Systems for renovation of drains and sewers - Lining with a rigidly anchored plastics inner layer (RAPL)
This European Standard specifies performance requirements and describes test methods for pipes and fittings for the renovation of underground drain and sewer systems by lining with a single rigid annulus of structural cementitious grout formed behind a plastics inner layer. This plastics layer serves as permanent formwork anchored to the grout. It is applicable to plastics inner layers and grout systems with or without steel reinforcement.
This European Standard does not apply to the structural design of the lining system.
NOTE Systems with multiple annuli are available, but these are controlled by patent rights and not covered by this European Standard.
Systeme für die Renovierung von Abwasserkanälen und -leitungen - Lining mit fest verankerter Kunststoffauskleidung
Diese Europäische Norm legt Anforderungen und Prüfverfahren für Rohre und Formstücke fest, die für die Renovierung von erdverlegten Abwasserkanälen und -leitungen durch Lining mit einem biegesteifen Ringraum aus statisch tragender Zementmörtelverfüllung, der hinter einer Kunststoffauskleidung geformt wird, verwendet werden. Die mit dem Mörtel verankerte Kunststoffauskleidung dient als dauerhafte Verschalung. Sie gilt für Kunststoffauskleidungen und Mörtel-Systeme mit oder ohne Stahlbewehrung.
Diese Europäische Norm gilt nicht für die statische Bemessung des Lining Systems.
ANMERKUNG Systeme mit mehreren Ringräumen sind verfügbar, jedoch durch Patente geschützt und deshalb nicht im Anwendungsbereich der vorliegenden Europäischen Norm enthalten.
Systèmes de rénovation des réseaux d'assainissement - Chemisage par revêtement de plastique interne rigidement ancré
La présente Norme européenne spécifie les exigences de performance et décrit les méthodes d’essai des tuyaux et raccords pour la rénovation des systèmes de branchements et de collecteurs enterrés par chemisage avec un seul espace annulaire rigide injecté de coulis structurel à base de ciment formé derrière un revêtement de plastique interne. Ce revêtement de plastique sert essentiellement de coffrage permanent ancré dans le coulis. La présente Norme européenne s'applique aux revêtements internes de plastique et aux systèmes de coulis avec ou sans renforcement en acier.
La présente Norme européenne ne s'applique pas au dimensionnement structurel du système de chemisage.
NOTE Des systèmes avec plusieurs espaces annulaires sont disponibles, mais ils font l’objet de droits de propriété intellectuelle ou de droits analogues et ne sont pas couverts par la présente Norme européenne.
Sistemi za obnovo odvodov odpadne vode in kanalizacije - Oblaganje s togo pritrjeno polimerno notranjo oblogo (RAPL)
Ta evropski standard določa zahteve glede zmogljivosti in opisuje preskusne metode za cevi ter spojnike za obnovo odvodov odpadne vode in kanalizacije z oblaganjem z enim togo pritrjenim vmesnim prostorom strukturne cementne injekcijske mase za polimerno notranjo oblogo. Ta polimerna obloga služi kot stalen opaž, ki je pritrjen na maso. Uporablja se za polimerne notranje obloge in sisteme za nanašanje malte z jekleno armaturo ali brez nje.
Ta evropski standard se ne uporablja za projektiranje konstrukcij sistema oblog.
OPOMBA: Sistemi z več vmesnimi prostori so na voljo, vendar so nadzorovani s patentnimi pravicami in niso vključeni v tem evropskem standardu.

EN 16506:2014 (E) 4 Foreword This document (EN 16506:2014) has been prepared by Technical Committee CEN/TC 165 “Wastewater engineering”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by April 2015 and conflicting national standards shall be withdrawn at the latest by April 2015. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. Products conforming to this standard do not belong to the product family “Plastics piping systems for renovation of underground non-pressure drainage and sewerage networks”, because the structural behaviour depends mainly on the cementitious grout and the plastics inner layer serves primarily as permanent formwork for corrosion protection. For the technique of spirally wound pipes in particular the scope of EN ISO 11296-7 is distinguished from that of this standard in requiring the plastics pipe component to have adequate ring stiffness to resist all external loads on its own without any structural contribution from grout used as annular filler as given in EN 15885:2010, 5.7. Plastic piping systems used for renovation are specified in the standards series EN ISO 11296, comprising a “Part 1: General” and various technique related parts. This document follows the approach in considering products used for renovation at the “M” stage and the “I” stage as specified in EN 13380 and the series EN ISO 11296. According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.
