Overview
EN IEC 62966-1:2019 - Mechanical structures for electrical and electronic equipment - Aisle containment for IT cabinets - Part 1: Dimensions and mechanical requirements defines the dimensional and mechanical criteria for aisle containment systems used with IT cabinets (those covered by the IEC 60297 and IEC 60917 series). The standard aims to ensure consistent, cost‑effective installation and energy‑efficient operation of containment systems in data centres and server rooms, improving airflow separation and equipment reliability.
Key topics and requirements
- Scope and intent: Applies to aisle containment that separates hot and cold aisles for rows of IT cabinets; intended to support energy‑efficient cooling of IT equipment.
- Design arrangements: Preferred and optional layout configurations for aisle containment, including arrangements for mixed cabinet sizes and integration with building structural elements or walls.
- Dimensions: Specifies required aisle widths and cabinet dimensional interfaces (height, width, plinth considerations) to guarantee compatibility with IEC 60297 / IEC 60917 cabinet families (tables in the standard list standardised dimensions).
- Top cover and ceiling design: Requirements for top cover elevation and the design of the containment ceiling to support airflow control, access and mechanical loads.
- Airflow orientation & ducts: Guidance for adapting airflow direction, and requirements for secure air duct connections and penetrations to avoid recirculation and leakage.
- Mechanical performance: Criteria for air tightness, structural stability and load‑bearing capability of containment components to ensure safety and durable operation.
- Testing & normative references: References to related tests and standards (e.g., IEC 61587 series) for environmental, seismic and mechanical verification.
Applications and users
EN IEC 62966-1:2019 is directly applicable to:
- Data centre designers and consultants specifying aisle containment for hot‑aisle/cold‑aisle layouts
- IT cabinet and containment manufacturers ensuring product compliance and interoperability with IEC 60297 / IEC 60917 cabinets
- HVAC and cooling engineers optimizing airflow separation and energy efficiency
- Facility managers and installers planning safe, maintainable containment installations
- Certification bodies and integrators verifying mechanical and dimensional conformity
Practical benefits include reduced cooling energy consumption, predictable airflow management, easier maintenance access, and standardized interfaces for modular installations.
Related standards
