Schopper Type Tensile Tester

The machine in designed for determining the tensile  strength of  sheet  material such as paper, paper board,  plastics, metal foil, etc. The testing is made by inserting a sample between  two vertical  grips, and increasing the load until the sample  breaks. The elongation of the sample is measured simultaneously.

Determination occurs by means of  a pendulum balance. When the inserted sample is subjected to a  strain,  the pendulum will make a deflection is indicated on a scale  directly in kilograms. Different load weights for the pendulum correspond to the respective graduation.The graduation 0-500 g only correspond to bare pendulum without extra load.

The elongation is determined by measuring the increase in the distance between the clamps, which is indicated on the elongation scale. This scale has graduation in millimeters and in  per  cent based  on  180 mm testing length (which is a  standard  in  paper testing).  Should the elongation be wanted in per cent  based on other testing lengths, this must be calculated.

Tensile Strength Tester (schopper type ) meets the requirements laid down in the testing standards as per  TAPPI standards
