Application Summary AI generated
This standard specifies a rapid test method for determining the temperature index of enamelled winding wires, which is the temperature at which the wire's insulation life is reduced to 20,000 hours under thermal aging. It is applied in the electrical engineering industry for quality control and material qualification of magnet wires used in motors, transformers, and other electromagnetic devices. The quick-test method allows manufacturers and testing laboratories to efficiently evaluate thermal endurance without requiring the extended duration of conventional aging tests.
