Foreword
The text of document 86A/880/FDIS, future edition 2 of IEC 60793-2-50, prepared by SC 86A, Fibres
and cables, of IEC TC 86, Fibre optics, was submitted to the IEC-CENELEC parallel vote and was
approved by CENELEC as EN 60793-2-50 on 2004-04-01.
This European Standard supersedes EN 60793-2-50:2002.
The principle change relative to EN 60793-2-50:2002 is the addition of environmental testing
requirements. Additionally, the requirements in Annex C have been clarified.
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) 2005-01-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2007-04-01
Annex ZA has been added by CENELEC.
The contents of the corrigendum of July 2004 have been included in this copy.
