Tensile strength: The maximum tensile force developed in a test specimen before rupture on a tensile test carried to rupture under prescribed conditions. Tensile strength is the force per unit width of teste specimen. Tensile index:The tensile strength in N/m divided by gramage Stretch at rupture:The maximum tensile strain developed in the test specimen before rupture in a tensile test carried to rupture under prescribed conditions.The stretch is expressed as a pecentage, i.e., one hundred times the ratio of the increase in length of the test specimen to the original test span.

A test piece is clamp between two jaws the upper clamp starts moving at a specified velocity. Without slipping and pulling apart so that the breaking occurs the maximum load at which the sample breaks measured on a digital panel meter using precision load cell method. The Tensile Tester is intended for determining the tensile strength and stretch at break of the paper, board, metal foil, textile and plastics. – with Digital Display of breaking peak load and peak stretch complete with memory for retaining peak value, automatic or normal zero setting, overload and over travel protection facilities.
