the axis of rotation (e.g. towards the rear) of the seat cushion support structure.
6.5. The adjustment position of the seat cushion base on which the dummy is to be installed
shall be determined by sequential completion (where applicable to the seat design) of the
steps outlined in Paragraphs 6.6. to 6.13. of this Annex below; with the test vehicle at the
vehicle measuring attitude established in accordance with Paragraph 3. of this Annex
above.
6.6. Use the seat control that primarily moves the seat vertically to adjust the SCRP to the
uppermost vertical location.
6.7. Use the seat control that primarily moves the seat fore/aft to adjust the SCRP to the
rearmost location.
6.8. Determine and record (by measuring the seat cushion reference line angle), the full angular
adjustment range of the seat cushion pitch and using only the control(s) that primarily
adjust(s) the cushion pitch, set the cushion pitch as close as possible to the mid-angle.

7.6.2. Where a Design Seat Back Position is Not Specified by the Manufacturer:
7.6.2.1. Set the seat back to the first detent position rearward of 25° from the vertical.
7.6.2.2. If there is no detent position rearward of 25° from the vertical, set the seat back angle to the
most reclined adjustment position.
7.7. Adjust the seat and back assembly of the 3-D H machine so that the centre plane of the
occupant (C/LO) coincides with the centre plane of the 3-D H machine.
7.8. Set the lower leg segments to the 50 percentile length (417mm) and the thigh bar segment
to the 10 percentile length (408mm).
7.9. Attach the foot and lower leg assemblies to the seat pan assembly, either individually or by
using the T-bar and lower leg assembly. The line through the H-point sight buttons should
be parallel to the ground and perpendicular to the C/LO of the seat.
7.10. Adjust the Feet and Leg Positions of the 3-D H Machine as Follows:
7.10.1. Both feet and leg assemblies are moved forward in such a way that the feet take up natural
positions on the floor, between the operating pedals if necessary. Where possible, the left
foot is located approximately the same distance to the left of the centre plane of the 3-D H
machine as the right foot is to the right. The spirit level verifying the transverse orientation of
the 3-D H machine is brought to the horizontal by readjustment of the seat pan if necessary,
or by adjusting the leg and foot assemblies towards the rear. The line passing through the
H-point sight buttons is maintained perpendicular to the C/LO of the seat.
7.10.2. If the left leg cannot be kept parallel to the right leg and the left foot cannot be supported by
the structure, move the left foot until it is supported. The alignment of the sight buttons is
maintained.
7.11. Apply the lower leg and thigh weights and level the 3-D H machine.
7.12. Tilt the back pan forward against the forward stop and draw the 3-D H machine away from
the seat back using the T-bar. Reposition the 3-D H machine on the seat by one of the
following methods:
7.12.1. If the 3-D H machine tends to slide rearward, use the following procedure. Allow the 3-D H
machine to slide rearward until a forward horizontal restraining load on the T-bar is no
longer required (i.e. until the seat pan contacts the seat back). If necessary, reposition the
lower leg.
7.12.2. If the 3-D H machine does not tend to slide rearward, use the following procedure. Slide the
3-D H machine rearwards by applying a horizontal rearward load to the T-bar until the seat
pan contacts the seat back (see Figure 5-2 of Annex 5).
7.13. Apply a 100N ± 10N load to the back and pan assembly of the 3-D H machine at the
intersection of the hip angle quadrant and the T-bar housing. The direction of load
application is maintained along a line passing by the above intersection to a point just above
the thigh bar housing (see Figure 5-2 of Annex 5). Then carefully return the back pan to the
seat back. Care must be exercised throughout the remainder of the procedure to prevent
the 3-D H machine from sliding forward.

