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 lnternati Standards adopted by the technical co mmittees are circulated to the member bodies for votin

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 based on accident data.
It is intended that the methods and recommendations contained in this International Standard should be used in all
However, researchers should also consider variations in the specified conditions (for
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.
International Standard properly, it is strongly recomme nded
In order to apply this that all eight parts be used

Part 6:
Full-scale impact-test procedures
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;
- 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 minimum requirements for
- paired comparison tests;
- the preparation of the dummy, motor cycle, and opposing vehicle;
- the repeatability and reproducibility of impact test conditions within and between test sites;
- the minimization of variation in secondary test variables;
- realistic and representative impact conditions for full-scale impact tests;
- a means to verify analytical evaluations of proposed rider crash protective devices fitted to motor cycles,
such as computer simulation.
This International Standard does not apply to testing for regulatory or legislative purposes.

5 Impact test methods
.
51 Impact conditions
From the list of required and other, permissible impact configurations given in 4.3 of IS0 13232-2, select the impact
configuration to be tested and specify the impact conditions using the variables described in IS0 13232-2.
5.2 Vehicle set up
5.2.1 Opposing vehicle
Remove the battery cable and fuel. Weigh the vehicle. Weigh the brake actuator system and the portion of the
guidance system mounted on the OV. Add this mass to the measured OV mass and compare the total mass to the
allowable test mass given in 4.1. Add or remove ballast or components as necessary to attain the allowable test
mass. Install the brake actuator and guidance systems in the OV.
Leave the steering wheel and steering system free to steer. Put the transmission in neutral gear. Completely close
all doors, windows , the bonnet, and the boot lid.
Measure and adjust the ride height to that which is specified in table 3. Adjust the ride height by adju sting any of
the tyre pressures to between 138 kPa and 276 kPa, or by adding sp ring spacers and/or compressors.

5.2.2 Motor cycle
Remove the fuel. If the MC is equipped with a rear wheel adjuster to accommodate a chain or belt, adjust the rear
wheel to the most forward position. Remove the chain or belt, if present. Set the tyre pressures to the vehicle
manufacturer ’s recommendations. Set the suspension ride height and damping settings to the vehicle
manufacturer ’s recommendations, or to the mid-range point, in the absence of a recommendation. Weigh the MC.
Put the MC in neutral gear.
For impact configurations in which the overall MC length measurement is required (e.g., 143-9,8/O in IS0 13232-2),
place the dummy on the motor cycle in a riding position which approximates that to be used in the full-scale impact
tests, with the hands on the hand grips and the feet on the foot rests.
Ballast the motor cycle to simulate the mass
of any additional equipment related to the conduct of the test. Place a bump, like the one shown in figure 1,
approximately I,5 m in front of the MC, such that the bump is perpendicular to the MC longitudinal centre line. Roll
the laden MC a total distance of at least 3 m, perpendicularly across the bump. Place a target on the intended MC
contact point and document the MC overall length as specified in clause 6. Remove the dummy from the MC.
For impact configurations in which the MC is moving, install the MC in the guidance system, such that
is free to ter release from the guidance
- the steering system steer af system and prior to impact, except for
interaction with the dummy ’s hands;
- the front wheel is pointed in the straight ahead direction;
- the front and rear facing MC upper and lower centre line targets form a vertical line with respect to gravity.
For impact configurations where the MC is stationary, construct two wooden support stands with a nominally
square cross section; a maximum length and width of 50 mm; and of suitable height to support the MC in a vertical
position. Use metal shims having a maximum outside diameter of 25 mm and a maximum thickness of 2 mm, on
top of each support stand to level the MC on the stands.
5.3 Dummy set up
5.3.1 Sensor, data acquisition, and post processing systems verification
Mark the dummy head skin with the impactor target point and line-of-motion centre as indicated in figure 2. Seat
the dummy on a rigid, flat, horizontal surface with the thoracic spine box, upper arms, and lower legs in a vertical
orientation. Adjust the lower neck adjustment joint so that with the helmet alignment tool (shown in figure D.l)
fitted to the front of the head, the helmet alignment tool upper edge is horizontal, + 2O with respect to gravity.
Pitch the dummy torso/head assembly forward about the hip joints by adjusting the lateral separation of the legs, if
necessary, so that the helmet alignment tool upper edge is inclined 45’ + 2O from horizontal.
