Unter den verschiedenen verf\u00fcgbaren Schutzrohrmaterialien zeichnet sich PVC (Polyvinylchlorid) aufgrund seiner Flexibilit\u00e4t, Korrosionsbest\u00e4ndigkeit und einfachen Installation als beliebte Wahl aus. Die Norm IEC 61386 liefert wichtige Richtlinien f\u00fcr die Klassifizierung und die Leistungsanforderungen von Schutzrohrsystemen und gew\u00e4hrleistet so die Einhaltung globaler Sicherheits- und Zuverl\u00e4ssigkeitsstandards.<\/p>\n<p>Ob Wohn-, Gewerbe- oder Industrieprojekt: Das Verst\u00e4ndnis der Spezifikationen und Vorteile von Leitungsrohren gem\u00e4\u00df IEC 61386 ist entscheidend f\u00fcr fundierte Entscheidungen. Dieser Artikel beleuchtet die Details von Leitungsrohrsystemen nach IEC 61386 und vergleicht PVC-Rohre mit herk\u00f6mmlichen Metallrohren.

IEC- und IEC 61386-Standard verstehen<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h4><span class=\"ez-toc-section\" id=\"21_What_is_the_IEC\"><\/span>2.1 Was ist die IEC?<span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p>Die Internationale Elektrotechnische Kommission (IEC) ist eine globale Normungsorganisation, die internationale Normen f\u00fcr alle elektrischen, elektronischen und verwandten Technologien erarbeitet und ver\u00f6ffentlicht. Die 1906 gegr\u00fcndete IEC spielt eine entscheidende Rolle f\u00fcr die Sicherheit, Qualit\u00e4t und Interoperabilit\u00e4t elektrischer Produkte und Systeme weltweit. Ihre Normen werden von Regierungen, Herstellern und Aufsichtsbeh\u00f6rden weitgehend \u00fcbernommen und anerkannt und f\u00f6rdern die internationale Einheitlichkeit bei Design, Produktion und Leistung elektrischer Produkte.<\/p>\n<p>Die IEC spielt mit ihren vielf\u00e4ltigen Normen eine f\u00fchrende Rolle bei der Entwicklung von Kriterien f\u00fcr Systeme wie Kabelkan\u00e4le, Installationszubeh\u00f6r und elektrische Kabel. Die Organisation arbeitet eng mit nationalen Normungsinstitutionen zusammen, um die weltweite Umsetzung der IEC-Normen zu gew\u00e4hrleisten und so ein hohes Ma\u00df an Betriebssicherheit und technischer Kompatibilit\u00e4t in der Industrie zu erreichen.<\/p>\n<h4><span class=\"ez-toc-section\" id=\"22_What_is_IEC_61386_Standard\"><\/span>2.2 Was ist die Norm IEC 61386?<span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p>Unter den wichtigsten Normen gilt IEC 61386 weithin als die ma\u00dfgebliche Referenz f\u00fcr Rohrsysteme, die sich speziell auf die Klassifizierung und die Leistungsanforderungen von Rohrsystemen konzentriert, die zum Schutz und zur Verlegung elektrischer Leitungen verwendet werden.<\/p>\n<p><strong>2.2.1 L\u00e4nder und M\u00e4rkte, die IEC 61386 anwenden<\/strong><\/p>\n<p><strong>China<\/strong><\/p>\n<p>China hat die Norm IEC 61386 in die nationale Norm GB\/T 20041.1-2015 \u00fcbersetzt, die f\u00fcr Leitungsrohrsysteme auf dem heimischen Markt gilt. Diese Anpassung gew\u00e4hrleistet, dass lokale Hersteller und Fachleute international anerkannte Sicherheits- und Leistungsstandards f\u00fcr Leitungsrohrsysteme einhalten und gleichzeitig den Anforderungen des globalen Marktes entsprechen.<\/p>\n<p><strong>Europ\u00e4ische Union (EU)<\/strong><\/p>\n<p>In der Europ\u00e4ischen Union wenden L\u00e4nder wie Deutschland, Frankreich und andere die Norm IEC 61386 durch die CE-Kennzeichnung weitgehend an. Dies gew\u00e4hrleistet, dass Leitungssysteme die grundlegenden europ\u00e4ischen Sicherheits- und Leistungsstandards erf\u00fcllen und erleichtert den freien Warenverkehr innerhalb der EU. Die Anerkennung der IEC 61386 in der EU hilft Herstellern und Lieferanten sicherzustellen, dass ihre Leitungssysteme die strengen Marktanforderungen erf\u00fcllen.<\/p>\n<p><strong>Andere IEC-Mitgliedsl\u00e4nder<\/strong><\/p>\n<p>Australien, Japan und diverse andere IEC-Mitgliedstaaten nutzen IEC 61386 h\u00e4ufig als Grundlage f\u00fcr ihre nationalen technischen Vorschriften oder Branchenspezifikationen. Diese L\u00e4nder passen die IEC-Norm zwar mitunter an lokale Gegebenheiten an, die Kernprinzipien der IEC 61386 bleiben jedoch Basis ihrer technischen Anforderungen. Die weite Verbreitung von IEC 61386 tr\u00e4gt zur Standardisierung von Leitungssystemen bei und gew\u00e4hrleistet Sicherheit, Qualit\u00e4t und Kompatibilit\u00e4t \u00fcber L\u00e4ndergrenzen hinweg.