Understand the global mainstream certification marks of magnetic materials and downstream products-1
Certification is a form of credit guarantee. According to the definitions of the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC), it refers to the certification by a nationally recognized certification body that an organization’s products, services, and management systems comply with relevant standards, technical specifications (TS) or its mandatory requirements Conformity assessment activities. The benefits of certification are self-evident. It is a "Letter of Credit" for products, a "Physical Examination Certificate" for corporate management, and a "passport" for international trade.

There are various certifications around the world, and the certification requirements of different countries, different industries and different customers are not the same. For your reference, I have compiled the main international certification types of magnetic materials and related products of magnetic materials in terms of product safety and electromagnetic compatibility.
1. EU CE safety certification
CE certification is limited to the basic safety requirements for products that do not endanger the safety of humans, animals and goods, rather than general quality requirements. It is a safety conformity mark rather than a quality conformity mark.
The CE mark is a safety certification mark and is regarded as a passport for manufacturers to open and enter the European market. CE stands for CONFORMITE EUROPEENNE. All products affixed with the "CE" mark can be sold in the EU member states without meeting the requirements of each member state, thus realizing the free circulation of goods within the EU member states.
2. EU EMC electromagnetic compatibility certification
EMC is a directive in the CE certification. The full name of EMC is Electro Magnetic Compatibility, which is defined as "the ability of equipment and systems to work normally in their electromagnetic environment without causing unbearable electromagnetic disturbance to anything in the environment." This definition contains two meanings. First, the device should be able to work normally in a certain electromagnetic environment, that is, the device should have a certain degree of electromagnetic immunity (EMS); second, the electromagnetic disturbance generated by the device itself cannot be Other electronic products have excessive influence, namely electromagnetic disturbance (EMI).
The electromagnetic compatibility of electronic and electrical products is a very important quality index. It is not only related to the working reliability and safety of the product itself, but also may affect the normal operation of other equipment and systems, and is related to the electromagnetic environment. Protection issues. Since January 1, 1996, all electrical and electronic products must pass EMC certification before they can be sold on the EU market.
3. EU RoHS certification
RoHS is the abbreviation for the restriction of the use of certain hazardous substances in electrical and electronic equipment (the restriction of the use of certain hazardous substances in electrical and electronic equipment). The purpose of this standard is to eliminate lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls and polybrominated diphenyl ethers in electrical and electronic products. RoHS testing is aimed at all electrical and electronic products that may contain the above six hazardous substances in the production process and raw materials, mainly including: white household appliances (such as refrigerators, washing machines, microwave ovens, air conditioners, vacuum cleaners, water heaters, etc.), black household appliances (such as audio, Video products, DVDs, CDs, TV receivers, IT products, digital products, communication products, etc.), electric tools, electric electronic toys, medical electrical equipment.
According to the requirements of the EU WEEE & RoHS directives, domestic qualified third-party testing agencies separate products according to materials and use different materials to test for hazardous substances. Generally speaking:
Metal materials need to test four harmful metal elements such as (Cd cadmium/Pb lead/Hg mercury/Cr6+hexavalent chromium)
In addition to checking these four harmful heavy metal elements, the plastic material also needs to be tested for brominated flame retardants (polybrominated biphenyls PBB/polybrominated diphenyl ethers PBDE)
At the same time, packaging materials of different materials also need to be tested separately for heavy metals in packaging materials (94/62/EEC)
The EU’s CE certification is a standard law and regulation. It is a certification that products must do to enter the EU market, but the EU’s RoHS is not a compulsory certification. If the product is only CE certified, it can also achieve the purpose of sales, but it may have an impact on the product's own safety status in the market.
4. EU REACH certification
REACH is the abbreviation of EU regulation "REGULATION concerning the Registration, Evaluation, Authorization and Restriction of Chemicals". It is a chemical regulatory system established by the EU and implemented on June 1, 2007 .
This is a regulatory proposal concerning the safety of chemical production, trade, and use. The regulation aims to protect human health and environmental safety, maintain and improve the competitiveness of the EU chemical industry, and develop innovative capabilities for non-toxic and harmless compounds. The REACH Directive requires that all chemicals imported and produced in Europe must go through a comprehensive set of procedures such as registration, evaluation, authorization and restriction, in order to better and more simply identify the chemical components to achieve the purpose of ensuring environmental and human safety. The directive mainly includes several major items such as registration, evaluation, authorization, and restriction. In addition to the direct impact on chemical companies, REACH will have an impact on all companies that produce downstream chemical products, including textiles, machinery, toys, furniture, and more. There are more than 1 million products involved. Any product must have a registration file that lists the chemical ingredients, and explain how the manufacturer uses these chemical ingredients and the toxicity assessment report. All information will be entered into the European Chemical Agency for management.
5. American UL certification
UL (Underwriter Laboratories Inc.) Safety Laboratory is the most authoritative in the United States, and it is also the largest private organization engaged in safety testing and appraisal in the world. UL certification is a non-compulsory certification in the United States, mainly for product safety performance testing and certification, and its certification scope does not include the EMC electromagnetic compatibility characteristics of the product. UL certification mainly uses scientific testing methods to detect whether various materials, products, equipment, buildings, etc. are harmful to human life, property, environmental pollution, and product recyclability. UL certification can be compared with EU ROHS and Australia. Some large-scale internationally recognized qualifications such as SAA certification are equally famous.
6. U.S. FCC certification
FCC is the abbreviation of the Federal Communication Commission (Federal Communication Commission). FCC certification is a compulsory certification of EMC electromagnetic compatibility characteristics in the United States. Many radio application products, communication products and digital products require FCC approval to enter the US market.
FCC certification, also known as the United States Federal Communications Certification, includes computers, fax machines, electronic devices, radio receiving and transmission equipment, radio remote control toys, telephones, personal computers, and other products that may harm personal safety. If these products are to be exported to the United States, they must be tested and approved by a laboratory authorized by the government in accordance with FCC technical standards. Importers and customs agents have to declare that each radio frequency device complies with FCC standards, the FCC license.
7. Canadian CSA certification
CSA is the abbreviation of Canadian Standards Association. It was established in 1919 and is Canada's first non-profit organization dedicated to the development of industrial standards. At present, CSA is the largest safety certification body in Canada and one of the most famous safety certification bodies in the world. It can provide safety certification for all types of products in machinery, building materials, electrical appliances, computer equipment, office equipment, environmental protection, medical fire safety, sports and entertainment.
Products such as electronics and electrical appliances sold in the North American market need to obtain safety certification, and products that have obtained CSA certification can also enter the US market. (The CSA International logo with US or NRTL indicates that the product meets the applicable standards of the United States and can enter the US market)
