Hard Wood Flooring Hardness Table
How hard is your hard wood floor?
Below is a hard wood flooring hardness table. Without getting too technical, the hardness test undertaken here is one where a steel ball, of 0.44″ (11.2mm), is forced into the surface of the wood. The amount of force it takes to drive the ball 1/2 its depth into the wood is the figure quoted in the table. The information here comes from the U.S. Forest products Laboratory.
So if you want an super hard wood, look for the higher numbers next to the timber species.
