Foreword
IS0 (the International Organization for Standardization) is a worldwide federation of national standards bodies (IS0
member bodies). The work of preparing International Standards is normally carried out through IS0 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. IS0 collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
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.
This part of IS0 13232 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 22,
Motorcycles.
At the request of the United Nations Economic Commission for Europe, Group for Road Vehicle General Safety
(UN/ECE/TRANS/SCI/WP29/GRSG), this International Standard has been prepared by ISOnC 22/SC 22,
Motorcycles, as eight interrelated parts, on the basis of original working documents submitted by the International
Motorcycle Manufacturers Association (IMMA).
This is the first version of the standard.
IS0 13232 consists of the following parts, under the general title Motorcycles - Test and analysis procedures for
research evaluation of rider crash protective devices fitted to motorcycles:
Part 1: Definitions, symbols and general considerations
- Part 2: Definition of impact conditions in relation to accident data
Part 3: Anthropometric impact dummy
Part 4: Variables to be measured, instrumentation and measurement procedures
Part 5: Injury indices and risk/benefit analysis
- Part 6: Full-scale impact-test procedures
- Part 7: Standardized procedures for performing computer simulations of motorcycle impact tests
Part 8: Documentation and reports
Annex A forms an integral part of this part of IS0 13232. Annex B is for information only.

Introduction
This International been prepared on the basis of exist ing technology.
Standard has Its purpose is to define common
research methods for making an overall evaluatio In of
and a means the effect that d evices whit h are fitted to motor
of riders,
cycles and intend ed for the crash protection have on injuries, when assessed over a range of impact,
conditions which are ba sed on accident data
It is intended that the methods and recommendations contained in this International Standard should be used in all
basic feasibility research. However, researchers should also consider variations in the specified conditions (for
example, rider size) when evaluating the overall feasibility of any protective device.
In addition, researchers may
wish to vary or extend elements of the methodology in order to research issues which are of particular interest to
them. In all such cases which go beyond the basic research, if reference is to be made to this International
Standard, a clear explanation of how the procedures used differ from the basic methodology should be provided.
In order to this International Standard properly, it is strongly recommended that ail eight parts be used
apply
together, p larticul arly if the results are to be published.
To the extent, if any, that any products identified in this International Standard may be subject to patent rights, and
to the extent, if any, that licenses may be available relative to such patents, potential manufacturers of such
products are advised that individual patent inquiries should be made and alternative products considered. A record
of patent holders’ statements, if any, regarding their willingness to negotiate licenses under patent and like rights
with applicants throughout the world under reasonable terms and conditions, is on file with the IS0 Central
Secretariat.

Part 3:
Anthropometric impact dummy
1 Scope
This International Standard specifies minimum requirements for research into the feasibility of protective devices
fitted to motor cycles, which are intended to protect the rider in the event of a collision.
This International Standard is applicable to impact tests involving
- two wheeled motor cycles;
- the specified type of opposing vehicle;
- either a stationary and a moving vehicle or two moving vehicles;
- for any moving vehicle, a steady speed and straight line motion immediately prior to impact;
- one helmeted dummy in a normal seating position on an upright motor cycle;
- the measurement of the potential for specified types of injury, by body region;
- evaluation of the results of paired impact tests (i.e.,
comparisons between motor cycles fitted and not
fitted with the proposed devices).
This part of IS0 13232 specifies the minimum requirements for the
- biofidelity of the motor cyclist anthropometric impact dummy;
- compatibility of the dummy with motor cycles, helmets, multi-directional impacts, and the instrumentation;
- repeatability and reproducibility of the dummy properties and responses.
This International Standard does not apply to testing for regulatory or legislative purposes.
2 Normative references
The following standards contain provisions which, through reference in this text, constitute provisions of this
International Standard. At the time of publication, the editions indicated were valid. All standards are subject to
revision, and parties to agreements based on this part of IS0 13232 are encouraged to investigate the possibility of
applying the most recent editions of the standards indicated below. Members of IEC and IS0 maintain registers of
currently valid International Standards.

5.1 Initial conformity of production
For certification of any new design, material specification, or manufacturing process of any frangible component and
for each of the test methods described in clause 6, ten unused components shall be tested to establish estimates of
the sample ’s mean and standard deviation. For example, certification of three different test methods would require
30 components to be tested. The sample mean value shall be within + 5% of the specified value for all strengths
The sample mean value shall be within + 20% of the specified value for all
and abdominal insert static forces.

and abdominal insert static forces. The sample standard deviation shall be less than 10% of the sample mean value
for all static deflections.
5.2 Subsequent conformity of production
Once a specific design, material specification, and manufacturing process have been certified, three components
from each lot which is identically manufactured shall be tested to verify the applicable characteristics specified in
table 5.

If none of the components deviates by more than two standard deviations, as defined in 5.1, from the established
mean value for the specified characteristic, the lot shall be considered acceptable for full-scale impact testing,
according to IS0 13232-6. If one or more of the tested components deviate by more than two standard deviations,
as defined in 5.1, from the established mean value for the specified characteristic, a different sample of three
components from the same lot shall be tested. If more than two of the total sample of six components deviate by
more than two standard deviations, as defined in 5.1, from the established mean values, the said lot shall not be
used for full-scale impact testing.

Using pins, attach rigid extensions of equal length, as shown in figure A.20, to each end of the frangible bone such
that the minimum combined length of the bone and extensions is as given in table 6. Support the specimen radially
