Janka Hardness Ratings
The Janka hardness test is the hardness level given to each species. Hardness is expressed in kilo newtons; the Janka rating is a measure of the wood to resist indentation. It is one of the best measures of the ability of a wood species to withstand denting and wear. The higher the Janka rating / number the greater the hardness.
The higher the Janka Rating, the harder the timber is.
