IEEE 1101.2-1992

1101.2-1992 is a technical standard for cooled Eurocards used in computing and electronic processing equipment. It addresses the mechanical and environmental considerations needed for card-based assemblies that rely on controlled cooling, helping designers and buyers align on fit, airflow, and operational reliability. As an inactive standard, it remains relevant for legacy systems and documentation where Cooled Eurocards must still be identified, assessed, or sourced with the correct engineering reference.

About 1101.2-1992

This standard defines requirements associated with cooled Eurocard assemblies in the context of components, circuits, devices, and systems. It is aimed at card-level hardware that depends on enclosure design and thermal management to maintain performance within expected limits. In practice, 1101.2-1992 helps establish a common basis for dimensions, installation compatibility, and cooling-related expectations, which is useful when comparing hardware, reviewing technical files, or supporting older system architectures.

Where is 1101.2-1992 used?

1101.2-1992 is most relevant in modular computing equipment, electronic racks, and other systems built around Eurocard-style boards. It may be used in control cabinets, instrumentation platforms, industrial electronics, and legacy processing systems where card insertion, spacing, and cooling behavior must be coordinated. Engineers, integrators, and maintenance teams typically use the standard when working with compatible enclosures, replacement boards, or documentation for established hardware platforms.

Importance in practice

In practice, this standard helps reduce mismatch between boards, housings, and cooling arrangements. That matters for procurement, maintenance, and design control, especially when a cooled card must fit into an existing system without creating thermal or mechanical issues. Using 1101.2-1992 as a reference can support consistency across suppliers, improve testing and acceptance decisions, and lower the risk of unreliable operation in equipment where heat removal is part of the design assumption.