7.21. Where a Design Torso Angle is Not Specified by the Manufacturer:
7.21.1. 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 23° ± 1°.
7.22. Where a design torso angle is not specified by the manufacturer and no seat back angular
adjustment position produces an actual torso angle within the 23° ± 1° range:
7.22.1. 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 as close to 23° as possible.
7.23. Record the Final Actual Torso Angle for Future Reference.
7.24. Measure and record the manikin H-point (X, Y, Z) coordinates in the vehicle reference
coordinate system for future reference.
7.25. Except as provided in Paragraph 8.4.6. of this Annex; the coordinates recorded in
accordance with Paragraph 7.24. above define the manikin H-point location of the seat,
when the seat is adjusted to the final seat cushion and seat back detent test positions for
the installation of the dummy.
7.26. If a rerun of the installation of the 3-D H machine is desired, the seat assembly should
remain unloaded for a minimum period of 30min prior to the rerun. The 3-D H machine
should not be left loaded on the seat assembly longer than the time required to perform the
test.
8. WORLDSID 50 PERCENTILE ADULT MALE INSTALLATION REQUIREMENTS
8.1. Adjustable lumbar supports, other adjustable seat supports and adjustable head restraints
shall be set to the adjustment positions specified in Paragraph 4. of this Annex.
8.2. Passenger compartment adjustments shall be set to the adjustment positions specified in
Paragraph 5. of this Annex.
8.3. The test dummy shall then be installed by completion of the steps outlined in
Paragraph 8.4. below; with the test vehicle at the vehicle measuring attitude established in
accordance with Paragraph 3. of this Annex.
8.4. Dummy Installation Procedure
8.4.1. Place the test dummy in the applicable seat such that the mid-sagittal plane is coincident
with the C/LO and the upper torso is resting against the seat back.
8.4.2. Apply a for/aft and lateral rocking motion to settle the pelvis rearward in the seat.
8.4.3. Where the abdominal rib coupler and/or the outer band of each (i.e. left/right) lower
abdominal rib assembly contacts the pelvis flesh, ensure the contacting surfaces of the
abdominal rib coupler and the outer band of each lower abdominal rib are positioned
in-behind the inner abdominal wall of the pelvis flesh, not on top of the pelvis flesh.

8.4.10.3. Where a design rib angle is not specified by the manufacturer and the final actual torso
angle recorded in accordance with Paragraph 7. of this Annex is not 23º ± 1º; no further
adjustment of the dummy rib angle is required.
8.4.11. Adjust the test dummy neck bracket to level the head at the closest position to 0º (as
measured about the head core tilt sensor y-axis).
8.4.12. Proceed to the final foot and leg positioning by repeating the steps outlined in
Paragraph 8.4.7. of this Annex for a driver seating position or the steps outlined in
Paragraph 8.4.8. of this Annex for a passenger seating position.
8.4.13. Verify that the test dummy H-point and dummy rib angle are still in accordance with
Paragraphs 8.4.9. and 8.4.10. of this Annex respectively. If not, repeat the steps outlined

coordinate system and record the final dummy rib angle and head core tilt sensor angles.
8.4.15. Place both arms at the 48º detent position. In this position, each half arm bone plane of
symmetry forms an angle of 48° ± 1° with the adjacent (i.e. left/right as applicable) shoulder
median plane.
8.5. Dummy Installation Notes and Recommendations
8.5.1. No distance is specified for the test dummy knee spacing. However, priority should be given
to ensure:
8.5.1.1. At least 5mm clearance between the knees/legs and the steering shroud and centre
console;
8.5.1.2. A stable foot and ankle position; and
8.5.1.3. The legs are as parallel as possible to the mid-sagittal plane.
8.6. Safety-belt System
8.6.1. The dummy installed in accordance with Paragraph 8.4. of this Annex shall be restrained as
follows using the safety-belt system provided for the seating position by the manufacturer:
8.6.1.1. Carefully place the safety-belt across the dummy and fasten as normal.
8.6.1.2. Remove slack from the lap section of the webbing until it is resting gently around the pelvis
of the dummy. Only minimal force should be applied to the webbing when removing slack.
The route of the lap-belt should be as natural as possible.
8.6.1.3. Place one finger behind the diagonal section of the webbing at the height of the dummy
sternum. Pull the webbing horizontally forward and away from the chest, and utilizing the
force provided by the retractor mechanism only, allow it to freely retract in the direction of
the upper anchorage. Repeat this step three times.

