ASTM D4872 : 99(2010)

Standard Test Method for Dielectric Testing of Wire and Cable Filling Compounds

Standard Details

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 StandardDetails or both.
