Significance and Use

5.1 Dissipation factor, permittivity, and dc volume resistivity are properties of communication cable fillers and filler components that are controlled in order that the cable's electrical performance falls within its design limits. Relatively small amounts of contaminants, such as polar compounds, water, or salts degrade the cable's electrical properties. Limits on the dielectric properties of the cable filling compound are usually specified by the cable manufacturer, by industry standards or both.

Scope

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 Whenever two sets of values are presented, in different units, the values in the first set are the standard, while those in parentheses are for information only.

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific hazard statements are given in Section 7.

1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
