Note 2-This test method is not intended to cover precise physical procedures. Note 1-This test method and ISO 527-1 are technically equivalent. Materials with a thickness greater than 14 mm (0.55 in.) must be reduced by machining.1.3 This test method includes the option of determining Poisson's ratio at room temperature. However, for testing specimens in the form of thin sheeting, including film less than 1.0 mm (0.04 in.) in thickness, Test Methods D882 is the preferred test method. Scope1.1 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.1.2 This test method can be used for testing materials of any thickness up to 14 mm (0.55 in.).
