wood flooring hardness scale
The janka hardness test (from the austrian-born emigrant gabriel janka, 1864–1932) measures the resistance of a sample of wood to denting and wear. it measures the force required to embed an 11.28 millimetres (0.444 in) diameter steel ball halfway into a sample of wood. a common use of janka hardness ratings is to determine whether a species is suitable for use as flooring.. Understanding how the janka hardness scale works is simple! in short, a higher number (rating) on the janka scale equates to a harder wood species; the lower the number, the softer. a janka rating provides a great barometer for determining how well a particular floor may withstand denting and wear.. All these ratings have been organized onto a scale called the janka hardness scale. the janka hardness scale starts at 0 and goes through 4000, with 4000 being an extremely hard wood, so hard it is difficult to saw. the best wood for hardwood flooring typically falls above 1000 on the scale. image source: floorings.com.

The janka hardness test measures the force required to embed a .444 inch steel ball to half its diameter in wood. it is one of the best measures of the ability of a wood species to withstand denting and wear. the higher the number, the harder the wood is.this should be used as a general guide when comparing various species of wood flooring.. The janka scale is used to determine the relative hardness of particular domestic or exotic wood species. the janka test measures the amount of force required to embed a 0.444" steel ball into the wood to half of its diameter. woods with a higher rating are harder than woods with a lower rating. the scale used in the table is pounds-force..
