This part of IEC 60794 contains test procedures, referred to as Method E24, for evaluating the behaviour of microduct cabling (microduct optical cable, fibre unit or hybrid cable etc.) when blown into a microduct or protected microduct.

This document describes two blowing track layouts: 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.

In addition, this document describes an optional procedure to check the capability of blowing out an installed cable.
