ASTM D882

Test Materials: ASTM D882 specifies the use of flexible plastic film specimens, typically cut into strips. These materials should be representative of the final product and free from defects, with dimensions and thicknesses defined in the standard to ensure uniformity in testing.

Test Process: The test process involves subjecting the plastic film specimens to a tensile test using a tensile testing machine. Samples are pulled at a constant speed until failure, with parameters such as temperature and humidity controlled according to the standard. Proper setup and calibration of the equipment are critical for accurate results.

Test Result Interpretation: Results from ASTM D882 are analyzed through the stress-strain curve, which provides key metrics such as tensile strength, elongation at break, and modulus of elasticity. These values help assess the mechanical properties of the plastic films, ensuring they meet performance requirements for their intended applications.
