Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are
members of ISO or IEC participate in the development of International Standards through technical
committees established by the respective organization to deal with particular fields of technical
activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international
organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the
work.
The procedures used to develop this document and those intended for its further maintenance
are described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria
needed for the different types of document should be noted. This document was drafted in
accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives or
www.iec.ch/members_experts/refdocs).
Attention is drawn to the possibility that some of the elements of this document may be the subject
of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent
rights. Details of any patent rights identified during the development of the document will be in the
Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents) or the IEC
list of patent declarations received (see https://patents.iec.ch).

Introduction
Parts 1, 3, 4 and 5 of the ISO/IEC 22237 series specify requirements and recommendations for the
design of data centres to meet a given Availability Class. Parts 2 and 6 of the ISO/IEC 22237 series
specify requirements and recommendations for the building construction and security systems for
data centres.
Determination of the risk and scale of seismic activity should be included as part of the overall risk
assessment approach found in ISO/IEC 22237-1. ISO/IEC TS 22237-2 requires a geographical risk
analysis which includes seismic activity and relevant mitigation actions, but does not identify the
specific actions to be applied. ISO/IEC TS 22237-6 addresses external environmental events but does
not explicitly list earthquakes or seismic activity within that group of events (other than general
vibration) or indicate the specific measures required.
Taking these points into consideration, this document provides requirements and recommendations
for the type of risk assessment to be employed in the context of seismic activity and earthquakes in
relation to data centres. It also describes design concepts that can be employed as mitigation actions
within the construction, and other design elements, of data centres.
