The comparative hardness levels of a particular type of wood could be measured by the Brinell or Janka hardness tests.
The type of wood floor you’ve got in your home can dictate how often the flooring will need to be refinished or may need replacing in its entirety. Some species of wood, such as pine are comparatively soft so will indicate easier than forms made from wood species such as oak.
The Brinell test measures the hardness of the timber by pushing a steel ball into the wood with a specific force. The ball includes a predetermined diameter and the impression left by the ball is subsequently utilized to assess the relative hardness of their wood. It follows then that the bigger impression left by the ball the thicker the wood. This is repeated at several areas across the wood surface and an average figure for hardness determined.
The other method used to measure relative wood hardness is called the Janka test. This method also uses a metal ball of a predetermined diameter.
However in this case the ball is pushed to the wood until half of the ball’s diameter is put within the timber surface. The force required to do this is measured and it is this that will be utilized to ascertain the relative hardness of the timber.
