IEC 60917-2:1992

IEC 60917-2:1992 defines the sectional specification for interface co-ordination dimensions in the 25 mm equipment practice, supporting mechanical structure development for electronic equipment. It is relevant where designers, manufacturers, and procurement teams need a common dimensional basis for chassis, subassemblies, and related enclosures. By aligning mechanical interfaces early in the engineering process, the document can help reduce fitting issues, simplify documented evaluation, and support more consistent technical review across product lines and suppliers.

IEC 60917-2:1992 standard overview

IEC 60917-2:1992 focuses on interface co-ordination dimensions within the 25 mm equipment practice, making it a practical reference for modular mechanical design. As Part 2 of the modular order for the development of mechanical structures for electronic equipment practices, it is mainly concerned with dimensional compatibility rather than detailed product performance. That makes it useful in engineering documentation, conformity assessment preparation, and technical validation where consistent mechanical interfaces are needed for operational consistency and controlled assembly.

Applications of IEC 60917-2:1992

This reference is typically used in the planning and review of electronic equipment frames, rack-based assemblies, plug-in units, and related modular structures where the 25 mm grid or spacing concept is applied. It may also support procurement specifications, laboratory evaluation of mechanical fit, and verification activities for equipment intended to integrate with established enclosure systems. In practice, teams use it to improve interoperability between components and to maintain alignment between design intent, manufacturing constraints, and compliance workflows.

Why IEC 60917-2:1992 matters

IEC 60917-2:1992 matters because dimensional coordination is often a prerequisite for safe and reliable integration of electronic equipment. Clear interface rules can reduce mechanical mismatch, limit rework during assembly, and improve testing consistency across variants or suppliers. For organizations handling technical assessment, the document can support procurement review, quality workflows, and conformity assessment preparation by giving all parties a shared basis for mechanical compatibility. It is especially valuable where risk management depends on predictable fit, repeatable installation, and disciplined engineering validation.

• Supports mechanical interface coordination for modular electronic equipment structures
