IEC 60917-2-4:2010

IEC 60917-2-4:2010 defines interface co-ordination dimensions for the 25 mm equipment practice, with specific adaptation dimensions for subracks or chassis used in cabinets or racks in accordance with IEC 60297-3-100 (19 in). As a technical reference, it helps engineers and procurement teams align mechanical structure choices with established dimensional interfaces, supporting compatibility during design review, documented evaluation, and conformity assessment. For organizations working with modular electronic equipment architectures, IEC 60917-2-4:2010 is relevant where consistent fit, interchangeability, and controlled integration are part of the workflow.

What is IEC 60917-2-4:2010?

This document forms part of the modular order for developing mechanical structures for electronic equipment practices, focusing on sectional specification details for interface-coordination dimensions. Its purpose is to help define how subracks or chassis adapt within cabinets or racks built to the 19 in arrangement described in IEC 60297-3-100. In practice, it serves as a design and compliance reference for dimensional alignment, supporting technical review, engineering documentation, and verification activities where mechanical compatibility must be assessed consistently.

Applications of IEC 60917-2-4:2010

The guidance is most relevant in electronic equipment packaging, modular enclosure design, rack integration, and related product evaluation workflows. It may be used by engineering teams developing subracks or chassis intended for cabinet-mounted or rack-mounted assemblies, especially where operational consistency and interface matching are important. It is also useful in procurement specifications, laboratory evaluation, and configuration control when organizations need a documented basis for comparing mechanical form factors and checking dimensional suitability before build or deployment.

Why is IEC 60917-2-4:2010 important?

Using IEC 60917-2-4:2010 can reduce integration risk by giving teams a common dimensional reference for mechanical interfaces in electronic equipment systems. That matters for interoperability, procurement accuracy, and technical validation, particularly when multiple suppliers or rack-based assemblies are involved. It also supports quality workflows by improving consistency across design, testing, and acceptance review, which can simplify compliance preparation and lower the chance of fit issues during installation or system assembly.
