ANSI/ICEA S-81-570-2012 Standard for 600 Volt Rated Cables of Ruggedized Design for Direct Burial Installation As Single Conductors or Assemblies of Single Conductors
This standard applies to the materials, constructions, and testing of single conductor cables and assemblies of completed single conductor cables used for the distribution of electrical energy at phase-to-phase voltages not exceeding 600 volts or phase to ground not exceeding 480V, and at temperatures not exceeding 75°C or 90°C, as applicable to the construction. It requires the use of ruggedized extruded insulations.
