Switching power supply safety certification
The power switch is the most common daily necessities, and its demand is also very large. Different certification marks are printed on the labels of switching power supplies or other products. It can be seen that certification has entered our life and has had a certain impact. . If the certification is obtained, it means that the product quality meets the national or international standards.
Common certification items for switching power supplies are:
1. China CCC, CQC, China Energy Efficiency Label. 3C certification is the most common electronic product certification in China, and its English name is China Compulsory Certification, namely "China Compulsory Product Certification". 3C certification is a product conformity assessment system implemented by the Chinese government in accordance with laws and regulations in order to protect consumers' personal safety and national security, strengthen product quality management. 3C certification is the most basic safety certification, not a product quality mark. Consumers can go to the China Quality Certification Center to inquire about the power supply manufacturer through the 3C certification number of the power supply.
2. EU CE, ROHS, EuP directives. CE comes from the French "CommunateEuroppene", which means the European Union. CE is also a safety certification mark. We can regard it as the European "3C" standard. Products affixed with the CE mark can be sold within the EU member states without having to meet the requirements of each member state. In order to realize the free circulation of goods, China's domestic power supplies have generally passed this certification. RoHS is a mandatory standard established by EU legislation, and its full name is "Restriction of Hazardous Substances in Electrical and Electronic Equipment". The standard was officially implemented on July 1, 2006, and is mainly used to standardize the materials and process standards of electrical and electronic products, making it more conducive to human health and environmental protection. The purpose of this standard is to eliminate 6 substances including lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls and polybrominated diphenyl ethers in electrical and electronic products, and it mainly stipulates that the content of lead should not exceed 0.1%. ROHS is an important symbol of energy conservation and environmental protection. When purchasing a power supply, you must pay attention to whether the power supply has passed this certification, so as to benefit your own health and reduce environmental pollution when it is discarded in the future.
3. American UL, ETL, FCC, CEC and Energy Star. The full name of UL is Underwriter Laboratories Inc. (Underwriters Laboratories) is the most authoritative, non-profit private safety testing organization in the United States. It mainly conducts safety tests and inspections on various equipment, systems and materials to confirm whether there is any danger to life and property, and publishes the inspection results. UL has published hundreds of standards, most of which are adopted by ANSI (American National Standards Institute), and now UL certification has become one of the most stringent certifications in the world. In general, UL standards can be divided into: requirements for product structure, requirements for raw materials used in products, requirements for components used in products, requirements for testing instruments and test methods, requirements for product marks and instructions, etc. . UL certification has many marks depending on the scope of application and the area of application. You can use the power supply with this type of certification with confidence.
4. Canadian CSA, CUL, IC.
5. Australia SAA, C-tick, MEPS.
6. Korea KC, Mic-mark, Korean energy efficiency label.
7. German GS, international CB.
8. Kuwait KUCAS, Nigeria SONCAP, Saudi Arabia SASO.
9. Japan PSE, Philippines ICC, Kenya PVOC, Iran VOC.
In terms of chemical environmental protection testing, in addition to the common RoHS, we can also carry out REACH, PAHs polycyclic aromatic hydrocarbons, POHS, CPSIA, California 65, LMBG, Phthalates, TBBP-A tetrabromobisphenol A, MSDS, azo AZO, Battery Directive, Packaging Directive, Halogen, PCB Polychlorinated Biphenyls, PVC Polyvinyl Chloride, etc.
