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 15830-3 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 12,
Passive safety crash protection systems.
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

Introduction
This first edition of ISO 15830 (all parts) has been prepared on the basis of the existing design, specifications
th
and performance of the WorldSID 50 percentile adult male (PAM) 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 PAM 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, the
respective parties will need to define which of the permissive 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.

Road vehicles — Design and performance specifications for
the WorldSID 50th percentile male side-impact dummy —
Part 3:
Electronic subsystems
1 Scope
th
This part of ISO 15830 specifies requirements for electronic components of the WorldSID 50 percentile side
impact dummy, a standard anthropomorphic dummy for side impact testing of road vehicles. It is applicable to
impact tests involving:
⎯ passenger vehicles of categories M1 and goods vehicles of categories N1,
⎯ impacts to the side of the vehicle structure, and
⎯ impact tests involving the use of an anthropometric dummy as a human surrogate for the purpose of
evaluating compliance with vehicle safety standards.

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 International Standard must be used in a given test.
The following sensors may be installed in the dummy. If installed, they shall comply with the specifications
given in Table 1. If these sensors are not installed, then structural or mass replacements shall be installed in
the dummy.
