ASTM D882

Standard Test Method for Tensile Properties of Thin Plastic Sheeting

ASTM D882 Tensile Testing machine for plastic - Micom Laboratories

Micom Laboratories offers plastics testing to ASTM D882 as part of its material testing offering. This standard measures the tensile properties of thin plastic sheets and films, including tensile strength, yield strength, elongation, tensile energy at break and modulus of elasticity.

The samples are cut into strips that must be at least eight times longer than they are wide. No dumbbell shape is cut for materials of that thickness. Cut samples need to be free of nicks and other cutting defects, as they will have a significant impact on the variation of test results. The samples are tested in specific conditions of pre-treatment, sample orientation, temperature, humidity, and rate of pulling. ASTM D882 can be used for testing materials that are thinner than 1 mm in thickness. Thicker materials should be tested using ASTM D638, which is also part of our plastic testing services.

ASTM D882 Typical Experimental Parameters

  • Number of specimens per product: 5. In some cases, the tensile properties need to be measured both in the machine and perpendicular to the machine direction since they can vary substantially from one orientation to the other.  This behavior is called anisotropy.
  • Crosshead speed: Between 12,5 mm/min and 500 mm/min.  This varies as a function of the initial strain rate as given in Table 1 of the test method.
  • Specimen shape: Square strips 8 times longer than wider
  • Conditioning and testing temperature: 23 ± 2 °C.
  • Conditioning and testing relative humidity: 50 ± 5 %

Other Test Methods Related to ASTM D882 Tensile Testing

ASTM D882 is closely related to ASTM D638, which covers tensile properties for thicker plastic materials. Both standards are integral parts of our plastic testing and polymer testing services, ensuring that materials are evaluated across a wide range of thicknesses and use cases.
