IEC 60502-4:2010
(Main)Power cables with extruded insulation and their accessories for rated voltages from 1 kV (Um = 1,2 kV) up to 30 kV (Um = 36 kV) - Part 4: Test requirements on accessories for cables with rated voltages from 6 kV (Um = 7,2 kV) up to 30 kV (Um = 36 kV)
Power cables with extruded insulation and their accessories for rated voltages from 1 kV (U<sub>m</sub> = 1,2 kV) up to 30 kV (U<sub>m</sub> = 36 kV) - Part 4: Test requirements on accessories for cables with rated voltages from 6 kV (U<sub>m</sub> = 7,2 kV) up to 30 kV (U<sub>m</sub> = 36 kV)
IEC 60502-4:2010 specifies the test requirements for type testing of accessories for power cables with rated voltages from 3,6/6 (7,2) kV up to 18/30 (36) kV, complying with IEC 60502-2. Accessories for special applications, such as aerial cables, submarine or ship cables or hazardous situations (explosive environments, fire-resistant cables or seismic conditions), are not included. It is not necessary to repeat these tests, once successfully completed, unless changes are made in the materials, design or manufacturing process which might affect the performance characteristics. Test methods are included in IEC 61442. Significant technical changes with respect to the previous edition are as follows:
a) the range of approval has been revised;
b) a water immersion test requirement for outdoor terminations has been introduced;
c) examination of accessories at the end of the test sequence is to be recorded in a test report for information only;
d) both the a.c. and d.c. test are to be carried out;
e) the heating cycle test has been added to Table 11.
Câbles d'énergie à isolant extrudé et leurs accessoires pour des tensions assignées de 1 kV (U<sub>m</sub> = 1,2 kV) à 30 kV (U<sub>m</sub> = 36 kV) - Partie 4: Exigences d'essai pour accessoires de câbles de tensions assignées de 6 kV (U<sub>m</sub> = 7,2 kV) à 30 kV (U<sub>m</sub> = 36 kV)
La CEI 60502-4:2010 définit les exigences d'essais de type des accessoires de câbles d'énergie de tensions assignées de 3,6/6 (7,2) kV à 18/30 (36) kV conformes à la CEI 60502-2. Les accessoires pour des applications spéciales telles que les câbles aériens, sous-marins ou de bord ou les situations à risque (environnements explosifs, câbles résistant au feu, ou conditions séismiques) ne sont pas couverts par cette norme. Il n'est pas nécessaire de répéter ces essais lorsqu'ils ont été effectués avec succès, sauf si des changements interviennent dans les matériaux, la constitution ou le procédé de fabrication, susceptibles d'affecter les caractéristiques de fonctionnement. Les méthodes d'essais figurent dans la CEI 61442. Cette troisième édition annule et remplace la deuxième édition, publiée en 2005, et constitue une révision technique. Les changements significatifs par rapport à l'édition précédente sont les suivants:
a) le domaine d'application a été révisé;
b) un essai d'immersion dans l'eau a été introduit pour les extrémités externes;
c) l'examen des accessoires à la fin de la séquence d'essai est à enregistrer dans le rapport d'essai pour information seulement;
d) les deux essais de tenue diélectrique en courant alternative et courant continue sont à affectuer;
e) l'essai de cycles thermiques a été ajouté au Tableau 11.

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 itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services
and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent
certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibil
