ASTM B869-02

Standard Specification for Copper-Clad Steel Electrical Conductor for CATV Drop Wire

SCOPE
1.1 This specification covers 21 % conductivity hard-drawn round copper-clad steel wire for coaxial cable center conductors (Note 1).
Note 1—Wire ordered to this specification is not intended for redrawing since it is furnished in the hard-drawn temper. If wire is desired for the purpose, the manufacturer should be consulted.
1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
