UL is the U.S. Underwriters Laboratories (Underwriter Laboratories Inc.) abbreviation. UL Safety Testing Institute is the most authoritative in the United States, but also in the world engaged in safety testing and identification of the larger civil institutions. UL certification in the U.S. is a non-compulsory certification, mainly product safety testing and certification, the scope of certification does not include product EMC (electromagnetic compatibility) characteristics. UL certification is a non-mandatory certification in the United States, mainly product safety testing and certification, the scope of certification does not include product EMC (electromagnetic compatibility) characteristics.
CE certification, that is, limited to the product does not jeopardize the safety of humans, animals and goods in terms of basic safety requirements, rather than the general quality requirements, the harmonization of directives only provide for the main requirements of the general directive requirements is the task of the standard. In the EU market "CE" mark is a mandatory certification mark, whether it is within the EU enterprise production of products, or products produced in other countries, in order to be free to circulate in the EU market, must be affixed with the "CE" mark.

CE certification process
This process applies to all products covered by CE.
1. Determine the directives and harmonized standards that the product complies with
Products covered by more than 20 directives need to be affixed with the CE marking. These directives cover a different range of products, and the directive lists the basic requirements of the products covered. An EU harmonized standard is a detailed technical document used to guide a product to meet the basic requirements of a directive.
2. Determine the detailed requirements that your product should meet
You must ensure that your product meets the essential requirements of the relevant EU legislation. A product is considered to meet the relevant essential requirements if it meets the requirements of all harmonized standards to which it applies. The application of harmonized standards is entirely voluntary and you may choose to meet the respective essential requirements in other ways.
3. Determine whether your product requires the participation of a Notified Body
Each of the directives that your product is subject to has detailed provisions on whether a third party Notified Body is required to participate in the CE audit. Not all products are mandated to be certified by a Notified Body, so it is important to determine if you really need a Notified Body. These Notified Bodies are authorized by the European Commission and are listed in detail in the NANDO (New Approach Directive Notified Bodies and Designated Authorities) dossier.
4.Testing the product and checking compliance
It is the manufacturer's responsibility to test the product and check that it complies with the EU regulations (conformity assessment process). Risk assessment is the basic rule in the assessment process, and meeting the requirements of the EU harmonized standards will make it possible for you to satisfy the basic requirements of the official EU regulations.
5, draft and save the technical documents required by the directive
Manufacturers must establish the product's technical documentation (TCF) in accordance with the requirements of the directive to which the product conforms and the needs of risk assessment. If required by the relevant authorized department, the manufacturer needs to submit the TCF and EC Declaration of Conformity together for inspection.
6. Put CE marking on your products and make EC Declaration of Conformity.
