What is the certification of the power adapter?
The product certification system originated in the United Kingdom at the beginning of the 20th century. With the changes of the times, it has become an effective method for product safety, quality, environmental protection and other characteristics evaluation, supervision and management.
The International Organization for Standardization (ISO) defines product power adapter certification as a 3rd party through the inspection and evaluation of the power supply company's quality management system and sample type tests to confirm whether the company's products, processes or services meet specific requirements, and whether it has continuous and stable production that meets the standard requirements The ability of the product and the procedure for giving written proof.

It can be seen that certification can be divided into:
1. Enterprise management system certification (such as ISO9001, ISO14001)
2. Product type certification: The basis of type inspection is the product standard. The number of samples required for the inspection is determined by the certification body, and the sampling location is randomly selected from the final product of the power adapter manufacturer., such as common CE, UL, CB, TUV, etc.
Significance of product certification:
If a company's product has passed the product certification of an authoritative certification body, it can obtain a "certification certificate" issued by the certification body and allow the certification mark to be printed on the certified product. This type of certification, through trust endorsement, can enable companies to establish a good reputation and brand image through product certification. At the same time, it also allows customers and consumers to identify the quality and safety of products through certification marks.
Governments all over the world have established such certification systems through legislation and set up their own product certification agencies, using different certification marks, such as UL in the United States, CE in the European Union, CCC in China, PSE in Japan, KC in South Korea, etc. In order to ensure product quality and safety, and safeguard consumer rights, it has also become a new international trade barrier.
Common certification items:
At present, in the field of power supply, the most common product certification items are divided into two categories, namely EMC and safety regulations. There are also energy efficiency, RoHs, WEEE, etc.
