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).

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 15830-3:2013), which has been

technically revised.
The main changes are as follows:
— in Table 1 mounting specifications have been removed;
— in Table 1 specifications for sensor masses have been added;
— in Table 1 angular rate sensor has been added for the head, spine, and pelvis;

— in Table 1 rotational accelerometer has been replaced by angular accelerometer for the head, spine,

and pelvis;

— in Table 1 IR-TRACC has been replaced by multidimensional measurement system for the shoulder,

thorax, and abdomen;
— in Table 1 full arm sensors have been removed;
— in Table 1 ankle angular displacement sensor has been removed;

— in 4.1.3 all references to specific brands and models of sensors have been removed;

— in 4.2 DAS mass and mass distribution have been replaced by CAD targets for C.G. and mass moment

of inertia for the thorax, pelvis, and upper leg assemblies;
— calculation method of distances from IR-TRACC voltage output has been removed;
— information regarding pin codes for connectors has been removed;

Introduction

This third edition of the ISO 15830 series has been prepared on the basis of the existing design,

specifications, and performance of the WorldSID 50th percentile adult male side-impact dummy. 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 regulatory 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.

The original WorldSID drawings were available in electronic format. The updates are not available.

In order to apply the ISO 15830 series properly, it is important that all four parts be used together.

4 Mechanical requirements for electrical subsystems
4.1 Permissible sensors
4.1.1 General

All sensor locations and the mechanical specifications are specified as “permissible” (i.e. optional)

because the decision to use or not to use a given sensor is to be left to the individual relevant regulatory

authorities, consumer information organisations, and research or test laboratories. In this way, a given

regulation (or laboratory protocol) can indicate which of the permissible sensor’s locations described

ISO 15830-3:2022(E)

in this part of the ISO 15830 series shall be used in a given test. See Clause A.1 for optional sensor

locations.

The following sensors may be installed in the dummy. If installed, they shall comply with the mechanical

specifications in the subclause given in Table 1 and the mass specifications given in Table 1. If these

sensors are not installed, then structural or mass replacements shall be installed in the dummy in

accordance with ISO 15830-4.
Refer to Clause A.2 for information on sensor handling.

The mass of the angular rate sensor mount is 38 g and the mass of a single-axis sensor is 2 g.

The mass of an angular accelerometer single-axis sensor is 35 g.

This is the minimum number of channels to fulfil the requirements of a multidimensional measurement system.
