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. www.iso.org/directives
Attention is drawn to the possibility that some of the elements of this document may be the subject of

Introduction
This second edition of ISO 15830 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, ISO/TC22/SC12 initiated the WorldSID 50th percentile adult male dummy development,
with the aims of defining a global-consensus side-impact dummy, having a wider range of humanlike
anthropometry, biofidelity, and injury monitoring capabilities, suitable for regulatory use. Participating
in the development were research institutes, dummy and instrumentation manufacturers, governments,
and vehicle manufacturers from around the world.
With regard to potential regulatory, consumer information, or research and development use of
ISO 15830, users will need to identify which of the permissive (i.e. optional) sensors and other elements
defined in ISO 15830-3 are to be used in a given application.
WorldSID drawings in electronic format are being made available. Details are given in
ISO 15830-2:2013, Annex B.
In order to apply ISO 15830 properly, it is important that all four parts be used together.

3, 4, and 5. When mounted for lateral drops, position the head such that its midsagittal plane has an
angle of 35° ± 1° with the impact surface and its anterior-posterior axis is horizontal to within 1°.
— Suspend the head above the drop table using the head drop tool and a quick release mechanism.
— For lateral tests, position the head so its lowest point is 200 mm ± 0,25 mm above the impact surface
and drop the head.
For a frontal test, position the head so the lowest point on the forehead is 376 mm ± 0,25 mm above the
impact surface.

— Attach the top of the neck to the head form.
— Attach the bottom of the neck to the pendulum interface. Ensure that the screws do not protrude
into the neck rubber as this may influence the response. If the screws are too long, insert washers
under the head of the screw in order to prevent rubber contact. Mount the pendulum interface to the
pendulum such that the head form’s midsagittal plane is vertical and is perpendicular to the plane
of motion of the pendulum’s longitudinal centreline.
— Slide the carbon fibre rods through the potentiometer housings on the pendulum. First, slide the
pivot of the potentiometer closest to the pendulum over the central steel rod in the head form, then
install the small spacer ring and the second pivot. Carefully tighten the second pivot.

ISO/DIS 15830-2
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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 15830-2 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 12,
Passive safety crash protection systems.
This second edition cancels and replaces the first edition (ISO 15830-2:2005) which has been technically
revised. Technical amendments have been incorporated throughout all four parts, resulting from extensive
experience with the standard and design changes.
ISO 15830 consists of the following parts, under the general title Road vehicles — Design and performance
specifications for the WorldSID 50th percentile male side impact dummy:
 Part 1: Terminology and rationale
 Part 2: Mechanical subsystems
 Part 3: Electronic subsystems
 Part 4: User's manual

ISO/DIS 15830-2
Introduction
This first edition of ISO 15830 has been prepared on the basis of the existing design, specifications and
th
performance of the WorldSID 50 percentile adult male side impact dummy. The purpose of ISO 15830 is to
document the design and specifications of this side impact dummy in a form suitable and intended for
worldwide regulatory use.
th
In 1997, ISO/TC22/SC12 initiated the WorldSID 50 percentile adult male dummy development, with the aims
of defining a global-consensus side impact dummy, having a wider range of human-like anthropometry,
biofidelity and injury monitoring capabilities, suitable for regulatory use. Participating in the development were
research institutes, dummy and instrumentation manufacturers, governments, and vehicle manufacturers from
around the world.
With regard to potential regulatory, consumer information or research and development use of ISO 15830,
users will need to identify which of the permissive (i.e., optional) sensors and other elements defined in Part 3
are to be used in a given application.
In order to apply ISO 15830 properly, it is important that all four parts be used together.
