The spark-test method specified in this standard is intended for the detection of defects in the insulation or sheathing layers of electric cables. For single-core cables with no outer metallic layer, the general process is accepted as being equivalent to subjecting samples of those cables to a voltage test in water.
This standard specifies the operational requirements for the spark-test equipment, as well as the principal characteristics, functional parameters and calibration procedures for each type of test equipment.
