These standards apply to materials, constructions, and testing of cross-linked rubber-insulated wires and cables which are used for the tansmission and distribution of electrical energy for normal conditions of installation and service, either indoors, aerial, underground, or submarine.

In classifying cross-linked insulations and jackets in these standards, the term “rubber” when used alone without further description shall mean either natural rubber or synthetic rubber, or a combination of these materials.
