What digital currency is UL
UL is short for Underwriter Laboratories Inc. UL safety testing institute is the most authoritative organization in the United States, and also the largest non-governmental organization engaged in safety testing and appraisal in the world. UL certification is a non compulsory certification in the United States, mainly for the testing and certification of proct safety performance, and its certification scope does not include the EMC (electromagnetic compatibility) characteristics of procts
CE certification refers to the basic safety requirements of procts that do not endanger the safety of human beings, animals and goods, rather than the general quality requirements. The coordination directive only specifies the main requirements, and the general directive requirements are the tasks of the standard. In the EU market, the "CE" mark is a compulsory certification mark. Whether it is procts proced by enterprises within the EU or procts proced in other countries, if they want to circulate freely in the EU market, they must affix the "CE" mark

CE certification process
this process is applicable to all procts covered by CE
1. Determine the directives and harmonized standards that the procts comply with. Procts covered by more than 20 directives need to be labeled with CE mark. These directives cover different ranges of procts and list the basic requirements of the procts covered. EU harmonized standards are the detailed technical documents used to guide procts to meet the basic requirements of the directive
You must ensure that your procts meet the basic requirements of relevant EU laws. Only when the proct meets the requirements of all applicable harmonized standards can it be regarded as meeting the relevant basic requirements. It is entirely voluntary to apply the harmonized standards. You can also choose other ways to meet the corresponding basic requirements3. Determine whether the proct needs to be inspected by the announcement body
every instruction involved in your proct has detailed provisions on whether the third-party announcement body needs to participate in the CE audit. Not all procts are required to pass the certification of the bulletin board, so it is very important to determine whether the participation of the bulletin board is really needed. They are all authorized by the European Commission and have a detailed list in the archives of Nando
4. Test procts and check their conformity
manufacturers have the responsibility to test procts and check whether they comply with EU regulations (conformity assessment process). Risk assessment is the basic rule in the assessment process. Only after meeting the requirements of relevant EU harmonized standards can you meet the basic requirements of EU official regulations
5. Draft and keep the technical documents required by the directive
the manufacturer must establish the proct technical documents (TCF) 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
6. Put CE mark on your procts and make EC declaration of conformity
