EN 13523-6:2002 (E)2ForewordThis document EN 13523-6:2002 has been prepared by Technical Committee CEN/TC 139 "Paints and varnishes",the secretariat 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of an identical text orby endorsement, at the latest by January 2003, and conflicting national standards shall be withdrawn at the latestby January 2003.According to the CEN/CENELEC Internal Regulations, the national standards organizations of the followingcountries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain,Sweden, Switzerland and the United Kingdom.1 ScopeThis Part of EN 13523 defines terms of the procedure for determining the adhesion of an organic coating to ametallic substrate after indentation after slow deformation.The resistance to cracking can also be evaluated.2 Normative referencesThis European Standard incorporates, by dated or undated reference, provisions from other publications. Thesenormative references are cited at the appropriate places in the text, and the publications are listed hereafter. Fordated references, subsequent amendments to or revisions of any of these publications apply to this EuropeanStandard only when incorporated in it by amendment or revision. For undated references the latest edition of thepublication referred to applies (including amendments).EN 13523-0:2001, Coil coated metals - Test methods - Part 0: General introduction and list of test methods.EN 23270:1991, Paints and varnishes and their raw materials - Temperatures and humidities for conditioning andtesting (ISO 3270:1984).EN ISO 1520:2001, Paints and varnishes - Cupping test (ISO 1520:1999).IEC 60454-2:1994, Specification for pressure-sensitive adhesive tapes for electrical purposes - Part 2: Methods oftest.3 Terms and definitionsFor the purposes of this Part of EN 13523, the terms and definitions given in EN 13523-0:2001 apply.4 PrincipleThe test specimen is cross-hatched with a cutting tool and is then deformed by pressing under specified conditions.After pressing, the test specimen can be artificially aged by immersion in boiling water.SIST EN 13523-6:2003



EN 13523-6:2002 (E)35 Apparatus and materials5.1
Cross-hatching deviceA single-bladed knife, very sharp to avoid any burrs. For coatings less than 60 µm in thickness, it is also possible touse a purpose-made cutting tool, capable of making a minimum of 6 parallel cuts.5.2
Pressing deviceApparatus in accordance with EN ISO 1520:2001, consisting essentially of:a) a steel die, of inside diameter (27 ± 0,05) mm, its contact surface with the test specimen being flat andpolished;b) a retainer ring, having its flat and polished surface in contact with the test specimen;c) a striker consisting of a polished steel sphere, of diameter (20 ± 0,05) mm with a maximum of 0,1 mmdisplacement from the axis of the die;d) a system, preferably hydraulic, allowing movement of the striker at a speed of (12 ± 6) mm/min.5.3
Ageing deviceThe ageing device shall consist of:a) a vessel, to contain boiling water, whose dimensions allow the complete immersion of the test specimen;b) a heating system.5.4
Pincers, the jaws of which shall be flat, blunt and having a width of at least 5 mm.5.5
Magnifying glass ´10.5.6
