The acceptance hardness value is more than 8HW(which is equivalent to 52HBS). This is the most common method of hardness testing used for CNC and machining purposes, and the Rockwell, Vickers, Shore, and Brinell Hardness scales are all based on Indentation Hardness. We know to keep pace in this competitive industry, we have to innovate and continually upgrade our testers as new alloys come along, for instance. But with these tables it is concluded that because of different hardness test methods defining a single conversion method is not possible, Thats why these standards formulate tables for conversion process, with test load and hardness ranges.
