The Hard Truth of Conversions: ASTM E140

March 10, 2023

The Rockwell hardness test is one of the fastest and most convenient hardness testing methods used around the world. With the lack of sample prep and optical requirements, it is the easiest to work into automated production lines, and the common Rockwell hardness scale C (HRC) is an easy way to refer to the hardness of metals that even the lay person can understand. However, it is not the only hardness testing method. Knoop (HK) and Vickers (HV) hardness testing methods can also find the hardness of a material, but the values are not interchangeable. To compare material hardness, the values must be in the same hardness scale.

Coal and other biofuels are no different from every other substance that can be bought and sold: the quality of the material plays a huge role in the determination of the price. With coal and other solid fuels, the amount of volatile matter is the main factor in quality, as this determines the burning rates of the fuel. While the volatile matter value does rely on the type of fuel and moisture content of said fuel being tested, it also varies based on the heating rates used in the tests to determine the value.
