This test method covers the determination of the tensileproperties of unreinforced and reinforced plastics in the form ofstandard dumbbell-shaped test specimens when tested under definedconditions of pretreatment, temperature, humidity, and testingmachine speed.This test method is applicable for testing materials of anythickness up to 14 mm (0.55 in.). However, for testing specimens inthe form of thin sheeting, including film less than 1.0 mm (0.04in.) in thickness, ASTM standard D882 is the preferred test method.Materials with a thickness greater than 14 mm (0.55 in.) shall bereduced by machining.This test method includes the option of determining Poisson'sratio at room temperature.NOTE 1—This standard and ISO 527-1 address the same subjectmatter, but differ in technical content.NOTE 2—This test method is not intended to cover precisephysical procedures.
