Janka wood harness testing the janka hardness test method measures the amount of force required to embed a 444 inch steel ball to one half of its diameter in wood. In the flooring industry both janka wood hardness testing and brinell wood hardness testing are used to measure the amount of indentation into the wood using force.

If you re interested in buy it for life wood flooring you re going to need to make hardness and scratch resistance a priority in the hardwood flooring industry the janka hardness test is the standard approach to measuring how resistant a wood sample is to both denting and wear.
