What is IEC TR 61000-4-19:2019?

IEC TR 61000-4-19:2019, also known as Electromagnetic compatibility (EMC) - Part 4-19: Testing and measurement techniques, is a technical standard published by the International Electrotechnical Commission (IEC). It provides guidelines and procedures for testing and measuring electromagnetic compatibility to ensure that electronic and electrical equipment operate effectively and reliably within their intended electromagnetic environments.

of IEC TR 61000-4-19:2019

This standard focuses on the measurement of immunity levels and violations of low-frequency magnetic fields. It specifies the test setup, test conditions, and test procedures necessary to evaluate the performance of equipment under various electromagnetic disturbances. The standard covers a wide range of frequencies and perturbation types, including power frequency magnetic fields, magnetic fields due to direct current, and magnetic fields from very low frequencies up to 100 kHz.

Testing Procedures and Requirements

IEC TR 61000-4-19:2019 outlines the necessary steps for conducting EMC tests and measurements. These include the preparation of test plans, establishment of test setups, execution of test procedures, and interpretation of test results. The standard also provides guidance on test environment considerations, such as the use of appropriate shielding and grounding techniques to minimize external disturbances during testing.

Furthermore, the standard specifies the required instrumentation and measurement techniques for evaluating immunity levels and verifying compliance with specified limits. It covers parameters like amplitude, duration, waveform shape, and frequency content of the magnetic fields being tested. Various test methods are described, including both qualitative and quantitative approaches, to determine the performance characteristics of equipment under different electromagnetic conditions.

Importance of Compliance

Compliance with IEC TR 61000-4-19:2019 is critical for manufacturers, suppliers, and users of electronic and electrical equipment. By following the guidelines provided in this standard, companies can ensure that their products are immune to common electromagnetic disturbances found in real-world operating environments. Compliance also helps reduce product failures, improve reliability, and enhance customer satisfaction.

In addition, adherence to this standard allows for better interoperability between different devices, as they are tested and designed to work harmoniously within shared electromagnetic environments. This is especially crucial in industries such as telecommunications, power systems, medical equipment, and aerospace, where multiple interconnected systems operate simultaneously.

IEC TR 61000-4-19:2019 serves as a valuable resource for engineers, researchers, and industry professionals involved in the design, testing, and deployment of electronic and electrical equipment. By adhering to its guidelines, the likelihood of compatibility issues and performance degradation due to electromagnetic disturbances can be significantly reduced, leading to increased operational efficiency and improved overall system performance.
