Specification (technical standard)
A specification (often abbreviated as spec) is a type of technical standard that acts as an explicit set of requirements to be satisfied by a material, product, or service. Should a material, product or service fail to meet one or more of the applicable specifications, it may be referred to as being "out of specification" (OOS).
