GB/T 3048.11-1994 Test methods for determining electrical properties of electric cables and wires.Dielectric dissipation factor measurement (English Version)
This standard specifies the test equipment, sample preparation, test procedure, test results, calculation and precautions for dielectric loss tangent test. This standard is suitable for measuring the dielectric loss tangent (tgδ) value of cables under power frequency AC voltage, but not for winding wire products. The general requirements and definitions of electrical performance tests of wires and cables and the requirements for periodic calibration of test equipment are specified in GB/T3048.1.
