This part of EN 14483 describes a test method for the determination of resistance to attack in closed systems by acid and neutral liquids, as well as by actual process mixes, the given corrosive agent generally applied at a temperature above its boiling point. It is also applicable to the determination of resistance to mildly alkaline fluids provided that the material of the test equipment is suitable for such a test (see also 4.1.2).This European Standard primarily applies to the testing of enamels designed for use in chemical process technology.
