This Part 24, which specifies particular requirements for conduit systems buried underground, is to be

used in conjunction with EN 61386-1, Conduit systems for cable management – Part 1: General

Requirements, and its amendments. It was established on the basis of the first edition (2004) of that

standard and its Amendment 1 (2000).

This Part 24 supplements or modifies the corresponding clauses of EN 61386-1. Where a particular

clause or subclause of Part 1 is not mentioned in this Part 24, that clause or subclause applies as far as

is reasonable. Where this Part 24 states "addition", "modification" or "replacement", the relevant text of

Part 1 is to be adapted accordingly.

Subclauses, tables and figures which are in addition to those in Part 1 are numbered starting with 101.

A conduit system which complies with this standard, is deemed safe for use when installed in accordance

with national wiring regulations, whilst applying the manufactures installation instructions and conduit

classification.
NOTE The following print types are used:
− requirements: in roman type
− test specifications: in italic type
− notes: in small roman type

EN 61386 consists of the following parts, under the general title Conduits systems for cable management:

Part 1: General requirements
Part 21: Particular requirements – Rigid conduit systems
Part 22: Particular requirements – Pliable conduit systems
Part 23: Particular requirements – Flexible conduit systems
Part 24: Particular requirements – Conduit systems buried underground

FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote

international co-operation on all questions concerning standardization in the electrical and electronic fields. To

this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,

Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC

Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested

in the subject dealt with may participate in this preparatory work. International, governmental and non-

governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely

with the International Organization for Standardization (ISO) in accordance with conditions determined by

agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all

interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence

between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in

the latter.
