What is the IEC 61000-4-6 Criteria?

The IEC 61000-4-6 criteria, also known as CISPR 16-1-2, is an international standard that provides guidelines for the testing and measurement of radiated emissions in the frequency range of 9kHz to 3GHz. This standard is applicable to equipment used in various industries, such as telecommunications, information technology, and consumer electronics.

Background

In today's world, electronic devices have become an integral part of our daily lives. From smartphones to laptops, from televisions to kitchen appliances, these devices emit electromagnetic radiation during their operation. While this radiation is usually within safe limits, it can sometimes interfere with other nearby electronic equipment or cause disturbances in the electromagnetic environment. This is where the IEC 61000-4-6 criteria come into play. It provides a framework for manufacturers to ensure that their equipment meets the necessary emission limits and does not cause any interference in its intended operating environment.

Testing Methodology

The IEC 61000-4-6 criteria outline the procedures and requirements for conducting radiated emission tests. These tests are typically performed in an anechoic chamber to minimize external influences. The equipment under test is subjected to a range of radio frequencies, and measurements are taken at specific distances from the device. These measurements help determine the level of radiated emissions generated by the equipment and whether they comply with the specified limits.

Compliance and Certification

Compliance with the IEC 61000-4-6 criteria is crucial for manufacturers looking to market their products globally. By adhering to these standards, companies ensure that their equipment is compatible with other devices and environments, reducing the risk of interference and improving overall electromagnetic compatibility.

In conclusion, the IEC 61000-4-6 criteria provide a standardized approach to testing and measuring radiated emissions. By following these guidelines, manufacturers can ensure that their electronic equipment meets the necessary requirements and does not cause any disruptions in its operating environment. This standard plays a vital role in creating a harmonious electromagnetic environment, allowing various electronic devices to coexist without interference.
