Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
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 ISO documents 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).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO 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).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

expressions related to conformity assessment, as well as information about ISO's adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see

This document was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 36,
Safety and impact testing.
This third edition cancels and replaces the second edition (ISO 15830-2:2013), which has been
technically revised.
The main changes are as follows:
— in Figure 1 head CG location has been changed to head reference mark location;
— body segment assembly mass specifications have been changed;
— clothing mass specification has been changed;
— in Table 1 specifications of head resultant acceleration have been changed for frontal and lateral
drops;
— in Table 3 new neck torsion specifications were added for new neck torsion validation test procedure;

ISO 15830-2:2022(E)
Introduction
The purpose of the ISO 15830 series is to document the design and specifications of this side-impact
dummy in a form suitable and intended for worldwide use.
In 1997, the WorldSID 50th percentile adult male dummy development was initiated, with the aims
of defining a global-consensus side-impact dummy, with more humanlike anthropometry, improved
biofidelity, and increased injury monitoring capabilities, suitable, for example, for regulatory use.
Participating in the development were research institutes, dummy and instrumentation manufacturers,
governments and vehicle manufacturers from around the world.
This document is intended to document information and design changes which have become available
since the publication of the second edition of the ISO 15830 series (2013-05-15).
In order to apply the ISO 15830 series properly, it is important that all four parts be used together.
