Application Summary AI generated

This standard specifies the method for performing DC voltage withstand tests on electric cables and wires to assess the integrity of their insulation under high-voltage stress. It is applied in manufacturing quality control and type testing for power cables, control cables, and communication cables, particularly in contexts where DC systems are used, such as in photovoltaic installations or railway electrification. The test helps verify that cables can safely operate at rated DC voltages without insulation breakdown.
