This specification covers the requirements, sizes, construction, tests, and procedures for unused ropes for use by electrical utilities and related industries on energized lines operating at voltages higher than a certain value. Electrical test shall be performed in order to determine the rope´s electrical conductivity and resistivity to water. Physical properties such as hardness, diameter, breaking strength, elongation, and melt point shall be determined as well. Rope and strands shall be free from kinks, strand knots, and darting yarns or loose ends (inside yarns which project through cover yarns of strand at intervals along the rope).
