Plastic Film and sheets tensile test ISO 527-3 is a common international standard that is used to determine the tensile properties of plastic film or sheeting - a plastic test specimen with a thickness less than 1 mm. The tensile properties include tensile strength, yield strength, yield strain, strain at break, and in some cases Young's Modulus. Due to the flexible, delicate nature of these plastic specimens, both gripping and strain measurement can be a challenge.

ISO 527-3 Tensile Test of Plastic Thin Film Sheet

ISO 527-3 covers the specimen preparation requirements of thin plastic sheets and films. Thin plastic specimens created with the practices of ISO 527-3 are tensile tested with the practices of ISO 527-1. Thin plastic specimens created in accordance with ISO 527-3 are cut, or punched from a sheet of thin plastic.

ISO 527-3 specifies that thin plastic film of sheet specimens must be free from cracks or scratches that will affect the tensile test. ISO 527-3 allows for four specimen geometries that can be used for tensile testing. There are three acceptable dogbone shaped specimens that are acceptable. Specimen created following ISO 527-3 can be used to determine the tensile properties of thin plastic sheets and films including the tensile modulus of elasticity and the tensile energy to break (TEB).
