UNE-EN IEC 60794-1-215:2020

This part of IEC 60794-1 defines test procedures to be used in establishing uniformrequirements for the environmental performance of" optical fibre cables for use with telecommunication equipment and devices employingsimilar techniques, and" cables having a combination of both optical fibres and electrical conductors.Throughout the standard the wording "optical cable" can also include optical fibre units,microduct fibre units, etc.This part defines a test standard to determine the ability of a cable to withstand the effects offreezing water that can immediately surround the optical fibre cable sheath by observing anychanges in the physical appearance of the sheath, or in the measured cable opticalattenuation.Method F15A is a test standard to simulate freezing of the medium surrounding a buried cable,as in wet earth or water. Method F15A is moved from Method F15 in IEC 60794-1-22, Ed. 2without any technical changes.Method F15B is a test standard to simulate freezing of the medium surrounding an outsidecable in a conduit (duct) which is made of rigid material, e.g. steel.See IEC 60794-1-2 for a reference guide to test methods of all types and for generalrequirements.
