Rohre, Formstücke und Zubehör aus duktilem Gusseisen - Zementmörtelumhüllung von Rohren - Anforderungen und Prüfverfahren

Diese Europäische Norm legt die Anforderungen und Prüfverfahren fest für werkseitig aufgebrachte Zementmörtelumhüllungen für den äußeren Korrosionsschutz von Rohren aus duktilem Gusseisen nach EN 545, EN 598 und EN 969 für die Verwendung bei Betriebstemperaturen bis 50 °C und einer Bodenbeschaffenheit nach EN 545:2002, D.3.
Spezielle vor Ort durchgeführte Maßnahmen, wie z. B. Schutz der Verbindungen, Anbohren, Herstellen von Klemmverbindungen, usw. können die Korrosionsschutzeigenschaften der Zementmörtelumhüllung beeinflussen. Diese Arbeiten sollten in den Einbauanleitungen der Hersteller von Rohren, Klemmelementen, Hausanschlussstücken, usw. und allen einschlägigen Arbeitsanleitungen für den Anwender angegeben sein. Diese Anleitungen sind nicht Teil dieser Europäischen Norm.

Tuyaux, raccords et accessoires en fonte ductile - Revetement extérieur en mortier de ciment pour tuyaux - Prescriptions et méthodes d'essai

La présente Norme européenne établit les prescriptions et les méthodes d’essai applicables aux revêtements en mortier de ciment appliqués en usine pour protéger de la corrosion extérieure les tuyaux en fonte ductile conformes aux EN 545, EN 598 et EN 969 et destinés à être utilisés à des températures de service allant jusqu’à 50 °C, et pour des conditions de sol conformes à l’Annexe D.2 de l’EN 545:2006.
Des activités particulières effectuées sur le site telles que la protection des joints, le taraudage, le bridage etc. peuvent avoir une incidence sur les propriétés de protection contre la corrosion du revêtement en mortier de ciment. Il convient de faire figurer ces opérations dans les instructions relatives à la pose fournies par les fabricants de tuyaux, brides et piquages à selle pour branchements domestiques etc. ainsi que dans les procédures pertinentes des utilisateurs.

EN 15542:2008 (E) 5 Introduction This European Standard is in conformity with the general requirements already established by CEN/TC 164 in the field of water supply (e.g. potable water) and CEN/TC 165 in the field of waste water. In respect of potential adverse effects on the quality of water intended for human consumption, caused by the product covered by this European Standard: a) this European Standard provides no information as to whether the product may be used without restriction in any of the member states of the EU or EFTA; b) it should be noted that, while awaiting the adoption of verifiable European criteria, existing national regulations concerning the use and/or the characteristics of this product remain in force. SIST EN 15542:2008

EN 15542:2008 (E) 6 1 Scope This European Standard defines the requirements and test methods applicable to factory applied cement mortar coatings for the external corrosion protection of ductile iron pipes conforming to EN 545, EN 598 and EN 969 for use at operating temperatures up to 50 °C, and for soil conditions according to Annex D.2 of EN 545:2006. Special activities on site such as joint protection, tapping, clamping, etc. could affect the corrosion protection properties of the cement mortar coating. These operations should be covered in the laying instructions supplied by the manufacturers of pipes, clamps, house connection saddles, etc. and any relevant users' procedures. Such instructions are not part of this European Standard. 2 Normative references The following referenced documents are indispensable for the application of this document.
