ANNEX 3

DYNAMIC POLE SIDE IMPACT TEST PROCEDURE

1.   PURPOSE
Determination of compliance with the requirements of paragraph 5 of this Regulation.
2.   DEFINITIONS
For the purposes of this annex:








2.1.


"Fuel ballast" means water; or Stoddard Solvent; or any other homogeneous liquid with a specific gravity of 1,0 + 0/-0,25 and a dynamic viscosity of 0,9 ±0,05 mPa·s at 25 °C.












2.2.


"Impact reference line" is the line formed on the impact side of the test vehicle by the intersection of the exterior surface of the vehicle and a vertical plane passing through the centre of gravity of the head of the dummy positioned in accordance with Annex 4, in the front-row outboard designated seating position on the impact side of the vehicle. The vertical plane forms an angle of 75° with the vehicle longitudinal centreline. The angle is measured as indicated in Annex 7, Figure 7-1 (or Figure 7-2) for left (or right) side impact.












2.3.


"Impact velocity vector" means the geometric quantity which describes both the speed and direction of travel of the vehicle at the moment of impact with the pole. The impact velocity vector points in the direction of travel of the vehicle. The origin of the impact velocity vector is the centre of gravity of the vehicle and its magnitude (length) describes the impact speed of the vehicle.












2.4.


"Laden attitude" means the pitch and roll angle of the test vehicle when positioned on a level surface with all tyres fitted and inflated as recommended by the vehicle manufacturer and loaded to the laden mass. The test vehicle is loaded by centrally positioning 136 kg or the rated cargo and luggage mass (whichever is less) in the cargo/luggage carrying area over the longitudinal centreline of the vehicle. The mass of the necessary anthropomorphic test device is placed on the front-row outboard designated seating position on the impact side of the vehicle. The front-row seat on the impact side of the vehicle is positioned in accordance with Annex 4.












2.5.


"Laden mass" means unladen vehicle mass, plus 136 kg or the rated cargo and luggage mass (whichever is less), plus the mass of the necessary anthropomorphic test device.

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.












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.

6.13.


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. (3)





7.   PROCEDURE FOR MANIKIN H-POINT AND ACTUAL TORSO ANGLE DETERMINATION








7.1.

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 50th percentile adult male occupant, in the manner specified by the manufacturer.












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 50th percentile length (417 mm) and the thigh bar segment to the 10th percentile length (408 mm).












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 100 N ± 10 N 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.












7.14.


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 degrees arc (5 degrees 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 25 N, 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.












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 30 minutes 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.

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 (± 10 mm) 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 (± 10 mm) 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 5 mm. 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 floor-pan. In case of tibia contact, slide the foot rearward (towards the seat) until a 5 mm 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 5 mm 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 5 mm 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 ± 5 mm. 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 -2° (i.e. 2° downwards) ± 1° (about the sensor y-axis).












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 23° ± 1°, 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 0° (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 from paragraph 8.4.9 of this annex onwards.












8.4.14.


Measure and record the final test dummy H-point position in the vehicle reference coordinate system and record the final dummy rib angle and head core tilt sensor angles.












8.4.15.


Place both arms at the 48° 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 5 mm 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.






(1)  Details of the H-point locator assembly (H-point tool) including dimensions are specified in Addendum 2 of Mutual Resolution No 1.

(2)  The steering wheel is not expected to influence the loading of the dummy – the highest position is specified in order to provide maximum clearance of the dummy legs and thorax.

(3)  For some seats, the adjustments specified in paragraphs 6.9 to 6.12 may automatically alter the seat cushion pitch from the mid-angle established in accordance with paragraph 6.8. This is acceptable.

(4)  Seat centreline markings may be used to identify the C/LO and to facilitate placement of the dummy.

(5)  To ensure that a repeatable and stable pelvis position will be achieved, it is recommended following the completion of this step, to verify that the pelvis is in contact with the seat cushion over the whole pelvis length.





ANNEX 5

DESCRIPTION OF THE THREE-DIMENSIONAL H-POINT MACHINE
             (1)
(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 76 kg male. All joints of the 3-D H machine should be checked for free movement without encountering noticeable friction.

ANNEX 6

TEST CONDITIONS AND PROCEDURES FOR THE ASSESSMENT OF POST-CRASH HYDROGEN FUEL SYSTEM INTEGRITY

1.   PURPOSE
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:
Ptarget = NWP × (273 + To)/288
where NWP is the nominal working pressure (MPa), To is the ambient temperature to which the storage system is expected to settle, and Ptarget is the targeted fill pressure after the temperature settles.












