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 3.
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.
In exceptional circumstances, when a technical committee has collected data of a different kind from that which is
normally published as an International Standard ("state of the art", for example), it may decide by a simple majority
vote of its participating members to publish a Technical Report. A Technical Report is entirely informative in nature
and does not have to be reviewed until the data it provides are considered to be no longer valid or useful.
Attention is drawn to the possibility that some of the elements of this Technical Report may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO/TR 9790, was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 12, Restraint
systems.
This first edition cancels and replaces the ISO/TR 9790 parts 1 to 6 (1989), which have been reviewed, updated
and organized into a single Technical Report.

TECHNICAL REPORT ISO/TR 9790:1999(E)
Road vehicles — Anthropomorphic side impact dummy — Lateral
impact response requirements to assess the biofidelity of the
dummy
1 Scope
This Technical Report describes laboratory test procedures and impact response requirements suitable for
assessing the lateral impact biofidelity of the head, neck, shoulder, thorax, abdomen and pelvis of crash test
dummies, subcomponent test devices, and math models that are used to represent a 50th percentile adult male.
The method used by ISO to determine an overall biofidelity rating for a given side impact surrogate has been added
to this Technical Report.
2 Biomechanical basis
The impact response requirements presented in this Technical Report are the result of a critical evaluation of data
selected from experiments agreed to by experts as being the best and most up-to-date information available. The
following describes the biomechanical data used to describe response requirements for the head, neck, shoulder,
thorax, abdomen and pelvis.
2.1 Head Tests
Two lateral head impact tests are defined. Head Test 1 is based on the rigid surface cadaver impacts conducted by
Hodgson and Thomas (1). Head Test 2 is based on the padded surface cadaver impacts of the Association
Peugeot-Renault (APR) (2). Padded surface impact tests of Hodgson and Thomas (1), McElhaney et al. (3),
Nahum et al. (4), Nahum et al. (5), Schneider et al. (6) and Got et al. (7) were not used since either the padding
characteristics were not specified or a given piece of padding was subjected to multiple impacts, changing its
response characteristics. Detailed discussions of the influences of these factors on head acceleration data are
given by Mertz (8), Mertz et al. (9) and Mertz (10). The rigid surface impacts of McElhaney et al. (3) were not used
because the impact velocities were not given for each test. The rigid surface impact data of Got et al. (7) were not
used since significant skull fractures were produced.
