The International Electrotechnical Commission (IEC) is one of the most influential and authoritative international standardization and conformity assessment organizations globally. It is responsible for formulating and publishing international standards and conformity assessment rules in the field of electrotechnics and electronics, as well as establishing and operating an international certification and mutual recognition system.

China is a permanent member of the International Electrotechnical Commission (IEC), a member of all four international certification and mutual recognition systems of the IEC, and an active participant in the IEC's 203 technical committees and subcommittees. The good cooperation between China and the IEC plays an increasingly significant role in promoting international electrotechnical standardization and conformity assessment, facilitating the development of China's manufacturing industry and foreign trade, and protecting the rights and interests of consumers and relevant parties from various countries.

IEC certification is an abbreviation of the International Electrotechnical Commission, a non-governmental international organization and a Class A advisory body to the United Nations Economic and Social Council. It was officially established in November 1906 and is the world's oldest specialized international standardization body. Its headquarters are located in Geneva. After the establishment of ISO in 1947, IEC was incorporated into ISO as the electrical department, but it maintained its technical and financial independence. According to the new agreement between ISO and IEC in 1976, both organizations are legally independent. IEC is responsible for international standardization work related to electrical and electronic fields, while ISO is responsible for other fields. The purpose of IEC is to promote international cooperation in standardization and related issues in the electrical and electronic fields, and to enhance mutual understanding. To achieve this goal, various publications, including international standards, are published, and it is hoped that national committees will use these international standards where their national conditions permit. The work areas of IEC include electrical technology in the fields of electricity, electronics, telecommunications, and atomic energy. More than 3,000 international electrical standards have been developed.
