District heating pipes - Preinsulated bonded pipe systems for directly buried hot water networks - Surveillance systems
This European Standard specifies basic functional requirements for surveillance systems for district heating pipe systems, specific requirements for measuring elements and their installation within preinsulated bonded pipes, valves and fittings, and the field assembly of these measuring elements in pipe joints.
This standard specifies requirements for the manufacture of measuring elements, for the manufacture of preinsulated bonded pipe elements with measuring elements and for the assembly of the measuring elements in the field.
All requirements and recommendations described in this standard are based on the experience gained with existing surveillance systems and their principal function, cf. Annex A.
The specific requirements given are only valid for electrical wire based surveillance systems forming an integral part of the pipes, valves, fittings and joints.
Fernwärmerohre - Werkmäßig gedämmte Verbundmantelrohrsysteme für erdverlegte Fernwärmenetze - Überwachungssysteme
Diese Europäische Norm legt die grundlegenden Funktionsanforderungen an Überwachungssysteme für Fernwärme-Rohrleitungssysteme, besondere Anforderungen an Messelemente und an deren Einbau in werk¬mäßig gedämmte Verbundmantelrohre, Absperrarmaturen und Formstücke sowie an die Montage der Mess¬elemente in Rohrverbindungen vor Ort fest.
Diese Norm legt die Anforderungen zur Herstellung von Messelementen, zur Herstellung von werkmäßig ge¬dämmten Verbundmantelrohrelementen mit Messelementen und die Montage der Messelemente vor Ort fest.
Alle in dieser Norm beschriebenen Anforderungen und Empfehlungen basieren auf der Erfahrung mit beste¬henden Überwachungssystemen und deren prinzipiellen Funktionsweisen; siehe Anhang A.
Die angegebenen speziellen Anforderungen gelten nur für Überwachungssysteme mit elektrischen Leitern, die einen integralen Bestandteil der Rohre, Absperrarmaturen, Formstücke und Verbindungen darstellen.
Tuyaux de chauffage urbain - Systèmes bloqués de tuyaux préisolés pour les réseaux d'eau chaude enterrés directement - Systèmes de surveillance
La présente Norme européenne spécifie les exigences fonctionnelles de base concernant les systèmes de
surveillance destinés aux systèmes de tuyaux pour le chauffage urbain, les exigences spécifiques relatives
aux éléments de mesure et à leur installation dans des tuyaux, robinets et raccords bloqués pré-isolés, de
même que les exigences concernant l’assemblage sur site de ces éléments de mesure dans les
assemblages de tubes.
La présente norme précise les exigences relatives à la fabrication des éléments de mesure, à la fabrication
des éléments de tuyau bloqués pré-isolés avec les éléments de mesure et à l’assemblage sur site desdits
éléments de mesure.
Toutes les exigences et recommandations décrites dans la présente norme sont fondées sur l’expérience
acquise avec les systèmes de surveillance existants et leur fonction principale, voir l’Annexe A.
Les exigences spécifiques indiquées sont valides uniquement pour les systèmes de surveillance électriques
formant partie intégrante des tubes, robinets, raccords et autres assemblages.
