The hardness of a wood is rated on an industry wide standard known as the Janka test. The Janka measures the force required to embed a .444 inch steel ball into the wood by half its diameter. This test is one of the best measures of the ability of a wood specie to withstand denting and wear. It is also a good indicator of how hard a specie is to saw, mill and nail.
There are many things to consider when choosing your wood, including the hardness, natural colour of the wood, the grain and the stability.
How Stable is Your Wood?
Stability is defined by the level of flux, expansion and "movement" a wood will have when exposed to different humidity levels. Certain woods need to be dried longer in the mill, and some also need to be acclimatized in your home, to create a more stable presence. Maple and Hickory however are two species, that are not to be acclimated in your home.and doing so will void the warranty on your hardwood floors. These woods tend to take on moisture quicker than other species, so these floors should be installed immediately upon arriving at your home.
