BREAKING STRENGTH

   Breaking Strength is measured by applying weight at the center
   of testpiece, and calculated as follows:



  Formula:
                 8 x L
         S =  ------------  x  W
                 ƒÎD3


  where,
   
        S: Value (kgs/cm2) of Transversal Breaking Strength
        D: Diameter (cm) of Carbon Rod 
        L: Distance (cm) between two Supporting Edges
        W: Applied Load (kgs) when Carbon Rod is broken
