for a 50 percentile adult male occupant or the uppermost position if no design position is
available.
5. PASSENGER COMPARTMENT ADJUSTMENTS
5.1. Where applicable, the adjustment specified in Paragraph 5.1.1. of this Annex; and in the
case where the dummy is to be installed on the driver's side, the adjustments specified in
Paragraphs 5.1.2. and 5.1.3. of this Annex; shall be performed on the vehicle.

6.9. Use the seat control that primarily moves the seat vertically to adjust the SCRP to the lowest
vertical location. Verify that the seat cushion is still at the rearmost seat track location.
Record the longitudinal (X-axis) position of the SCRP in the vehicle reference coordinate
system.
6.10. Use the seat control that primarily moves the seat fore/aft to adjust the SCRP to the forward
most location. Record the longitudinal (X-axis) position of the SCRP in the vehicle reference
coordinate system.
6.11. Determine the vehicle X-axis position of a vertical transverse plane 20mm rearward of a
point midway between the longitudinal (X-axis) positions recorded in accordance with
Paragraphs 6.9. and 6.10. above (i.e. 20mm rearward of the mid-track position).
6.12. Use the seat control that primarily moves the seat fore/aft to adjust the SCRP to the
longitudinal (X-axis) position determined in accordance with Paragraph 6.11. (-0/+2mm), or,
if this is not possible, the first available fore/aft adjustment position rearward of the position
determined in accordance with Paragraph 6.11.
6.13. Record the longitudinal (X-axis) position of the SCRP in the vehicle reference coordinate
system and measure the seat cushion reference line angle for future reference. Except as
provided in Paragraph 8.4.6. of this Annex; this adjustment position shall be used as the
final seat cushion adjustment position for the installation of the dummy.
7. PROCEDURE FOR MANIKIN H-POINT AND ACTUAL TORSO ANGLE DETERMINATION
7.1. The test vehicle shall be preconditioned at a temperature of 20°C ± 10°C to ensure that the
seat material reaches stabilised room temperature for the installation of the 3-D H machine.
7.2. Adjustable lumbar supports and other adjustable seat supports shall be set to the
adjustment positions specified in Paragraph 4.1.1. and 4.1.2. of this Annex.
7.3. The manikin H-point coordinates and final actual torso angle shall be determined for the
seat in which the dummy is to be installed, by sequential completion of the steps outlined in
Paragraphs 7.4. to 7.24. of this Annex below; with the test vehicle at the vehicle measuring
attitude established in accordance with Paragraph 3. of this Annex above.
7.4. Cover the area of the seating position to be contacted by the 3-D H machine with a muslin
cotton sheet of sufficient size and place the seat and back assembly of the 3-D H machine
in the seat.
7.5. Set the seat cushion position to the adjustment position recorded in accordance with
Paragraph 6.13. of this Annex.
7.6. Using only the control(s) which primarily adjusts the angle of the seat back, independently of
the seat cushion pitch; adjust the seat back position according to one of the following
methods:
7.6.1. Place adjustable seat backs in the manufacturer's nominal design driving or riding position
for a 50 percentile adult male occupant, in the manner specified by the manufacturer.

7.14. Install the right and left buttock weights and then, alternately, the eight torso weights.
Maintain the 3-D H machine level.
7.15. Tilt the back pan forward to release the tension on the seat back. Rock the 3-D H machine
from side to side through 10° arc (5° to each side of the vertical centre plane) for three
complete cycles to release any accumulated friction between the 3-D H machine and the
seat.
7.15.1. During the rocking action, the T-bar of the 3-D H machine may tend to diverge from the
specified horizontal and vertical alignment. The T-bar must therefore be restrained by
applying an appropriate lateral load during the rocking motions. Care is exercised in holding
the T-bar and rocking the 3-D H machine to ensure that no inadvertent exterior loads are
applied in a vertical or fore and aft directions.
7.15.2. The feet of the 3-D H machine are not to be restrained or held during this step. If the feet
change position, they should be allowed to remain in that attitude for the moment.
7.16. Carefully return the back pan to the seat back and check the two spirit levels for zero
position. If any movement of the feet has occurred during the rocking operation of the 3-D H
machine, they must be repositioned as follows:
7.16.1. Alternately, lift each foot off the floor the minimum necessary amount until no additional foot
movement is obtained. During this lifting, the feet are to be free to rotate; and no forward or
lateral loads are to be applied. When each foot is placed back in the down position, the heel
is to be in contact with the structure designed for this.
7.17. Check the lateral spirit level for zero position; if necessary, apply a lateral load to the top of
the back pan sufficient to level the 3-D H machine's seat pan on the seat.
7.18. Holding the T-bar to prevent the 3-D H machine from sliding forward on the seat cushion,
proceed as follows:
7.18.1. Return the back pan to the seat back; and
7.18.2. Alternately apply and release a horizontal rearward load, not to exceed 25N, to the back
angle bar at a height approximately at the centre of the torso weights until the hip angle
quadrant indicates that a stable position has been reached after load release. Care is
exercised to ensure that no exterior downward or lateral loads are applied to the 3-D H
machine. If another level adjustment of the 3-D H machine is necessary, rotate the back pan
forward, re-level, and repeat all procedures from Paragraph 6.15. of this Annex onwards.
7.19. Use the 3-D H machine back angle quadrant, with the head room probe in its fully rearward
position, to measure the actual torso angle.
7.20. If necessary, use only the control(s) which primarily adjusts the angle of the seat back
independently of the seat cushion pitch; to adjust the actual torso angle to the design torso
angle ±1° specified by the manufacturer.

