Understanding EMC and Its Necessity

Today’s market has pushed a lot of business companies and manufacturers to introduce new products, equipments, and machines to the market faster and cheaper. However, these companies are still required to maintain high quality, durability, and reliability in each of the product they produce.One of the main concerns in designing and use of electrical and electronic products is complying with Electromagnetic Compatibility- or EMC. Products that are unable to comply with the requirements are at a higher risk of being recalled or stopped at customs which can have a negative effect on the product and company. Additionally, problems with the EMC can lead to potentially fatal malfunctions, especially in medical equipments. With that said, it is vital for each electrical and electronic goods to go through a rigorous and thorough EMC testing.EMC Testing: An OverviewElectromagnetic Compatibility is the inadvertent generation of electromagnetic energy between electronic devices and systems. It is also known as the interaction of electronic and electrical devices with its environment and other equipment. In simple terms, it means that the device must work as intended in its environment. It must not create electromagnetic disturbances that might influence other devices.EMC testing deals with the issues of noise emission and noise immunity of electrical and electronic devices and systems. Its primary goal is to determine the source of electromagnetic energy generated by a certain device to reduce potential interference to other equipment. This testing procedure also determines the product’s susceptibility from electromagnetic energy emitted from other devices near it.Why Is EMC Testing Necessary?In order to ensure that the products, equipments, and devices produced are safe and reliable, they must comply with EMC requirements. This is not only required for common devices, such as television sets, radios, and phones, but it is also necessary for complex equipment and machines, such as aircraft, vehicles, and ships. These equipments are very sensitive to electromagnetic compatibility problems. More importantly, no one wants to have a piece of device that can generate disturbances within a huge chemical plant.EMC testing is a long term investment since it ensures the product’s compliance with the important regulations and directives. Additionally, EMC testing also highlights any potential problems that a device has which must be fixed before production. After the device goes through a successful test procedure, manufacturers can be confident of their product’s safety and reliability. This will then result to lower warranty issues and repair costs, encouraging brand loyalty among its consumers.
