## ETSI
### Nomenklatur

(Die Regelungen zur Verabschiedung und Status von ETSI-Dokumenten werden in den sogenannten ETSI Directives festgehalten.)
Die Dokumente der ETSI werden unterschieden in

#### Derzeit gültige Nomenklatur

* EN European Standard Ein EN ist ein Dokument, das von ETSI gemäß dem Membership Voting-Verfahren verabschiedet wurde und normative Regelungen enthält. Zusätzlich muss dieses Dokument vom Europäischen Komitee für Normung (CEN) als Europäische Norm angenommen werden. Europäische Normen werden von den Mitgliedsstaaten des CEN als nationale Norm übernommen.
* ES ETSI Standard Ein ES ist ein Dokument, das von ETSI gemäß dem Membership Voting-Verfahren zur Veröffentlichung verabschiedet wurde und normative Regelungen enthält.
* EG ETSI Guide Ein EG ist ein Dokument, das von ETSI gemäß dem Membership Voting-Verfahren zur Veröffentlichung verabschiedet wurde und hauptsächlich informative Regelungen enthält, die für die gesamten ETSI-Mitglieder von Bedeutung sind.
* TS Technical Specification Ein TS ist ein Dokument, das von einem ETSI Technical Body zur Veröffentlichung verabschiedet wurde und normative Regelungen enthält.
* TR Technical Report Ein TR ist ein Dokument, das von einem ETSI Technical Body zur Veröffentlichung verabschiedet wurde und hauptsächlich informative Regelungen enthält.
* SR Special Report Ein SR ist ein Dokument, das Informationen enthält, die zu Referenzierungszwecken veröffentlicht werden.
* Harmonized Standard Ein Harmonized Standard ist ein EN, der von ETSI im Rahmen eines Mandats der Europäischen Kommission unter der Europäischen Richtlinie 98/48/EG erstellt wurde.

#### Vorherige Nomenklatur

* Amendment Ein Amendment ist ein Dokument, das eine inhaltliche Änderung eines ETS, I-ETS, ETR oder TBR enthält. Ein Amendment wird von einem ETSI Technical Body und nachfolgend entsprechend dem Abstimmungsverfahren des jeweiligen Dokumententyps verabschiedet.
* Corrigendum Ein Corrigendum ist ein Dokument, das editorielle Änderung eines ETS, I-ETS, ETR oder TBR enthält. Ein Corrigendum wird vom ETSI-Sekretariat oder vom Vorsitzenden eines Technical Body veröffentlicht.
* ETS European Telecommunication Standard Ein ETS entspricht einem EN nach der derzeit gültigen Nomenklatur.
* I-ETS Interim European Telecommunication Standard Ein I-ETS ist ein Dokument, das von ETSI gemäß dem gewichteten nationalen Abstimmungsverfahren zur Veröffentlichung verabschiedet wurde und normative Regelungen enthält.
* ETR ETSI Technical Report Ein ETR ist ein Dokument, das von einem ETSI Technical Committee (jetztTechnical Body) zur Veröffentlichung verabschiedet wurde und hauptsächlich informative Regelungen enthält. Ein ETR entspricht einem TR nach der derzeit gültigen Nomenklatur.
* GSM-TS GSM Technical Specification Ein GSM-TS ist ein Dokument, das von der Special Mobile Group (frz. Groupe Spéciale Mobile) zur Veröffentlichung verabschiedet wurde.
* TBR Technical Basis for Regulation Ein TBR ist ein Dokument, das von ETSI im Rahmen eines Mandats der Europäischen Kommission speziell zu Zwecken der Europäischen Regulierung erstellt wurde und nur Anforderungen gemäß der Europäischen Richtlinie 98/13/EG enthält.
Es kann zum gleichen Thema verschiedene Dokumententypen geben. Bei der Dokumentennummer ist dann jedoch der Ziffernbereich gleich. Deshalb werden bei der Liste der ETSI-Dokumente die Dokumententypen nicht berücksichtigt (Ausnahme sind hier die TS-, TR- und SR-Dokumente). Viele Dokumente bestehen aus mehreren Schriftstücken, die dann durch Anhängen von Ziffern unterschieden werden (zum Beispiel ETS 300 011-1 bis ETS 300 011-3); auch diese Unterscheidung wird in der Liste nicht berücksichtigt.
