What is IEC 61000-4-15:2019?

IEC 61000-4-15:2019 is an international standard that provides guidelines for testing and measuring flicker in electrical power systems. Flicker refers to rapid changes in light intensity, often caused by fluctuations in the voltage supply. These fluctuations can have adverse effects on people, especially those working with computer screens or performing visually demanding tasks.

The Importance of Flicker Testing

Flicker can cause discomfort, fatigue, and even induce seizures in individuals with certain medical conditions. Therefore, it is crucial to measure and control the amount of flicker present in electrical systems to ensure the safety and well-being of users. IEC 61000-4-15:2019 sets out specific procedures and requirements for carrying out flicker testing in a consistent and reliable manner.

Key Features of IEC 61000-4-15:2019

This standard outlines the methods for assessing flicker in both quantitative and qualitative terms. It provides guidance on measurement setups, test signals, instrumentation, and data analysis techniques. The standard also includes specific requirements for reporting and documenting flicker test results, ensuring transparency and traceability.

IEC 61000-4-15:2019 addresses various types of flicker, including short-term, long-term, continuous, and intermittent flicker. It provides different measurement techniques to accommodate different situations and devices. The standard also takes into account the frequency range over which flicker measurements should be performed, ensuring consistency across different electrical systems.

Benefits of Compliance with IEC 61000-4-15:2019

Compliance with IEC 61000-4-15:2019 not only ensures the safety of users but also benefits manufacturers and designers of electrical equipment. By following the guidelines provided in this standard, manufacturers can evaluate and improve the flicker performance of their products, enhancing customer satisfaction and market competitiveness.

Moreover, compliance with this standard allows for easier comparison of flicker test results between different laboratories and testing facilities worldwide. It promotes a common understanding and consistent assessment of flicker, facilitating global trade and collaboration in the electrical industry.
