Test Apparatus & Method
A tablet is placed between two platens (jaws), one of which is attached to a force gauge with load cell and the other to a motor which provides the mechanical drive.
The motorised jaw drives forward pressing the tablet against the fixed jaw until the tablet breaks. The motorised jaw then retracts and the load force required to break the tablet is recorded.
The units of force normally employed to quantify breaking force are Kiloponds (Kilogram-Force) or Newtons.
