The existence of an IEEE Standard does not implythat there are no other ways to produce, test,

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

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

When the need for interpretations is brought to the attention ofIEEE, the Institute will initiate actio

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.
