Electronics and technology practically rule the lives of most of the people in the world. However, nobody really considers what goes into making sure an electronic device or product can get onto the selling shelf and into your hands. There are many different procedures and processes that electronic devices have to go through before they get into the pocket of the consumer. Here are three types of conformance tests that electronic devices must pass before going on sale.
The Emission Test
Emission tests are designed to make sure that each product will not emit any sort of harmful electromagnetic interference during its use. This not only includes the use of the actual product but it includes the use of power lines and the improvement of communication. Emission tests can even be broken down into a few different categories such as radiating and conducting emissions. Using near field probes, the different levels of electromagnetism are measured with input and output.
The Immunity Test
A radiated immunity testing does just what it says—it makes sure the products are immune. In the environments that electronic devices are typically used, such as a radio station, or other products in the area may emit electromagnetic interference. Immunity testing makes sure the products are immune from being damaged by all of those incoming signals and interference.
The Safety Test
Safety tests are some of the most important as they make sure the product is safe from any sort of malfunctioning danger. Most safety tests are typically ran to ensure that the products do not create any danger or risk from a failed or shorted power supply, a cooling vent that may be blocked (to cause overheating) or even dips and spikes in power line voltage.
As you can see, the process to make sure that electronic devices are safe and efficient is sometimes a complicated one. There are many tests that each thing must go through before it becomes user-ready, and it is good to know about each one. Think about this long process the next time you pick up your cell phone or search the web on your computer.
