    Abstract - (Show below) - (Hide below)

    IEC 60794-1-21:2015(E) applies to optical fibre cables for use with telecommunication equipment and devices employing similar techniques, and to cables having a combination of both optical fibres and electrical conductors. The object of this standard is to define test procedures to be used in establishing uniform requirements for mechanical requirement performance. Throughout this standard the wording "optical cable" may also include optical fibre units, microduct fibre units, etc. General requirements and definitions are given in IEC 60794-1-20 and a complete reference guide to test method of all types in the IEC 60794-1-2. This first edition of IEC 60794-1-21 cancels and replaces the mechanical tests part of the second edition of IEC 60794-1-2, published in 2003. It constitutes a technical revision. Keywords: optical fibre cables for use with telecommunication equipment, test procedures
