EN 14879-2:2006 (E) 6 1 Scope This European Standard specifies the requirements for and methods of testing of organic coatings which are applied to metallic process engineering equipment that will come in contact with che

31、mical substances (liquids, solids and gases). The requirements specified here may be used for the purposes of quality control (e.g. as agreed between the contract partners or been given by national regulations). The standard does not cover coatings as in EN ISO 12944-1, but it does apply to coatings

32、 which serve one or more of the following purposes: to protect the component from adverse effects of aggressive substances; to protect waters (e.g. ground water) against hazardous substances; to protect the charge from becoming contaminated by components released from the substrate material; to achi

33、eve a particular surface properties. The described coatings are to be used for metallic process engineering equipment that will come in contact with chemical substances. The different coating systems are: laminate coating systems which contain cold-curing resins; trowelled coating which contain cold

34、-curing resins; sprayed coating systems which contain resins (in special cases, such coatings may also be applied by brushing, rolling, flow coating, dipping, or by other means, such as providing sleeving for nozzles); powder coating systems which contain organic materials (powder coatings may be us

35、ed as corrosion pro-tection or for non-stick purposes).
