Overview

IEC 61587-5:2013 is an International Electrotechnical Commission (IEC) standard that focuses on the seismic testing of mechanical structures for electronic equipment. Specifically, it addresses chassis, subracks, and plug-in units conforming to the IEC 60297 and IEC 60917 series. The standard defines physical integrity requirements to ensure survivability and functionality of these mechanical components during and after seismic events such as earthquakes.

This standard applies exclusively to the mechanical structures of electronic equipment - not the internal electronic components or systems. By establishing robust seismic test requirements, IEC 61587-5:2013 aims to provide manufacturers, designers, and end-users with a reliable methodology for evaluating the earthquake resistance of chassis, subracks, and plug-in units across varying mass categories.

Key Topics

Scope and Object: The standard defines test criteria for mechanical structures, aiming to maintain operational capability post-earthquake. It excludes electronic parts and focuses on equipment sizes and weight categories.
Mass Categories and Application-Specific Load Distribution: Testing accounts for different weight categories, and the mass distribution within racks or chassis is defined as “intended use” to simulate real-world applications.
Seismic Test Methods:
- Single-axis acceleration testing involves vibration along a single direction.
- Tri-axial acceleration testing applies vibration simultaneously in three orthogonal axes, better simulating actual seismic motion.
Test Setup and Instrumentation: Detailed procedures for mounting specimens on vibration tables, simulating loads, and monitoring mechanical response to vibrations are provided.
Acceptance Criteria: The standard specifies thresholds and conditions under which mechanical integrity is deemed satisfactory after seismic testing.

Applications

IEC 61587-5:2013 plays a critical role in industries where electronic equipment is deployed in seismically active regions or where high reliability is mandatory, such as:

Telecommunications Networks: Ensuring that telecom racks, chassis, and modules maintain connectivity despite earthquakes.
Data Centers: Verifying that server racks and subracks sustain structural integrity to prevent downtime and hardware damage.
Industrial Automation and Control Systems: Protecting critical infrastructure electronics used in manufacturing, power plants, or transportation.
Military and Aerospace Equipment: Securing mechanical enclosures that house sensitive electronic units subjected to seismic or shock environments.

Implementing IEC 61587-5 helps manufacturers design resilient mechanical enclosures that withstand earthquake forces, reduces equipment failure risk, and supports compliance with regional seismic regulations.

IEC 60917 Series: Specifies mechanical structures for electronic equipment, including chassis and subracks.
IEC 61587-2: Covers seismic tests for cabinets and racks, providing foundational methodology from which IEC 61587-5’s tests for chassis and subracks are derived.
Regional Seismic Standards and Building Codes: While IEC 61587-5 provides mechanical testing methods for electronic equipment structures, it complements local building and seismic installation standards to ensure overall system resilience.
