Test methods and requirements for accessories for use on distribution cables of rated voltage 0,6/1,0 (1,2) kV
This European Standard details the performance requirements and the test methods for type tests for cable accessories for use on cables of rated voltage 0,6/1,0 (1,2) kV as defined in HD 603. Formerly, approvals for such products have been achieved on the basis of national standards and specifications and/or the demonstration of satisfactory service performance. The publication of this European standard does not invalidate existing approvals. However, products approved to such earlier standards or specifications shall not claim approval to this European Standard unless specifically tested to it. After they have been successfully made, these tests need not be repeated unless changes are made in the cable accessory materials, design or manufacturing process which might affect the performance characteristics. Joints, stop ends and outdoor terminations for extruded solid dielectric insulated cables and transition joints between extruded solid dielectric insulated and impregnated paper insulated cables are included. Joints, stop ends and outdoor terminations for impregnated paper insulated cables are not included. The service operating conditions of accessories shall be compatible with the service operating conditions of the cable. Accessories for special applications such as submarine cables, shipboard application or hazardous situations (explosive environments, fire resistant cables or seismic conditions) are not included.
Prüfverfahren und Prüfanforderungen für die Garnituren von Verteilerkabeln mit einer Nennspannung von 0,6/1,0 (1,2) kV
Diese Europäische Norm führt die Prüfverfahren und Mindestanforderungen für die Typenprüfungen an Kabelgarnituren für Kabel mit Nennspannungen 0,6/1,0 (1,2) kV, wie in HD 603 beschrieben, auf. In der Vergangenheit erfolgte die Zulassung von Garnituren auf der Basis nationaler Normen und Bedingungen und/oder dem Nachweis hinreichender Betriebsergebnisse. Durch die Veröffentlichung dieser Europäischen Norm werden bestehende Zulassungen nicht ungültig. Jedoch gelten Garnituren, typgeprüft nach früheren Normen oder Bedingungen, nicht als nach dieser Europäischen Norm typgeprüft, solange sie nicht diesem entsprechend geprüft wurden. Nachdem die Prüfung bestanden wurde, braucht diese nicht wiederholt werden, es sei denn, Änderungen in Material, Konstruktion oder Herstellprozess, welche die Betriebseigenschaften beeinflussen können, wurden vorgenommen. Muffen, Endmuffen und Freiluft-Endverschlüsse für extrudierte, kunststoffisolierte Kabel und Übergangsmuffen zwischen extrudierten, kunststoffisolierten Kabeln und Kabeln mit massegetränkter Papierisolierung sind enthalten. Nicht enthalten sind Muffen, Endmuffen und Freiluft-Endverschlüsse für Kabel mit massegetränkter Papierisolierung. Die Betriebsbedingungen für Garnituren müssen denen der Kabel angepasst sein. Diese Norm gilt nicht für Garnituren für spezielle Anwendungsbereiche, z.B. Seekabel, Schiffskabel oder für den Einsatz unter gefährlichen Bedingungen (explosive Umgebung, feuerbeständige Kabel oder Erdbebengefährdung).
Méthodes et prescriptions d'essai pour les accessoires de câbles de distribution de tension assignée 0,6/1,0 (1,2) kV
La présente Norme Européenne définit les méthodes et les prescriptions d’essais de type pour les accessoires utilisés sur les câbles de tension assignée 0,6/1,0 (1,2) kV définis par le HD 603. Antérieurement, les acceptations des produits ont été prononcées sur la base de normes et spécifications nationales et/ou la démonstration d’un comportement satisfaisant en service. La publication de la présente Norme Européenne ne remet pas en cause les acceptations existantes. Toutefois, les produits acceptés selon les normes ou spécifications antérieures ne doivent se prévaloir d’une acceptation selon la présente Norme Européenne que s’ils ont été essayés spécifiquement selon les modalités qui y sont indiquées. Une fois ces essais effectués avec succès, il n’est pas nécessaire de les répéter, à moins que des modifications n’aient été introduites dans les matériaux de l’accessoire, dans sa conception ou dans son procédé de fabrication, susceptibles d’en modifier les caractéristiques de fonctionnement. Elle concerne à la fois les jonctions et les dérivations, les bouts perdus et les extrémités extérieures pour câbles à isolant synthétique et les jonctions de transition entre câbles à isolant synthétique et câbles isolés au papier imprégné. Elle ne concerne pas les jonctions et les dérivations, les bouts perdus et les extrémités extérieures pour câbles isolés au papier imprégné. Les conditions d'exploitation des accessoires doivent être compatibles avec celles des câbles. Les accessoires pour câbles spéciaux tels que les câbles sous-marins, les câbles de bord des navires, les câbles pour environnement dangereux (risques d'explosion, d'incendie, de secousses sismiques) ne sont pas traités.

This European Standard was approved by CENELEC on 2005-10-01. CENELEC members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard the status of a national standard without any alteration.
Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the Central Secretariat or to any CENELEC member.
This European Standard exists in three official versions (English, French, German). A version in any other language made by translation under the responsibility of a CENELEC member into its own language and notified to the Central Secretariat has the same status as the official versions.
CENELEC members are the national electrotechnical committees of Austria, Belgium, Cyprus, the Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom.
The text of the draft was submitted to the formal vote and was approved by CENELEC as EN 50393 on 2005-10-01. This European Standard supersedes HD 623 S1:1996 and its amendment A1:2001. This European Standard is the first revision of HD 623 S1:1996 and includes the first amendment A1:2001 and the changes proposed by the CLC/TC 20 WG 11, Harmonisation of joints, accessories and terminations of electric cables.
CLC/TC 20, at its meeting in Stockholm (May 2002), agreed that HD 623 should be converted to an EN. This European Standard has been written as part of a series of standards to satisfy the Public Procurement Directive, and is complementary to HD 603, which covers cables rated at 0,6/1,0 (1,2) kV for use by distributors of electrical power. The following dates were fixed: – latest date by which the EN has to be implemented at national level by publication of an identical national standard or by endorsement
