ACTIVE STANDARD: D882-02 Standard Test Method for Tensile Properties of Thin Plastic Sheeting 1. Scope 1.1 This test method covers the determination of tensile properties of plastics in the form of thin sheeting, including film (less than 1.0 mm (0.04 in.) in thickness). Note 1Film has been arbitrarily defined as sheeting having nominal thickness not greater than 0.25 mm (0.010 in.). Note 2—Tensile properties of plastics 1.0 mm (0.04 in.) or greater in thickness shall be determined according to Test Method D638. 1.2 This test method may be used to test all plastics within the thickness range described and the capacity of the machine employed. 1.2.1 Static Weigbing, Constant-Rate-of-Grip Separation TestThis test method employs a constant rate of separation of the grips holding the ends of the test specimen. 1.3 Specimen extension may be measured in these test methods by grip separation, extension indicators, or displacement of gage marks. 1.4 A procedure for determining the tensile modulus of elasticity is included at one strain rate. Note 3The modulus determination is generally based on the use of grip separation as a measure of extension however, the desirability of using as described in 5.2, is recognized and provision for the use of such instrumentation is incorporated in the procedure. 1.5 Test data obtained by this test method is relevant and appropriate for use in engineering design. 1.6 The values stated in SI units are to be regarded as the standard. The values in parentheses are provided for information only. 1.7 Tbis standard does not purport to address all of tbe safety concerns, if any, associated with its use. It is the responsibility of tbe user of this standard to establish appropriate safety and bealth practices and determine the applicability of regulatory limitations prior to use Note 4This test method is similar to ISO 527-3, but is not considered technically equivalent. ISO 527-3 allows for additional specimen configurations, specifies different test speeds, and requires an extensometer gage marks on the specimen. 2.

Terminology 3.1 Definitions- definitions of terms and symbols relating to tension testing of plastics appear in the Annex to Test Method D638. 3.1.1 line grips- grips having faces designed to concentrate the entire gripping force along a single line perpendicular to the direction of testing stress. This is usually done by combining one standard flat face and an opposing face from which protrudes a half-round. 3.1.2 tear failure- a tensile failure characterized by fracture initiating at one edge of the specimen and progressing across the specimen at a low rate slow enough to produce an anomalous load-deformation curve. 4. Significance and Use 4.1 Tensile properties determined by this test method are of value for the identification and characterization of materials for control and specification purposes. Tensile properties may vary with specimen thickness, method of preparation, speed of testing, type of grips used, andmannerofmeasuringextension.Conseguently,whereprecisioncomparativeresultsare desired, these factors must be carefully controlled. This test method shall be used for referee purposes, unless otherwise indicated in particular material specifications. For many materials, there may be a specification that requires
