7、Standards Coordinat-ing Committees of the IEEE Standards Association (IEEE-SA) Standards Board. Members of thecommittees serve voluntarily and without compensation. They are not necessarily members of theInstitute. The standards developed within IEEE represent a consensus of the broad expertise on t
8、hesubject 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 voluntary. The existence of an IEEE Standard does not implythat there are no other ways to produce, test,
9、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 to change brought about through developments inthe state of the art and comments received from users o
10、f 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 to conclude that its contents,although still of some value, do not wholly reect the present state of t
11、he art. Users are cautioned tocheck to determine that they have the latest edition of any IEEE Standard.Comments for revision of IEEE Standards are welcome from any interested party, regardless ofmembership afliation with IEEE. Suggestions for changes in documents should be in the form of aproposed
12、change of text, together with appropriate supporting comments.Interpretations: Occasionally questions may arise regarding the meaning of portions of standards asthey relate to specic applications. When the need for interpretations is brought to the attention ofIEEE, the Institute will initiate actio
13、n 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 balance of interests. For this reason, IEEE and the members of itssocieties and Standards Coordinating C

19、E Standard for Mechanical Rear Plug-in Units Specica-tions for Microcomputers Using IEEE 1101.1 and IEEE 1101.10 Equipment Practice.)Despite the push for metrication, the Euroboard (19 in based) continues to be the leading choice for theindustrial mechanical equipment practice, and is accepted throu
20、ghout 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 Microcomputers and Microprocessors found itappropriate to create an IEEE standard which further expands upon IE
21、EE 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 units.This standard is an extension of IEEE P1101.1 (D1.0, 1997) and IEEE Std 1101.10-1996 (submitted to
22、 theIEC) and denes the mechanical rear plug-in unit sizes and interface details.
