Harmonized standards specify the technical details regarding the diverse radio equipment along with possible test methods to demonstrate compliance with relevant requirements of the EU legislation. At the request of the European Commission, they are developed by the European standardization organizations (ESO): the European Telecommunications Institute (ETSI), the European Committee for Standardization (CEN) and the European Committee for Electrotechnical Standardization (CENELEC). The fully independent ESOs are private bodies that comprise industry experts, government bodies and other stakeholders.
