What are UL and CE certifications?
UL is the abbreviation of Underwriter Laboratories Inc UL Safety Laboratory is the most authoritative institution in the United States and a large private institution engaged in safety testing and evaluation in the world. UL certification is optional in the United States, mainly for the detection and certification of product safety performance, and its certification scope does not include EMC (electromagnetic compatibility) characteristics of products.

CE certification is limited to the basic safety requirements of products that do not endanger the safety of human beings, animals and goods, rather than the general quality requirements. The coordination instruction only specifies the main requirements, and the general instruction requirements are standard tasks. In the EU market, the "CE" mark is a compulsory certification mark. Whether products produced by enterprises within the EU or products produced by other countries want to circulate freely in the EU market, they must be labeled with "CE".

CE certification process

This process applies to all products covered by all ce.

1. Determine the directives and harmonization standards that the product meets.

Products covered by more than 20 directives need to be labeled with CE. These instructions cover different ranges of products, and the basic requirements of the products covered are listed in the instructions. EU Harmonized Standards are detailed technical documents used to guide products to meet the basic requirements of the Directive.

2. Determine the detailed requirements that the product should meet.

You must ensure that your products meet the basic requirements of relevant EU laws. Only when the product meets the requirements of all applicable harmonized standards can it be regarded as meeting the relevant basic requirements. Whether to apply the reconciliation standard is entirely voluntary, and you can also choose other ways to meet the corresponding basic requirements.

3, to determine whether the product needs to be announced to participate in the inspection.

Every instruction involved in your product has detailed provisions. Do you need a third-party announcement agency to participate in CE audit? Not all products need to be certified by the announcement agency, so it is very important to determine whether the announcement agency really needs to participate. These announcement agencies are authorized by the European Commission, and there is a detailed list in the documents of NANDO (new method directive announcement agency and designated agency).

4. Test the product and check its compliance.

It is the manufacturer's responsibility to test products and check whether they comply with EU regulations (conformity assessment process). Risk assessment is the basic rule in the assessment process. Only by meeting the requirements of relevant EU harmonization standards can the basic requirements of EU official regulations be met.

5. Draft and save the technical documents required by the manual.

The manufacturer must establish the technical document (TCF) of the product according to the requirements of the directive and the needs of risk assessment. If required by relevant authorized departments, the manufacturer shall submit technical documents and EC declaration of conformity for inspection.

6. Stick the CE mark on your product and make an EC conformity statement.
