This document specifies the requirements and test methods for plastics piping systems used for renovation of underground gas supply networks. It is applicable to pipes and fittings as manufactured as well as to the installed lining system; it does not cover sprayed coatings, the existing pipeline or any annular filler.
Functional recommendations on this subject are covered by EN 12007 parts 1 and 4.
This part of EN 14408 deals with the general requirements common to all relevant renovation techniques as defined in 3.2.
Kunststoff-Rohrleitungssysteme für die Renovierung von erdverlegten Gasversorgungsnetzwerken - Teil 1: Allgemeines
Diese Norm legt die Anforderungen an und Prüfverfahren für Kunststoff-Rohrleitungssysteme fest, die für den Einsatz bei der Renovierung von erdverlegten Gasversorgungsnetzen verwendet werden. Sie umfasst Anforderungen an Rohre und Formstücke "wie hergestellt" und "wie eingebaut". Sie ist auf Kunststoff-Rohr-leitungssysteme anwendbar, die sowohl in Wechselwirkung stehende als auch unabhängige Druck-Liner-Rohre enthalten, sie umfasst keine Spritzbeschichtungen. Sie legt keine Anforderungen an die bestehende Rohrleitung oder an gegebenenfalls erforderliche Ringraumfüllstoffe fest.
Funktionale Anforderungen hinsichtlich der Renovierung des gesamten Systems und die entsprechenden Tätigkeiten werden von dieser Norm nicht abgedeckt. Siehe EN 12007, Teile 1 und 4.
Dieser Teil der von prEN 14408behandelt die allgemeinen Anforderungen, die für alle entsprechenden Lining-Ver-fahren nach 3.1.2 gelten.
Systèmes de canalisations plastiques pour la rénovation des réseaux de gaz enterrés - Partie 1 : Généralités
La présente norme spécifie les exigences et les méthodes d'essai pour les systèmes de canalisations utilisés pour la rénovation des réseaux de gaz enterrés. Elle est applicable aux tubes et raccords préfabriqués ou au système de rénovation une fois installé. Elle ne couvre pas les enduits projetés, la canalisation existante ou le matériau de remplissage annulaire.
Des recommandations fonctionnelles sur ce sujet sont données dans l'EN 12207 parties 1 et 4.
La présente partie de l'EN 14408 traite des exigences générales communes à toutes les techniques de rénovation pertinentes, telles que définies en 3.1.2.

These System Standards are distinguished from those for conventionally installed plastics piping systems by setting requirements for certain characteristics in the as-installed condition, after site processing. This is in addition to specifying requirements for system components as manufactured. Each of the System Standards comprises a: — Part 1:

Figure 2 Technique families for renovation of underground gas supply networks using plastics pipes within the scope of pipeline rehabilitation techniques. The technique families within the scope of this document are defined as follows: 3.2.1 lining with continuous pipes lining with pipe made continuous for the length of the section to be renovated prior to insertion, and which has not been shaped to give it a cross-sectional diameter smaller than its final diameter after installation SIST EN 14408-1:2005
reduction in the pipe manufacturing plant; the pipe is usually supplied coiled on a reel from which it is directly inserted; b)
reduction on site: the pipe is usually fed through the reduction equipment and simultaneously inserted in one continuous string. 3.2.3 lining with cured-in-place pipes
lining with a flexible tube impregnated with a thermosetting resin which produces a pipe after resin cure 3.3
