Wood Hardness Testing: Know Your Materials

The Janka scale rates the relative hardness of a species of timber. The scale was devised by Gabriel Janka, an Austrian wood researcher in 1906. It had been standardized in 1927 from the American Society for Testing Materials with the score ranging from 0-4000. The simplest approach to gauge the amount with regard to the timber is: the greater the number, the harder the wood. The hardness is measured by the amount of force required to embed a .444 inch steel ball to half its diameter into the wood. This shows how much wear and tear a certain species of timber can take and can also indicate the quantity of work it would take to nail or saw.

However, this evaluation is still just a general guideline when it comes to deciding on a species to your hardwood flooring. Actually, the results vary based on where the wood has been chosen in addition to its plank structure and finish. Surprisingly, the hardness of the timber does not affect the price of the wood. It is rather directly related to how available and accessible the species of timber is, rather than its hardness.

Most hardwoods are durable enough to withstand normal use for floors, particularly when properly completed and installed. However, no matter how high the Janka score is, all of wood dents with tough enough effect.
