Janka Test Measures Hardness Of Wood

This test measures the resistance of various types of wood to denting and wear and tear. It measures the force required to embed an 11.28 mm steel ball into wood to half the ball’s diameter, and it measures the indentation. The Janka hardness rating determines whether a species is suitable for use as flooring. While oak is very hard, and is the industry go-to for flooring, there are other species that are much harder.
