1   Scope

  This part of [IEC 60794](/search?q=IEC%C2%A060794)
   applies to optical fibre cables for use with telecommunication equipment and devices
  employing similar techniques, as well as hybrid telecommunication cables having a
  combination of both optical fibres and electrical conductors. 
The object of this document is to define test procedures to be used in establishing
  uniform requirements for the material compatibility performance of cables, cable components,
  and cable subassemblies. 
Compatibility of materials within a cable has the potential to involve a range of
  material pairs. However, experience has shown that the most pertinent evaluations
  are of the cable filling and flooding materials' interactions with other materials
  in the cable. 

    NOTE  Throughout the document the wording “optical cable” can also include optical fibre
     units, microduct fibre units, etc. 

See [IEC 60794‑1‑2](/search?q=IEC%C2%A060794%E2%80%911%E2%80%912) for general requirements and definitions, as well as for a reference guide to test
  methods of all types.
