Testresources Blog ASTM D882 vs. ISO 527-3: Understanding Two Approaches to Tensile Testing Thin Film Plastics

  ASTM D882 and ISO 527-3 both evaluate tensile properties of thin plastic films, but differ in specimen preparation, testing parameters, and data analysis. The choice between them depends on industry preferences, regulations, or material requirements. What Are the Similarities Between ASTM D882 and ISO 527-3? ASTM D882andISO 527-3are both go-to standards for tensile testing of plastic films and sheets. They share the goal of evaluating a material's response to pulling forces, analyzing properties like tensile strength, yield strength, and elongation at break. Both standards specify similar specimen shapes, such as strips or dumbbells, to be used in the testing process. The general procedures, including how the material is gripped and the rate at which it's pulled, also share many similarities.
