Paints and varnishes. Determination of film hardness by pencil test Ingestion-build-52208What is ISO 15184 about? ISO 15184 discusses paints and varnishes. ISO 15184 specifies a method for determining the film hardness by pushing pencils of known hardness over the film. The rapid test in ISO 15184 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 in ISO 15184
