Unformatted text preview: Designation: D882 10 Standard Test Method for Tensile Properties of Thin Plastic Sheeting 1 This standard is issued under the fixed designation D882; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon ( ) indicates an editorial change since the last revision or reapproval. These test methods have been approved for use by agencies of the Department of Defense to replace Method 1013 of Federal Test Method Standard 406. 1. Scope* 1.1 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). N OTE 1Film is defined in Terminology D883 as an optional term for sheeting having a nominal thickness no greater than 0.25 mm (0.010 in.). N OTE 2Tensile 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 can be used to test all plastics within the thickness range described and the capacity of the machine employed. 1.3 Specimen extension can be measured by grip separation, extension indicators, or displacement of gage marks. 1.4 The procedure for determining the tensile modulus of elasticity is included at one strain rate. N OTE 3The modulus determination is generally based on the use of grip separation as a measure of extension; however, the desirability of using extensometers, 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 informa- tion only. 1.7 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 appro- priate safety and health practices and determine the applica- bility of regulatory limitations prior to use. N OTE 4This test method is similar to ISO 527-3 , but is not considered technically equivalent. ISO 527-3 allows for additional specimen configu- rations, specifies different test speeds, and requires an extensometer or gage marks on the specimen. 2.
