Need help achieving IEC/EN certification? Schedule a free consultation with our team to discuss testing and achieving compliance for your product, or call us on 866-540-5287 to talk to our compliance experts right away.

As an electronics manufacturer, it’s important to make sure that your device complies with all of the industry standards and regulations for its type and purpose. 

One common standard that applies to electronic devices is IEC 61000-4-29 and its harmonized European standard EN 61000-4-29. As a part of the IEC 61000 series of standards, 61000-4-29 focuses on the immunity of DC powered electronic devices to voltage dips, variations and interruptions.

Achieving compliance with IEC 61000-4-29 is essential if you’re planning to sell your device in a region that requires this standard for market access. It’s also an important symbol of quality that signals your device is reliable in normal conditions.

As an accredited testing lab, we’ve helped hundreds of manufacturers achieve compliance with IEC 61000-4-29 and other important standards.

What is IEC/EN 61000-4-29?

IEC 61000-4-29 is a standard created by the International Electrotechnical Commission. It’s one of several parts of the IEC 61000 standards, which concern the electromagnetic compatibility, or EMC, of electrical devices and equipment. 

EMC refers to the ability of electronic devices to function together in a shared environment. For a device to comply with the IEC 61000 standards, it needs to demonstrate a necessary level of immunity to electromagnetic interference (EMI), as well as its own limited emissions. 

As a part of the IEC 61000 series of standards, IEC 61000-4-29 is designed to ensure that any electrical device can properly withstand and operate during and after disturbances in the direct current (DC) power supply. 

These disturbances can include brief reductions in voltage (voltage dips), short interruptions in power supply, and variations in voltage. 

As an accredited testing lab that offers IEC testing and compliance, we use a range of tests to check if your device complies with IEC 61000-4-29:

  • Voltage dips test. This test simulates conditions in which a device experiences a short reduction in voltage. Your device may be exposed to 30%, 60% or 90% reductions in its nominal voltage for a short period of time to assess its performance.
    This test assesses your device’s ability to maintain operation and recover after a voltage dip, showing that it can handle normal events that may affect non-compliance devices.
  • Short interruptions test. This test involves completely cutting off the power supply for your device for a brief period, while monitoring your device’s ability to continue working without malfunctioning or suffering damage.
    This test assesses how your device reacts to and recovers from brief interruptions in its power supply.
  • Voltage variations test. This test involves exposing your device to gradual changes in voltage levels, both voltage increases and decreases. This ensures that your device is capable of handling gradual variations in DC power supply without malfunctioning.

Why is IEC/EN 61000-4-29 Compliance Important? 

Achieving compliance with IEC/EN 61000-4-29 is important for numerous reasons, from product safety and reliability to ensuring you have access to major markets for electrical devices.

Product Reliability and Safety

Complying with IEC 61000-4-29 is important for ensuring your device is safe. Products that can withstand power disturbances are significantly less likely to fail in the field. This reduces the risk of your device causing safety issues and increases customer satisfaction.

Market Access and Competitiveness

Many countries require compliance with IEC 61000-4-29 or harmonized standards, such as EN 61000-4-29. Achieving compliance allows you to access these markets and demonstrates your product’s quality, increasing its competitiveness in the market. 

How to Achieve IEC/EN 61000-4-29 Compliance

Understand the Requirements of IEC/EN 61000-4-29

The first step towards achieving compliance with IEC 61000-4-29 is to understand the standard and its requirements. 

Our team can assist you in understanding IEC 61000-4-29 by explaining the types of electrical disturbances that need to be tested, the acceptable performance criteria, and the specific tests that your device will need to pass in order to achieve compliance with the standard.

Prepare Your Device for Testing

Before testing, you’ll need to prepare your equipment. This includes ensuring that your product is in a state that’s representative of its normal operating conditions, and that it is designed with the standard’s criteria in mind.

You may wish to conduct pre-testing to verify that your device functions as intended when it’s subjected to electrical disturbances and identify issues that may occur during the IEC testing process. 

Work With a Lab to Conduct IEC 61000-4-29 Compliance Testing

To verify that your device meets the IEC 61000-4-29 standard and achieve compliance, you’ll need to have your device tested by an accredited testing laboratory.

Our laboratory is accredited by ANSI, allowing us to offer testing for IEC, EN and many other standards and regulations. Our team of engineers can test your device using our specialized equipment and help you achieve and declare compliance.
