements. See also requirements analysis. Normally, a specification is the specific set of (high level) requirements agreed to by the sponsor/user and the manufacturer/producer of a system. The specification may also contain both the systems requirements and the test requirements by which it is determined that the systems requirements have been met, known as the acceptance test requirement(s), and a mapping between them.
Procurement
An official document intended primarily for supporting procurement, which document clearly and accurately describes the essential technical requirements for items, materials, or services, including the procedures by which it will be determined that the requirements have been met.
An example of a Federal specification is FIPS-PUB 159, Detail Specification for 62.5-μm Core Diameter/125-μm Cladding Diameter Class Ia Multimode Optical Fibers.
