This 3rdedition of EN 50173-1 replaces the text of EN 50173-1:2007, EN 50173-1:2007/A1:2009 and consolidates these two standards with the text of EN 50173-1:2007/FprAB:2010 for the convenience of the user of the standard. The text
12、of draft amendment EN 50173-1:2007/FprAB was submitted to the Formal Vote and was approved by CENELEC to amend EN 50173-1:2007 on 2011-04-01. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and CENELEC shall not be held respon
13、sible for identifying any or all such patent rights. 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) 2012-04-01 latest date by which the national standards conflicting with th
14、e EN have to be withdrawn (dow) 2014-04-01 The previous editions of European Standards EN 50173:1995 and EN 50173-1:2002 have been developed to enable the application-independent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
15、 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 ENs are published as individual parts of the series EN
16、 50173, thus also acknowledging that standards users recog-nize 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
