the "ce" mark is a safety certification mark, which is regarded as the passport opened by the manufacturer and entered the European market. CE stands for Conformite Europe. All products labeled with "CE" can be sold in EU member states without meeting the requirements of each member state, thus realizing the free circulation of goods in EU member states.

CE certification-issuing agency (1) Declaration of Conformity/Declaration of Compliance issued by enterprises independently. This certificate is a self-declaration and should not be issued by a third-party agency (intermediary or testing and certification agency). Therefore, it can be replaced by the enterprise Declaration of Conformity in EU format.

(2) certificate of compliance/certificate of compliance, which is a compliance statement issued by a third-party agency (intermediary or testing certification agency). It must be accompanied by technical data such as test report TCF, and at the same time, the enterprise must sign a Declaration of Compliance.

(3) EC attitude of conformity, which is a certificate issued by the Notified Body of the European Union. According to EU regulations, only NB is qualified to issue the CE declaration of EC Type.

CE Certification-Process This process applies to all products covered by CE:

Step 1: Determine the directives and harmonization standards that the products meet

Products covered by more than 2 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 directives.

Step 2: Determine the detailed requirements that the product should meet

You must ensure that your product meets 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 harmonization standard is completely voluntary, and you can also choose other ways to meet the corresponding basic requirements.

Step 3: Determine whether the product needs the participation of the announcement organization

Every instruction involved in your product has detailed provisions on whether the third-party announcement organization needs to participate in the CE audit. Not all products are required 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 have a detailed list in the file of NANDO (new method directive announcement agency and designated agency).

Step 4: Test the product and check its compliance

It is the manufacturer's responsibility to test the product and check whether it meets the EU regulations (conformity assessment process). Risk assessment is the basic rule in the assessment process. Only after meeting the requirements of relevant EU harmonization standards can you meet the basic requirements of EU official regulations.

Step 5: Draft and save the technical documents required by the directive

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

step 6: affix the CE mark to your product and make an EC declaration of conformity

the ce mark must be affixed to the product by the manufacturer or its authorized representative. CE mark must be clearly and permanently affixed to the product or its nameplate according to its standard pattern. If the announcement organization participates in the product certification, the CE mark must bear the announcement number of the announcement organization. The manufacturer is obliged to draft the EC declaration of conformity and sign it to prove that the product meets the CE requirements.

after the above six steps, your products with CE logo can circulate smoothly in the European market.

UL certification

UL is short for Underwriter Laboratories Inc UL Safety Laboratory is the most authoritative institution in the United States, and it is also a large private institution engaged in safety testing and appraisal in the world.

5. The applicant is authorized to use the UL mark

The UL regional inspector in China contacts the production factory for the first factory inspection (initial production inspection. IPI). The inspector checks the storage of your products and their parts in the production line and warehouse to confirm whether the product structure and parts are consistent with the detailed rules for tracking service. If required in the detailed rules, the regional inspector will also conduct witness experiments. When the inspection results meet the requirements, the applicant is authorized to use the UL mark.

after IPI, inspectors will go to the factory irregularly to inspect the product structure and witness experiments. The frequency of inspection is determined by the product type and production. Most types of products are inspected at least four times a year. The inspector's inspection is to ensure that the products continue to meet UL requirements. Please inform UL before you plan to change the product structure or components. For minor changes, there is no need to repeat any experiments. UL can quickly modify the tracking service details so that inspectors can accept such changes. When UL thinks that the change of the product affects its safety performance, it needs to apply for the company to re-submit the sample for necessary testing.

the cost of tracking service is not included in the test fee.

if the product test resULts can't meet the requirements of UL standard, UL will inform the applicant to explain the existing problems. after the applicant improves the product design, he can re-submit the product. you shoULd tell the ul engineer what improvements have been made to the product so that he can decide that the above steps are the steps to apply for ul certification.
