What is IEC 61000-4-15:2019?

The International Electrotechnical Commission (IEC) is a global organization that develops and publishes standards for electrical equipment and technologies. One of the widely recognized standards in the field of electromagnetic compatibility (EMC) is IEC 61000-4-15:2019. This standard provides guidelines and test procedures to assess the immunity of electrical and electronic devices against voltage fluctuations and flicker.

Understanding Flicker

Flicker refers to rapid changes in light intensity perceived by the human eye. It occurs when the electric voltage supplied to lighting sources fluctuates. This fluctuation can be caused by various factors such as power grid disturbances or the switching on/off of large electrical loads. Flicker can be annoying and may even lead to health issues for sensitive individuals. Therefore, it is important to measure and control flicker to ensure comfortable and safe lighting conditions.

Key Elements of IEC 61000-4-15:2019

IEC 61000-4-15:2019 defines the measurement methods and limits for evaluating voltage fluctuations and flicker caused by external sources. The standard specifies specific parameters to quantify the severity of flicker, including short-term flicker severity (Pst) and long-term flicker severity (Plt).

Pst is calculated based on the voltage variations occurring within a ten-minute period, whereas Plt considers variations happening throughout an extended period. Both Pst and Plt are expressed as a percentage, and there are respective thresholds provided in the standard to determine acceptable levels of flicker.

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

Complying with IEC 61000-4-15:2019 brings several advantages for manufacturers and users of electrical and electronic devices. Firstly, it ensures that products meet minimum quality standards and are not susceptible to voltage fluctuations and flicker issues. This improves the performance and reliability of the devices, leading to enhanced customer satisfaction.

Furthermore, adherence to the standard allows for better harmonization in international trade, as products meeting IEC requirements gain wider acceptance and trust. Compliance also helps in reducing potential legal liabilities and product recalls. Overall, IEC 61000-4-15:2019 provides a common framework and language for addressing flicker-related problems in a systematic and standardized manner.

In conclusion, IEC 61000-4-15:2019 is an essential standard that provides guidelines for assessing and managing voltage fluctuations and flicker in electrical and electronic devices. By following this standard, stakeholders can ensure that their products meet quality expectations and adhere to international regulations, leading to improved product performance and customer satisfaction.
