A test procedure for impulse testing of insulated conductors (cables) and cables with accessories installed (cable systems) is provided in this standard. This procedure can be used as a design or qualification test for cables or for cable systems. This test procedure is not intended to replace any existing or future standards covering cable or cable accessories, impulse generators, impulse testing, or voltage measurements. It is intended to supplement such standards by providing specific procedures for impulse testing on specific type of cables, accessories, or cable systems.

Recommended Practice for Impulse Voltage Tests on Insulated Cables and Their Accessories
This recommended practice applies to both switching impulse and lightning impulse tests on insulated cables incorporating laminated or extruded insulations and their accessories. This recommended practice applies to individual cable accessories only when referenced by the specific accessory standard. This recommended practice does not apply to cables or cable systems that utilize gas or gas spacers as the sole insulating medium.
