| 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. |
| --- | --- |

7.15.1.

| 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.

| 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. |
| --- | --- |

7.16.1.

| 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. |
| --- | --- |

7.17.

| 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.

| 7.18.1. | Return the back pan to the seat back; and |
| --- | --- |

7.18.1.

| 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. |
| --- | --- |

7.18.2.

| 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. |
| --- | --- |

7.19.

| 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.

| 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.

| 7.24. | Measure and record the manikin H-point (X, Y, Z) coordinates in the vehicle reference coordinate system for future reference. |

7.24.

| 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. |
| --- | --- |

7.25.

| 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. |

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. |
| --- | --- |

2.1.

| 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. |
| --- | --- |

2.2.

| 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. |
| --- | --- |

2.3.

3.   PREPARATION, INSTRUMENTATION AND TEST CONDITIONS

| 3.1. | Compressed hydrogen storage systems and downstream piping |
| --- | --- |

3.1.

| 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. |
| --- | --- |

3.1.1.

| 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. |
| --- | --- |

3.1.2.

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. |
| --- | --- |

3.1.3.

| 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. |
| --- | --- |

3.1.4.

| 3.2. | Enclosed spaces |
| --- | --- |

3.2.

| 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). |
| --- | --- |

3.2.1.

| 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. |
| --- | --- |

3.2.2.

| 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; |
| --- | --- | --- |

3.2.3.

(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 |
| --- | --- |

(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. |
| --- | --- |

(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. |
| --- | --- |

3.2.4.

| 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. |
| --- | --- |

3.2.5.

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.

| 4.1.1. | The time interval, Δt, starts when the vehicle comes to rest after the impact and continues for at least 60 minutes. |
| --- | --- |

4.1.1.

| 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). |
| --- | --- |

4.1.2.

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. |
| --- | --- |

4.1.3.

| 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 |
| --- | --- |

4.2.

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). |
| --- | --- |

4.3.

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). |
| --- | --- |

4.4.

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.

| 5.1.1. | The time interval, Δt, starts when the vehicle comes to rest after the impact and continues for at least 60 minutes. |
| --- | --- |

5.1.1.

| 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). |
| --- | --- |

5.1.2.

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. |
| --- | --- |

5.1.3.

| 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 |
| --- | --- |

5.2.

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). |
| --- | --- |

5.3.

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). |
| --- | --- |

5.4.

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. |
| --- | --- |

5.5.

VH2 = VHe/0,75

where VH2 is the corresponding average volumetric flow of hydrogen.

| 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. |
