Please introduce the certification bodies IEEE and IEC, the International Electrotechnical Commission.

IEEE (Institute of Electrical and Electronics Engineers) and IEC (International Electrotechnical Commission) are two different organizations with distinct roles and objectives in the field of electrical and electronic engineering. Below is an introduction to each of these organizations. IEEE (Institute of Electrical and Electronics Engineers): IEEE is a professional organization dedicated to the education and technical innovation of professionals in the fields of electronic engineering, computer engineering, and related areas. Founded in 1963 through the merger of the American Institute of Electrical Engineers (AIEE) and the Institute of Radio Engineers (IRE), IEEE is the world's largest technical professional organization. Its activities include publishing journals, organizing conferences, and developing industry standards. The IEEE Standards Association (IEEE-SA) is a leading standards-setting body that develops global electronic and electrical standards. IEC (International Electrotechnical Commission): IEC is an international standardization organization established in 1906, specializing in the development of international standards in the field of electronic and electrical technologies. The standards developed by IEC cover a wide range of areas in electrical, electronic, and related technologies, including energy technology, electronic devices, batteries, solar energy, nanotechnology, and more. The goal of IEC is to promote international trade and technical cooperation, ensuring the safety, efficiency, and interoperability of products and systems. Although IEEE and IEC have different roles and objectives in the field of electrical and electronic engineering, they often collaborate to jointly promote the development and implementation of international standards. For example, sometimes IEEE standards are adopted as IEC international standards, and vice versa, to promote global technological consistency and compatibility.
