Standards Development
This part of IEC 60794 contains test procedures, referred to as Method E24, for evaluating the behaviour of microduct cabling (outdoor/indoor microduct optical cable, fibre unit or hybrid cable etc.) when blown into an outdoor microduct, protected outdoor microduct or indoor microducts
This document describes two blowing track layouts which are suitable for testing of outdoor microduct cables as well a track to be used for testing of indoor microduct cables: Method A consists of two mandrels and two long straight sections in between (same curvature). Method B consists of 3 mandrels. The middle mandrel forces the cable to experience both left- and right-hand bending, which is a feature of any realistic blowing route. For indoor cable testing Method C which is similar to Method B is described.
In addition, this document describes an optional procedure to check the capability of blowing out an installed cable.
