    This document is not applicable to connectors for overhead line conductors nor to connectors with a sliding contact.<\/p>\n

    The object of this document is to define the type test methods and requirements which apply to compression and mechanical connectors for power cables with copper or aluminium conductors. The reference method is to perform the tests on unused conductors.<\/p>\n
