<p>ISO 15184:2012 specifies a method for determining the film hardness by pushing pencils of known hardness over the film.</p>
<p>The test can be performed on a single coating of a paint, varnish or related product, or on the upper layer of a multi-coat system.</p>
<p>This rapid test has not been found to be useful in comparing the pencil hardness of different coatings. It is more useful in providing relative ratings for a series of coated panels exhibiting significant differences in pencil hardness.</p>
<p>The method is applicable only to smooth surfaces.</p>
