30、pecifies a test method for the determination of the scratch resistance of enamelfinishes. The method is based on ISO 1518:1992, Paints and varnishes Scratch test, but is performed atsignificantly higher forces.The value of the scratch resistance that is obtained is a measure of the durability of por

31、celain enamel finishes whenscratched by sharp objects under high forces. The value should not be confused with scratch hardness, a quantitythat is measured by the procedure described in EN 101:1991, Ceramic tiles Determination of scratch hardnessof surface according to Mohs.2 Normative referencesThe

32、 following normative documents contain provisions which, through reference in this text, constitute provisions ofthis International Standard. For dated references, subsequent amendments to, or revisions of, any of thesepublications do not apply. However, parties to agreements based on this Internati
