What is IECTS 61000-6-4:2019?

IECTS 61000-6-4:2019 is an international standard that specifies the requirements for electromagnetic compatibility (EMC) of electrical and electronic equipment in industrial environments. This standard focuses on emission limits for conducted and radiated disturbances, as well as immunity requirements for electrical and electronic equipment.

Emission Limits

According to IECTS 61000-6-4:2019, electrical and electronic equipment should not produce electromagnetic disturbances that exceed certain limits. These limits are specified for different frequency ranges, such as radio-frequency range and fast transient/burst range. By complying with these limits, manufacturers can ensure that their equipment does not interfere with other devices in the industrial environment.

For example, in the radio-frequency range, the standard sets limits for both conducted and radiated emissions. Conducted emissions refer to disturbances that are transmitted through the power supply or signal cables, while radiated emissions refer to disturbances that are radiated through the air. Manufacturers need to ensure that their equipment stays within these limits to avoid causing interference with other electronic devices.

Immunity Requirements

In addition to emission limits, IECTS 61000-6-4:2019 also specifies immunity requirements for electrical and electronic equipment. Immunity refers to the ability of equipment to function properly in the presence of electromagnetic disturbances. The standard defines various test levels and performance criteria for different types of disturbances, such as electrostatic discharge, electromagnetic fields, and voltage dips and interruptions.

By subjecting their equipment to these immunity tests, manufacturers can ensure that their products can withstand common electrical disturbances encountered in industrial environments. This helps to minimize the risk of malfunctions or failures caused by external electromagnetic interference.

Compliance and Certification

IECTS 61000-6-4:2019 provides a framework for evaluating the EMC performance of electrical and electronic equipment in industrial environments. Manufacturers can test their products against the requirements specified in the standard to determine if they comply with the emission limits and immunity requirements.

Compliance with IECTS 61000-6-4:2019 is often mandatory in many countries, as it ensures that electrical and electronic equipment operates safely and reliably in industrial settings. Certification bodies evaluate products based on this standard and issue certificates to indicate compliance.

In conclusion, IECTS 61000-6-4:2019 is an important standard for achieving electromagnetic compatibility in industrial environments. By adhering to the emission limits and immunity requirements outlined in this standard, manufacturers can ensure that their equipment operates efficiently and does not cause interference with other devices. Compliance with this standard is essential for product safety and reliability in industrial sectors.
