DESCRIPTION
BS EN ISO 15184:2020 - TC
This standard BS EN ISO 15184:2020 - TC Tracked Changes. Paints and varnishes. Determination of film hardness by pencil test is classified in these ICS categories:
- 87.040 Paints and varnishes
This document specifies a method for determining the film hardness by pushing 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 multi-coat system.
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.
The method is applicable only to smooth surfaces.
