Tensile Properties of Thin Plastic Sheeting

Standard Test Method for Tensile Properties of Thin Plastic Sheeting

This test method covers the determination of tensile properties of plastics in the form of thin sheeting and films (less than 1.0 mm (0.04 in.) in thickness). Film is defined in Terminology D883 as an optional term for sheeting having a nominal thickness no greater than 0.25 mm (0.010 in.). Tensile properties of plastics 1.0 mm (0.04 in.) or greater in thickness shall be determined according to Test Method D638. This test method can be used to test all plastics within the thickness range described and the capacity of the machine employed. Specimen extension can be measured by grip separation, extension indicators, or displacement of gage marks. The procedure for determining the tensile modulus of elasticity is included at one strain rate. The modulus determination is generally based on the use of grip separation as a measure of extension; however, the desirability of using extensometers, is recognized and provision for the use of such instrumentation is incorporated in the procedure. Test data obtained by this test method is relevant and appropriate for use in engineering design. The values stated in SI units are to be regarded as the standard. The values in parentheses are provided for information only. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
