Abstract
This guide identifies the standard test methods to use in evaluating unsintered extruded films or tapes manufactured from polytetrafluoroethylene (PTFE). The test methods covered here shall be capable of investigating the following material properties: width; thickness; tensile properties (tensile strength and elongation); specificat gravity (relative density); residual extrusion aids or other volatile components; dielectric constant; volume resistivity; dielectric breakdown voltage; and unit weight.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
1. Scope
1.1 This guide identifies test methods to use in evaluating unsintered extruded films or tapes manufactured from polytetrafluoroethylene.
1.2 The values stated in SI units as detailed in IEEE/ASTM SI 10, are to be regarded as standard.
1.3 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.
Note 1???
This test method is equivalent to ISO 12086-2:2006 in the measurement of tensile properties, specific gravity, and dielectric constant. These are in ISO 12086-2:2006, sections 8.2.2, 10.6 and 8.1.1. It is not equivalent to ISO 12086-2:2006 in any other measurement or section..
