What is an EMC test?
Ensure problem-free operation with an EMC test
When bringing electronic products and components to the market, it's important that they coexist well with other electronic devices. This is also known as electromagnetic compatibility. In this blog, we'll provide answers to various questions about EMC testing, such as what an EMC test is and how electromagnetic compatibility works.
It's important for electronic devices and components to function in an electronic environment without causing disturbances to other devices. Additionally, the electronic device or system must also function properly without being influenced by other electronic devices. With an
EMC test,
you confirm that your devices meet electromagnetic compatibility criteria.
Electromagnetic compatibility
Almost all electronic devices generate some form of electromagnetic interference, which is unavoidable. But electromagnetic compatibility (EMC) is about controlling electromagnetic interference. There are certain limits set that an electronic device must comply with to prevent them from interfering with other devices. Effects of interfering with other devices can include component failure or unintended activation. In some situations, this can have serious consequences, such as in medical equipment or laboratory equipment.
Why is an EMC test important?
By conducting an EMC test, manufacturers and suppliers can demonstrate that their products meet EMC requirements. But what is an EMC test? An EMC test is a procedure conducted to determine if an electronic device complies with established standards. It primarily tests two aspects:
- Emission test: During the emission test, the amount of electromagnetic energy emitted by the device is measured. Emission levels must not exceed established standards. Emission tests assess both radiated (through the air) and conducted (via cabling) electromagnetic energy.
- Immunity test: In addition to testing the amount of electromagnetic emission, an EMC test also evaluates how well a device withstands external electromagnetic interference. The goal of the EMC directive is for the device to continue functioning normally when exposed to electronic fields.
Is an EMC test mandatory?
In some countries, conducting an EMC test is mandatory if you want to bring electronic equipment to the market. You must be able to demonstrate compliance with regulations to obtain product certification and avoid fines and legal issues. In all European Union countries, you must comply with the EMC Directive. Devices and installations with CE marking are freely tradable throughout the European Economic Area (EEA).
How to conduct an EMC test?
During an EMC test, a device is subjected to various conditions that may occur in practice. Having your electronic products tested by an accredited organization, such as DEKRA, contributes to the reliability and safety of an electronic product. DEKRA offers EMC facilities in the Netherlands, Germany, Spain, the USA, China, and Taiwan. We conduct EMC tests in our laboratories or at your location.
