<P>ISO 12137-1:2010 specifies a method for determining, using a curved (loop-shaped or ring-shaped) stylus, the scratch resistance of a single coating of a paint, varnish or related product, or the upper layer of a multicoat system.</P>
<P>This test has been found to be useful in comparing the scratch resistance of different coatings. It is most useful in providing relative ratings for a series of coated panels exhibiting significant differences in scratch resistance.</P>
<P>ISO 12137-1:2010 does not specify a method using a pointed stylus, which is specified in ISO 12137-2. The choice between the two methods will depend on the particular practical problem.</P>
