EMC Testing: What Is It and Why Is It Important?

Engineers want to test their product at least once for electromagnetic compatibility or EMC. This procedure uses a single set of standards and placing a mark on the product to allow them to be sold in various countries. For this reason, the merchandise or equipment must pass the EMC regulations of each country. Before manufacturers can think about selling their products in the local or international market, it is best that their products, especially if it is used in the health care industry, are properly tested for electromagnetic compatibility. But what exactly is EMC?

Understanding Electromagnetic Compatibility Test

One of the most important concerns of manufacturers when designing and using electronic products and devices is Electromagnetic Compatibility. EMC problems, especially in medical equipments, can lead to health hazards and life-threatening malfunctions. For this reason, there are rigorous requirements that the product must pass before it can be released into the market.

EMC testing means making sure that an electronic or electrical equipment of product must work as intended in a natural environment. The equipment must not generate or emit electromagnetic disturbances, which can affect and influence other devices. In a nutshell, EMC testing means dealing with the problems of noise emission and noise immunity of electronic and electrical devices.

EMC Can Ensure Product Reliability

It is essential to consider every aspect of EMC when building or designing an electrical device or installation. EMC testing is not only important in common devices, such as radios, television, and computers, but it is equally important when it comes to vehicles, machines, and other large industrial equipments and installations. This test can help limit the disturbance caused by the electromagnetic in every test. However, specific test modifications or higher requirements may be needed when testing for specific equipments.

Regulatory Compliance

Manufacturers who want to sell their equipments and devices outside the country must make sure that each of their products will pass the regulatory compliance of the country where they want to sell the equipment. The procedure may depend on the type of product.

    • Verification: The product is tested to EMC standards and introduced to the market with the appropriate regulatory marks or statements under the vendor’s authority.

    • Declaration of Conformity: The vendor must confirm that the product had passed the relevant standard. There are some countries that require the equipments and devices to be registered with regulatory marking and user information.

  • Certification: This is the test report from a certified and accredited recognized testing laboratory, along with the information about the product. The certification must be presented to the party who examines the requirements.
