The meanings of common signs are as follows:
1. The CE mark is the European Common Market safety mark. It is a mark that declares that a product complies with relevant EU directives. The use of the CE mark is a mandatory requirement for EU members to sell products. At present, the EU has promulgated 12 categories of product directives, mainly including toys, low-voltage electrical appliances, medical equipment, telecommunications terminals (telephone types), automatic weighing instruments, electromagnetic compatibility, machinery, etc.
2. UL is the Underwriters Laboratories of the United States. It is an internationally recognized authority for safety inspection and UL marking. It issues safety assurance marks for mechanical and electrical products, including civilian electrical products. Some UL safety standards have been adopted by the U.S. government as national standards. For products to be sold in the US market, the UL certification mark is an indispensable condition. UL is the abbreviation of Underwriter Laboratories Inc. UL Safety Testing Institute is the most authoritative in the United States and the largest private institution engaged in safety testing and identification in the world. It is an independent, non-profit, professional organization that conducts experiments for public safety. It uses scientific testing methods to study and determine whether various materials, devices, products, equipment, buildings, etc. are harmful to life and property and the degree of harm; it determines, writes, and issues corresponding standards and helps reduce and prevent hazards to life. We will collect information on property damage and conduct fact-finding research at the same time.
3. The GS mark is a German safety certification mark. It is a European certification mark authorized by the German Ministry of Labor and implemented by a special TUV legal entity for product sales around the world. Although the GS mark is not a legal requirement, it does make the manufacturer subject to strict German (European) product safety laws when a product malfunctions and causes an accident. Therefore, the GS mark is a powerful market tool that can enhance Customers' confidence and desire to buy, usually GS certified products have higher unit sales prices and are more popular. The GS mark is a safety certification mark issued by TUV, VDE and other agencies authorized by the German Ministry of Labor. The GS mark is a safety mark accepted by customers in Europe. Generally, GS certified products sell at higher unit prices and are more popular.
4. The CB system is a global mutual recognition system established by the International Electrotechnical Commission (IECEE). 45 certification bodies from 34 countries around the world participate in this mutual recognition system. The member states and member institutions of this organization are constantly expanding. . After an enterprise obtains a CB certificate from one of the certification agencies, it can more easily convert it into a certification certificate from another agency, thereby obtaining an access permit to enter the relevant national market. The member countries of the CB system include all important export regions of China's mechanical and electrical products: the United States, Japan, Western Europe, Northern Europe, Poland, Russia, ASEAN, South Africa, Australia and New Zealand, etc.
5. The International Electrotechnical Commission (IEC for short) is the earliest non-governmental international electrotechnical standardization organization in the world and a Class A advisory organization of the United Nations Economic and Social Council (ECOSOC). After the establishment of ISO in 1947, IEC was merged into ISO as the electrical department, but it still maintained its independence technically and financially. According to the new agreement between ISO and IEC in 1976, both organizations are legally independent organizations. IEC is responsible for international standardization work in the electrical and electronic fields, while ISO is responsible for other fields. IEC member countries include the vast majority of industrially developed countries and some developing countries. These countries account for 97% of the world's population, produce and consume 95% of the world's electricity, and manufacture and use electrical and electronic products that account for 90% of the world's output. The purpose of IEC is to promote the international unification of electrical standards, international cooperation in standardization and related aspects in the field of electrical and electronic engineering, and to enhance mutual understanding among nations. To achieve this purpose, it publishes various publications including international standards. It is also hoped that national committees will use these international standards when their own national conditions permit. The IEC's work areas include electrotechnical technology in electricity, electronics, telecommunications and atomic energy.
