This standard belongs to the series of testing standards for fiber optic cables. DIN EN 60794-1-2 in the 2017 edition has been split by IEC Technical Subcommittee 86A into a series of standards of individual tests to provide better and faster updates.
In accordance with IEC Secretariat guidelines, a new format for numbering test methods has been agreed upon to facilitate cross-referencing from old to new and to facilitate updating of the corresponding framework and product specifications.
The agreed format is: IEC 60794-1-Xnn, where X is the 2nd digit of the old two-digit reference, nn is an incremental number (starting with the number of the old test method)
An annex has been added to IEC60794-1-2 that provides a cross-reference between the old and new numbering schemes.
This part of IEC 60794 applies to optical ground wires (OPGW) and optical phase conductors (OPPC).
An Optical Phase Conductor (OPPC) is used as an alternative telecommunication solution when a ground wire is not available, i.e. an Optical Ground Wire (OPGW - a dual purpose cable, i.e. it serves two purposes. It is designed to replace traditional static / shielded / ground wires on overhead lines, with the added benefit of containing optical fibers that can be used for telecommunications purposes) is not a viable option.
The basic design is similar to conventional OPGW, except that it is designed to simulate the mechanical and electrical properties of the phase conductor it replaces. Unlike OPGW, where the cable does not carry continuous current, OPPC is powered by high-voltage lines. Therefore, it requires specially adapted splice boxes and insulators to meet the conditions of the live line.
This document defines a test standard for determining the ability of a cable to withstand the effects of a controlled salt atmosphere.
Thus, the standard provides investment security for manufacturers and users and gives test laboratories and manufacturers defined information for testing.