8.4.4. Move the seat cushion and seat back together with the test dummy to the final adjustment
position used to determine the manikin H-point and actual torso angle in Paragraph 7. of this
Annex.
8.4.5. Verify that the dummy H-point is reasonably close (±10mm) to the WS50M H-point defined
in Paragraph 2.25. of this Annex. If not, repeat the procedures outlined in Paragraphs 8.4.2.
to 8.4.3. of this Annex. If it is still not possible to verify the dummy
H-point is reasonably close (±10mm) to the WS50M H-point, record the offset and proceed
to the next step.
8.4.6. If it is not possible to reach the seat test position due to knee contact, shift the targeted test
seat position rearwards in stepwise increments to the closest position where the knee
clearance is at least 5mm. Record the adjustment of the SCRP position and modify the
manikin H-point and WS50M H-point coordinates accordingly.
8.4.7. For a Driver Seating Position:
8.4.7.1. Extend the right leg without displacing the thigh from the seat cushion and allow the sole of
the foot to settle on the accelerator pedal. The heel of the shoe should be in contact with the
floor-pan.
8.4.7.2. Extend the left leg without displacing the thigh from the seat cushion and allow the sole of
the foot to settle on the footrest. The heel of the shoe should be in contact with the floorpan.
In case of tibia contact, slide the foot rearward (towards the seat) until a 5mm
clearance is obtained.
8.4.8. For a Passenger Seating Position:
8.4.8.1. Extend each leg without displacing the thigh from the seat cushion.
8.4.8.2. Allow the sole of the right foot to settle on the floor-pan in-line (i.e. in the same vertical
plane) with the thigh. The heel of the shoe should be in contact with the floor-pan. If the
contour of the floor-pan does not permit the foot to rest on a planar surface, move the foot in
5mm increments until the foot rests on a planar surface.
8.4.8.3. Allow the sole of the left foot to settle on the floor-pan in-line (i.e. in the same vertical plane)
with the thigh and in the same for/aft location (alignment) as the right foot. The heel of the
shoe should be in contact with the floor-pan. If the contour of the floor-pan does not permit
the foot to rest on a planar surface, move the foot in 5mm increments until the foot rests on
a planar surface.
8.4.9. Position the dummy H-point to match the WS50M H-point coordinates (defined by
Paragraph 2.25. of this Annex) within ±5mm. Priority should be given to the X-axis
coordinate.
8.4.10. Adjust the dummy rib angle as follows:
8.4.10.1. Adjust the dummy until the thorax tilt sensor angle reading (about the sensor y-axis) is
within ±1° of the design rib angle specified by the manufacturer.
8.4.10.2. Where a design rib angle is not specified by the manufacturer and the final actual torso
angle determined in accordance with Paragraph 7. of this Annex is 23° ± 1°; adjust the
dummy until the thorax tilt sensor reads -2º (i.e. 2º downwards) ± 1º (about the sensor
y-axis).

ANNEX 5
DESCRIPTION OF THE THREE-DIMENSIONAL H-POINT MACHINE (3-D H MACHINE)
1. BACK AND SEAT PANS
The back and seat pans are constructed of reinforced plastic and metal; they simulate the human
torso and thigh and are mechanically hinged at the H-point. A quadrant is fastened to the probe
hinged at the H-point to measure the actual torso angle. An adjustable thigh bar, attached to the
seat pan, establishes the thigh centreline and serves as a baseline for the hip angle quadrant.
2. BODY AND LEG ELEMENTS
Lower leg segments are connected to the seat pan assembly at the T-bar joining the knees, which
is a lateral extension of the adjustable thigh bar. Quadrants are incorporated in the lower leg
segments to measure knee angles. Shoe and foot assemblies are calibrated to measure the foot
angle. Two spirit levels orient the device in space. Body element weights are placed at the
corresponding centres of gravity to provide seat penetration equivalent to a 76kg male. All joints of
the 3-D H machine should be checked for free movement without encountering noticeable friction.

