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 testing of cable accessories for use with power distribution cables of rated voltage 0,6/1,0 (1,2) kV as defined in HD 603 or other relevant cable standards. Cable accessories covered by this European Standard include 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. Joints, stop ends and outdoor terminations for impregnated paper insulated cables are not included. The service operating conditions of accessories should be compatible with the service operating conditions of cables on which they are to be installed. Accessories for special applications such as submarine, shipboard, explosive or seismic environments, or where specified fire performance characteristics are required, are not included. NOTE 1 This European Standard does not invalidate existing approvals of products achieved on the basis of national standards and specifications and/or the demonstration of satisfactory service performance. However, products approved according to such national standards or specifications cannot directly claim approval to this European standard. NOTE 2 It may be possible, subject to agreement between supplier and purchaser, and/or the relevant conformity assessment body, to demonstrate that conformity to the earlier standard can be used to claim conformity to this European Standard, provided an assessment is made of any additional type testing that may need to be carried out. Any such additional testing that is part of a sequence of testing cannot be done separately.
Prüfverfahren und Prüfanforderungen für die Garnituren von Verteilerkabeln mit einer Nennspannung von 0,6/1,0 (1,2) kV
Diese Europäische Norm beschreibt Prüfverfahren und Mindestanforderungen für die Typprüfungen an Kabelgarnituren für Energieverteilungskabel mit Nennspannungen 0,6/1,0 (1,2) kV, wie in HD 603 bzw. anderen Normen für entsprechende Kabel festgelegt. Die in dieser Europäischen Norm behandelten Kabelgarnituren umfassen Muffen, Endmuffen und Freiluft-Endverschlüsse für extrudierte, kunststoffisolierte Kabel und Übergangsmuffen zwischen extrudierten, kunststoffisolierten Kabeln und Kabeln mit massegetränkter Papierisolierung. Nicht enthalten sind Muffen, Endmuffen und Freiluft-Endverschlüsse für Kabel mit massegetränkter Papierisolierung. Die Betriebsbedingungen für Garnituren sollten denen der Kabel angepasst sein, auf denen sie installiert werden. Diese Norm gilt nicht für Garnituren für spezielle Anwendungsbereiche, z.B. für Seekabel, Schiffskabel oder für den Einsatz in explosiver bzw. erdbebengefährdeter Umgebung oder einer Umgebung, in der besondere Leistungsparameter bezüglich der Feuerbeständigkeit erforderlich sind. ANMERKUNG 1 Durch diese Europäische Norm werden bestehende Zulassungen von Produkten nicht ungültig, die auf der Grundlage nationaler Normen und Spezifikationen und/oder des Nachweises der Funktionssicherheit erlangt wurden. Jedoch können nach nationalen Normen oder Spezifikationen zugelassene Garnituren nicht automatisch beanspruchen, als nach dieser Europäischen Norm zugelassen zu gelten. ANMERKUNG 2 Sofern eine Bewertung aller notwendigen Typprüfungen, die zusätzlich durchgeführt werden müssen, vorliegt, ist durch eine Vereinbarung zwischen Lieferant und Kunde und/oder der entsprechenden Konformitätsbewertungsstelle das Erbringen eines Nachweises der Konformität zu der früheren Norm möglich, um als nach dieser Europäischen Norm zugelassen zu gelten. Zusätzliche Prüfungen, die Teil einer Prüffolge sind, dürfen nicht als gesonderte Prüfung durchgeführt werden.
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 exigences de performance et les méthodes d’essai de type pour les accessoires utilisés sur les câbles de distribution d’énergie de tension assignée 0,6/1,0 (1,2) kV définis par le HD 603 ou d'autres normes de câbles applicables. Les accessoires de câbles couverts par la présente Norme Européenne incluent les jonctions et dérivations, les bouts perdus et les extrémités extérieures pour câbles à isolant synthétique extrudé et les jonctions de transition entre câbles à isolant synthétique extrudé 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. Il convient que les conditions d'exploitation des accessoires soient compatibles avec celles des câbles sur lesquels ils sont à installer. Les accessoires pour des applications spécifiques telles que les applications sous-marines, à bord des navires, ou bien des environnements présentant des risques d'explosions ou sismiques, ou dans le cas d'exigences de tenue au feu spécifiées ne sont pas inclus. NOTE 1 La présente Norme Européenne ne remet pas en cause les agréments existants des produits obtenus selon des normes et spécifications nationales et/ou la démonstration d’un comportement satisfaisant en service. Toutefois, les produits approuvés selon lesdites normes ou spécifications nationales ne peuvent prétendre directement à l'agrément selon la présente Norme Européenne. NOTE 2 Il peut être possible, selon accord entre le fournisseur et l'acheteur, et/ou l'organisme d'évaluation de la conformité correspondant, de démontrer que la conformité avec la norme antérieure peut être utilisée pour prétendre à la conformité à la présente Norme Européenne, à condition que soit réalisée une évaluation de tout essai de type supplémentaire pouvant être nécessaire. Tout essai supplémentaire de cet ordre faisant partie d'une séquence d'essais ne peut être effectué séparément.
Preskusne metode in zahteve za pribor, ki se uporablja na distribucijskih kablih za naznačeno napetost 0,6/1,0 (1,2) kV
Ta evropski standard podrobno opisuje zahteve glede zmogljivosti in preskusne metode za tipsko preskušanje dodatkov kablov, ki se uporabljajo z distribucijskimi kabli naznačene napetosti 0,6/1,0 (1,2) kV, kot je opredeljeno v standardu HD 603 ali drugih ustreznih standardih za kable.
Med dodatke kablov, ki jih zajema ta evropski standard, spadajo spojke, slepi končniki in zunanji priključki za kable, izolirane z ekstrudiranim trdnim dielektrikom in prehodne spojke med kabli, izoliranimi z ekstrudiranim trdnim dielektrikom in kabli, izoliranimi z impregniranim papirjem. Spojke, slepi končniki in zunanji priključki za kable, izolirane z impregniranim papirjem, niso vključeni.
Pogoji uporabe dodatkov morajo biti v skladu s pogoji uporabe kablov, na katere bodo nameščeni.
Dodatki, namenjeni posebni uporabi, na primer pod vodo, na ladji ali v eksplozivnih ali potresnih okoljih, ali uporabi, pri kateri so potrebne določene posebne lastnosti ob požaru, niso vključeni. OPOMBA 1 Ta evropski standard ne izniči obstoječih odobritev izdelkov, prejetih na podalgi nacionalnih standardov in specifikacij in/ali prikazu zadovoljivega delovanja. Vendar izdelki, odobreni na podlagi omenjenih nacionalnih standardov ali specifikacij, se ne morejo neposredno sklicevati na odobritev tega evropskega standarda.
OPOMBA 2 Odvisno od dogovora med dobaviteljem in kupcem in/ali ustreznim telesom za ocenjevanje skladnosti, je mogoče prikazati, da se lahko skladnost s prejšnjimi standardi uporabi za sklicevanje na skladnost s tem evropskim standardom, če se predhodno oceni, ali je potrebno izvesti dodatne tipske preskuse. Dodatnih preskusov, ki so del zaporedja preskusov, ni mogoče izvesti posebej.
