What is TUV certification? What are the benefits of TUV certification?
TUV mark is a safety certification mark customized by Germany’s TUV for component products, which is widely accepted in Germany and Europe. At the same time, when applying for the TUV mark, enterprises can apply for a CB certificate together, thereby obtaining certificates from other countries through conversion. Moreover, after the product passes the TUV certification , Germany’s TUV will recommend these products to rectifier manufacturers who come to inquire about qualified component suppliers; in the process of whole machine certification, all components with the TUV mark are exempt from inspection.

TUV certification purpose
The purpose of applying safety standards is to prevent personal injury and property loss caused by various dangers that may occur during the use of home appliances, mechanical products, and automotive products.
Including electric shock or electric shock, overheating or fire, mechanical dangers, radioactive hazards, and chemical hazards.
TUV certification standards
Home appliance regulations around the world are based on the IEC standard IEC60335.
Among them, the European standard is the closest to the international standard.
The European standard is divided into two parts: the first part EN60335-1 is the comprehensive requirements for home appliances; the second part EN60335-2 is the special requirements for various types of home appliances, and this part has dozens of standards.
TUV certified safety
The European electrical safety standard is EN60950, which is also the technical specification for the German TUV information product GS certification. For computer monitors, GS certification
It also includes EN50279 standard and ISO9241 series standard. Since the information product safety standards of all countries in the world are based on the IEC950 standard of the International Electrotechnical Commission, when companies apply for GS certification from TUV of Germany , they should pay attention to applying for safety certification from other countries at the same time.
