APPENDIX 2
TEST PROCEDURE FOR THE ANCHORAGES OF A
VEHICLE IN APPLICATION OF PARAGRAPH 6.1.1.
1. TEST APPARATUS
1.1. A rigid structure sufficiently representative of the seat intended for use on the vehicle is fixed
by the means of fixation (bolts, screws, etc.) provided by the manufacturer to the parts of the
structure submitted to the tests.
1.2. If several seat types differing from one another in respect of the distance between the front
and back ends of their feet can be mounted on the same anchorage, the test shall be carried
out with the shortest footing. This footing shall be described on the type approval certificate.
2. TEST PROCEDURE
2.1. A force F shall be applied.
2.1.1. At a height of 750mm above the reference plane and on the vertical line containing the
geometrical centre of the surface bounded by the polygon having the different anchorage
points as apexes or, if applicable, the extreme anchorages of the seat, by the rigid structure
as defined in Paragraph 1.1. above;
2.1.2. In the horizontal direction and directed to the front of the vehicle;
2.1.3. In a delay as short as possible and for a duration of at least 0.2s.
2.2. The force F shall be determined either
2.2.1. By the following formula: F = (5,000 ± 50) × i where:
F is given in N and i represents the number of seating positions of the seat for which the
anchorages to be tested are to be approved; or, if requested by the manufacturer,
2.2.2. In accordance with the representative loads measured during dynamic tests as described in
Appendix 1 to this Regulation.

APPENDIX 4
DETERMINATION OF ACCEPTABILITY CRITERIA
1. FRONTAL IMPACT (FORWARD-FACING SEAT)
1.1. Head Acceptability Criterion (HIC)
1.1.1. This injury criterion (HIC) is calculated on the basis of the resultant triaxial acceleration
measured according to Appendix 3, Paragraph 2.2.1. by the following expression:

1
HIC =
⎢ t − t ∫

( t − t ) ⎢ γ dt
in which t and t are any values of time during the test, HIC being maximum value for and
interval t , t . The values of t and t are expressed in seconds.
1.2. Thorax Acceptability Criterion (ThAC)
1.2.1. This criterion is determined by the absolute value of resultant acceleration, expressed in g
and measured according to Appendix 3, Paragraph 2.2.2, and by the acceleration period,
expressed in ms.
1.3. Femur Acceptability Criterion (FAC)
This criterion is determined by the compression load expressed in kN, transmitted axially on
each femur of the manikin and measured according to Appendix 3, Paragraph 2.2.3., and by
the duration of the compression load, expressed in ms.
2. SIDE IMPACT (SIDE-FACING SEAT)
2.1. Head Acceptability Criterion (HIC) see above Paragraph 1.1.
2.2. Thorax Acceptability Criterion
2.2.1. Chest deflection: the peak chest deflection is the maximum value of deflection on any rib as
determined by the thorax displacement transducers.
