"Replace the first paragraph of this clause by the following: This standard deals solely with the conditions of steady-state operation of cables at all alternating voltages@ as well as in direct voltages up to 5 kV@ buried directly in the ground@ in ducts@ in troughs or in steel pipes@ both with and without partial drying-out of the soil@ as well as cables in air. The term ""steady state"" is intended to mean a continuous constant current (100 % load factor) just sufficient to produce asymptotically the maximum conductor temperature@ the surrounding ambient conditions being assumed constant."
