Designation: D1708 – 10 Standard Test Method for Tensile Properties of Plastics by Use of Microtensile Specimens 1 This standard is issued under the fxed designation D1708; 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. This standard has been approved for use by agencies of the Department of Defense. 1. Scope* 1.1 This test method covers certain material specifcations For which a history oF data has been obtained using the standard microtensile specimen. The specimen geometry has been changed to be equivalent to that oF ISO 12086-2:1995 .I n general, this test method is superseded For general use by either Test Methods D882 or Test Method D638 . The very small Type V specimen in Test Method D638 is the recommended speci- men when limited amounts oF material are available. 1.2 This test method covers the determination oF the com- parative tensile strength and elongation properties oF plastics in the Form oF standard microtensile test specimens when tested under defned conditions oF pretreatment, temperature, humid- ity, and testing machine speed. It can be used For specimens oF any thickness up to 3.2 mm ( 1 / 8 in.), including thin flms. 1.3 This test method cannot be used For the determination oF modulus oF elasticity. ±or the determination oF modulus, see Test Method D638 or Test Methods D882 . 1.4 Test data obtained by this test method are relevant and appropriate For use in engineering design. 1.5 The values stated in SI units are to be regarded as standard. The values given in parentheses are For inFormation only. 1.6 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 1—There is no known ISO equivalent to this standard. 2.
