The scale used in the table is pounds force.
Hardest wood flooring janka scale.
It measures the force required to embed an 11 28 millimetres 0 444 in diameter steel ball halfway into a sample of wood.
The janka test measures the amount of force needed to drive a 0 444 inch steel ball into wood to a depth equal to half its diameter.
This test is one of the best measures of the ability of a wood specie to withstand denting and wear.
The janka test measures the amount of force required to embed a 0 444 steel ball into the wood to half of its diameter.
The janka test was developed as a variation of the brinell hardness test.
The test measures the force required to push a steel ball with a diameter of 11 28 millimeters 0 444 inches into the wood to a depth of half the ball s diameter.
The janka hardness scale starts at zero with this option being the softest wood choice making it easy to dent and scratch.
Woods with a higher rating are harder than woods with a lower rating.
Though no wood on the scale has this rating a rating like this would not make for a good floor.
The diameter was chosen to produce a circle with an area of 100 square millimeters.
The janka test measures the force required to embed a 444 inch steel ball into the wood by half its diameter.
The hardness of a wood is rated on an industry wide standard known as the janka test.
