Physical Property Testing Definitions The ability of a material to withstand a load under tension, i.e. when being pulled apart. Tensile Strength It is expressed in pounds per square inch (psi). The amount a product will stretch under tension before it breaks. Expressed in percent of Elongation its original length, i.e. a tensile elongation of 10% means the product stretched 10% more than its original length before breaking. A value that is the ratio of the breaking strength to the deformation at break of a given material. It indicates the relative rigidity and strength of a material. The ratio of normal Modulus of Elasticity stress to corresponding strain of a material. The ratio of normal stress to corresponding strain for tensile or compressive stresses below the proportional limit of the material; referred to as elastic modulus or Young's modulus. Die "C" Tear, pli The amount of force required till break of the "pre-notched" sample. Hardness The relative resistance of a material to scratching. Hardness, Shore A A measure of elastomer hardness. Hardness, Shore D A measure of elastomer hardness. **Everyone should have this Glossary from PDA, it’s Very Helpful. 2013 PDA Annual Conference Flamingo Las Vegas Hotel and Casino April 15 – 17, 2013
