Establishes electrical ratings and test requirements of cable joints used with extruded and laminated dielectric shielded cable rated in preferred voltage steps from 2500 to 500 000 V. Also defines test requirements for cable jacket and cable shielded restoration devices; and defines a variety of common joint constructions. Designed to provide uniform testing procedures that can be used by manufacturers and users to evaluate the ability of underground power cable joints, and associated cable shield and cable jacket restoration components, to perform reliably in service.
