Keywords of ASTM D882-18:modulus of elasticity plastic film plastic sheeting tensile properties tensile strength toughness yield stress. Toe compensation shall be made in accordance with Annex A1 unless it can be shown that the toe region of the curve is not due to the takeup of slack, seating of the specimen,or other artifact, but rather is an authentic material response. Properties such as tensile stress, elongation and modulus can be calculated. Various techniques for specimen gripping and extension measurement are addressed.Depending on the elongation of the material and the desired properties to be gained from the testing, various combinations of grip separation and test speed are utilized. No dumbbell shape is cut for materials of that thickness. Force and or extension are recorded during the test. A specimen of uniform cross-section is loaded in tension via means of a mechanical testing machine. The samples are cut in strips that minimally have to be eight times longer than wide. ASTM D882-18 covers the determination of tensile properties of plastics in the form of thin sheeting and films. Force and or extension are recorded during the test. ASTM D882 is used to measure tensile properties including ultimate tensile strength, yield strength, elongation, tensile energy to break and tensile modulus of elasticity of thin plastic sheeting and films. Jenny from Canada shared ASTM D882-18,whose title is Standard Test Method for Tensile Properties of Thin Plastic Sheeting.ĪSTM D882-18 covers the determination of tensile properties of plastics in the form of thin sheeting and films.Ī specimen of uniform cross-section is loaded in tension via means of a mechanical testing machine.
