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
