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.
