The standards developed within IEEE represent a consensus of the broad expertise on thesubject within the Institute as well as those activities outside of IEEE that have expressed an inter-est in participating in the development of the standard.Use of an IEEE Standard is wholly vol

The existence of an IEEE Standard does not implythat there are no other ways to produce, test, measure, purchase, market, or provide other goods andservices related to the scope of the IEEE Standard. Furthermore, the viewpoint expressed at thetime a standard is approved and issued is subject
8、 to change brought about through developments inthe state of the art and comments received from users of the standard. Every IEEE Standard is sub-jected to review at least every ve years for revision or reafrmation. When a document is morethan ve years old and has not been reafrmed, it is reasonable

11、When the need for interpretations is brought to the attention ofIEEE, the Institute will initiate action to prepare appropriate responses. Since IEEE Standards rep-resent a consensus of all concerned interests, it is important to ensure that any interpretation hasalso received the concurrence of a b

18、tinues to be the leading choice for theindustrial mechanical equipment practice, and is accepted throughout the world for all kinds of electronicsapplications. Among these are all major bus architectures, such as VME, CompactPCI, etc.This is why the Computer Societys Technical Committee on Microcomp
19、uters and Microprocessors found itappropriate to create an IEEE standard which further expands upon IEEE P1101.1 (D1.0, 1997) and the IEC60297-. series of standards, Dimensions of Mechanical Structures of the 482.6 mm (19 in) Series, IEC60297-3 (1984-01) and IEC 60297-4 (1995-03) for rear plug-in un
