Standardization

Standardization is the process of establishing a standard among competing entities in a market, where this will bring benefits without hurting competition. As an example, all of Europe now uses 230 volt 50 Hz AC mains grids and GSM cell phones, and (at least officially) measures lengths in metres.

Standards can be de facto, which means they are followed for convenience, or de jure, which means they are used because of (more or less) legally binding contracts and documents. Government agencies often have to follow standards issued by official standardization organizations. Following such standards can also be a prerequisite for doing business on certain markets, with certain companies, or within certain consortia.

A standard can be an open one or not.

Important standardization bodies are:

• ANSI - American National Standards Institute (United States of America)
• DIN - Deutsches Institut für Normung (Germany)
• ETSI - European Telecommunications Standards Institute
• IEC - International Electrotechnical Commission
• IEEE - Institute of Electric and Electronic Engineers
• IETF - Internet Engineering Task Force
• ISO - International Organization for Standardization
• ITU-R, ITU-T - The International Telecommunication Union (ITU-T was formerly known as CCITT)
• IUPAC - International Union of Pure and Applied Chemistry
• SI - Système International d'Unités (International System of Units)
• SIS - Standardiseringskommissionen i Sverige (Sweden)
• SCC[?] - Standards Council of Canada (Canada)
• NIST - National Institute for Standards and Technology (United States of America)
• W3C - World Wide Web Consortium
