What is EN 61000-4-3:2012?

EN 61000-4-3:2012 is an international technical standard that deals with the testing and measurement of radiated radiofrequency (RF) electromagnetic fields, also known as electromagnetic compatibility (EMC). This standard specifies the requirements and test methods for electrical and electronic equipment to ensure proper functioning in the presence of RF disturbances.

Scope and Application

The scope of EN 61000-4-3:2012 covers a wide range of electronic devices, including industrial, scientific, medical, and residential equipment. It applies to both intentional and unintentional radiators, such as wireless communication devices, microwave ovens, and electronic medical equipment. The standard provides guidelines for testing equipment under various conditions and in different environments to determine their susceptibility or immunity towards RF interference.

Testing Methods and Procedures

EN 61000-4-3:2012 defines several testing methods and procedures to evaluate the performance of equipment under electromagnetic disturbances. These tests involve subjecting the equipment to calibrated RF fields at specific frequencies and power levels. The standard outlines the test setup, positioning of the equipment, and the criteria for evaluating the test results.

In addition to the radiated field tests, the standard also includes measurement techniques and test procedures for assessing conducted disturbances induced by RF fields.

Compliance and Certification

For manufacturers, compliance with EN 61000-4-3:2012 is crucial to ensure their products meet the required EMC standards. Compliance testing is typically performed in specialized laboratories using calibrated equipment and adhering to the standard's specific procedures. Once the equipment passes the tests, it can be certified as compliant, providing assurance to end-users regarding its reliability and interference-free operation.

Non-compliance with EN 61000-4-3:2012 can lead to degraded performance, malfunctions, or even complete failure when exposed to RF disturbances. It is therefore essential for manufacturers to adhere to the standard to ensure the quality and reliability of their products while conforming to regulatory requirements.
