ISO 527-1 & ISO 527-2 Tensile Test on Plastics

This tensile test is used to determine essential mechanical properties of molding materials. These characteristic values are mostly used for comparison purposes. The standards ISO 527-1 (general principles) and ISO 527-2 (test conditions for molding and extrusion materials) describe tensile testing on plastics with a thickness of more than 1 mm. The guiding principle of the ISO 527 standard is the high reproducibility of test results across laboratories, companies and national borders.

More details about the tensile test on plastics can be found in the ASTM D638 standard. Plastic films and sheets with a thickness of less than 1 mm are described in the ISO 527-3 or ASTM D882 standards.
