常见国际电气标准组织

American National Standards Institute. An industry body that publishes standards, such as standards developed by the IEEE.

This is the European acronym for the European Committee for Electrotechnical Standardization. The European technical

organization responsible for coordination of standards for safety and electromagnetic emissions for electrical equipment in the European Economic Community (EEC). The EEC(欧共体) is working toward having a uniform set of standards that will apply for all EEC countries.

CEN成员是以下国家的国家标准实体:澳大利亚,比利时,丹麦,芬兰,法国,德国,希腊,冰岛,爱尔兰,意大利,卢森堡,荷兰,挪威,葡萄牙,西班牙,瑞士,瑞典,英国.

Canadian Standards Organization. This is a Canadian government organization that evaluates the safety of electrical equipment. It is not legal to sell electrical equipment in Canada without CSA approval (although such sales occur frequently). The standards and test procedures of the CSA are similar to but not identical to those of the UL in the USA. Equipment is not CSA approved unless it bears the circular CSA mark.

This is European Community standard specifying the limits of radio frequency emissions which appliances and other electrical equipment are allowed. The standard indicates the maximum allowable emissions either radiated or conducted via the power cord at various frequencies. Some countries still use the older VDE0871 emission standards, which are nearly identical. In the USA, the FCC has a similar standard.

A European test standard for UPS system safety. Supercedes and is a superset of the IEC950 standard formerly used for UPS

testing. In addition to the typical safety tests found in the IEC950 standard, this standard includes special sections on batteries and other safety concerns specific to UPS systems. UPS products are normally certified to this standard by VDE, TUV, SEMKO or other authorized certification body. Many vendors whose products do not meet this standard nevertheless claim compliance with the standard. Therefore it is very important to make sure that an authorized certification body has certified the product.

The U.S. Federal communications Commission specifies the maximum amounts of conducted noise signals (EMI) and radio frequency interference (RFI) that computer equipment is permitted to generate in Part 15 of the FCC Rules and Regulations. These limits are set in order to prevent computer equipment from interfering with the operation of radio and television receivers. Two different limits have been set, depending on the typical application and marketing of the computer equipment. The class "A" FCC limits are for equipment intended for use in commercial and industrial environments. The more

The International Electrotechnical Commission. An international organization that writes standards for safety for electrical and other equipment. Many IEC standards were adopted from the German VDE, which was the main historical standards-writing body in Europe. One goal of the IEC is to harmonize differing standards between European countries to facilitate free trade. The U.S. Underwriters Laboratories (UL) and the Canadian CSA are members of the IEC and it is likely that UL and CSA standards will also converge with the IEC standards in the future.

Institute of Electrical and Electronic Engineers. A professional society and standards writing body for the U.S. Electronics industry.

An international power connector standard developed by the international Electrotechnical Commission (IEC) used mainly with input power cordsets. It is possible when using cordsets which incorporate this connector to connect power to a product with any of nine different cordsets so that the product can be easily modified to operate anywhere in the world.

An international standard for safety or data processing and related equipment. IEC950 specifies rules regarding construction, insulation, and safety features of computer equipment. Ordinarily, a product tested by TUV or VDE is checked for compliance with IEC950.
