Different types of ETSI standards

ETSI produces a range of specifications, standards, reports and guides, each with its own particular purpose. Collectively they are all called standards or ‘deliverables’.

The ability to produce these different types of documents allows us to meet the variety of needs within the different industries we serve.

Each type of standard also requires a different process of approval.

  • 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 mandate from the European Commission (EC)/European Free Trade Association (EFTA). An EN is drafted by a Technical Committee and approved by European National Standards Organizations.
  • ETSI Standard (ES) – Used when the document contains technical requirements. An ES is submitted to the whole ETSI membership for approval.
  • 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.
  • ETSI Special Report (SR) – Used for various purposes, including to make information publicly available for reference. An SR is approved by the Technical Committee which produced it.
  • ETSI Group Report (GR) - An ETSI deliverable, containing only informative elements, approved for publication by an Industry Specification Group.
  • ETSI Group Specification (GS) – Provides technical requirements or explanatory material or both. Produced and approved within our Industry Specification Groups (ISGs).

Harmonised Standards

Harmonised Standards are ENs with a special status. We produce them in response to an EC mandate. They provide the technical detail necessary to achieve the ‘essential requirements’ of an EC Directive. They are thus key enablers of the European Single Market.

We produced and continue to produce numerous Harmonised Standards for the Radio Equipment (RED) Directive.

Community Specifications

We also produce ENs under the Single European Sky Interoperability Regulation (i.e. in civil aviation). These ENs are also produced in response to EC Mandates, in co-operation with EUROCAE (the European Organization for Civil Aviation Equipment). They acquire the status of Community Specifications (CSs) when they are published in the Official Journal of the European Union.
