Hardness Testing of Pharmaceutical Tablets A technical primer for attorneys By Alberto Cuitiño Professor, Rutgers University 1. Introduction: What is harness testing? Hardness testing is a simple methodology to interrogate one of the key properties of tablets: the tensile strength. Tensile strength is the value of the stretching force

of Tablets The physical properties (crushing strength, thickness, and diameter) of 10 tablets of each formulation at each compression force were determined with a model PTB-311 Pharma Test tablet-test unit (Pharma Test, Switzerland). The disintegration time of the tablets was determined as the time necessary for the tablets to be completely

This is compression test for measuring the hardness of tablets (pharmaceutical tablets). In this video, a tablet is pushed until it breaks using IMADA force gauge and a flat attachment. This test determines the hardness of tablets by obtaining the maximum load value when fracture initiates. Watch the video for more details.

Hardness Theforce required to break tablet is measured in kilograms and a crushing strength of 4 KG is usually considered to be the minimum for satisfactory tablets. Oraltablets normally have a hardness of 4-10kg,However hypodermic and chewable tablets are usually much softer (3 kg) and some substained release tablets are much harder 10-20 kg.
