Electric cables - Additional test methods
Electric cables - Additional test methods
This HD collates and specifies the test methods to be used for testing polymeric insulated and sheathed electric cables, of rated voltage up to and including 20, 8/36 kV, intended for public distribution systems, and for use in power generating plants and sub-stations. Test methods in this HD are additional to those already harmonised, e.g. EN 60332-1 series and EN 60811 series, and are used for testing cable types specified in HD 603, HD 604, HD 620, HD 622, HD 626 and HD 627. In each case, these HDs give complementary information needed for the practical application to each specific type. Therefore the present HD as such is not sufficient for carrying out and evaluating the tests on electric cables. Full test conditions (e.g. temperatures, durations) and/or test requirements are not specified in this HD. Such data needed to carry out the tests is given in the particular sections. NOTE The words 'particular section' refer throughout to the section of HD 603 or HD 604, or other HD to which HD 605 applies, in which a particular cable type is specified.
Starkstromkabel - Ergänzende Prüfverfahren
Dieses HD fasst zusammen und legt die Prüfverfahren fest, die zum Prüfen von polymerisolierten und ummantelten elektrischen Kabeln mit Nennspannungen bis einschließlich 20,8/36 kV anzuwenden sind, die für öffentliche Verteilersysteme sowie für die Verwendung in Kraftwerken und Umspannwerken vorgesehen sind. Die Prüfverfahren in diesem HD ergänzen die bereits harmonisierten, z. B. EN 60332-1 (Reihe) und EN 60811 (Reihe), und werden zum Prüfen der Kabeltypen verwendet, die im HD 603, HD 604, HD 620, HD 622, HD 626 und HD 627 festgelegt sind. In jedem Falle vermitteln diese HD zusätzliche Informationen, die für die praktische Anwendung auf jeden spezifischen Typ benötigt werden. Daher ist das vorliegende HD selbst nicht ausreichend, um die Prüfungen an elektrischen Kabeln durchzuführen und auszuwerten. Die vollständigen Prüfbedingungen (z. B. Temperaturen, Zeit) und/oder Prüfanforderungen werden im vor-liegenden HD nicht festgelegt. Derartige Daten, die zur Durchführung der Prüfungen erforderlich sind, werden in den Hauptabschnitten angegeben. ANMERKUNG Der Begriff „Hauptabschnitt“ bezieht sich ausnahmslos auf den Abschnitt im HD 603 oder HD 604 oder andere HD, auf die sich das HD 605 bezieht, in welchen ein spezieller Kabeltyp festgelegt ist.
Câbles électriques - Méthodes d’essais supplémentaires
NOTE Ce Document d’Harmonisation regroupe et définit les méthodes d’essais des câbles électriques isolés et gainés avec des matériaux polymères, de tension assignée 20,8/36 kV, destinés aux réseaux de distribution publique, aux centrales électriques et aux sous-stations. Les méthodes d’essais du présent HD viennent en complément des méthodes déjà harmonisées, comme celles des séries EN 60332-1 et EN 60811, et celles utilisées pour l’essai des câbles définis dans les HD 603, HD 604, HD 620, HD 622, HD 626 et HD 627. Dans chaque cas, ces HD donnent des informations complémentaires nécessaires pour l’application pratique à chaque type de câble. Le présent HD tel quel n’est donc pas suffisant pour effectuer les essais et évaluer les câbles électriques. Les conditions d’essais (par exemple: températures, durées) et les prescriptions correspondantes ne sont pas spécifiées dans leur intégralité dans ce HD. Ces données, nécessaires à la réalisation des essais, figurent dans les sections particulières. NOTE L’expression «sections particulières» fait référence aux sections des HD 603 ou HD 604 ou aux autres HD auquel le HD 605 s’applique, dans lequel un type de câble particulier est défini.

Foreword
This Harmonization Document was prepared by the Technical Committee CENELEC TC 20, Electric cables.
The text of the draft was submitted to the Unique Acceptance Procedure and was approved by CENELEC as
HD 605 S2 on 2008-03-01.
This Harmonization Document supersedes HD 605 S1:1994 + A1:1996 + A2:2001 + A3:2002 + A4:2004.
It provides a full updating of edition 1, including incorporation of amendments 1, 2, 3 and 4 together with the
results from rationalisation of “Harder to harmonise” tests.
In order to maintain the integrity of existing clause numbers, and hence avoid unnecessary amendments to over
100 particular sections of the product HDs, the normative references are given in Annex A.
The numbering of tables and figures in this standard is not conventional. It retains the scheme as used in
HD 605 S1. This is to facilitate easier cross referencing in national sections of HD 603, HD 620 and other
compendia HDs. It also allows for continuing work to rationalise and harmonise more of these test methods in
the future, without the need for further re-numbering.
The following dates were fixed:
– latest date by which the existence of the HD
has to be announced at national level (doa) 2008-09-01
– latest date by which the HD has to be implemented
at national level by publication of a harmonized
national standard or by endorsement (dop) 2009-03-01
– latest date by which the national standards conflicting
with the HD have to be withdrawn (dow) 2009-03-01
