Janka Hardness Scale Measuring wood hardness
Janka hardness testing The actual number listed in the wood profile is the amount of pounds-force (lb f) or newtons (N) required to imbed a .444″ (11.28 mm) diameter steel ball into the wood to half the ball's diameter. This number is given for wood that has been dried to a 12% moisture content, unless otherwise noted.
What is Janka Hardness Rating? Pinnacle Floors
The Janka Hardness Scale determines the hardness of a particular type of wood over another. The scale was invented in 1906 by Gabriel Janka, an Austrian wood researcher, and standardized in 1927 by the American Society for Testing and Materials (ASTM).
Janka Hardness Test What is a Wood Janka Rating? LL Flooring
Janka Hardness Scale is simply a scale that ranks species of wood, based on their hardness. The hardness is determined by testing the amount of force necessary to implant a steel ball into a plank of wood. The result is that the hardness, resistance, and durability of the wood are tested using this method. The harder the wood, the more force is.
The Janka Hardness Scale Some Important Facts You Should Know
The Janka wood hardness scale lists the hardness of wood species where the highest ranking makes up the hardest woods. This guide outlines 113 domestic and foreign species of wood, with their hardness scale rating. Janka Wood Hardness Scale Chart
Janka Scale Musolf's Wood Flooring
Wood species vary in many ways, but a key factor in finishing wood is the hardness of the wood. A common measurement for wood hardness is the Janka scale. The Janka scale measures the resistance of a sample of wood to denting and wear and is typically expressed in lbf (pounds-force) or N (Newtons). The US typically will use lbf.
Janka Hardwood Scale
The Janka hardness test ( English: / ˈdʒæŋkə /; [1] German: [ˈjaŋka] ), created by Austrian-born American researcher Gabriel Janka (1864-1932), measures the resistance of a sample of wood to denting and wear [citation needed] It measures the force required to embed an 11.28-millimeter-diameter ( 7⁄16 in) steel ball halfway into a sample of wood.
Janka Hardness Scale Learn How Hard Each Wood Species Is
As such, it is recommended to use the Janka scale in combination with other tests and evaluations when making decisions about the suitability of wood for different applications. Overall, the Janka hardness scale is a valuable tool for determining the hardness and durability of various types of wood and is widely used by lumber suppliers.

A Homeowner's Guide to Hardwood Floor Hardness Flooring Products
The industry standard method for determining the hardness of wood products is called the Janka hardness test. Janka hardness of a given wood species is defined by a resistance to indentation test as measured by the load (pounds of pressure) required to embed a 11.28mm or 0.444" diameter ball to one-half its diameter into the wood.
Janka Scale Hardwood Flooring Hardness Guide
The Janka Test is a measure of the hardness of wood. 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 Wood Hardness Scale Woodwudy Wholesale Flooring
The Janka hardness scale is a measurement that determines a wood sample's resistance to denting or wear. It was developed in 1906 by Gabriel Janka, an Austrian-born American wood researcher. His method is now accepted as the standard for ranking a wood's hardness. The results of the test are straightforward: the higher the number on the.
What Is the Janka Wood Hardness Scale? The Family Handyman
The Janka hardness scale measures the force that's required to embed a steel ball halfway through a sample of wood. The ball is 0.444 inches in diameter and fired with increasing force. The pounds of force (or newtons if you're using the metric system) needed to push the ball to the center is the Janka value you end up with.

What is the Janka Hardness Scale? Hardwood Decking Supply
The Janka Wood Hardness Scale refers to a range of numbers that determine how dense a type of wood is and how resistant to dents, dings, and wear that a type of wood will be once installed. Ipe - 3510 Wallaba - 2040 Hickory - 1820 Hard Maple - 1450 French White Oak - 1360 American White Oak - 1360 Antique Oak - 1325 Red Oak - 1290
Hardwood Flooring and Understanding the Janka Hardness Scale
The Janka scale, simply put, records the density of wood by testing its resistance to denting. The test measures the force required to embed a .444-inch (11.28mm) diameter steel ball halfway into a piece of wood. That force is recorded in pounds-force (lbf) in the U.S. or in kilograms-force (kgf) or newtons (N) in other parts of the world.
