Mechanical characteristics of conduction-cooled versions of Eurocard-based circuit card assemblies are described. This specification is applicable to, but not limited to, the VMEbus standard, an internal interconnect (backplane) bus intended for connecting processing elements to their immediate fundamental resources. The aim is to ensure mechanical interchangeability of conduction-cooled circuit card assemblies in a format suitable for military and rugged applications and to ensure their compatibility with commercial, double-height 16 mm, Eurocard chassis.

IEEE Standard for Mechanical Core Specifications for Microcomputers Using IEC 60603-2 Connectors
The basic dimensions of a range of modular subracks conforming to IEC 60297-3 (1984-01) and IEC 60297-4 (1995-03) for mounting in equipment according to IEC 60297-1 (1986-09) and ANSI/EIA 310-D-1992, together with the basic dimensions of a compatible range of plug-in units, printed boards, and backplanes, are covered. The dimensions and tolerances necessary to ensure mechanical function compatibility are provided. This standard offers total system integration guidelines with attendant advantages, such as reduction in design and development time, manufacturing cost savings, and distinct marketing advantages.
IEEE Standard for Additional Mechanical Specifications for Microcomputers Using the IEEE 1101.1-1998 Equipment Practice
A generic standard that may be applied in all fields of electronics where equipment and installations are required to conform to the 482.6 mm (19 in) equipment practice based on IEEE Std 1101.1-1991, IEC 297-3 (1984), and IEC 297-4 (1995). Dimensions are provided that will ensure mechanical interchangeability of subracks and plug-in units.
IEEE Standard for Mechanical Rear Plug-in Units Specifications for Microcomputers Using IEEE 1101.1 and IEEE 1101.10 Equipment Practice
Additional dimensions that will ensure mechanical interchangeability of subracks and plug-in units based on IEEE P1101.1 (D1.0, 1997), IEEE Std 1101.10-1996, and the environmental requirements of IEC 61587-1 (May 1998-Draft) and IEC 61587-3 (May 1998-Draft) are specified.
