JANKA RATINGS

The Janka hardness test measures the force necessary to embed an 11.28mm (.444) steel ball into a wood sample half the ball’s diameter.  The common use of this scale is to determine if a species is suitable for flooring and the depth of the indention.
It should be noted the tests are not conducted on actual flooring, and the types of wear layer and construction of the floor also contribute to its dent resistance. Please keep in mind that no hardwood flooring is dent or scratch proof.
