What is the IEC 61000 4 8 test ?

IEC 61000-4-8 is an essential standard for evaluating the immunity of electrical and electronic equipment to power frequency magnetic fields. The standard defines the procedures and criteria for testing the equipment to ensure its immunity to these fields.

The testing procedures for IEC 61000-4-8 typically involve the use of a device called a "magnetic noise generator" that generates low-frequency magnetic fields. The equipment being tested is then placed in the noise generator and the device is continuously activated for a period of time.

The criteria for the testing procedure are based on the equipment's ability to operate correctly and safely in the presence of these magnetic fields. The equipment is expected to remain functional and operational even when exposed to the magnetic fields, without suffering damage or malfunction.

Conclusion

IEC 61000-4-8 is an important standard for ensuring the safety and reliability of electrical and electronic equipment that are used in various industries. The test is crucial for evaluating the equipment's immunity to power frequency magnetic fields and ensuring it can operate correctly and safely in these environments. By following the procedures and criteria defined by the standard, manufacturers can ensure that their equipment meets the necessary requirements for safety and reliability.