<\/p>\n<p><strong>2.2.2 Welche Leitungstypen werden in der Norm IEC 61386 erw\u00e4hnt?<\/strong><\/p>\n<p><strong>Metallische Leitungen<\/strong> \u2013 Bekannt f\u00fcr ihre hohe mechanische Festigkeit und Erdungseigenschaften.<\/p>\n<p><strong>Nichtmetallische Leitungen<\/strong> \u2013 Hergestellt aus Materialien wie PVC, die Korrosionsbest\u00e4ndigkeit und elektrische Isolierung bieten.<\/p>\n<p><strong>Verbundleitungen<\/strong> \u2013 Kombination der Eigenschaften metallischer und nichtmetallischer Werkstoffe f\u00fcr spezielle Anwendungen.<\/p>\n<p>Die Norm beschreibt die Leistungsanforderungen unter normalen und extremen Bedingungen, einschlie\u00dflich der Einwirkung von mechanischem Druck, thermischer Belastung und Chemikalien. Sie definiert au\u00dferdem die Pr\u00fcfmethoden zur Bewertung der Einhaltung dieser Leistungskriterien.<\/p>\n<p>Dar\u00fcber hinaus erkennt die IEC 61386 an, dass bestimmte Leitungssysteme f\u00fcr den Einsatz in explosionsgef\u00e4hrdeten Bereichen geeignet sein k\u00f6nnen. In solchen F\u00e4llen m\u00fcssen zus\u00e4tzliche Anforderungen erf\u00fcllt werden, um Sicherheit und Konformit\u00e4t zu gew\u00e4hrleisten.<\/p>\n<p><strong>2.2.3 Klassifizierung von Leitungen gem\u00e4\u00df IEC 61386<\/strong><\/p>\n<p>Die IEC 61386 ist in mehrere Teile gegliedert, die jeweils spezifische Arten von Leitungssystemen und deren besondere Anforderungen behandeln:<\/p>\n<p><strong>IEC 61386-21<\/strong> \u2013 Starre Leitungssysteme: Definiert die Anforderungen an Leitungen, die unter mechanischer Belastung ihre feste Form beibehalten.<\/p>\n<p><strong>IEC 61386-22<\/strong> \u2013 Biegsame Leitungssysteme: Umfasst Leitungen, die gebogen oder gelenkig bewegt werden k\u00f6nnen, ohne in ihre urspr\u00fcngliche Form zur\u00fcckzukehren.<\/p>\n<p><strong>IEC 61386-23<\/strong> \u2013 Flexible Leitungssysteme: Spezifiziert die Eigenschaften von Leitungen, die sich wiederholt biegen und biegen lassen, ohne Schaden zu nehmen.<\/p>\n<p><strong>IEC 61386-24<\/strong> \u2013 Unterirdisch verlegte Leitungssysteme: Beschreibt die besonderen Anforderungen an Leitungen, die dem Erddruck, der Feuchtigkeit und Temperaturschwankungen ausgesetzt sind.<\/p>\n<p><strong>IEC 61386-25<\/strong> \u2013 Befestigungselemente f\u00fcr Leitungsrohre: Definiert die Leistungsanforderungen an Komponenten, die zur Befestigung von Leitungsrohrsystemen verwendet werden.<\/p>\n<p>Dieses Klassifizierungssystem erm\u00f6glicht es Herstellern, Installateuren und Pr\u00fcfern, das geeignete Leitungssystem f\u00fcr spezifische Anwendungen auszuw\u00e4hlen und so Konsistenz und die Einhaltung internationaler Sicherheits- und Leistungsstandards zu gew\u00e4hrleisten.<\/p>\n<p>Hier stellen wir Ihnen einige Details zur IEC und zum IEC 61386-Standard vor.<\/p>\n<p>Im folgenden Abschnitt werden wir uns genauer mit IEC 61386-1 befassen, einem wichtigen Bestandteil der Normenreihe IEC 61386, in der die allgemeinen Anforderungen an Leitungssysteme festgelegt sind.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"3_Introduce_Key_Requirements_in_IEC_61386_Standard\"><\/span>3.

The conduit passes if it does not exhibit visible flames or sustained glowing, or if any flames extinguish within 30 seconds after wire removal.<\/p>\n<p>The second test applies a 1 kW flame, in accordance with IEC 60695-11-2. The conduit sample is placed vertically inside a metal enclosure with an open face to minimize external air interference. This test further evaluates the flame resistance of non-metallic and composite conduits under direct fire exposure.<\/p>\n<p><strong>4.4.3\u00a0 Spread of Fire<\/strong><\/p>\n<p>To ensure fire resistance, conduits are tested by direct flame exposure at a 45\u00b0 angle within a controlled metal enclosure.
