★ Introduction to CE certification
CE is an abbreviation of the French, the English meaning "European Conformity namely the European Community , in fact, CE or European languages in many countries of the " EC " abbreviation for the phrase, the original phrase in English EUROPEAN COMMUNITY abbreviated as EC , due to the EC is in the French COMMUNATE EUROPEIA , Italian for the COMUNITA EUROPEA , Portuguese is COMUNIDADE EUROPEIA , Spanish COMUNIDADE EUROPE , etc., so change the EC for the CE . Of course, may also wish to CE deemed CONFORMITY the WITH EUROPEAN ( DEMAND ) (in line with European (request)), constitute the core of the European directive " main requirements " in the EC 1985 Nian 5In the “Resolution of New Method for Technical Coordination and Standards” ( 85 / C136 / 01 ) on July 7th , it has a specific meaning for the “ main requirements ” that are required for the purpose of formulating and implementing directives , that is, only for products that do not endanger humans and animals The basic safety requirements for the safety of goods and not the general quality requirements. The coordination directive only stipulates the main requirements, which are standard tasks.
★ CE certification model
For almost all EU product directives, the directive usually provides manufacturers with several CE certification (Conformity Assessment Procedures) modes (Module), manufacturers can tailor their own conditions, choose the most suitable for their own mode.
Generally speaking, the CE certification model can be divided into the following 9 basic models:
Module A: internal production control
Mode A: Internal production control (self-declaration)
Module Aa: intervention of a Notified Body
Mode Aa: Internal production control, plus 3rd party inspection
Module B: EC type-examination
Mode B: EC type test
Module C: conformity to type
Mode C: conform to type
Module D: production quality assurance
Mode D: Production quality assurance
Module E: product quality assurance
Mode E: Product quality assurance
Module F: product verification
Mode F: Product verification
Module G: unit verification
Mode G: Unit verification
Module H: full quality assurance
Mode H: Total quality assurance
Based on the different combinations of the above basic modes, several other different modes may be derived.
★ CE certification test content
During CE certification, the tested content is different according to different products; ordinary wired products are required to do LVD + EMC when doing CE; wireless products are required to do LVD + EMC + RF + Health when doing certification ,and many more.
With the continuous upgrading of products, there will be more problems with the safety performance of products, such as: high temperature, high pressure, high heat, fire, explosion, etc., countries around the world will increasingly test the safety hazards of products sold in their countries Strictly, it also requires related products to be tested for safety , and the corresponding countries will have different certifications.
EU: CE-LVD, GS, TUV-mark, KEMA, NEMKO, DEMKO, ENEC, BEAB, GOST, ErP
Asia: CCC, CQC, KC, PSE, S-mark, BSMI, PSB, SASO
North and South America: UL / cUL, FDA, ETL / cETL, CEC, cTUVus, Energy Star, CSA / CSAus, NOM, IRAM, UC
Australia and Africa: SAA, MEPS, SONCAP, SABS
Global certification mark: CB

★ Introduction of EMC
With the development of electrical and electronic technology, the electromagnetic environment is becoming more and more complex and deteriorating, and the electromagnetic compatibility EMC testing of electrical and electronic products is increasingly valued by governments and manufacturing companies of various countries. The legal requirements for electronic and electrical products in various countries are becoming stricter.
At present, in all major advanced countries in the world, in order to properly protect wireless communication and computer information control, electromagnetic interference (EMI) generated during the operation of commodities or should have appropriate electromagnetic anti-interference ability (EMS) are mandatory. Such as: FCC in the United States, VCCI in Japan, C-Tick in Australia, CE Mark in Europe, BSMI in Taiwan, CCC in China. Electronic information products that are about to enter the country must be applied and tested before they can be imported and legally sold.
