The International Electrotechnical Commission (IEC) is "the leading global organization that prepares and publishes international standards for all electrical, electronic and related technologies." Electrotechnologies include electronics, magnetics and electromagnetics, electroacoustics, multimedia, telecommunication, and energy production and distribution. The standards are developed so that "a component or system manufactured to IEC standards and manufactured in country A can be sold and used in countries B through to Z." The website provides a brief introduction to the IEC conformity assessment schemes (used to assure customers of product quality) and highlights other resources. For example, a selection from the International Electrotechnical Vocabulary (IEV), which is available for purchase in print as a series or as a CD-ROM, is posted here. Access to the database on Graphical Symbols for Use on Equipment as well as the database containing graphical symbols for use in electrotechnical diagrams requires a paid subscription. Many features of the website seem to be posted specifically for members of IEC Technical Committees and Subcommittees members of IEC Technical Committees and Subcommittees, however, visitors may view a list of IEC patent declarations or browse the posted requests for approval, meeting documents, and IEC reports. Also of interest are the Zones, which address issues such as approaches to color management, electromagnetic compatibility, achieving functional safety, and alternative energies. An overview of the International System of Units, or SI, is also available.
