What Is Electromagnetic Compatibility Testing or EMC Testing?

Let’s begin with the basic definition: So the capacity of the equipment to operate properly in its electromagnetic surroundings without contributing excessive electromagnetic disruption to anything in that surroundings is measured by electromagnetic compatibility testing or EMC testing.

So, we can precisely say that EMC testing enables you to confirm that your electrical or electronic item does not generate electromagnetic interference and that it performs as envisaged in the presence of different electromagnetic factors.

Types of EMC Testing 

Electromagnetic Compatibility Testing is of two types:

  1. Immunity Testing
  2. Emissions Testing

Let’s discuss both briefly:

1. Immunity Testing

It assesses how a device responds to electromagnetic distortion and other disturbances. The goal of these tests is to gain rational assurance that the device will function as designed when used in its predicted operating environment.

2. Emissions Testing

It determines the quantity of electromagnetic noise produced by a device while it is in normal operation. The goal of these tests is to ensure that any emissions produced by the device are below the relevant limits established for that type of device. As a result, there is a reasonable expectation that the device will not end up causing interference problems to other devices functioning within its predicted operating environment.

Why Is EMC Testing Necessary?

EMC Testing or ElectroMagnetic Compatibility Testing exists to make certain that your electronic or electrical gadget does not emit a significant amount of electromagnetic interference (known as radiated and carried emissions) and that it keeps going to function as intended in the presence of a variety of electromagnetic phenomena. Regulatory bodies all over the world have set limits on the amount of pollution that electronic and electrical products can emit.

You should further note that electromagnetic immunity testing is required in some areas and for certain product types. Moreover, it is essential to bring a new product to the market.

Approved Method To Perform EMC Testing: How To Reduce The Risk? 

You need to keep in mind that as per the approved method of testing, the EMC testing procedure incorporates three different steps that are:

1. Emission Test 

Emission is the intentional or unintentional production of electromagnetic energy by any supplier. EMC tests for electronic devices are configured to check for undesirable emissions from the device as well as countermeasures that could be taken to lessen and protect them from adversely affecting other devices around it.

Emission testing entails measuring the undertaken and radiated field strength of emissions in the device, with undertaken emissions evaluated along with cables and circuits and radiated emissions evaluated in all directions around the device.

2. Susceptibility Test

Susceptibility refers to the propensity of one piece of an electrical device (usually referred to as the victim) to fail or malfunction when exposed to emissions from another device (EMI). Susceptibility testing, like emissions testing, is performed for both radiated and conducted interventions.

Radiated susceptibility testing typically employs a high-powered origin of electromagnetic radiation and a radiating antenna to guide the energy to the DUT (device under test). Conducted susceptibility testing, on the other hand, is typically performed using high-powered signal generators in conjunction with a current clamp or another type of transformer to inject interference on the cable.

3. Immunity Testing

An electronic device’s immunity refers to its potential to function properly in the presence of electromagnetic disturbance.

While immunity is the reverse of susceptibility by definition, the terms are frequently used interchangeably. And by evaluating their levels, the ability of the electronic device to function properly in the presence of EM Interference can be validated. ​​

What Are The Legalities Related To EMC Testing? 

Several worldwide, national, or regional agencies define EMC standards. There are international standards that are established by organizations like the Institute of Electrical and Electronics Engineers (IEEE) or the International Electrotechnical Commission (IEC) (IEEE). Some nations have national organizations like the VDE in Germany, BIS in India, the Canadian Standards Association in Canada, and the FCC in the United States that set their own standards.

Increased emissions in the form of EMI/RFI and other fallacious signals generated in part by sophisticated equipment/ components and radiated by interconnecting cables may cause malfunctions in televisions, radios, computers, aviation communications, medical equipment, and other electronic devices. This is why in the majority of countries, product testing for EMI regulations is required.

All products must be built in such a way that they do not cause interference, particularly with radio and telecommunications equipment. Additionally, equipment must have an intrinsic immunity level to electromagnetic disturbances, allowing it to operate as intended.

The potential of an individual product to meet EMC requirements can be validated by testing the product against established standards at our Laboratories.
