This specimen is used to obtain reproducible measurements of a material's strength, stiffness, and elasticity under tension. It is the preferred specimen for rigid plastics up to about 7 mm thick and allows for direct comparison of tensile data between different materials and laboratories.

This specimen is recommended when a material does not break in the narrow section using a Type 1 specimen. Its significantly reduced width in the parallel section ensures that the specimen will properly fail in the intended area.

This specimen is specifically designed for testing non-rigid plastics and thin sheeting with a thickness of 4 mm or less. It is also used to measure the cross-flow properties of materials.

This is the preferred specimen geometry for ISO tensile tests on rigid and semi-rigid plastics. It is used to measure tensile strength, tensile modulus, and elongation, which are critical metrics for engineers to understand a material's performance under pulling forces.

This specimen is an alternative to the Type 1A and is commonly used when specimens are machined from sheets. It is used to determine the tensile properties of rigid and semi-rigid plastics, and features a different gauge length due to its larger radius and shorter parallel area.
