Motorcycles — Test and analysis procedures for research evaluation of rider crash protective devices fitted to motorcycles — Part 3: Motorcyclist anthropometric impact dummy
ISO 13232-3:2005 specifies the minimum requirements for the: biofidelity of the motorcyclist anthropometric impact dummy; compatibility of the dummy with motorcycles, helmets, multi-directional impacts, and the instrumentation; and repeatability and reproducibility of the dummy properties and responses. ISO 13232 specifies minimum requirements for research into the feasibility of protective devices fitted to motorcycles, which are intended to protect the rider in the event of a collision. ISO 13232 is applicable to impact tests involving: two-wheeled motorcycles; 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 motorcycle; the measurement of the potential for specified types of injury, by body region; and evaluation of the results of paired impact tests (i.e. comparisons between motorcycles fitted and not fitted with the proposed devices). ISO 13232 does not apply to testing for regulatory or legislative purposes.

ISO 13232-3:2005(E)
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.
ISO 13232-3 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 22, Motorcycles.
This second edition cancels and replaces the first version (ISO 13232-3:1996), which has been technically revised.
ISO 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: Motorcyclist 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

ISO 13232-3:2005(E)
Introduction
ISO 13232 has been prepared on the basis of existing technology. Its purpose is to define common research
methods and a means for making an overall evaluation of the effect that devices which are fitted to motorcycles
and intended for the crash protection of riders, have on injuries, when assessed over a range of impact conditions
which are based on accident data.
It is intended that all of the methods and recommendations contained in ISO 13232 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 ISO 13232, a clear explanation of
how the used procedures differ from the basic methodology should be provided.
ISO 13232 was prepared by ISO/TC 22/SC 22 at the request of the United Nations Economic Commission for
Europe Group for Road Vehicle General Safety (UN/ECE/TRANS/SCI/WP29/GRSG), based on original working
documents submitted by the International Motorcycle Manufacturers Association (IMMA), and comprising eight
interrelated parts.
This revision of ISO 13232 incorporates extensive technical amendments throughout all the parts, resulting from
extensive experience with the standard and the development of improved research methods.
In order to apply ISO 13232 properly, it is strongly recommended that all eight parts be used together, particularly if
the results are to be published.
