Standards may be one of the following types:
Private standards are for use only by the organization that developed them
Publicly available standards can be, for example, a standard produced by a trade association that may be
used by any organization
British Standards are produced by BSI
British Standards and developed in collaboration with UK government, businesses and society. Some are enforced by regulation, but for most compliance is voluntary
European Standards are produced by CEN, the
European Committee for Standardization, whose members are the national
standards bodies of European Union countries. All European Standards are
adopted as British Standards
International Standards are produced by ISO, the
International Organization for Standardization, whose members are the national standards bodies of countries all over the world. The UK decides whether to adopt international standards as British Standards
Standards can apply to products, processes or services. A well known 'process' standard is the ISO 9000 series, which provides a framework for the effective management of organizations.
Formal standards, such as British, European or international standards, vary in the strength of their provisions; for example, they may specify requirements for the features or characteristics of a product, or simply recommend the best way of doing something.
Evaluation bodies provide testing, certification, inspection or calibration services for organizations wanting their product or service to comply with international, European or British Standards.
