5.3.7.1.3.   Physical protection

For protection against direct contact with high voltage live parts, the protection degree IPXXB shall be provided.

In addition, for protection against electrical shock which could arise from indirect contact, the resistance between all exposed conductive parts and the electrical chassis shall be lower than 0,1 ohm when there is current flow of at least 0,2 ampere.

This requirement is satisfied if the galvanic connection has been made by welding.

5.3.7.1.4.   Isolation resistance

The criteria specified in the paragraphs 5.3.7.1.4.1 and 5.3.7.1.4.2 below shall be met.

The measurement shall be conducted in accordance with paragraph 5 of Annex 9.

5.3.7.1.4.1.   Electrical power train consisting of separate DC- or AC-buses.

If the AC high voltage buses and the DC high voltage buses are galvanically connected isolation resistance between the high voltage bus and the electrical chassis (Ri, as defined in paragraph 5 of Annex 9) shall have a minimum value of 500 Ω/V of the working voltage.

i

However, if the protection degree IPXXB is satisfied for all AC high voltage buses or the AC voltage is equal or less than 30 V after the vehicle impact, the isolation resistance between the high voltage bus and the electrical chassis (Ri, as defined in paragraph 5 of Annex 9) shall have a minimum value of 100 Ω/V of the working voltage.

i

5.3.7.2.   Electrolyte spillage

In the period from the impact until 30 minutes after no electrolyte from the REESS shall spill into the passenger compartment and no more than 7 per cent of electrolyte shall spill from the REESS except open type traction batteries outside the passenger compartment. For open type traction batteries no more than 7 per cent with a maximum of 5,0 litres shall spill outside the passenger compartment.

The manufacturer shall demonstrate compliance in accordance with paragraph 6 of Annex 9.

5.3.7.3.   REESS retention

6.   MODIFICATION OF THE VEHICLE TYPE

6.1.   Any modification affecting the structure, the number and type of seats, the interior trim or fittings, or the position of the vehicle controls or of mechanical parts which might affect the energy-absorption capacity of the side of the vehicle, shall be brought to the notice of the Type Approval Authority granting approval. The Type Approval Authority may then either:

6.1.1.   Consider that the modifications made are unlikely to have an appreciable adverse effect and that in any case the vehicle still complies with the requirements; or

6.1.2.   Require a further test report from the Technical Service responsible for conducting the tests;

6.1.2.1.   Any modification of the vehicle affecting the general form of the structure of the vehicle or any variation in the reference mass greater than 8 per cent which in the judgement of the authority would have a marked influence on the results of the test shall require a repetition of the test as described in Annex 4.

6.1.2.2.   If the Technical Service, after consultation with the vehicle manufacturer, considers that modifications to a vehicle type are insufficient to warrant a complete retest then a partial test may be used. This would be the case if the reference mass is not more than 8 per cent different from the original vehicle or the number of front seats is unchanged. Variations of seat type or interior fittings need not automatically entail a full retest. An example of the approach to this problem is given in Annex 8.

6.2.   Confirmation or refusal of approval, specifying the alteration, shall be communicated by the procedure specified in paragraph 4.4 above to the Parties to the Agreement which apply this Regulation.

6.3.   The Type Approval Authority issuing an extension of approval shall assign a series number to each communication form drawn up for such an extension.

7.   CONFORMITY OF PRODUCTION

7.3.   The Type Approval Authority which has granted type approval may at any time verify the conformity control methods applied in each production facility. The normal frequency of these verifications shall be once every 2 years.

8.   PENALTIES FOR NON-CONFORMITY OF PRODUCTION

8.1.   The approval granted in respect of a vehicle type, pursuant to this Regulation, may be withdrawn if the requirement laid down in paragraph 7.1 above is not complied with, or if the vehicle or vehicles selected have failed to pass the checks prescribed in paragraph 7.2 above.

8.2.   If a Contracting Party to the Agreement applying this Regulation withdraws an approval it has previously granted, it shall forthwith so notify the other Contracting Parties applying this Regulation by means of a communication form conforming to the model in Annex 1 to this Regulation.

9.   PRODUCTION DEFINITIVELY DISCONTINUED

If the holder of the approval completely ceases to manufacture a type of vehicle approved in accordance with this Regulation, he shall so inform the Type Approval Authority which granted the approval. Upon receiving the relevant communication that Authority shall inform thereof the other Parties to the 1958 Agreement applying this Regulation by means of a communication form conforming to the model in Annex 1 to this Regulation.

When head contact takes place, this performance criterion is calculated for the total duration between the initial contact and the last instant of the final contact.

HPC is the maximum value of the expression:

Formula

Where a is the resultant acceleration at the centre of gravity of the head in metres per second divided by 9,81 recorded versus time and filtered at channel frequency class 1 000 Hz; t1 and t2 are any two times between the initial contact and the last instant of the final contact.

2.   THORAX PERFORMANCE CRITERIA

2.1.   Chest deflection: the peak chest deflection is the maximum value of deflection on any rib as determined by the thorax displacement transducers, filtered at channel frequency class 180 Hz.

2.2.   Viscous criterion: the peak viscous response is the maximum value of VC on any rib which is calculated from the instantaneous product of the relative thorax compression related to the half thorax and the velocity of compression derived by differentiation of the compression, filtered at channel frequency class 180 Hz. For the purposes of this calculation the standard width of the half thorax rib cage is 140 mm.

