What is IEC 61000-6-4 and EN 61000-6-4?

The IEC 61000-6-4 and EN 61000-6-4 are international and European standards respectively, which define the requirements and test methods for electromagnetic compatibility (EMC) in industrial environments. These standards specifically address the emissions of electrical and electronic equipment when subjected to a range of electromagnetic disturbances such as radiofrequency interference (RFI).

Understanding the Scope and Application

The IEC 61000-6-4 and EN 61000-6-4 standards apply to all electrical and electronic equipment intended for use in industrial environments, including machinery, control systems, measurement and laboratory instruments, computers, communication equipment, and more. Industrial environments typically involve high-power electrical systems, where various devices coexist and operate simultaneously. The purpose of these standards is to ensure that such equipment can function properly without causing interference or disruptions to other nearby equipment.

Requirements and Testing Methods

IEC 61000-6-4 and EN 61000-6-4 specify both immunity and emissions requirements for industrial electrical equipment. Immunity requirements relate to a device's ability to withstand electromagnetic disturbances without experiencing malfunctions or performance degradation. Emissions requirements, on the other hand, limit the amount of electromagnetic radiation that a device can emit, so as not to interfere with other equipment in its vicinity. The standards also provide guidance on how to measure and determine compliance with these requirements through specific test methods and procedures.

Benefits of Compliance

Compliance with IEC 61000-6-4 and EN 61000-6-4 brings several benefits to manufacturers and users of industrial equipment. By meeting these standards, manufacturers can ensure that their products are less likely to cause disruptions or malfunctions in the presence of other devices. This ultimately leads to improved product reliability and customer satisfaction. For end-users, compliance means that the equipment they purchase will operate effectively in industrial environments without negatively impacting nearby equipment or compromising safety. Compliant equipment is also more likely to meet legal and regulatory requirements, thereby avoiding potential penalties or restrictions.
