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 ISOK 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/VVP29/GRSG), this International Standard has been prepared by ISO/TC 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
Annexes A, B, C and D form an integral part of this part of IS0 13232. Annexes E and F are for information only.

Introduction
This International Standard 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 motor
cycles 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 this International Standard should be used
However, researchers should also consider variations in the specified conditions (for
in all basic feasibility research.
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.
It is recognized that the method of analysis as described in this part of IS0 13232 may be modified at a future date
to reflect the availability of more detailed accident data bases which may be collected with a greater degree of
precision than were the Hannover and Los Angeles accident data.
In order to Intern Iational Standard properly it is strongly ret
apply this I ommen ded that all eight parts be used
together, p articularly if the results are to be publishe d.

Part 2:
Definition of impact conditions in relation to accident data
1 Scope
This International Standard specifies the 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;
comparisons between motor cycles fitted and not
- evaluation of the results of paired impact tests (i.e.,
fitted with the proposed devices).
This part of IS0 13232
- specifies minimum requirements for the collection and analysis of motor cycle accident data, in order to
provide a statistical basis for defining impact test conditions;
- provides a standardized and representative set of accident data and a set of impact conditions based on an
analysis of this accident data.
This International Standard does not apply to testing for regulatory or legislative purposes.

the following general rules:
- OV corner contact points shall be the 45’ tangent points, as shown in figure 1;

- MC front contact point shall be such that the projection of the MC centre line, forward of the foremost part
of the front wheel, at first contact between any portion of the MC or dummy and the OV, intersects a
vertical line through the specified OV contact point;

part of the rear wheel, at first contact between any portion of the MC or dummy and the OV, intersects a
vertical line through the specified OV contact point;
- MC side contact shall use the conventions given in 4.3.1 and shown in figure 1 (i.e., for OV front or rear
contact use the 143-9.8/O type of geometry; for OV corner contact use the 225-O/1 3,4 type of geometry);
- The relative heading angles shall be at the nominal values defined in table 2 and figure 4.
For testing purposes, the impact geometry may be reflected about the OV centre line (e.g., E45 instead of 225).

5 Analysis methods
5.1 Using accident data to determine frequency of occurrence of various impact configurations
Sort the accident data as described below.
5.1 .I Sub-sample definition
Combine the databases listed in annex C. From the combined, overall database, select all of the cases which have
all of these conditions:
- passenger car impact;
- single rider;
- seated rider.
5.1.2 Categorization
For each case selected in 5.1.1, and for each impact variable, determine within which cell range the case lies and
assign code numbers for the OV and MC contact points and relative heading angle, and nominal values for the OV
and MC speeds, based on tables 2 and 3 and figures 2, 3, and 5.
5.1.3 Sorting
Sort all the subsample accident data into a matrix describing the combinations of the above cells. Determine the
number of accidents which lie within the boundaries of each of the cells.
If the OV contact point involves the left side of the OV, then reclassify the OV and MC contact points and relative
reclassify all accidents that occur in the sorted geometry codes to
heading angle according to table 4. In addition,
the reclassified geometry codes as listed in table 5, in order to resolve minor inconsistencies which may be present
in the original accident data.
Remove all accidents in the cells listed in table 6 which, as a result of categorization, correspond to untestable
configurations.

5.1.4 Representation
Associate the number of accidents (frequency of occurrence) in each cell with the OV and MC contact point codes,
relative heading angle codes, and OV and MC speed nominal values which will be considered to represent each cell.
5.2 Using accident data to determine frequency of injury by body region and injury type of
various impact configurations
Sort the accident data using the same method as described in 5.1, except determine the number of accidents which
have at least one injury of the selected body region, injury type and severity which lie within the boundaries of each
of the cells. A recommended list of body regions and injury types and severities is included in annex A.
Perform the analysis for the following injuries:
- head concussions, AIS 2 2;
- upper *leg fractures, AIS r 2;
- lower leg fractures, AIS 2 2.
For head concussion injuries, only include in the sorting process accidents where a helmet was worn.

Example accident data
Table C.l defines the column headings and units used in tables C.2 and C.3. The Los Angeles example data are
given in table C.2. The Hannover example data are given in table C.3. These are the original data and are
presented in non-% units (miles per hour).