3.1.3.


The container is filled to a minimum of 95 per cent 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.












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 per cent at the targeted criteria of 4 per cent hydrogen or 3 per cent helium by volume in air, and a full scale measurement capability of at least 25 per cent above the target criteria. The sensor shall be capable of a 90 per cent response to a full scale change in concentration within 10 seconds.












3.2.3.


Prior to the crash impact, the sensors are located in the passenger and luggage compartments of the vehicle as follows:






(a)


At a distance within 250 mm of the headliner above the driver’s seat or near the top centre of the passenger compartment;










(b)


At a distance within 250 mm of the floor in front of the rear (or rear most) seat in the passenger compartment; and










(c)


At a distance within 100 mm 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, P0 (MPa), and temperature, T0 (°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 60 minutes.












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:
Δt = VCHSS × NWP/1000 × ((-0,027 x NWP +4) × Rs
               0,21) –1,7 x Rs

where Rs = Ps/NWP, Ps is the pressure range of the pressure sensor (MPa), NWP is the Nominal Working Pressure (MPa), VCHSS is the volume of the compressed hydrogen storage system (l), and Δt is the time interval (min).












4.1.3.


If the calculated value of Δt is less than 60 minutes, Δt is set to 60 minutes.












4.2.


The initial mass of hydrogen in the storage system can be calculated as follows:
Po’ = Po × 288/(273 + T0)
ρο’ = –0,0027 × (P0’)2 +0,75 × P0’ +0,5789
Mo = ρο’ × VCHSS













4.3.


Correspondingly, the final mass of hydrogen in the storage system, Mf, at the end of the time interval, Δt, can be calculated as follows:
Pf’ = Pf x 288/(273 + Tf)
ρf’ = –0,0027 × (Pf’)2 +0,75 x Pf’ +0,5789
Mf = ρf’ × VCHSS

where Pf is the measured final pressure (MPa) at the end of the time interval, and Tf is the measured final temperature (°C).












4.4.


The average hydrogen flow rate over the time interval is therefore:
VH2 = (Mf-Mo)/Δt × 22,41/2,016 × (Ptarget/Po)
where VH2 is the average volumetric flow rate (NL/min) over the time interval and the term (Ptarget/Po) is used to compensate for differences between the measured initial pressure (Po) and the targeted fill pressure (Ptarget).




5.   POST-CRASH LEAK TEST MEASUREMENT FOR A COMPRESSED HYDROGEN STORAGE SYSTEM FILLED WITH COMPRESSED HELIUM








5.1.


The helium gas pressure, P0 (MPa), and temperature T0 (°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 60 minutes.












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 70 MPa; in that case, Δt can be calculated from the following equation:
Δt = VCHSS × NWP/1000 × ((-0,028 × NWP +5,5) × Rs
               –0,3) – 2,6 × Rs

where Rs = Ps/NWP, Ps is the pressure range of the pressure sensor (MPa), NWP is the Nominal Working Pressure (MPa), VCHSS is the volume of the compressed hydrogen storage system (l), and Δt is the time interval (min).












5.1.3.


If the value of Δt is less than 60 minutes, Δt is set to 60 minutes.












5.2.


The initial mass of helium in the storage system is calculated as follows:
Po’ = Po × 288/(273 + T0)
ρο’ = –0,0043 × (P0’)2 +1,53 x P0’ +1,49
Mo = ρο’ × VCHSS













5.3.


The final mass of helium in the storage system at the end of the time interval, Δt, is calculated as follows:
Pf’ = Pf × 288/(273 + Tf)
ρf’ = –0,0043 × (Pf’)2 +1,53 × Pf’ +1,49
Mf = ρf’ × VCHSS

where Pf is the measured final pressure (MPa) at the end of the time interval, and Tf is the measured final temperature (°C).












5.4.


The average helium flow rate over the time interval is therefore:
VHe = (Mf-Mo)/Δt × 22,41/4,003 × (Ptarget/Po)
where VHe is the average volumetric flow rate (NL/min) over the time interval and the term (Ptarget/Po) is used to compensate for differences between the measured initial pressure (Po) and the targeted fill pressure (Ptarget).












5.5.


Conversion of the average volumetric flow of helium to the average hydrogen flow is done with the following expression:
VH2 = VHe/0,75
where VH2 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 5 seconds and continue for a period of 60 minutes after the test. A first-order lag (time constant) up to a maximum of 5 seconds may be applied to the measurements to provide "smoothing" and filter the effects of spurious data points.
