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
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. 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.
The committee responsible for this document is ISO/TC 22, Road vehicles, Subcommittee SC 12, Passive
safety crash protection systems.
This second edition cancels and replaces the first edition (ISO 15830-3:2005) which has been technically
revised. Technical amendments have been incorporated throughout all four parts, resulting from
extensive experience with the International 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

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 regards 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 this part of ISO 15830 will be required for their tests.
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.

INTERNATIONAL STANDARD ISO 15830-3:2013(E)
Road vehicles — Design and performance specifications for
the WorldSID 50th percentile male side-impact dummy —
Part 3:
Electronic subsystems
1 Scope
This part of ISO 15830 specifies requirements for electronic components of the WorldSID 50th percentile
side-impact dummy, a standardized anthropomorphic dummy for side-impact testing of road vehicles. It
is applicable to impact tests involving
— passenger vehicles of category M and goods vehicles of category N ,
1 1
— impacts to the side of the vehicle structure,
— impact tests involving the use of an anthropometric dummy as a human surrogate for the purpose
of evaluating compliance with vehicle safety standards.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated
references, the latest edition of the referenced document (including any amendments) applies.
ISO 6487, Road vehicles — Measurement techniques in impact tests — Instrumentation
ISO 15830-1, Design and performance specifications for the WorldSID 50th percentile male side-impact
dummy — Part 1: Terminology and rationale
ISO 15830-2:2013, Design and performance specifications for the WorldSID 50th percentile male side-
impact dummy — Part 2: Mechanical subsystems

SAE J1733, Sign convention for vehicle crash testing
3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 15830-1 apply.
4 Electrical subsystems requirements
4.1 Permissible sensors
4.1.1 General
NOTE All sensors 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 sensors described in this part of ISO 15830 must be used in a given test. It should also be noted that
different connector configurations may be found in different WorldSID assemblies.

5 Methods
5.1 Calculation of IR-TRACC distances from the IR-TRACC voltage outputs
If the permissible IR-TRACC is installed, deflections based on IR-TRACC voltage measurements shall be
calculated as follows:
1) Record the voltage signal from the IR-TRACC. Do not remove the zero offset.
2) Calculate
