ISO 527-3 specifies the conditions for determining the tensile properties of plastic films or sheets less than 1 mm thick, based upon the general principles given in ISO 527-1. The tensile properties include tensile strength, yield strength, yield strain, strain at break, and in some cases Young's Modulus.
This test standard is equivalent to BS EN ISO 527-3:2018.
Before conducting ISO 527-3, it is important to read the entire specification. Standards can be obtained from appropriate standard authorities.
