A technical standard may be developed privately or unilaterally, for example by a corporation, regulatory body, military, etc. Standards can also be developed by groups such as trade unions, and trade associations. Standards organizations often have more diverse input and usually develop voluntary standards: these might become mandatory if adopted by a government, business contract, etc.
The standardization process may be by edict or may involve the formal consensus of technical experts.
The primary types of technical standards are:
– A standard specification is an explicit set of requirements for an item, material, component, system or service. It is often used to formalize the technical aspects of a procurement agreement or contract. For example, there may be a sp ecification for a turbine blade for a jet engine that defines the exact material and performance requirements.
– A standard test method describes a definitive procedure that produces a t est result. It may involve making a car eful personal observation or conducting a highly technical measurement. For example, a physical property of a material is often affected by the precise method of testing: any reference to the property should therefore reference the test method used.
– A standard practice or procedure gives a set of instructions for performing operations or functions. For example, there are detailed standard operating procedures for operation of a nuclear power plant.
– A standard guide is general information or options that do not require a specific course of action.
– A standard definition is formally established terminology.
– Standard units, in physics and applied mathematics, are commonly accepted measurements of physical quantities.
