what is a hardness test
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 .The breaking force test, also known as the hardness test, offers a load range of up to 500N and allows users to set desirable test speeds (mm/sec) and force increments (N/sec). In addition to hardness measurement, the THT500 is capable of providing other measurements such as length, width, thickness, and weight (using an external scale).
