ISO/FDIS 15184
Abstract
This standard specifies a method for determining the film hardness by pushing or pulling up pencils of known hardness over the film.
The test can be performed on a single coating of a paint, varnish or related product, or on the upper layer of a multicoat system.
This rapid, inexpensive 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.
The method is applicable only to smooth surfaces.
