What You Need to Know About EMC Testing

Are you new to EMC testing? If so, you need to be aware that it is a requirement for many different types of industries. Of course, you are probably wondering: why is EMC testing so important? The reason is because EMC testing helps you identify whether an electronic or electrical product you are manufacturing doesn’t have conducted or radiated emissions and the product is durable even in the face of a number of different electromagnetic situations. Here are some things you need to consider regarding EMC testing:

Regulatory bodies worldwide have their limits for the emissions these products can have.

The amount of electromagnetic spectrum we can use is not endless. It could run out, and the consequences would be disastrous. Thus, the first step in understanding more about EMC testing is to realize that even products such as radios, microwaves, x-ray machines and even products without transmitting components can emit this as a by-product. Protecting this finite resource is the only way to ensure all of the equipment that uses electrical components can function in the future.

EMC testing is also important for safety concerns.

Without EMC testing, many electronic devices would emit too many watts and it would not only cause the equipment to go down, but it would also overwhelm nearby electrical areas as well. In the case of a bunch of cell phones transmitting data on an airplane or with high-tech medical devices, this could literally mean the difference between life and death.

EMC testing is not a new rule.

Understanding more about EMC testing also requires knowing a bit about their history. EMC testing has been around in some shape or form for a very long time. In 1899, one of the first laws regarding this type of testing was passed. Many London residents were noticing that lights were flickering when there were too many defective electric lamps. Since the power grid was just getting started in London at the time, it was then that their parliament decided to pass the “Lightning Clauses Act.”

We have come a long way since then in understanding how electrical components can negatively affect one another. However, this technology will continue to evolve, and it is up to you to stay up to date on all of the latest requirements.
