This European Standard shall be given the status of a national standard,
12、either by publication of an identical text or by endorsement, at the latest by January 2015 and conflicting national standards shall be withdrawn at the latest by January 2015. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN a
13、nd/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 13523-4:2001. The main technical changes are: a) the definition of pencil hardness was amended; b) the term “remove the coating” was corrected to “scratch the coating” in the descri
14、ption of the result of the test; c) a remark on preconditioning was added; d) concerning the applicability of the pencil hardness test, a reference to EN ISO 15184 was added.

21、e This part of EN 13523 describes the procedure to assess the relative hardness of an organic coating on a metallic substrate, by means of pencils of known hardness. Smooth surfaces will give more accurate results but the method is also applicable for textured surfaces. The more pronounced the textu
22、re, the greater the unreliability of results. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
