Work in ETSI is done on the basis of ETSI work items, approved by the Technical Body and adopted by the ETSI membership.
A work item results in one deliverable (sometimes more than one), which can be a standard or a specification, a guide or a report.
ETSI has a suite of specifications, standards and reports that fulfil the various needs of the market, viz.
- ETSI TS (ETSI Technical Specification) and ETSI TR (ETSI Technical Report) - adopted by the responsible Technical Body
- ETSI ES (ETSI Standard) and ETSI EG (ETSI Guide) - adopted after ETSI membership weighted voting
- ETSI EN (European Standard) - adopted after ETSI membership national weighted voting
- ETSI SR (ETSI Special Report) - an information document used for various purposes, including giving public availability to information not produce within a Technical Body
- ETSI GS (ETSI Group Specification) and GR (ETSI Group Report) - produced by an Industry Specification Group
This suite of deliverables fulfils the needs for
- high quality specifications delivered early to the market (ETSI TS)
- high quality standards supported by the whole ETSI global membership (ETSI ES)
- European harmonization (ETSI EN).
The numbering convention used by ETSI to link related documents at these various "levels" simplifies their market application.
