Rules of Procedures and Working Procedures have been prepared
for the work of ETSI. These procedures describe the document
types that ETSI produces, formal rules for the presentation
of the content of these documents, and rules for the approval of
the documents.
The document types ETSI produce are
- European Telecommunication Standards (ETS)
- Interim European Telecommunication Standards (I-ETS)
- Technical Bases for Regulation (TBR)
- ETSI Technical Reports (ETRs)
- Technical Committee Reference Technical Reports (TCR-
TR)
- Technical Committee Technical Reports (TC-TR).

Both ETSs and I-ETSs are standards. The approval procedures
for ETSs and I-ETSs are identical.
The life of an I-ETS is limited to three years after which it can

Maintenance of (Interim) Standards
Whilst every care is being taken in the preparation and
publication of ETSI (Interim) Standards, there is always
a need for maintenance of approved (Interim) Standards.
The maintenance may result in either
a) an Amendment to the current Edition, or
b) a new Edition.
A decision to modify an adopted standard follows the
ETSI rules for creating a new work item. At the time of
creating a new work item it is not necessary to decide
whether the result will be published as an Amendment
document or a new Edition.
In general, the following rules apply:
- Amendments shall be avoided whenever possible.
They may only be issued in cases of urgently needed
improvements of the (Interim) Standard.

A standard is given the I-ETS status either because it is regarded
as a provisional solution ahead of a more advanced standard,
or because it is immature and requires a “trial period”.
Where ETSI has decided to start work on a standard, there is an
obligation on all ETSI countries and individuals not to undertake
activities which could prejudice the preparation of the ETS
defined by the scope statement of the work item. It should be
noted that such activities may include not only the preparation
of standards, but also that of new or revised technical specifications
to support national regulations. These rules, which often
are referred to as “Standstill” do not apply to work where the
intention is to prepare an I-ETS.
There are three possible approval procedures for standards:
- Normal Approval Procedure (NAP)
- Unified Approval Procedure (UAP)
- No more than three amendments shall be issued to
a single Edition of an (Interim) Standard.
- A new Edition shall be published wherever the size
of the text of the amendment approaches 10 % to
15 % of the original text.
Where a new edition is published details about earlier
editions shall be contained in the foreword of the document.
The number of the edition shall be indicated on
the title page of the (Interim) Standard.
All amendments shall have a title page similar to that of
the (I-)ETS.
The approval procedure of Amendments or new Editions
is normally the UAP. In cases where significant
changes to the (I-)ETS are being proposed, the NAP
should be used.
