What is EMI/EMC testing and why it is necessary?

EMC (Electromagnetic Compatibility) pertains to enabling a device to function properly in its intended environment in the presence of EMI sources. Testing is essential to determine that a device can operate within its intended environment and in accordance with required standards.

What are the scopes of EMI/EMC testing?

What is the Scope of EMC / EMI Testing ? EMC / EMI testing is broken down into two categories. Testing for emissions ( Electromagnetic Interference , or EMI ), and testing for immunity . Devices must not interfere with the safe operation of other electronic devices by producing Electromagnetic Interference .

What does EMC stand for and what does it do?

What does EMC stand for? EMC. By Vangie Beal Short for Electromagnetic Compatibility, EMC is the term used to describe how well a device or system is able to function in an electromagnetic environment without introducing electromagnetic disturbances that interfere with the operation of other electrical products in the environment.

What is electromagnetic compatibility (EMC) and why testing is necessary?

Electromagnetic compatibility testing is necessary to help you meet regulatory requirements, improve product performance and reduce the risk of costly non-compliance. A third-party EMC test lab can conduct conformity assessments and also help to strengthen your competitive position in the market.

What requires EMC testing?

The FDA requires that all medical devices undergo EMC testing per the appropriate FDA Reviewer Guidance document or the European IEC 60601-1-2 standards. In the EU, all medical devices must have CE marking, which requires both immunity and emissions testing per IEC 60601-1-2.

Why do you need an EMC test?

EMC (ElectroMagnetic Compatibility) testing exists to ensure that your electronic or electrical device doesn't emit a large amount of electromagnetic interference (known as radiated and conducted emissions) and that your device continues to function as intended in the presence of several electromagnetic phenomena.

What is the purpose of EMC standards?

EMC standards specify the acceptable limit of EMI in any electrical or electronic system. EMC standards ensure that a device's operation does not disturb the communication system around it or the devices adjacent to it.

Is EMC required for CE?

EMC Testing requirements Most electrical and electronic equipment sold in the EU must be CE marked. So they need compliance with the EMC Directive “Electromagnetic Compatibility, 2014/30/EU” (replacing 2004/108/EC). This can be achieved by identifying and applying the most relevant product standard.

What are the three elements of EMC?

There are three essential elements to an EMC problem as illustrated in Figure 1. There must be a source of electromagnetic energy, a receptor (or victim) that cannot function properly due to the electromagnetic energy, and a path between them that couples the energy from the source to the receptor.

What is EMC testing for medical devices?

An electromagnetic compatibility (EMC) test ensures that electronics and electrical devices do not emit large amounts of electromagnetic interference, such as radiated or conducted emissions, and ensure that the device functions as originally intended.

What is EMC risk?

Electromagnetic interference (EMI) can be a cause of unreliability in all electronic technologies, so electromagnetic compatibility(EMC) must be taken into account when the risks caused by malfunctioning electronics are to be controlled.

What are EMC issues?

An EMC problem (or Electromagnetic compatibility problem) occurs when one piece of electronic equipment or an electromagnetic system is adversely affected by the operation of another. One example might be breakthrough by the high field strengths produced by a nearby radio transmitter.

Is EMC the same as CE?

Electromagnetic Compatibility (EMC) Testing Meeting the requirements of the Electromagnetic Compatibility (EMC) Directive, 2014/30/EU, is an essential part of the CE Marking process. EMC ensures that an electronic product does not adversely affect, or be affected by other products in the same environment.

Can I sell without CE?

If a product that needs CE marking doesn't meet the relevant requirements, it cannot be sold legally in the participating countries.

Can you sell products without CE?

Products can be withdrawn from the market and penalties can be imposed. Manufacturers, importers and/or authorised representatives will be held liable if the CE mark has been fixed illegally or if the product does not meet the standards indicated by the EU harmonised standards.

What are the advantages of EMC standards?

Early EMC testing can save money by reducing overengineering, so ensuring that a product can pass compliance tests easily. Before a product is tested it is not known where the problems might occur. This can lead to counter-measures being added where they are not required.

What are the advantages of EMC?

The main goal of EMC is to ensure that electronic circuits operate correctly when exposed to external EM radiation, and to ensure that the electronic circuit in question does not emit “stray” EM radiation.

What is EMC Testing?

The FCC defines a variety of tests to make sure that any electronic devices on the American market adhere to the EMC requirements. These tests allow regulatory bodies to be certain that your products are safe and suitable for their intended environment, either commercial/industrial or residential. EMC compliance is a serious matter, and it’s not legal to take an electronic product to market without first securing approval by clearing the tests laid down by the FCC.

What is electromagnetic compatibility?

First of all, electromagnetic compatibility is the wider field of ensuring that devices are able to coexist in a shared electronic environment. If you operate virtually any electronic device, it will produce radiofrequency radiation that can interfere with the operation of other devices.

What devices use radiofrequency waves?

In some cases, these are intentional radiators that use radiofrequency waves for communication purposes with other devices, such as LTE, 5G cellular phones, IoT, IIoT devices and laptops.

Does the FCC administer tests?

The FCC doesn’t administrate tests on its own; rather, it certifies a variety of laboratories around the country that are capable of performing the tests. Once you find a suitable laboratory, you’ll need to provide a working model of the device and handle various paperwork-oriented tasks. However, the majority of the work falls to the lab. If you pass their tests, you’ll be able to move to market with your device. On the other hand, failing the tests will prohibit you from doing so until you fix the problems that the laboratory diagnosed.

Can all devices put out electromagnetic interference?

Without these standards, it would be possible for a few devices to put out high levels of electromagnetic interference (EMI) that interfere with the operation of the rest. However, even with regulations, all devices put out some amount of EMI. As such, regulatory bodies also define complementary standards for electromagnetic compatibility (EMC).

How to reduce the cost of EMC testing?

Another way of reducing cost and the possibility of failing the test is to perform EMC testing throughout the design process using an EMC Pre-Compliance testing setup that is tailored towards the conditions that will be used during the compliance testing. While it may cost you just a little less than what you might pay for a day with an accredited lab, it will increase the chances of the device passing the test on the first try, lower the overall test cost, and reduce your time to market.

Why is EMC certification important?

EMC Certification helps increase product reliability as the tests would help highlight any potential issues with the product before production, giving the manufacturer the opportunity to fix the problem without incurring the costs and embarrassment associated with recalling a product from the market or servicing warranties.

What is EMI certification?

As mentioned in the last article where we discussed Electromagnetic Interference (EMI), almost all electronic products designed for commercial use and legal sales, are required to possess one or more certifications as a proof that the product complies with certain regulations/guidelines and has passed related tests. There are tonnes of regulations and they differ from place to place, sometimes with minor differences, but for every location where an electronic device is to be sold, it must meet the standards specified by the governing body in that location.
