EN 14901:2006 (E) 3 Foreword This document (EN 14901:2006) has been prepared by Technical Committee CEN/TC 203 “Cast iron pipes, fittings and their joints”, the secretariat of which is held by AFNOR. 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of an identical text or by endorsement, at the latest by November 2006, and conflicting national standards shall be withdrawn at the latest by November 2006. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.



EN 14901:2006 (E) 4 Introduction This Standard is in conformity with the general requirements already established by CEN/TC 164 in the field of water supply (e.g. potable water), CEN/TC 165 in the field of wastewater and CEN/TC 234 in the field of gas distribution. In respect of potential adverse effects on the quality of water intended for human consumption, caused by the product covered by this Standard: 1) this 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; 2) 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.



EN 14901:2006 (E) 5 1 Scope This European Standard defines the requirements and test methods for factory applied epoxy coatings (fusion bonded powder or liquid two-pack) used for the corrosion protection of ductile iron fittings and accessories conforming to EN 545, EN 598, EN 969, EN 12842, EN 14525, for:  conveying water (e.g. potable water) at operating temperature up to 50 °C excluding frost; or  conveying waste water at operating temperature up to 45 °C excluding frost; or  conveying gas at operating temperature up to 50 °C;  suitable for external environments, i.e. soils, waters and atmospheres of all common corrosion loads, characterised in annex D3 of EN 545:2002. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 545:2002, Ductile iron pipes, fittings, accessories and their joints for water pipelines – Requirements and test methods. EN 598, Ductile iron pipes, fittings, accessories and their joints for sewerage application – Requirements and test methods. EN 805: Water supply – Requirements for systems and components outside buildings. EN 969, Ductile iron pipes, fittings accessories and their joints for gas pipelines – Requirements and test methods. EN 12842, Ductile iron fittings for PVC-U or PE piping systems – Requirements and test methods. EN 14525, Ductile iron wide tolerance couplings and flange adaptors for use with pipes of different materials: ductile iron, Grey iron, Steel, PVC-U PE, Fibre-cement. EN ISO 4624, Paints and varnishes – Pull off test for adhesion (ISO 4624:2002). EN ISO 8501-1, Preparation of steel substrates before application of paints and related products – Visual assessment of surface cleanliness – Part 1 : Rust grades and preparation grades of uncoated steel substrates and of steel substrates after overall removal of previous coatings (ISO 8501-1:1988). 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 accessory any casting other than a pipe or fitting which is used in a pipeline:  inspection chambers;  manholes;



EN 14901:2006 (E) 6  glands for mechanical flexible joints;  glands and locking rings for restrained flexible joints;  pipe saddles for house connection;  adjustable flanges. NOTE Valves of all types are not covered by the term accessory. 3.2 adhesion force per unit area, applied perpendicular to the surface, which is necessary to separate the coating from its substrate 3.3 cross linkage chemical reaction between epoxy resin and hardener to form the final coating 3.4 ductile iron cast iron used for pipes, fittings and accessories in which graphite is present substantially in spheroidal form 3.5 fitting casting other than a pipe or accessory which allows pipeline deviation, change of direction or bore. In addition flanged-socket pieces, flanged spigot pieces and collars are also classified as fittings 3.6 impact strength impact energy which a coating can withstand without damage under specific test conditions 3.7 indentation resistance resistance of the coating to the penetration of a punch under defined test conditions 3.8 non porosity absence of electrical puncture in a high voltage test under defined test conditions 3.9 epoxy coating factory applied coating with pure epoxy as a binder such as:  fusion bonded epoxy powder (P) applied by (electrostatic) spraying or dipping in fluidised bed on preheated parts;  two-pack liquid epoxy (L) consisting of a base and a catalyst component which is mixed together in the proportion specified by the manufacturer before use;  as binder only pure epoxy is allowed. 3.10 chalking superficial reaction of epoxy coatings influenced by UV-radiation. The process is stopped by the reaction products at a depth of 2 – 5 µm, combined with a loss of brilliance. There are no adverse influences on the protection properties



EN 14901:2006 (E) 7 3.11 performance test test which is done once and is repeated only after change of coating material supplier, coating material or relevant change in process application 3.12 routine test test carried out to control the manufacturing process with a frequency defined by the manufacturer of the coated ductile iron component 3.13 designated zones areas of a casting where because of jointing tolerance restrictions, testing difficulties, or shrouding by a gasket, etc. a lower standard of coating performance is unavoidable. For the purpose of this standard these areas are defined as:  joint areas;  bolt holes;  permitted markings;  ribs;  edges. NOTE Where considered necessary, these zones may be protected by appropriate additional corrosion protection measures during or after installation. However, such measures are not part of this standard. 3.14 average thickness arithmetic mean of all thickness measurements taken on one coated item 3.15 localised thickness measured thickness at any one point of one coated item 4 Ordering information
