What is IEC TS 61000-5-6:2019?

IEC TS 61000-5-6:2019 is a technical specification published by the International Electrotechnical Commission (IEC) that provides guidelines for the design and testing of electromagnetic compatibility (EMC) in low-voltage electrical and electronic equipment. This standard specifically addresses the immunity of equipment to conducted disturbances induced by radio-frequency fields.

Purpose and Scope

The purpose of IEC TS 61000-5-6:2019 is to provide manufacturers, designers, and test laboratories with a standardized method for assessing the immunity performance of their products against RF disturbances. It ensures that equipment can operate without degradation when exposed to conducted disturbances in the RF frequency range.

This technical specification applies to all electrical and electronic equipment within its scope, regardless of their function or application. It focuses on the immunity requirements and test methods for three defined categories of electrical and electronic equipment defined in IEC 61000-5-1 - industrial, scientific, and medical (ISM), information technology equipment (ITE), and audio/video equipment and broadcasting receivers.

Key Requirements

IEC TS 61000-5-6:2019 specifies the basic EMC immunity requirements for equipment under test (EUT) by defining the test levels and methods required to evaluate their performance. The standard outlines various conducted test setups and procedures using either continuous wave (CW) signals or modulated disturbances.

The test levels are based on the EN 55016 series of standards, which defines the measurement procedures for the determination of disturbance power. These levels are defined for each of the applicable frequency bands and depend on the environment in which the equipment will be used. The standard also specifies the performance criteria and defines the assessment and verification procedures.

Conclusion

IEC TS 61000-5-6:2019 plays a crucial role in ensuring the electromagnetic compatibility of electrical and electronic equipment. By providing guidelines for assessing immunity against RF disturbances, this technical specification helps manufacturers achieve reliable operation of their equipment in various environments. Compliance with this standard ensures that products do not malfunction or cause interference when exposed to conducted disturbances induced by radio-frequency fields, thereby enhancing overall product quality and customer satisfaction.