3.2. Enclosed Spaces
3.2.1. Sensors are selected to measure either the build-up of the hydrogen or helium gas or the
reduction in oxygen (due to displacement of air by leaking hydrogen/helium).
3.2.2. Sensors are calibrated to traceable references to ensure an accuracy of ±5% at the targeted
criteria of 4% hydrogen or 3% helium by volume in air, and a full scale measurement capability
of at least 25% above the target criteria. The sensor shall be capable of a 90% response to a
full scale change in concentration within 10s.
3.2.3. Prior to the crash impact, the sensors are located in the passenger and luggage compartments
of the vehicle as follows:
(a)
(b)
(c)
At a distance within 250mm of the headliner above the driver's seat or near the top
centre of the passenger compartment;
At a distance within 250mm of the floor in front of the rear (or rear most) seat in the
passenger compartment; and
At a distance within 100mm of the top of luggage compartments within the vehicle that
are not directly affected by the particular crash impact to be conducted.
3.2.4. The sensors are securely mounted on the vehicle structure or seats and protected for the
planned crash test from debris, air bag exhaust gas and projectiles. The measurements
following the crash are recorded by instruments located within the vehicle or by remote
transmission.
3.2.5. The test may be conducted either outdoors in an area protected from the wind and possible
solar effects or indoors in a space that is large enough or ventilated to prevent the build-up of
hydrogen to more than 10 per cent of the targeted criteria in the passenger and luggage
compartments.
4. POST-CRASH LEAK TEST MEASUREMENT FOR A COMPRESSED HYDROGEN
STORAGE SYSTEM FILLED WITH COMPRESSED HYDROGEN
4.1. The hydrogen gas pressure, P (MPa), and temperature, T (°C), are measured immediately
before the impact and then at a time interval, Δt (min), after the impact.
4.1.1. The time interval, Δt, starts when the vehicle comes to rest after the impact and continues for at
least 60min.
4.1.2. The time interval, Δt, shall be increased if necessary in order to accommodate measurement
accuracy for a storage system with a large volume operating up to 70MPa; in that case, Δt can
be calculated from the following equation:
∆t = V × NWP/1,000 x ((-0.027 × NWP + 4) × R – 0.21) -1.7 × R
where R = P / NWP, P is the pressure range of the pressure sensor (MPa), NWP is the
Nominal Working Pressure (MPa), V is the volume of the compressed hydrogen storage
system (L), and Δt is the time interval (min).

5.2. The initial mass of helium in the storage system is calculated as follows:
P ' = P × 288/(273 + T )
ρ ' = -0.0043 × (P ') + 1.53 × P ' + 1.49
M = ρ ' × V
5.3. The final mass of helium in the storage system at the end of the time interval, Δt, is calculated
as follows:
P ' = P × 288/(273 + T )
ρ ' = –0.0043 × (P ') + 1.53 × P ' + 1.49
M = ρ ' × V
where P is the measured final pressure (MPa) at the end of the time interval, and T is the
measured final temperature (°C).
5.4. The average helium flow rate over the time interval is therefore:
V = (M - M )/Δt × 22.41/4.003 × (P /P )
where V is the average volumetric flow rate (NL/min) over the time interval and the term
(P /P ) is used to compensate for differences between the measured initial pressure (P )
and the targeted fill pressure (P ).
5.5. Conversion of the average volumetric flow of helium to the average hydrogen flow is done with
the following expression:
V = V /0.75
where V is the corresponding average volumetric flow of hydrogen.
6. POST-CRASH CONCENTRATION MEASUREMENT FOR ENCLOSED SPACES
6.1. Post-crash data collection in enclosed spaces commences when the vehicle comes to a rest.
Data from the sensors installed in accordance with Paragraph 3.2. of this Annex are collected
at least every 5s and continue for a period of 60min after the test. A first-order lag (time
constant) up to a maximum of 5s may be applied to the measurements to provide "smoothing"
and filter the effects of spurious data points.

1. HEAD INJURY CRITERION (HIC)
1.1. The Head Injury Criterion (HIC) 36 is the maximum value calculated from the expression:
HIC36

Where:
a = the resultant translational acceleration at the centre of gravity of the dummy head
recorded versus time in units of gravity, g (1g = 9.81m/s ); and
t and t are any two points in time during the impact which are separated by not more than a
36ms time interval and where t is less than t .
1.2. The resultant acceleration at the centre of gravity of the dummy head is calculated from the
expression:
Where:
a = a + a + a
a = the longitudinal (x-axis) acceleration at the centre of gravity of the dummy head recorded
versus time and filtered at a channel frequency class (CFC) of 1,000Hz;
a = the lateral (y-axis) acceleration at the centre of gravity of the dummy head recorded versus
time and filtered at a CFC of 1,000Hz; and
a = the vertical (z-axis) acceleration at the centre of gravity of the dummy head recorded
versus time and filtered at a CFC of 1,000Hz.
2. SHOULDER PERFORMANCE CRITERIA
2.1. The peak lateral (y-axis) shoulder force is the maximum lateral force measured by the load cell
mounted between the shoulder clevis assembly and the shoulder rib doubler and filtered at a
CFC of 600Hz.
3. THORAX PERFORMANCE CRITERIA
3.1. The maximum thorax rib deflection is the maximum deflection of any (upper, middle or lower)
thorax rib, as determined from the voltage output measurements recorded by the deflection
sensor mounted between the rib accelerometer mounting bracket and central spine box
mounting bracket inside each struck-side thorax rib, and filtered at a CFC of 600Hz.
