The EIA (electronics Industries Alliance in Arlington, Virgina, the USA) comes out from the RMA (radio Manufacturers Association, based 1924) as trading organisation and unites 1991 with the Telecommunications Industry Association (TIA).

The EIA releases standards, e.g. for interfaces such as RS-232 as standard for modem connections world-wide. Further well-known standards are RS-422, RS-423 and RS-485.

The EIA is also initiator and joint founder the Internet Security Alliance.

Members

The EIA knows memberships for second gate Members (combinations, which represent whole industrial sectors) apart from the membership for enterprises also. The second gate Members are

• the Telecommunications Industry Association (TIA),
• the electronics Components, Assemblies, equipment & Supplies Association (ECA),
• the Government Electronics and information Technology Association (GEIA) and
• the JEDEC solvently State Technology Association (JEDEC).

Enterprises can be either direct members of the EIA or but member second gate of a Members.

Development

1924 united the US-American radio manufacturers under the name Associated radio Manufacturers, around itself still in the same year in radio Manufacturers Association (RMA) umzubennen. The upswing of electronics brought new tasks, new members and appropriate name changes, 1950 in radio Television Manufacturers Association (RTMA), to 1953 in radio Electronics Television Manufacturers (RETMA) and 1957 in Electronics Industries Association (EIA). 1997 took place for the time being last renaming in Electronics Industries Alliance (EIA); this reflects the development away from the pure manufacturer combination.

An important subrange of the EIA, the information and Telecommunications Technologies Group (EIA/ITG), was fused 1988 with the United States Telecommunications Suppliers Association (USTSA) and separated into the again created Telecommunications Industry Association (TIA). 1991 were already subordinated the TIA however as second gate Member again the EIA.

Marking of standards

The EIA brought a multiplicity of important standards and standards out. The function and name change of the combination settled also in the designations of these standards and to provide there until today for confusion.

Originally the standards were identified with the prefix R-S and to a number, R-S meant radio second gate. With the extension on further fields of activity (except radios) the prefix remained, was however officially no more abbreviation. Today R-S is usually read as Recommended standard (Backronym).

In later years the EIA marked new standards and new versions of existing standards by the prefix EIA. With the establishment of the TIA for communication standards the prefix TIA was used, after the assumption of the TIA under the EIA finally EIA/TIA. The American National Standards Institute (ANSI), which has US-American place for standardization, the EIA and later the TIA receives accredited and the standards; therefore officially the prefix ANSI/EIA and/or ANSI/EIA/TIA.

In the consequence an individual standard, for instance the well-known standard 232 for the serial interface, alternatively RS-232, can be called EIA-232, TIA-232, EIA/TIA-232, ANSI/EIA-232, ANSI/EIA/TIA-232, etc. Formally correctly what stands on the standard, is natural: With the standard 232 the newest version ANSI/EIA/TIA-232-F-1997 is called, that from 1969 however RS-232-C (the suffix - F and/or - C marks the version standard, afterwards still the year follows) with newer versions.
