Standardized specimens made of plastic are used to determine material properties and are referred to as test specimens. They are produced in defined shapes and dimensions to ensure reproducible and comparable measurement results. These specimens are used to test mechanical, thermal, and chemical properties such as tensile strength, impact resistance, and heat deflection temperature. Their geometry and size depend on the specific test method and applicable standards such as DIN, ISO, or ASTM. The use of standardized test specimens enables precise quality control and supports material development in plastics engineering.
