What is BS EN55016-3-1:2016?

In today's rapidly advancing world of technology, electromagnetic compatibility (EMC) plays a critical role in ensuring the proper functioning of electronic devices. The International Electrotechnical Commission (IEC) sets guidelines and standards to regulate EMC, and one such standard is BS EN55016-3-1:2016. This article will provide an in-depth technical of this important standard.

Understanding EMC Compliance

Electromagnetic compatibility is the ability of an electronic device to coexist with other devices in its electromagnetic environment without interference or disturbance. Non-compliant devices can emit electromagnetic radiation that affects the performance of other devices, leading to malfunctions or even safety risks. BS EN55016-3-1:2016 sets out specific measures and test procedures for assessing radiated and conducted emissions from equipment operating in a frequency range between 9 kHz and 18 GHz.

Main Requirements of BS EN55016-3-1:2016

BS EN55016-3-1:2016 outlines the measurement methods and limits for various categories of electrical and electronic equipment. These requirements are crucial to ensure that the equipment complies with the acceptable levels of electromagnetic emission. The standard covers emissions during normal operation as well as exceptional conditions, such as fault conditions or abnormal environmental influences.

Testing Procedures under BS EN55016-3-1:2016

To ensure compliance with the standard, testing procedures must be followed. The standard provides detailed instructions on how to set up the test equipment, perform the measurements, and interpret the results. It also specifies the necessary instruments and calibration requirements for accurate testing.

During testing, emissions are measured at various points on the equipment under test. This includes measuring radiated and conducted emissions in different frequency ranges. The standard also details the use of specialized antennas, receivers, and spectrum analyzers for accurate measurements.


BS EN55016-3-1:2016 is an essential standard for ensuring electromagnetic compatibility in electrical and electronic devices. Compliance with this standard is crucial to prevent interference and ensure reliable operation of equipment. Understanding the main requirements and testing procedures outlined in BS EN55016-3-1:2016 is important for manufacturers and regulatory bodies to maintain a high level of EMC compliance in today's technology-driven world.
