1) Tablet breaking force : it is the force required to cause
them to fail in a specific plane. the breaking force of tablet is
commonly called tablet hardness in the pharmaceutical literature
but the use of this terrm is misleading because the in material
science the term hardness refers to the reisitance of a surface to
penetration or indentation by a small probe, so it is more
appropiriate to use tablet breaking force then the tablet hardness.
tensile strength measurement provides a more fundamental measures
of the mechanical strength of the compacted material and takes into
account the geometry of the tablet, if tablet fail in tension then
the breaking force can be used to calculate the tensile strength ,
in the cylindrical taablet fail in tension as indicated by a clean
spilt into halves under diametral compression the breaking force
may be used to ccompute the tensile strength by the equation
, and the bending or flexure of tablets is another option for
determining the tensile strength of cylindrical tablet in this
tablet they are 3 points flexure.
