This interference is then noted and further tests are performed.Īs we briefly stated earlier, each product will need to meet specific EMC levels before it can be released to the market and sold. switching a device on or turning it off). These tests are performed at different stages of typical use to find where, if any, potential spikes may occur (i.e. It is a test or series of tests that are carried out to see how an electrical product interacts with other electrical devices. With the proliferation of electronic devices into everyday life – TVs, washing machines, electronic ignitions, traffic lights, mobile phones, ATMs, anti-theft tags, to name but a few, there is huge potential for devices to interfere with each other.ĮMC Testing is simply that. All electronic devices have the potential to emit electromagnetic fields. SO, WHAT EXACTLY IS INVOLVED IN EMC TESTING?Įlectromagnetic Compatibility, also known as EMC, is the interaction of electronic equipment with both the electromagnetic environment and with other equipment. The importance of EMC testing varies depending on the product and the industry, with each having different guidelines and standards that they must meet. In defence, one of the more common of these tests is EMC which checks on how the equipment interacts or interferes with other electronics. If you manufacture electronics, it doesn’t matter whether it is an electric shaver or a computer, before being able to bring it to market there are several tests that it has to pass.
