EMC Testing & Certification
What is EMC Testing?
EMC refers to Electro Magnetic Compatibility and Electro Magnetic Interference between Electrical products and the implication on the end user in terms of Emission on the user and Immunity from hazardous. Therefore, EMC testing & certification are mandatory requirements worldwide and essential in product design.
EMC compliance testing is important to getting your electronic product ready for market. Industry veterans understand that electronic devices can be plagued by signal interference and equipment emissions. That’s why electromagnetic compatibility (EMC) is mandatory worldwide before launching a product. At 360 Compliance, we handle every single aspect of your EMC testing.

What are the Different Types of EMC Testing?
There are two main types of EMC testing:
- Emissions Testing: This phase measures the electromagnetic radiation emitted by a device. Uncontrolled emissions can interfere with other nearby electronic equipment or even compromise the device’s own performance. Emissions testing ensures that devices operate within specified limits to prevent such interference.
- Susceptibility Testing: Also known as immunity testing, this assesses how well a device can withstand external electromagnetic interference (EMI) without malfunctioning. Devices are subjected to various electromagnetic fields to determine their resilience in real-world scenarios.
The EMC Testing Procedure
The specific procedure can vary depending on the device and the applicable standards, but here’s a general overview:
1. Pre-testing preparation:
- Identify applicable standards: Different regulations exist for various devices and markets (e.g., FCC in the US, CE in Europe).
- Develop a test plan: This outlines the specific tests to be conducted and the equipment needed.
- Prepare the Device Under Test (DUT): This could involve setting up the device in its intended operating configuration with cables, antennas, and peripherals.
2. Emissions testing:
- Measure the electromagnetic waves emitted by the DUT using specialized antennas and receivers in an anechoic chamber (a shielded room that absorbs reflections).
- Compare the measured emissions to the limits specified in the relevant standards. If the emissions exceed the limits, the device fails the test.
3. Immunity testing:
- Expose the DUT to various electromagnetic fields, simulating real-world scenarios like electrostatic discharges, power surges, and radio frequency interference.
- Observe the DUT’s performance under these conditions. If the device malfunctions or exhibits unexpected behavior, it fails the test.
4. Reporting and certification:
- Test report: Compile a detailed report documenting the testing procedures, results, and conclusions.
- Certification: If the DUT passes all tests, it can be certified as compliant with the relevant standards.
What Types Of Products Need EMC Certification?
Any electronic device can benefit from EMC testing, but certain categories require it due to their potential impact on other electronics or their own susceptibility to interference. Here are some key examples, along with the relevant standards they should comply with:
- Televisions: Can emit strong radio frequencies that interfere with other devices like radio receivers. Standard: CISPR 32
- Smartphones and tablets: Wireless communication and internal circuitry can both emit and be sensitive to interference. Standard: FCC Part 15
- Bluetooth speakers and headphones: Continuous data transmission can lead to EMI issues if not properly designed. Standard: EN 55032
- Home appliances: Microwave ovens, washing machines, and refrigerators can generate electromagnetic noise, affecting other devices. Standards: EN 55014
Additionally, EN 55032 is a specific product standard covering EMC compliance testing of Multimedia Equipment (MME) and replaces several other product standards, including EN 55022 for ITE. You can find more detailed guidance on EN 55032 here.
- Motors and drives: High currents and switching frequencies can create conducted and radiated EMI, disrupting control systems and communication in factories. Standards: EN 61800-3, IEC 60034-5
- Robots and automated machines: Wireless communication and control signals can be susceptible to interference, impacting operation and safety. Standards: EN 55011, IEC 61000-6-4
- Medical devices: Ensuring their proper functioning despite potential EMI from other equipment is crucial for patient safety. Standard: IEC 60601-1-2
- Automotive electronics: From GPS systems to engine control units, car electronics need to be EMI-resistant and not interfere with other vehicles or roadside infrastructure.
- Wireless access points and routers: These devices constantly transmit and receive data, so compatibility with other Wi-Fi signals is essential.
- Some toys and hobby equipment: Depending on their functionality and emissions, specific types of toys and hobby products might also require EMC testing.
