This test method was designed to determine tensile properties of plastics based on the general principles given in ISO 257-1:2012. These properties include tensile strength, strain at break, modulus, and yield.
Products that may be tested in accordance with this standard include thermosets, thermoplastics, and fiber-reinforced plastics. Test specimens may be rigid, semi-rigid, molded, or extruded plastics and are commonly in the shape of a dumbbell or dog bone.
