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.
International Standard IS0 10997 was prepared by Technical Committee
lSO/TC 22, Road vehicles, Subcommittee SC 10, impact test procedures.
Annex A forms an integral part of this International Standard.

1 Scope
This International Standard describes a full scale test method for side (lateral) impact testing of passenger cars as
defined in IS0 3833 with a front seat dummy. It is intended to facilitate uniform testing at different test facilities.
2 Normative references
The following standards contain provisions which, through reference in this text, constitute provisions of this

3 Definitions
For the purposes of this International Standard, the following definitions apply.
3.1 movable deformable barrier, MDB: Energy-absorbing movable barrier used to impact either side of the test
vehicle.
3.2 impact point: Point marked on the side of the test vehicle as the target to be impacted by a selected point
on the MDB.
4 Test facility and equipment
4.1 Impact test site
The impact test site shall be a level, smooth and hard surface which is of sufficient area for the MDB to reach the
specified speed prior to impact and to permit deceleration by the MDB and the test vehicle while remaining on the
surface of the test site.

---------------------- Page: 3 ----------------------
@ IS0
IS0 10997:1996(E)
The surface immediately on the impacted side of the stationary test vehicle shall be horizontal, flat and smooth for
a length of at least 10 m in the direction of impact. There shall be no more than 1 % slope measured over a 1 m
length for at least the last 10 m.
4.2 MDB characteristics
The MDB shall have an energy-absorbing face to represent the crush characteristics of the front of an average
passenger car. The dimensions of the energy-absorbing impactor face shall be
width 1 500 mm + 20 mm
height 500mm~lOmm
depth 440 mm min.
surface two flat parallel faces offset 60 mm + 5 mm
Horizontally adjacent block faces shall lie in the same vertical plane within + 5 mm.
The ground clearance at the lower edge of the MDB face shall be 260 mm & 10 mm.
This layout is shown in figure 1. The deformation and the energy-absorbing characteristics of the impactor face and
each of its six blocks are shown in figures 2 and 3.
The carriage to which the energy-absorbing MDB face is attached is shown in figure 4. The vertical plane of
symmetry of the MDB face shall be coincident with the longitudinal vertical plane of the carriage with a tolerance
of +, 10 mm.
The total mass of the MDB face, carriage and ballast as necessary shall be 1 100 kg + 10 kg.
4.3 lmpactor calibration
The supplier of the MDB face shall provide a certificate of calibration. The supplier shall also provide an analysis of
his product’s conformance to the calibration requirements. The calibration procedure is defined in annex A. The
performance characteristics of the MDB face are acceptable if each block and the entire face fall within the force-
deflection corridors shown in figure 2. Alternatively the performance characteristics are acceptable if each block
and the entire face fall within the energy-deflection corridors shown in figure 3.

4.4 Propulsion of MDB
The MDB shall be towed to a point no closer than 0,5 m from contact with the test vehicle, at which point it shall
be released to travel freely. The MDB shall not be braked until after 200 ms from the time of contact. At the
moment of impact, the MDB shall be moving at the prescribed velocity.
4.5 Impact point on test vehicle
The test vehicle may be impacted from either side. The impact point shall be visibly marked on the outside of the
test vehicle.
The transverse plane of the vehicle passing through the R-point, as defined in IS0 6549, of the front seated
occupant shall be coincident with the longitudinal median vertical plane of the MDB.
The maximum offset between the MDB and prescribed impact point shall be k 30 mm.
The ground clearance at the lower edge of the MDB face, at the time of impact, shall be 260 mm + 10 mm.
4.6 Angle of impact
The side impact shall be performed at an impact angle of 90’ as shown in figure 5.
At the time of impact, the face of the MDB shall be parallel to the longitudinal centreline of the test vehicle with a
maximum angular deviation of 3’.

4.7 Tolerances on impact speed
The impact speed shall be measured within 0,5 m of the test vehicle. The impact speed tolerance shall be + 1 % of
the desired speed.
5 Preparation of test vehicle
Mass of test vehicle
5.1
The vehicle test mass, mt, shall be calculated as follows:
mt = lSO-MO6 + ml + md
where
ISO-MO6 is as defined in IS0 1176:1990, definition 4.6, in kilograms;
ml is rated cargo and luggage mass, in kilograms, equal to
ISO-MO9 - (68 kg x DSC)
in which
ISO-MO9 is as defined in IS0 1176:1990, definition 4.9, in kilograms,
DSC is the designated seating capacity of the test vehicle;
md is the test dummy mass.
The vehicle shall be ballasted to achieve the test mass to within + 10 kg. The ballast shall be located and secured to
the vehicle so that it does not alter the structural characteristics of the impacted side of the vehicle.

IS0 10997:1996(E)
At the time of impact, the vehicle shall be at the normal ride height and attitude with the engine idling and with the
mass equivalent to two 50th percentile adult male front occupants. This height and attitude shall be as defined by
the manufacturer.
The instrumentation and cameras required for testing shall not change the axle mass ISO-Ml 1 (see IS0 117&l 990,
definition 4.11) by more than 20 kg.
5.2 Condition of test vehicle
The test vehicle shall be stationary. The doors shall be fully closed and latched, but not locked The wrndow
adjacent to the test dummy shall be closed, with the glass in place.
Adjustable seats shall be in the adjustment position midway between the foremost and rearmost positions, and, if
separately adjustable in a vertical direction, at the position defined by the manufacturer. If on the same model
adjustable and fixed seats exist, the vertical position of the fixed seat shall be used. If an adjustment position does
not exist midway between the foremost and rearmost positions, the adjustment position closest to the rear of the
midpoint shall be used.
