Janka Hardness
Hardness and Durability: Probably the most important strength property for wood
used in flooring application it is side hardness, also known as Janka hardness.
Side hardness represents the resistance of wood to wear, denting and marring.
It is measured by load required to embed a 0.444-inch steel ball to one-half
its diameter in the wood. Janka Hardness rating are generally based on an average
of test on both tangential and radial ( plainsawn and quartersawn) sample. The
test 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.
