Information technology - Data centre facilities and infrastructures - Part 30: Earthquake risk and impact analysis

Overview

ISO/IEC TS 22237-30:2022 is the Technical Specification on earthquake risk within the ISO/IEC 22237 series on data centre facilities. Its first edition was published on 23 March 2022 and runs to 20 pages. It specifies requirements and recommendations for the type of risk assessment to apply for seismic activity and earthquakes in relation to data centres. Because it is a technical specification rather than a standard, it is a reference with a lower binding status than a standard.

The specification also describes design concepts that can be used as mitigation actions in construction and other design elements. This content aims not only to identify the risk but to turn it into design decisions. Risk classes, threshold values and the steps of the method are therefore not covered here.

It is particularly relevant for regions of high seismicity such as Turkey. The record lists the Turkish Building Earthquake Code 2018 (TBDY 2018), ISO/IEC 22237-2 and EN 50600-2-1 among related documents. In design terms, the record suggests that when the site's seismic hazard (for example the TBDY 2018 map value) is significant, a seismic risk assessment step should be required and mitigation options offered.

The mitigation options suggested are base isolation, anchored racks, braced cable trays and flexible pipe joints, to be shown together with their cost and space impacts. This list comes from the design implications in the record, not from the specification itself. As a limit, the detailed requirements of the document were not read, and nothing here should be used as a binding selection without review by an engineer.

Key points

1. Specifies requirements and recommendations for the type of risk assessment for seismic activity and earthquakes at data centres.
2. Describes design concepts usable as mitigation actions in construction and other design elements.
3. Part of the ISO/IEC 22237 data centre facilities series.
4. Edition 1 Technical Specification, published 23 March 2022, 20 pages.
5. Particularly relevant for high-seismicity regions such as Turkey.
6. Related documents: Turkish Building Earthquake Code 2018, ISO/IEC 22237-2 and EN 50600-2-1.
7. Paid document; this summary uses only the publisher's public abstract.

Using it in design

• In the site module, require a seismic risk assessment step when the site's seismic hazard (e.g. TBDY 2018 map value) is significant.
• Offer mitigation options (base isolation, anchored racks, braced cable trays, flexible pipe joints) with their cost and space impacts.
• On projects in Turkey, record this specification as a complementary reference alongside TBDY 2018.
• Do not finalize the chosen mitigation measures without review by a seismic engineer.

Who should read it

Engineers and risk managers carrying out data centre site selection and structural design in high-seismicity regions.
