Ductile iron pipes, fittings and accessories - External cement mortar coating for pipes - Requirements and test methods

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.3 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.

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.2.
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 - Revêtement extérieur en mortier de ciment pour tuyaux - Prescriptions et méthodes d'essais

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. Ces instructions ne font pas partie intégrante de la présente norme.

Overview

EN 15542:2008 (CEN) specifies requirements and test methods for factory-applied external cement mortar coatings used as corrosion protection for ductile iron pipes, fittings and accessories. It applies to ductile iron products manufactured to EN 545, EN 598 and EN 969 for use at operating temperatures up to 50 °C and for soil conditions referenced in Annex D.3 of EN 545:2006. The standard covers the multi-layer coating system (zinc thermal spray + primer where used + cement mortar layer), inspection, routine and performance tests, and related quality assurance provisions.

Key Topics and Technical Requirements

• Coating system: Defined as a zinc coating (thermal spray) plus a cement mortar layer; polymer additives, primers, pigments, surface tissue or top coatings are permitted depending on manufacturer process.
• Zinc coating: Minimum mean mass of zinc ≥ 200 g/m²; zinc purity at least 99.99 %; zinc surface must be dry and clean.
• Primer: Where used, primer film thickness is specified (mean thickness between 80 µm and 150 µm when measured by approved methods).
• Cement mortar: Fresh mortar composition requirements and sampling are defined; mortar may be fibre-reinforced, polymer-modified and pigmented for identification.
• Mechanical performance: Requirements and test methods for bond strength (pull-off), impact resistance, and minimum/nominal coating thickness on cured mortar.
• Appearance and repairs: Visual and continuity requirements for cured coating; procedures for site repair and marking are described (site activities such as tapping, clamping, joint protection can affect coating and should be covered by laying instructions supplied by manufacturers).
• Testing regime: Differentiates routine tests (ongoing production control) and performance tests (initial qualification and after significant changes). Annexes cover quality assurance, application process guidance, sampling and constituent analysis.

Applications and Users

EN 15542 is intended for:

• Manufacturers of ductile iron pipes, fittings and accessories who apply factory external cement mortar coatings.
• Coating applicators and subcontractors responsible for surface preparation and thermal spray application.
• Water, wastewater and gas utilities specifying corrosion protection for buried pipelines.
• Design engineers, procurement officers and QA laboratories verifying compliance with coating, thickness, bond and impact tests.
• Specifiers preparing tender documents for pipeline systems requiring durable external corrosion protection.
