District heating pipes - Factory made flexible pipe systems - Part 1: Classification, general requirements and test methods

This document specifies classification, general requirements and test methods for flexible, factory made, buried district heating pipe systems.
This document is intended to be used in conjunction with part 2, 3 or 4, as applicable.
Depending on the pipe assembly (see Table 4), this document is applicable to a maximum operating temperature of 95 °C (part 2 and 3) and a maximum operating temperature of 120 °C (for part 4) and design pressures of 0,6 MPa to 2,5 MPa.
The pipe systems are designed for a service life of at least 30 years. For pipe systems with plastic service pipes, the respective temperature profiles are specified in EN 15632-2 and EN 15632-3.
NOTE   For the transport of other liquids, for example potable water, additional requirements can be applicable.

ANMERKUNG   Für den Transport von anderen Flüssigkeiten, wie z. B. Trinkwasser, können zusätzliche Anforderungen gelten.

Tuyaux de chauffage urbain - Systèmes de tuyaux flexibles manufacturés - Partie 1 : Classification, exigences générales et méthodes d'essai

Le présent document spécifie la classification, les exigences générales et les méthodes d’essai pour les systèmes de réseaux de tuyaux de chauffage urbain flexibles, manufacturés, enterrés directement.
Le présent document est prévu pour être utilisé conjointement avec les parties 2, 3 ou 4, si applicable.
En fonction de l'assemblage de tuyaux (voir Tableau 4), le présent document est applicable pour une température maximale de fonctionnement de 95 °C (parties 2 et 3) et une température maximale de fonctionnement de 120 °C (pour la partie 4) et des pressions de conception de 0,6 MPa à 2,5 MPa.
Les systèmes de tuyaux sont conçus pour une durée de vie prévue d’au moins 30 ans. Pour les systèmes de tuyaux avec des tubes de service en plastique, les profils de température respectifs sont précisés dans l’EN 15632-2 et l’EN 15632-3.
NOTE   Pour le transport d’autres liquides, par exemple de l’eau potable, des prescriptions supplémentaires peuvent s’appliquer.

Cevi za daljinsko ogrevanje - Tovarniško izdelani gibki cevni sistemi - 1. del: Klasifikacija, splošne zahteve in preskusne metode

Ta dokument določa klasifikacijo, splošne zahteve in preskusne metode za tovarniško izdelane gibke podzemne cevne sisteme za daljinsko ogrevanje.
Ta dokument je namenjen za uporabo skupaj z 2., 3. ali 4. delom (kot je ustrezno).
Glede na cevni sestav (glej tabelo 4) se ta dokument uporablja za najvišjo temperaturo medijev 95 °C (2. in 3. del) ter za najvišjo temperaturo medijev 120 °C (za 4. del) ter za konstrukcijske tlake od 0,6 MPa do 2,5 MPa.
Predvidena življenjska doba cevnih sistemov je najmanj 30 let. Temperaturni razponi za cevne sisteme z delovnimi cevmi iz polimernih materialov so določeni v standardih EN 15632-2 in EN 15632-3.
OPOMBA:   Za prevoz drugih tekočin, na primer pitne vode, morda veljajo dodatne zahteve.
