What is the difference between the ANSI and IEC?
International Electro technical Commission (IEC) was established in 1906, which is one of the world earliest non-governmental International electro technical standardization bodies, such as insulator, the United Nations and social council (ECOSOC) class a consulting organization. ISO was established in 1947, IEC department of electrical engineering incorporated into ISO, but still maintain its own technical, financial. According to ISO and IEC new agreement, the two organizations are legally independent organization; IEC is responsible for the relevant international standardization work in the field of electrical, electronic, by ISO in other areas.

American National Standards Institute (ANSI) is built by the companies, the government and the voluntary organization composed of other members. Their negotiation activities related to standards, review the national standards, and strive to improve the status of the United States in the international organization for standardization. In addition, the ANSI make about communication and network of international standard and American standard. High voltage insulator can follow ANSI standard.
ANSI is one of the members of IEC and ISO. ANSI is to those in specific areas to establish a standard group provides regional permission, such as the association of electrical and electronics engineers (IEEE).More and more the composite insulator buyers and manufacturers use ANSI standard.
