ActiveMeasuring method for the shielding effectiveness of magnetic material in low frequency alternating magnetic field
磁性材料在低频磁场中屏蔽效能的测量方法
Application Summary AI generated
This standard specifies the measurement method for evaluating the shielding effectiveness of magnetic materials against low-frequency alternating magnetic fields, typically in the range of 20 Hz to 100 kHz. It is applied in industries such as electronics, telecommunications, and power equipment, where materials are tested to ensure they can attenuate magnetic interference in components like transformers, sensors, or shielding enclosures. The method provides a consistent procedure for quality control and material selection in product development and compliance testing.
