The breaking force of tablets is commonly called hardness in the pharmaceutical literature; however, the use of this term is misleading. In material science, the term hardness refers to the resistance of a surface to penetration or indentation by a small probe. The term crushing strength is also frequently used to describe the resistance of tablets to the application of a compressive load.

Frequently the tablet size denotes a required dose, whether it is a vitamin or a dishwasher additive, and nobody wants either a quarter mint in the bottom of a packet or a whole one that is too hard to crack. Other factors are important, including the pattern of breaking, but the crush strength is a primary indicator of manufactured quality.
