The Hardness Testing Methods Cheat Sheet is a one-page visual guide that compares three common hardness testing methods—Brinell, Rockwell, and Vickers—across several key criteria.

It outlines which materials each method is best suited for, including metals, ceramics, and coatings, and distinguishes between macrohardness and microhardness applications. The sheet also evaluates sample geometry compatibility, load requirements, and the level of test accuracy and precision.

Additionally, it highlights equipment availability and cost considerations, making it easy to choose the right method based on your testing needs. A simple key helps readers quickly identify recommended, possible, and not recommended uses for each method.
