ASSESSMENT PROTOCOL – ADULT OCCUPANT PROTECTION
1INTRODUCTION
Euro NCAP’s original assessment protocol was developed
jointly by TRL and Vehicle Safety Consultants Ltd under contract
to the UK Department of the Environment Transport and the
Regions and International Testing, respectively. Subsequent
versions of the protocol have been developed and released by
the Euro NCAP Secretariat. Beginning with Version 5 important
changes have been included that have been brought about by
the introduction of the overall rating scheme. Individual
documents are released for the four main areas of
assessment: ?Assessment Protocol – Adult Occupant Protection;
Assessment Protocol – Child Occupant Protection;
Assessment Protocol – Pedestrian Occupant Protection;
Assessment Protocol – Safety Assist;
In addition to these four assessment protocols, a separate
document is provided describing the method and criteria by
which the overall safety rating is calculated on the basis of the
car performance in each of the above areas of assessment.
The following protocol deals with the assessments made in
the area of Adult Occupant Protection, in particular in the frontal
impact test, the side impact test, the pole test and the whiplash
tests. DISCLAIMER: Euro NCAP has taken all reasonable care to
ensure that the information published in this protocol is accurate
and reflects the technical decisions taken by the organisation. In
the unlikely event that this protocol contains a typographical
error or any other inaccuracy, Euro NCAP reserves the right to
make corrections and determine the assessment and subsequent
result of the affected requirement(s).
2METHOD OF ASSESSMENT
The starting point for the assessment of adult occupant
protection is the dummy response data recorded in four different
test configurations: frontal impact, side impact, pole impact and
(low speed) rear impact. Initially, each relevant body area is given
a score based on the measured dummy parameters. These scores
can be adjusted after the test based on supplementary
requirements. E.g. for frontal impact, consideration is given to
whether the original score should be adjusted to reflect occupant
kinematics or sensitivity to small changes in contact location,
which might influence the protection of different sized occupants
in different seating positions. The assessment also considers the
structural performance of the car by taking account of such
aspects as steering wheel displacement, pedal movement, foot
well distortion and displacement of
Version 5.1 October 20094
the A pillar. The adjustments (or modifiers) based on both
inspection and geometrical considerations are applied to the
body area assessments to which they are most relevant.
For frontal impact, the score for each body area is based on
the driver data, unless part of the passenger fared less well. It is
stated that the judgement relates primarily to the driver. Side
impact and pole impact results relate to the struck-side occupant
only, while Whiplash results are valid for any front seat adult
occupant. No attempt is made to rate the risk of life threatening
injury any differently from the risk of disabling injury. Similarly,
no attempt is made to rate the risk of the more serious but less
frequent injury any differently from the risk of less serious but
more frequent injury. Care has been taken to try to avoid
encouraging manufacturers to concentrate their attention on
areas which would provide little benefit in accidents.
From the information collected in the four test scenarios,
individual test scores are computed for frontal, side and pole
impact and whiplash protection. The adjusted score for the
different body regions is presented, in a visual format of coloured
segments within a human body outline. This is presented for the
driver and front seat passenger in frontal impact, for the driver in
side and pole impact and for the driver or passenger in rear
impact. Finally, for the complete area of adult occupant
protection assessment, the scores for frontal, side, pole and
whiplash are summed. The resulting Adult Occupant Protection
Score is expressed as a percentage of the maximum achievable
number of points.
In addition to the basic Euro NCAP assessment, additional
information is recorded and may be reported. In future, some of
these additional aspects may be added to the Euro NCAP
assessment.
2.1Points Calculation
From Phase 3, a sliding scale system of points scoring has
been used to calculate points for each measured criterion. This
involves two limits for each parameter, a more demanding limit
(higher performance), below which a maximum score is obtained
and a less demanding limit (lower performance), beyond which
no points are scored. In frontal, side, pole and rear* impacts, the
maximum score for each body region is four points. Where a
value falls between the two limits, the score is calculated by linear
interpolation.
For all tests part of the adult occupant protection assessment,
capping limits are maintained for criteria related to critical body
regions. Exceeding a capping limit generally indicates
unacceptable high risk at injury or, in the case of the whiplash
test, an unacceptably high seat design parameter. In all cases, this
leads to loss of all points related to the tests. Capping limits can
be equal to or higher than the lower performance limit,
depending on the test.
* Neck only based on a combination of scores obtained in
three individual test conditions.

53 FRONTAL IMPACT ASSESSMENT
3.1 Criteria and Limit Values
The basic assessment criteria used for frontal impact, with
the upper and lower performance limits for each parameter, are
summarised below. Where multiple criteria exist for an individual
body region, the lowest scoring parameter is used to determine
the performance of that region. The lowest scoring body region
of driver or passenger is used to determine the score. For frontal
impact, capping is applied on the critical body regions: head,
neck and chest.
3.1.1 Head
3.1.1.1 Drivers with Steering Wheel Airbags and Passengers
If a steering wheel airbag is fitted the following criteria are
used to assess the protection of the head for the driver. These
criteria are always used for the passenger.
Note: HIC36 levels above 1000 have been recorded with
airbags, where there is no hard contact and no established risk of
internal head injury. A hard contact is assumed, if the peak
resultant head acceleration exceeds 80g, or if there is other
evidence of hard contact.
If there is no hard contact a score of 4 points is awarded. If
there is hard contact, the following limits are used:
Higher performance limit
HIC 36
650 (5% risk of injury ≥ AIS3 [1,2]) Resultant Acc. 3 msec
exceedence 72g
Lower performance and capping limit
HIC 36 1000* (20% risk of injury ≥ AIS3 [1,2]) Resultant Acc.
3 msec exceedence 88g (*EEVC limit)
3.1.1.2 Drivers with No Steering Wheel Airbag
If no steering wheel airbag is fitted, and the following
requirements are met in the frontal impact test:
HIC 36
<1000 Resultant Acc. 3 msec exceedence <88g,
then 6.8 kg spherical headform test specified in ECE
Regulation 12 [3] are carried out on the steering wheel. The tester
attempts to choose the most aggressive sites to test and it is
expected that two tests will be required, one aimed at the hub
and spoke junction and one at the rim and spoke junction. The
assessment is then based on the following criteria:
Version 5.1 October 20096
Higher performance limit
Resultant peak Acc. 80g
Resultant Acc. 3 msec exceedence 65g
Lower performance and capping limit
HIC36 1000
Resultant peak Acc. 120g
Resultant Acc. 3 msec exceedence 80g
From the face form tests, a maximum of 2 points are awarded
for performance better than the lower limits. For values worse
than the lower performance limit, no points are awarded.
The results from the worst performing test are used for the
assessment. This means that for cars, not equipped with a
steering wheel airbag, the maximum score obtainable for the
driver’s head is
2 points.
3.1.2Neck
Higher performance limit
Shear 1.9kN @ 0 msec, 1.2kN @ 25 - 35msec, 1.1kN @
45msec
Tension 2.7kN @ 0 msec, 2.3kN @ 35msec, 1.1kN @ 60msec
Extension 42Nm
Lower performance and capping limit
Shear 3.1kN @ 0msec, 1.5kN @ 25 - 35msec, 1.1kN @
45msec*
Tension 3.3kN @ 0msec, 2.9kN @ 35msec, 1.1kN @ 60msec*
Extension 57Nm* (Significant risk of injury [4])
(*EEVC Limits) Note: Neck Shear and Tension are assessed
from cumulative exceedence plots, with the limits being
functions of time. By interpolation, a plot of points against time
is computed.
The minimum point on this plot gives the score. Plots of the
limits and colour rating boundaries are given in Appendix I.
