ASTM D638 is the most common testing standard for determining the tensile properties of reinforced and non-reinforced plastics. With the use of plastics being at an all-time high, it is critical that manufacturers be able to properly gauge the mechanical strength of their materials.

The most common ASTM standard for tensile tests on plastics is ASTM D638. This standard is used to determine tensile properties of plastic materials for control, specification, qualitative characterization and research and development purposes.

Identify the components of the testing machine and parameters for the extension indicator based upon the measurement to be taken. Recognize specimen types, preparation requirements, and number of specimens to be used in testing. Describe how speed of testing is determined.

1.1 This test method covers the determination of the tensile properties of unreinforced and reinforced plastics in the form of standard dumbbell-shaped test specimens when tested under defined conditions of pretreatment, temperature, humidity, and testing machine speed.

2024年10月4日 · ASTM D638 provides standardized procedures for plastic tensile properties determination. It assesses plastic materials' ultimate tensile strength, elongation at break, and modulus of elasticity. ASTM D638 test is critical for plastics' mechanical reactivity and performance under stress.
