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.
Amendment 1 to ISO 13232-5:2005 was prepared by Technical Committee ISO/TC 22, Road vehicles,
Subcommittee SC 22, Motorcycles.

Part 5:
Injury indices and risk/benefit analysis
Amendment 1: Ground impact and injury costs
IMPORTANT This Amendment may require re-interpretation by users of numerous directly related
clauses among the eight parts of ISO 13232. It is expected that consequential amendments to these
clauses would be part of any future revision of ISO 13232.
Page 2, Clause 3
Add the following terms:
— economic costs;
— comprehensive costs;
— quality adjusted life costs;
Page 23, 5.9
Insert the following at the beginning of the subclause and before the Note.
“The risk/benefit analysis for each collision shall include, at a minimum, the primary impact period, which shall
be considered to be the time period until but not including ground impact, or 0,500 s after the first MC/OV
contact, whichever is sooner.
The risk/benefit analysis for each collision should also include a separate analysis for the entire impact
sequence, which shall be considered to be the time period from first MC/OV contact until at least 1 s and no
longer than 3 s after the first MC/OV contact, and to the extent applicable, within this period, until the dummy’s
head, spine, and pelvis centres-of-gravity resultant velocities are all less than 1 m/s, or until 500 ms after
ground impact, whichever is sooner.
Ground impact shall be considered to be the first point in time when any portion of the dummy’s head or helmet
shapes is in contact with the ground.”
Page 153, O.3.8
Insert the following at the beginning of O.3.8:
“Injuries resulting from ground contact are often a substantial portion of the total injuries in MC/OV crashes
(e.g., ACEM, MAIDS Report, 2004). Advances in computational speeds have made it feasible to conduct
computer simulation analyses that include ground contact. However, in order to place reasonable upper limits
on the computational requirements for simulations that include the ground contact period, the simulation is
considered to be complete when the dummy’s velocities are nearly zero or 500 ms after head or helmet to
ground impact, whichever is sooner. In order to account for cases in which, during the first 3 s after MC/OV
contact, the dummy’s key body region velocities are not reduced to nearly zero and the dummy’s head or
helmet does not impact the ground, the simulation may be considered to be complete after 3 s.
ISO 13232-5:2005/Amd.1:2012(E)
These upper limits on the required duration of the computer simulation allow virtually all important injuries to
be included in the risk/benefit analysis without requiring excessive computer time. Using typical contemporary
(i.e., 2008 production) personal computers, simulations of the primary impact period for the 2 X 200 impact
configurations using an example fully ISO-compliant multi-body model (Kebschull et al, 1998) can be run in
approximately 8 CPU hours. Extending the simulation time to include the entire impact period as described in
subclause 5.9 requires less than 48 CPU hours. In cases where the researcher wishes to model higher levels
of detail, it is expected that finite element models would require less than 10 000 CPU hours to simulate the
primary impact period for these 2 X 200 impact configurations and less than 60 000 CPU hours to simulate the
entire impact period. Hybrid multi-body/FE models would require CPU hours somewhere between those for a
pure multi-body model and for a pure finite element model. Another technological advance that enables such
computational loads to be feasible is the increasingly popular usage of ”computer clusters” or “computer grids”
for processing, i.e., involving many CPUs, running in parallel.”

based on ancillary costs. Document changes are as follows:

5.5.3 Quality adjusted life costs
Tabulate the injuries by body region and AIS injury severity level. Determine the quality adjusted life costs
associated with each body region injury and each discrete AIS injury severity level, for each country in the cost
data listed in Annex A. Calculate the total quality adjusted life cost associated with the injuries for each of the
four body regions, including the head, neck, thorax, and abdomen, using the equation given below:

Insert the following at the beginning of the subclause and before the Note.
“The risk/benefit analysis for each collision shall, at a minimum, include the primary impact period, which is
the time period up to but not including dummy to ground contact, or 0,500 s after the first MC/OV contact,
whichever is sooner. The risk/benefit analysis for each collision should also include a separate analysis for the
entire impact sequence, which is defined as the time period from first MC/OV contact until the dummy’s head,
spine, and pelvis velocities are all less than 1 m/s or until 500 ms after ground impact, whichever is sooner.
Ground impact is defined as the first point in time when any portion of the dummy’s head or helmet is in contact
with the ground. The entire impact sequence shall be at least 1 s and shall be no longer than 3 s after the first
MC/OV contact.”
