If you ask your self what is all about the Janka Hardness Floorsincalifornia.com will explain that The Janka Hardness is a test In wich we measure the hardness of the wood. In the Janka Hardness test Floors in california measures the force required to push a steel ball with a diameter of 11.28 millimeters ( 0.444 inches )into the wood to a depth of half the ball’s diameter (the diameter was chosen to produce a circle with an area of 100 square millimeters). In the past the Janka harness test were expressed in units of pressure, but when the American Society for Testing and Materials standardized the test it called for results in units of force.
