What is the IEC 61000-6-4 standard?

The IEC 61000-6-4 is an international electromagnetic compatibility (EMC) standard that specifies the emission requirements and test methods for electrical and electronic equipment in industrial environments. It is part of the broader IEC 61000 series which covers EMC for various environments.

Why is the IEC 61000-6-4 standard important?

In today's interconnected world, industrial environments are filled with a multitude of electronic devices and equipment. These devices can emit electromagnetic disturbances that can interfere with the proper functioning of other devices or systems. The IEC 61000-6-4 standard ensures that equipment operated in industrial environments meets specific emission limits, reducing the risk of electromagnetic interference and ensuring reliable operation of all devices.

Key requirements of the IEC 61000-6-4 standard

The IEC 61000-6-4 standard sets certain emission limits for conducted and radiated disturbances caused by electrical and electronic equipment. Conducted disturbances refer to those that occur through the connecting cables or power lines, while radiated disturbances are emitted through the air. The standard also outlines test methods to verify compliance with these emission limits.

Testing and certification according to the IEC 61000-6-4 standard

In order to demonstrate compliance with the IEC 61000-6-4 standard, manufacturers of electrical and electronic equipment need to conduct thorough testing. This usually involves creating an appropriate test setup, measuring the emitted disturbances, and comparing the results to the specified limits. If the equipment passes the tests, it can be certified as compliant and carry the appropriate marking.

In conclusion, the IEC 61000-6-4 standard plays a crucial role in ensuring electromagnetic compatibility in industrial environments. By complying with this standard, manufacturers can minimize the risk of electromagnetic interference and ensure the reliable operation of their equipment. Testing and certification according to the IEC 61000-6-4 standard are essential steps towards achieving this goal.
