This European Standard was approved by CENELEC on 2005-11-01. CENELEC members are bound to
comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European
Standard the status of a national standard without any alteration.
Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat or to any CENELEC member.
This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and
notified to the Central Secretariat has the same status as the official versions.
CENELEC members are the national electrotechnical committees of Austria, Belgium, Cyprus, Czech
Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia,
Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden,
Switzerland and United Kingdom.

Foreword
The text of document 3/753/FDIS, future edition 2 of IEC 61175, prepared by IEC TC 3, Information
structures, documentation and graphical symbols, was submitted to the IEC-CENELEC parallel vote
and was approved by CENELEC as EN 61175 on 2005-11-01.
This European Standard supersedes EN 61175:1993.
It includes the following significant technical changes with respect to EN 61175:1993:
The structure of the signal designation has been extended and specified in more detail:
– the term “item designation” has been replaced by “reference designation” with the same meaning
as before;
– the term “basic signal name” has been extended. It has been replaced by “signal name”; then
subsequently consisting of “class”, “short name” and “basic signal name”, where “basic signal
name” has the same meaning as before;
– classification codes have been introduced in order to facilitate the understanding of the signal
name, for example the type of signal and hence the “signal direction” can be recognized by the
code;
– the concept of “signal name domain” has been introduced for improved identification of signal
name in relation to an applicable object;
– the term “version identifier” has been changed to “variant” with the same meaning as before;
– the earlier possibility to provide additional information on “signal level” has been generalized to an
area of “additional information” to be used to supplement information on “version”, “time stamp”,
“level” and other system related parameters. The additional information is stated to belong to a
variant of the signal (not to the signal designation in general).
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2006-08-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2008-11-01
Annex ZA has been added by CENELEC.
