RELATIVE HARDNESS Table
(Janka) |
|
For
Domestic & Exotic Wood Flooring Species:
The Janka (or side) hardness test
measures the force required to embed a .444 inch steel ball to half its
diameter in wood. This is one of the best measures of the ability of wood
species to withstand denting and wear. It is also a good indicator of how
hard a species is to saw or nail.
The higher the number
the harder the wood
