Ductile iron pipes, fittings and accessories - External polyurethane coating for pipes - Requirements and test methods
This European standard defines the requirements and test methods applicable to factory applied external polyurethane based coatings for heavy duty (Annex D.3 of EN 545:2002) corrosion protection of buried ductile iron pipes conforming to EN 545, EN 598 and EN 969 for use at operating temperatures up to 50 °C.
This standard does not cover ductile iron pipes protected with zinc with a finishing layer of polyurethane.
This standard does not cover special activities on site such as tapping, clamping, etc., which could affect the corrosion protection properties of the polyurethane coating. These operations should be covered in the laying instructions supplied by manufacturers of clamps, house connection saddles, etc. and any relevant user procedures.
Rohre, Formstücke und Zubehör aus duktilem Gusseisen - Polyurethanumhüllung von Rohren - Anforderungen und Prüfverfahren
Diese Europäische Norm legt die Anforderungen und Prüfverfahren für werksseitig aufgebrachte Umhüllungen
auf Polyurethanbasis für den Korrosionsschutz bei starker Beanspruchung (Anhang D.3 in EN 545:2002) von
erdverlegten Rohren aus duktilem Gusseisen nach EN 545, EN 598 und EN 969 für den Einsatz bei Betriebs-temperaturen
bis 50 °C fest.
Diese Norm gilt nicht für Rohre aus duktilem Gusseisen, die mit Zink und einer Deckbeschichtung aus Poly-urethan
geschützt sind.
Bestimmte Arbeiten vor Ort, z. B. Anbohren, Herstellen von Klemmverbindungen usw., können die Korro-sionsschutzeigenschaften
der Polyurethanumhüllung beeinträchtigen. Diese Arbeitsvorgänge sollten in den
vom Hersteller der Klemmverbinder, Anbohrsättel, usw. mitgelieferten Einbauanleitungen sowie für alle dies-bezüglichen
Arbeiten des Betreibers festgelegt sein.
Tuyaux, raccords et accessoires en fonte ductile - Revêtement extérieur polyuréthanne des tuyaux - Exigences et méthodes d'essai
La présente Norme européenne définit les exigences et méthodes d'essai applicables aux revêtements extérieurs à base de polyuréthanne appliqués en usine, destinés à assurer une protection renforcée contre la corrosion (Annexe D.3 de l'EN 545:2002) des tuyaux en fonte ductile enterrés conformes à l'EN 545, l'EN 598 et l'EN 969, prévus pour des températures de service inférieures ou égales à 50 °C.
La présente norme ne traite pas des tuyaux en fonte ductile protégés par du zinc et par une couche de finition polyuréthanne. Des activités particulières sur site (martèlement léger, fixations par serrage, etc.) sont susceptibles d'influer sur les propriétés de protection contre la corrosion du revêtement polyuréthanne. Il convient que ces opérations soient mentionnées dans les instructions de pose fournies par les fabricants de fixations par serrage, de sellettes de raccordement, etc., ainsi que dans le mode opératoire approprié de l'utilisateur. Ces instructions ne font pas partie de la présente norme.

Ductile iron pipes according to EN 545, EN 598 or EN 969, but externally coated in accordance with this European Standard shall be specified in the purchaser enquiry and order by reference to this standard. EXAMPLE: 5 000 m of ductile iron pipe DN 300 according to EN 545; external polyurethane coating according to EN 15189. The manufacturer shall obtain from the purchaser the type of coating to be used for pipe ends (see 5.3). 5 Technical Requirements 5.1 Surface preparation Prior to application of the polyurethane coating, the surface of the pipes shall be technically clean, free of rust, loose constituent materials, dirt, oil, grease and moisture. In cold weather, or anytime when moisture tends to condense on the surface of the pipe, the pipe shall be uniformly warmed for a sufficient time to dry the pipe prior to cleaning. The pipe temperature shall be maintained at at least 5 °C above the dew point. The surface shall be prepared by grit blasting and be in compliance with level Sa 2.5 of EN ISO 8501-1. The surface roughness Ra, in accordance with EN ISO 8503-1, shall be at least 10 micrometers which is equivalent to an anchored profile, Rz of 50 micrometers or higher if required by the coating material provider or manufacturer. 5.2 Finished polyurethane coating 5.2.1 Appearance and continuity The polyurethane coating shall be: uniform in colour, except the spigot and the socket which may be of a different colour for permitted marking; uniform appearance and smoothness except for admissible repairs; free of visible defects (pinholes, bubbles, blisters, wrinkles, cracks or voids). Slight superficial variations of colour or brilliance, due to repairs or prolonged exposure to sunlight or contact with other pipes are permissible. SIST EN 15189:2007
5.7 Hardness When assessed by testing in accordance to EN ISO 868 the hardness of the polyurethane coating shall be at a minimum 70 Shore D. 5.8 Adhesion Adhesion shall be at least 8 MPa when tested in accordance with 7.1.9. 6 Performance Requirements 6.1 Chemical resistance The chemical resistance is determined by the change in weight of the polyurethane coating. When tested in accordance to 7.2.1, the weight increase and weight loss shall meet the requirements given in Table 1 when compared to the original weight. SIST EN 15189:2007
