Introduction
Purpose of the Project workMeasuring tablet hardness (breaking force) plays a vital role in defining dosage form with optimum physical characteristics and testing whether produced dosage form meets the defined specifications in manufacturing. Testing tablet hardness is more than ensuring the mechanical integrity of produced tablets during subsequent processes. Because the hardness of a tablet directly relates to all other physical parameters, it is a fast and efficient test that indicates whether specifications such as disintegration time and friability will be met.

Overall Hardness and Disintegration Time test of Collected 10 Antacid Samples
From the above table it was revealed that no such relation can establish between hardness and disintegration time. Sample A01 had 16.71 kg/cm2 hardness and DT was 35 min 2.5 sec. Again in sample A09 had 11.78 kg/cm2 hardness and DT was 32 min 11 sec. So no relation can be established between two parameters.
Conclusion
