Scope

This part of GB/T 4074 specifies the method for determining the thermal life and temperature index of enameled round wires in normal-pressure air by constant-temperature life and dynamic thermal gravimetric tests, with the change in electrical strength as the criterion for failure. The test results can be used as a basis for selecting enameled round wires when evaluating the insulation structure of electrical equipment.
