This part of IEC 60794 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 the environmental performance.

Throughout the standard the wording “optical cable” may also include optical fibre units,
microduct fibre units, etc.

See IEC 60794-1-2 for general requirements and definitions and reference guide to test
methods of all types.
