Electromagnetic Compatibility (EMC) Type Approval and Certification

In today’s digital era, the use of radio frequency devices, such as WiFi signal boosters, RFID, and the Internet of Things (IoT), is becoming increasingly widespread. Because these devices operate in close proximity, they can interfere with each other if they do not comply with appropriate technical standards.

This is where Electromagnetic Compatibility (EMC) type approval and certification are essential. The primary goal is to prevent electromagnetic interference that could compromise device performance and user safety.

To market electronic products globally, manufacturers must secure EMC type approval and certification. Obtaining this compliance access ensures that a product can operate optimally without disrupting other devices while meeting internationally recognized safety standards.

What Is EMC?

Electromagnetic Compatibility (EMC) is the ability of an electronic device to function properly in an electromagnetic environment. This means that the device does not cause or experience interference from other devices.

EMC testing covers two main aspects, namely electromagnetic emissions and resistance to electromagnetic interference. Electromagnetic emissions are measured to determine how much electromagnetic interference the device emits into the surrounding environment. In addition, the device’s resistance to electromagnetic interference from other devices is also measured.

Electronic products that do not undergo EMC type approval and certification may experience signal interference, performance degradation, and malfunction. There may even be dangerous safety risks, which could harm users.

International EMC Regulations and Standards

EMC approval and certification are processes that manufacturers must undergo to meet the mandatory legal requirements for access to global markets. The goal is to ensure that devices do not emit electromagnetic waves that could interfere with other telecommunications devices.

Each country has its own national EMC compliance requirements, which generally refer to CE or FCC standards. The underlying technical limits have largely been harmonized through international standards organizations such as the IEC, CISPR, and ISO.

In the ASEAN region, EMC regulations are governed nationally by each country, with efforts to harmonize standards through Mutual Recognition Agreements (MRAs). The goal, of course, is to expedite the distribution of products in the regional market. This measure is particularly helpful for manufacturers targeting cross-border exports in Southeast Asia.

EMC Testing Process

To obtain EMC type approval and certification, it is generally necessary to undergo radiated and conducted emission testing. Emission testing is generally conducted in the frequency range of 150 kHz to 30 MHz. In this frequency range, it must be ensured that electronic devices do not interfere with other devices in their vicinity.

Radiated emissions tests

Radiated emissions tests are a process of measuring the amount of electromagnetic waves that are unintentionally emitted by electronic devices. Excessive emissions will cause interference with other equipment.

The testing process uses an EMI receiver and a signal-measuring antenna. The device will be tested in an anechoic chamber or an open space. To detect emissions from various angles, the sample is placed on a remotely controlled turntable.

Conducted emission tests

Conducted emissions tests are the process of measuring electromagnetic interference emitted through the device’s power or signal cables. This interference risks disrupting other devices connected to the same power source.

The testing process uses an EMI receiver and an artificial mains network (AMN). Emission levels are measured in the range of 150 kHz to 30 MHz. The test results are compared with applicable EMC standard limits.

Strategic Value of EMC Certification

Type approval is more than just an administrative requirement. You need to view it as a business strategy. Completing this process provides benefits that directly impact your goals for marketing your products globally:

• Smooth access to international markets
• Elimination of potential delays at customs and import restrictions
• Prevention of product recalls for items ready for import or already on the market
• Proven product safety and reliability
• Increased customer trust

By prioritizing compliance, manufacturers will immediately gain a competitive advantage. This allows them to deliver stable, market-ready products worldwide.
