IEC 60794-2-20:2013 is a family specification covering multi-fibre optical cables for indoor use. The requirements of the sectional specification IEC 60794-2 are applicable to cables covered by this standard. Annex B contains a Blank Detail Specification and general guidance in case the cables are intended to be used in installation governed by the MICE table of ISO\/IEC 24702 (Industrial premises). This third edition cancels and replaces the second edition published in 2008 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: – removal of Annex C; – reference to the most recent fibre standards; – reference to the new series IEC 60794-1-2X. Keywords: family specification covering multi-fibre optical cables for indoor use This publication is to be read in conjunction with \/2, \/2 and \/2.<\/p>\n
