This European Standard was approved by CENELEC on 2007-04-11. 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, Bulgaria, Cyprus, the Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom.
EN 50173-1:2007 – 2 – Foreword This European Standard was prepared by the Technical Committee CENELEC TC 215, Electrotechnical aspects of telecommunication equipment.
The text of the draft was submitted to the formal vote and was approved by CENELEC as EN 50173-1 on 2007-04-11. 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)
2008-05-01 – latest date by which the national standards conflicting with the EN have to be withdrawn
(dow)
2010-05-01 The previous editions of European Standards EN 50173:1995 and EN 50173-1:2002 have been developed to enable the application-independent cabling to support ICT applications in office premises. Their basic principles, however, are applicable to other types of applications and in other types of premises.
TC 215 has decided to establish relevant European Standards which address the specific requirements of these premises. In order to point out the commonalities of these cabling design standards, these EN are published as individual parts of the series EN 50173, thus also acknowledging that standards users recognize the designation “EN 50173” as a synonym for generic cabling design.
At the time of publication of this European Standard, series EN 50173 comprises the following standards: EN 50173-1 Information technology – Generic cabling systems – Part 1: General requirements EN 50173-2 Information technology – Generic cabling systems – Part 2: Office premises EN 50173-3 Information technology – Generic cabling systems – Part 3: Industrial premises EN 50173-4 Information technology – Generic cabling systems – Part 4: Homes EN 50173-5 Information technology – Generic cabling systems – Part 5: Data centres This European Standard, EN 50173-1, together with EN 50173-2:2007 supersedes EN 50173-1:2002. This standard contains those specifications of EN 50173-1:2002, which are common to generic cabling systems irrespective of the type of premises. This European Standard also
- introduces the concept of environmental classification (Subclause 5.1); - specifies additional channels for balanced and optical fibre cabling media; - specifies additional channels for coaxial cabling; - specifies the minimum component requirements in support of these additional cabling channels; - extends and amends the list of applications supported by generic cabling systems.
