EveryIEEE Standard is subjected to review at least every five years for revision or reaffirmation. When a document is morethan five years old and has not

18、ased on the Eurocard formfactor, the IEEE Computer Society Technical Committee on Microcomputers and Microprocessors found itappropriate to form an IEEE standard to expand 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
19、 (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 compatibility (EMC), and electrostatic discharge (ESD) function compatibility. Thisadditional standard will be in conformance wi
20、th 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 design and development time, manufacturing cost savings, and distinct marketing advantages.This standard covers additional standardize
21、d 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 board anbackplane related dimensions for the IEC 603-2 Type C, 3-row and expanded 5-row connector series and a plug-inunit/subrack
