This Standard covers mechanical and electrical requirements for filled@ polyolefin insulated@ copper conductor@ buried telecommunications wire. It provides alternative choices for type of insulation@ type of filling compound@ sheath design (shielding materials@ single or double jackets@ and jacket type and thickness) and armoring. Buried wire is used to extend buried telephone plant from the distribution cable to the subscriber. PURPOSE: The purpose of this Standard is to establish generic technical requirements that may be referenced by individual telecommunications wire specifications covering products intended for normal outside plant use. The parameters covered provide material@ construction@ and performance requirements. Because this Standard does not cover all details of individual wire design@ it cannot be used as a single document for procurement of product. It is intended to be used in conjunction with an individual product specification that provides complete design details for the specific wire type and designates the applicable performance requirements. Such individual wire specifications may be prepared either by the user or the manufacturer. The specification designated for procurement is at the option of the user.