ANNEX 6
TEST CONDITIONS AND PROCEDURES FOR THE ASSESSMENT
OF POST-CRASH HYDROGEN FUEL SYSTEM INTEGRITY
Determination of compliance with the requirements of Paragraph 5.5.2. of this Regulation.
2. DEFINITIONS
For the purposes of this Annex:
2.1. "Enclosed spaces" indicates the special volumes within the vehicle (or the vehicle outline
across openings) that are external to the hydrogen system (storage system, fuel cell system
and fuel flow management system) and its housings (if any) where hydrogen may accumulate
(and thereby pose a hazard), such as the passenger compartment, luggage compartment and
space under the hood.
2.2. "Luggage compartment" is the space in the vehicle for luggage and/or goods
accommodation, bounded by the roof, hood, floor, side walls, being separated from the
passenger compartment by the front bulkhead or the rear bulkhead.
2.3. "Nominal working pressure (NWP)" is the gauge pressure that characterizes typical
operation of a system. For compressed hydrogen gas containers, NWP is the settled pressure
of compressed gas in a fully fuelled container or storage system at a uniform temperature of
15°C.
3. PREPARATION, INSTRUMENTATION AND TEST CONDITIONS
3.1. Compressed Hydrogen Storage Systems and Downstream Piping
3.1.1. Prior to conducting the crash test, instrumentation is installed in the hydrogen storage system
to perform the required pressure and temperature measurements if the standard vehicle does
not already have instrumentation with the required accuracy.
3.1.2. The hydrogen storage system is then purged, if necessary, following manufacturer directions to
remove impurities from the container before filling the storage system with compressed
hydrogen or helium gas. Since the storage system pressure varies with temperature, the
targeted fill pressure is a function of the temperature. The target pressure shall be determined
from the following equation:
P = NWP × (273 + T )/288
where NWP is the nominal working pressure (MPa), T is the ambient temperature to which the
storage system is expected to settle, and P is the targeted fill pressure after the
temperature settles.
3.1.3. The container is filled to a minimum of 95% of the targeted fill pressure and allowed to settle
(stabilize) prior to conducting the crash test.
3.1.4. The main stop valve and shut-off valves for hydrogen gas, located in the downstream hydrogen
gas piping, are in normal driving condition immediately prior to the impact.

4.1.3. If the calculated value of Δt is less than 60min, Δt is set to 60min.
4.2. The initial mass of hydrogen in the storage system can be calculated as follows:
P ' = P × 288/(273 + T )
ρ ' = –0.0027 × (P ') + 0.75 × P ' + 0.5789
M = ρ ' × V
4.3. Correspondingly, the final mass of hydrogen in the storage system, M , at the end of the time
interval, Δt, can be calculated as follows:
P ' = P × 288/(273 + T )
ρ ' = –0.0027 × (P ') + 0.75 × P ' + 0.5789
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).
4.4. The average hydrogen flow rate over the time interval is therefore:
V = (M - M )/Δt × 22.41/2.016 × (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. POST-CRASH LEAK TEST MEASUREMENT FOR A COMPRESSED HYDROGEN
STORAGE SYSTEM FILLED WITH COMPRESSED HELIUM
5.1. The helium gas pressure, P (MPa), and temperature T (°C), are measured immediately
before the impact and then at a predetermined time interval after the impact.
5.1.1. The time interval, Δt, starts when the vehicle comes to rest after the impact and continues for at
least 60min.
5.1.2. 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:
Δt = V × NWP/1,000 × ((-0.028 × NWP + 5.5) × R – 0.3) – 2.6 × 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 storage system (L),
and Δt is the time interval (min).
5.1.3. If the value of Δt is less than 60min, Δt is set to 60min.

4. ABDOMINAL PERFORMANCE CRITERIA
4.1. The maximum abdominal rib deflection is the maximum deflection of any (upper or lower)
abdominal 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 abdominal rib, and filtered at a CFC of 600Hz.
4.2. The value of the resultant lower spine (T12) acceleration (a ) which is exceeded for 3ms
cumulatively (i.e. across one or more peaks) is calculated from the expression:
Where:
a = a + a + a
a = the longitudinal (x-axis) acceleration of the dummy lower spine recorded versus time and
filtered at a CFC of 180Hz;
a = the lateral (y-axis) acceleration of the dummy lower spine recorded versus time and
filtered at a CFC of 180Hz; and
a = the vertical (z-axis) acceleration of the dummy lower spine recorded versus time and
filtered at a CFC of 180Hz.
5. PELVIS PERFORMANCE CRITERIA
5.1. The peak pubic symphysis force is the maximum force measured by the load cell at the pubic
symphysis of the pelvis and filtered at a CFC of 600Hz.
