This document specifies a method for determining the resistance of a coating to scratches introduced by a usually hand-held loaded stylus.<\/p>\n

The test can be carried out using a point stylus (method A) or using a disc stylus (method B).<\/p>\n

Both methods are generally applicable and can be used in the field as well as on curved surfaces. Method A can also be applied on small test specimens (minimum dimensions 30 mm \u00d7 50 mm).<\/p>\n

The test can be carried out as a \u201cpass\/fail\u201d test (test requirement I) or as a classification test (test requirement II).<\/p>\n
