On a European level, there are three formal standards organizations: CEN, CENELEC and ETSI. These are recognized by the EU and meet the WTO criteria for standards setting. All three have cooperation arrangements in place with their global counterparts: ISO , IEC and ITU . In addition, there are several formal standards bodies working on a national level, which also have wider impact, such as DIN (Deutsches Institut für Normung), ANSI (American National Standards Institiute) or BSI (British Standards Institution).
