Standards and tests are needed everywhere in the world. When the communication business starts and many companies appear, it is clear that some types of rules need to be applied to regulate how this field works, so that in this case CE testing is made.
Today's technology in the future moves and world innovation is brought to this field every year. There is also the fact that technology is also commercial, so to protect all CE certification customers are made. It states that a company requires CE testing to prove the fact that technology works and clients are safe to use it. You can consider the product safety marking to approve the products to sell in the market.
Imagine the fact that there is no standard and CE medical devices will not have a CE sign on them. There will be many products with the potential to provide poor service, where people need to pay and the results will be dissatisfied customers.
Also, keep in mind that standards such as CE certification force the company to make products that are safe and user-friendly. It forces the company to get CE certification because without it clients will not be sure of product quality.
And based on the need for testing CE, the entire company testing company was created to meet the needs of technology providers. So you see testing not done only for testing, or because someone feels like doing it. CE certification tests are carried out with clear goals to protect the average customer.
