EUROPEAN STANDARD (EN)
Used when the document is intended to meet needs specific to Europe and requires transposition into national standards, or when the drafting of the document is required under a standardization request from the European Commission (EC)/European Free Trade Association (EFTA). An EN is drafted by a Technical Committee within ETSI and approved by ETSI's European National Standards Organizations – for example ITS in Sweden.
Harmonised Standards are ENs with a special status. They are produced in response to an standardization request from the European Union. They provide the technical detail necessary to achieve the ‘essential requirements’ of an EU Directive. They are thus key enablers of the European Single Market. ETSI produced and continues to produce numerous Harmonised Standards for the Radio Equipment (RED) Directive.
ETSI GUIDE (EG)
Used for guidance to ETSI in general on the handling of specific technical standardization activities. It is submitted to the whole ETSI membership for approval.
ETSI TECHNICAL SPECIFICATION (TS)
Used when the document contains technical requirements and it is important that it is available for use quickly. A TS is approved by the Technical Committee that drafted it.
ETSI TECHNICAL REPORT (TR)
Used when the document contains explanatory material. A TR is approved by the Technical Committee that drafted it.
