What is BS EN 55016-2-4:2016?

BS EN 55016-2-4:2016 is a technical standard that specifically addresses the measurement of radio frequency disturbance power in audio, video and audio-video equipment. It provides guidelines for electromagnetic compatibility (EMC) testing in these types of devices, ensuring their permissible levels of disturbance emissions are within regulated limits.

Scope and Purpose

The scope of BS EN 55016-2-4:2016 is to define the methods and specifications for measuring conducted disturbances in the frequency range of 9 kHz to 400 GHz. This standard applies to both intentional radiators and unintentional radiators used in audio, video and audio-video equipment.

The purpose of this standard is to establish a common framework for manufacturers, test laboratories, and regulatory bodies to evaluate and compare the performance of different products in terms of electromagnetic compatibility. By adhering to this standard, equipment manufacturers can ensure that their products meet the necessary regulatory requirements and do not cause interference with other electrical devices.

Testing Methods

The standard specifies the test conditions under which measurements should be made, including the setup of the equipment, the distance between the device under test (DUT) and the measuring apparatus, and the procedures for conducting the tests.

One of the key parameters evaluated is the conducted disturbance voltage or current emitted by the DUT. This is measured using specialized equipment, such as line impedance stabilization networks (LISNs) and spectrum analyzers, which capture the emitted signals and analyze them across the required frequency bands.

Compliance and Certification

Meeting the requirements outlined in BS EN 55016-2-4:2016 is essential for manufacturers to obtain certification and comply with relevant regulations in many countries. By undergoing EMC testing according to this standard, manufacturers can ensure that their products meet the necessary levels of electromagnetic compatibility and do not interfere with other electrical devices.

Furthermore, compliance with this standard is also crucial for ensuring optimal performance and safety of audio, video and audio-video equipment. By reducing disturbance emissions, manufacturers can minimize potential interference issues and guarantee reliable operation of their products.
