1.1 This test method covers the determination of dissipation factor, permittivity (dielectric constant) and ac volume resistivity of wire and cable filling compounds and related materials that are solid at room temperature, but capable of being melted at elevated temperature.

1.2 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. Specific hazard statements are given in Section 9.

1.3 The values stated in inch-pound units are the standard, except in certain instances where SI units are more appropriate. The values in parentheses are for information only.
