Janka is the unit of  measurement used  
to  describe  the  surface  hardness  of  a
wood  flooring  product.   This   rating  is
equal to the amount of  force required  to
drive  a   0.444   inch  steel  ball,   half  its
diameter,  into  the  surface of  the  wood
being tested.

The Janka rating  is  a  good  indicator  of
how  easily a wood product will dent and
wear over time.

Northern  Red  Oak  (1290 Janka)  is  the
“Gold Standard” against  which  all  other
woods are measured.
