Guidelines to hardness testing - Hegewald Peschke

Hardness testing devices that work according to the Rockwell procedure are the most widespread. The most important advantages are: deviations due to personal estimations are avoided; it is less sensitive to rough surfaces (even though the standard says that surfaces have to be flat and carefully abraded).

Metallographic grinding and polishing insight Struers

In addition, when processing several specimens in a holder, care must be taken to make sure they are all at the same level, or "plane," before progressing to the next step, fine grinding. To obtain a high, consistent material removal rate, short grinding times and maximum flatness, totally fixed grains with a relatively large grain size are preferred for plane grinding.
