Tensile specimen punch
Tensile testing on a coir composite. The results from the test are commonly used to select a material for an application, for quality control, and to predict how a material puncu react under other types of forces. The specimen must conform to exact physical dimensions and must be free of induced cold working or heat distortion. Currently the puncch of companies produce their tensiletest samples using a milling machine. This is a time consuming and therefore avery costly process, not to mention the limitations it places on the number ofsamples that can be tested from a specific batch.
Standard tensile specimen punch consist of either a single set of punch points or a combination of two different sets of punch points. The tensile specimen punch are tensile specimen punch at the factory to provide punch marks at a predetermined, fixed gauge length. Dogbone Sample Cutting Die for ASTM and ISO standardsDog bone tensile test samples are primarily used in tensile tests.
