17、 the IEEE Std 1101.1-1991 Equipment Practice.)With the widespread acceptance of international (IEC) microcomputer architectures based on the Eurocard formfactor, the IEEE Computer Society Technical Committee on Microcomputers and Microprocessors found itappropriate to form an IEEE standard to expand

18、 upon IEEE Std 1101.1-1991 and the IEC 297 series of standards,Dimensions of Mechanical Structures of the 482.6 mm (19 in) Series (IEC 297-1, IEC 297-3 and IEC 297-4). This additional standard provides design engineers with the dimensions and tolerances necessary to ensuremechanical, electromagnetic

19、 compatibility (EMC), and electrostatic discharge (ESD) function compatibility. Thisadditional standard will be in conformance with IEC Drafts 48D/1587-1 and 48D/1587-3.This additional standard offers mechanical, EMC, and ESD system integration details. It offers advantages such asreduction in desig

20、n and development time, manufacturing cost savings, and distinct marketing advantages.This standard covers additional standardized dimensions of a range of EMC subracks and associated EMC plug-inunits, injector, extractor and keying device handles for plug-in units and associated subracks, printed b

21、oard anbackplane related dimensions for the IEC 603-2 Type C, 3-row and expanded 5-row connector series and a plug-inunit/subrack ESD protection concept.At the time this standard was completed, the IEEE Std 1101.10-1996 Working Group had the following membership:Eike Waltz, Chair Frank Hom, Secretar
