What is IEC 61000-4-15:2019?

The International Electrotechnical Commission (IEC) is a global organization that develops and publishes standards for electrical technologies. One of the important standards in this field is IEC 61000-4-15:2019, which deals with flicker measurement. Flicker refers to the perceptible changes in brightness of a light source, and it can cause visual discomfort or even trigger epileptic seizures in some individuals. This article provides an of IEC 61000-4-15:2019 and its significance in ensuring the safety and performance of electrical devices.

Understanding Flicker

Flicker is a common issue in many lighting systems, including incandescent bulbs, fluorescent lights, and LED lights. The human eye is sensitive to rapid changes in brightness, and when the frequency of fluctuations exceeds a certain threshold, it becomes visible as flicker. Flicker is particularly problematic in applications where visual comfort is important, such as in offices, schools, and healthcare facilities. To address this issue, IEC 61000-4-15:2019 provides guidelines and requirements for measuring and evaluating flicker in electrical devices.

Measurement Methodology

IEC 61000-4-15:2019 outlines a standardized measurement methodology for assessing flicker in electrical devices. The standard defines various parameters and procedures to determine flicker severity quantitatively. It specifies the use of specific equipment and measurement techniques to accurately evaluate the flicker characteristics of different light sources. By following these guidelines, manufacturers can ensure that their products comply with the recommended limits and deliver adequate visual comfort to users.

Importance of Compliance

Compliance with IEC 61000-4-15:2019 is crucial for manufacturers and designers of electrical devices. Adhering to the standard's requirements helps ensure that products are safe, reliable, and visually comfortable for end-users. By testing and validating their devices according to the specified measurement methods, manufacturers can identify any potential flicker issues in advance and take corrective actions. Moreover, compliance with the standard allows for harmonization and compatibility between different devices, facilitating interoperability and seamless operation in various lighting installations.
