Application Summary AI generated

GB/T 3048.9-2007 specifies the spark test method for detecting defects in the insulation of electric cable and wire cores during production. It is applied in manufacturing quality control to identify pinholes, cracks, or thin spots in the insulation layer by passing the core through a high-voltage electrode. This standard is primarily used in the cable and wire industry for continuous in-line testing of insulated conductors to ensure electrical safety and compliance with performance requirements.
