Conduit systems for cable management - Outside diameters of conduits for electrical installations and threads for conduits and fittings

This International Standard specifies outside diameters for conduits used in electrical installations or in communication systems and the dimensional requirements for threads. It also specifies the dimensional requirements for threads used in associated fittings. It is not applicable to extra heavy-duty electrical rigid steel conduits specified in IEC 60981.

Systèmes de conduits pour la gestion du câblage - Diamètres extérieurs des conduits pour installations électriques et filetages pour conduits et accessoires

La présente Norme internationale spécifie les diamètres extérieurs des conduits utilisés dans les installations électriques ou dans les systèmes de communication ainsi que les exigences dimensionnelles des filetages. Elle spécifie aussi les exigences dimensionnelles des filetages utilisés dans les accessoires associés. Elle ne s'applique pas aux conduits très lourds rigides en acier conformes à la CEI 60981 Cette troisième édition annule et remplace la seconde édition publiée en 1993. Cette édition constitue une révision technique. Les modifications principales suivantes à la seconde édition ont été réalisées: -révision des figures et des tableaux, mise à jour des références normatives et corrections éditoriales; -accroissement à 110 mm du diamètre extérieur des conduits.

Foreword

The text of document 23A/541/FDIS, future edition 3 of IEC 60423, prepared by SC 23A, Cable

management systems, of IEC TC 23, Electrical accessories, was submitted to the IEC-CENELEC parallel

vote and was approved by CENELEC as EN 60423 on 2007-10-01.
This European Standard supersedes EN 60423:1994.
The following main changes have been made to EN 60423:1994:
– revised figures and tables plus editorial and normative reference updates;
– conduit range increased to 110 mm outside diameter.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
(dop) 2008-07-01
national standard or by endorsement
– latest date by which the national standards conflicting
(dow) 2010-10-01
with the EN have to be withdrawn
Annex ZA has been added by CENELEC.

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.

5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any

equipment
