26、 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of an identical text or by endorsement, at the latest by June 2007, and conflicting national standards shall be withdrawn at the latest by June 2007. EN 14879 “Organic coating sys
27、tems and linings for protection of industrial apparatus and plants against corrosion caused by aggressive media“ consists of the following parts: Part 1: Terminology, design and preparation of substrate Part 2: Coatings on metallic components Part 3: Coatings on concrete components Part 4: Linings o
28、n metallic components Part 5: Linings on concrete components Part 6: Combined linings with tile and brick layers 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,
29、 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 14879-3:2006 (E) 6 1 Scope This European
30、Standard specifies the requirements for and methods of testing of organic coatings which are applied to concrete process engineering equipment that will come in contact with aggressive chemical substances (liquids, solids and gases). The requirements specified here may be used for the purposes of qu
31、ality control (e.g. as agreed between the contract partners). The standard does not cover coatings as in EN ISO 12944-1, but it does apply to coatings which serve one or more of the following purposes: to protect the component from damaging effects of aggressive substances; to protect waters (e.g. g
32、round water) from harmful substances; to protect the charge from becoming contaminated by components released from the substrate material; to achieve a particular surface properties. The different coating systems are: a) impregnation, seals, thin coatings (applied by brushing, spraying or rolling);
33、b) high-build coatings (applied by brushing, spraying, rolling, trowelling or pouring (self-levelling); c) laminate coatings; d) resinous screed; e) mastic asphalt screed with a waterproofing layer; f) combinations of the above coatings. Table 1 shows the coating methods to be employed for various t
34、ypes of concrete members. Handling of aggressive or water pollutant materials is understood to include: 1) storage; 2) filling; 3) loading and unloading; 4) manufacture; 5) treatment; 6) use.
