Standards & Architecture
The Eurocard mechanical architecture was defined originally under IEC-60297-3. Today, the most widely recognized standards for this mechanical structure are IEEE 1101.1, IEEE 1101.10 (also known commonly as "dot ten") and IEEE 1101.11. IEEE 1101.10 covers the additional mechanical and EMI features required for VITA 1.1-1997(R2002) which is the VME64 Extensions standard as well as PICMG 2.0 (R3.0) which is the CompactPCI specification.
The IEEE 1101.11 standard covers rear plug-in units that are also called rear transition modules or RTMs.
The Eurocard is a mechanical system and does not define the specific connector to be used or the signals that are assigned to connector contacts.
The connector systems that are commonly used with Eurocard architectures include the original DIN 41612 connector that is also standardized as IEC 60603.2. This is the connector that is used for the VMEbus standard which was IEEE 1014. The connector known as the 5-row DIN which is used for the VME64 Extensions standard is IEC 61076-4-113. The VME64 Extension architecture defined by VITA 1.1-1997 (R2002).
Another popular computer architecture that utilizes the 6U-160 Eurocard is CompactPCI and CompactPCI Express. These are defined by PICMG 2.0R3 and PICMG Exp0 R1 respectively. Other computer architectures that utilize the Eurocard system are VXI, PXI, and PXI Express.
A computer architecture that used the 6U-220 Eurocard format was Multibus-II which was IEEE 1296.
Because the Eurocard system provided for so many modular card sizes and because connector manufacturers have continued to create new connectors which are compatible with this system, it is a popular mechanical standard which is also used for innumerable "one-off" applications.
Conduction-cooled Eurocards are used in military and aerospace applications. They are defined by the IEEE 1101.2-1992(2001) standard.
The Eurocard standard is also the basis of the "Eurorack" format for modular electronic music synthesizers, popularized by Doepfer and other manufacturers.

Famous quotes containing the words standards and/or architecture:
“The standards of His Majesty’s taste made all those ladies who aspired to his favour, and who were near the Statutable size, strain and swell themselves, like the frogs in the fable, to rival and bulk and dignity of the ox. Some succeeded, and others burst.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
“They can do without architecture who have no olives nor wines in the cellar.”
—Henry David Thoreau (1817–1862)
