Members of the committees serve voluntarily and without compen

The standards developed within IEEE represent a consensus of the broad expertise on the subject within the Institute as well as those activities outside of IEEE which have expressed an interest in participating in the development of the stan

The existence of an IEEE Standard does not imply that there are no other ways to produce, test, measure, purchase, market, or provide other goods and services related to the scope of the IEEE Standard. Furthermore, the viewpoint expressed at the tim
9、e a standard is approved and issued is subject to change brought about through developments in the state of the art and comments received from users of the standard. Every IEEE Standard is subjected to review at least once every five years for revision or reaffirmation. When a document is more than
10、five years old, and has not been reaffirmed, it is reasonable to conclude that its contents, although still of some value, do not wholly reflect the present state of the art. Users are cautioned to check to determine that they have the latest edition of any IEEE Standard. Comments for revision of IE
11、EE Standards are welcome from any interested party, regardless of membership affiliation with IEEE. Suggestions for changes in documents should be in the form of a proposed change of text, together with appropriate supporting comments. Interpretations: Occasionally questions may arise regarding the
12、meaning of portions of standards as they relate to specific applications. When the need for interpretations is brought to the attention of IEEE, the Institute will initiate action to prepare appropriate responses. Since IEEE Standards represent a consensus of all concerned interests, it is important
13、 to ensure that any interpretation has also received the concurrence of a balance of interests. For this reason IEEE and the members of its technical committees are not able to provide an instant response to interpretation requests except in those cases where the matter has previously received forma
14、l consideration. Comments on standards and requests for interpretations should be addressed to: Secretary, IEEE Standards Board 445 Hoes Lane, P.O.

Such adoption does not assume any liability to any patent owner, nor does it assume any obligation whatever to parties adopting the standards documents. -,-,- iii Foreword (This foreword is not a part of IEEE Std 1101.2-
16、1992, IEEE Standard for Mechanical Core Specifications for Conduction-Cooled Eurocards.) This document describes mechanical characteristics for conduction-cooled versions of Eurocard-based circuit card assemblies. It is intended that this specification will be applicable to, but not limited to, the
17、VMEbus standard, an internal interconnect (backplane) bus intended for connecting processing elements to their immediate fundamental resources. This standard is intended to be a companion standard to other standards, which include IEEE Std 1101.1-1991, Mechanical Core Specifications for Microcompute