Formula

Where D (metres) = rib deflection

The calculation algorithm to be used is set out in Annex 4, Appendix 2.

3.   ABDOMEN PROTECTION CRITERION

The peak abdominal force is the maximum value of the sum of the three forces measured by transducers mounted 39 mm below the surface on the crash side, CFC 600 Hz.

4.   PELVIS PERFORMANCE CRITERION

The pubic symphisis peak force (PSPF) is the maximum force measured by a load cell at the pubic symphysis of the pelvis, filtered at channel frequency class 600 Hz.

Appendix 2

THE PROCEDURE FOR CALCULATING THE VISCOUS CRITERION FOR EUROSID 1

The Viscous Criterion, VC, is calculated as the instantaneous product of the compression and the rate of deflection of the rib. Both are derived from the measurement of rib deflection. The rib deflection response is filtered once at Channel Frequency Class 180. The compression at time (t) is calculated as the deflection from this filtered signal expressed as the proportion of the half width of the Eurosid 1 chest, measured at the metal ribs (0,14 metres):

Formula

The rib deflection velocity at time (t) is calculated from the filtered deflection as:

Image 4

where D(t) is the deflection at time (t) in metres and ∂t is the time interval in seconds between the measurements of deflection. The maximum value of ∂t shall be 1,25 × 10– 4 seconds.

This calculation procedure is shown diagrammatically below:

4.1.1.   Ensure the existence of effective procedures so that the quality of the products can be inspected;

4.1.2.   Have access to the testing equipment needed to inspect the conformity of each product;

4.1.3.   Ensure that the test results are recorded and that the documents remain available for a time period of 10 years after the tests;

4.1.4.   Demonstrate that the samples tested are a reliable measure of the performance of the batch (examples of sampling methods according to batch production are given below).

4.1.5.   Analyse results of tests in order to verify and ensure the stability of the barrier characteristics, making allowance for variations of an industrial production, such as temperature, raw materials quality, time of immersion in chemical, chemical concentration, neutralisation, etc. and the control of the processed material in order to remove any residue from the processing.

4.1.6.   Ensure that any set of samples or test pieces giving evidence of non-conformity gives rise to a further sampling and test. All the necessary steps must be taken to restore conformity of the corresponding production.

4.2.   The manufacturer's level of certification must be at least ISO 9002 standard.

4.3.   Minimum conditions for the control of production: the holder of an agreement will ensure the control of conformity following the methods hereunder described.

4.4.   Examples of sampling according to batch

4.4.1.   If several examples of one block type are constructed from one original block of aluminium honeycomb and are all treated in the same treatment bath (parallel production), one of these examples could be chosen as the sample, provided care is taken to ensure that the treatment is evenly applied to all blocks. If not, it may be necessary to select more than one sample.

4.4.2.   If a limited number of similar blocks (say 3 to 20) are treated in the same bath (serial production), then the first and last block treated in a batch, all of which are constructed from the same original block of aluminium honeycomb, should be taken as representative samples. If the first sample complies with the requirements but the last does not, it may be necessary to take further samples from earlier in the production until a sample that does comply is found. Only the blocks between these samples should be considered to be approved.

4.4.3.   Once experience is gained with the consistency of production control, it may be possible to combine both sampling approaches, so that more than one groups of parallel production can be considered to be a batch provided samples from the first and last production groups comply.

5.   STATIC TESTS

5.1.   One or more samples (according to the batch method) taken from each batch of processed honeycomb core shall be tested, according to the following test procedure:

5.2.   The sample size of the aluminium honeycomb for static tests shall be the size of a normal block of the impactor, that is to say 250 mm × 500 mm × 440 mm for top row and 250 mm × 500 mm × 500 mm for the bottom row.

5.3.   The samples should be compressed between two parallel loading plates which are at least 20 mm larger than the block cross section.

5.4.   The compression speed shall be 100 millimetres per minute, with a tolerance of 5 per cent.

5.5.   The data acquisition for static compression shall be sampled at a minimum of 5 Hz.

5.6.   The static test shall be continued until the block compression is at least 300 mm for blocks 4 to 6 and 350 mm for blocks 1 to 3.

6.1.2.2.   The front face shall be vertical, perpendicular to the axis of the run-up-tack and equipped with six load cell plates, each capable of measuring the total load on the appropriate block of the mobile deformable barrier impactor at the moment of impact.

6.1.2.3.   Surface protection, comprising a plywood face (thickness: 12 ± 1 mm), is added to each load cell plate such that it shall not degrade the transducer responses.

6.1.2.4.   The rigid wall shall be either anchored in the ground or placed on the ground with, if necessary, additional arresting devices to limit its deflection. A rigid wall (to which the load cells are attached) having different characteristics but giving results that are at least equally conclusive may be used.

6.2.   Propulsion of the mobile deformable barrier

At the moment of impact the mobile deformable barrier shall no longer be subject to the action of any additional steering or propelling device. It shall reach the obstacle on a course perpendicular to the front surface of the dynamometric wall. Impact alignment shall be accurate to within 10 mm.

6.3.   Measuring instruments

6.4.   General specifications of barrier

6.4.1.   The individual characteristics of each barrier shall comply with paragraph 1 of this annex and shall be recorded.

6.5.   General specifications of the impactor

6.5.1.   The suitability of an impactor as regards the dynamic test requirements shall be confirmed when the outputs from the six load cell plates each produce signals complying with the requirements indicated in this annex.

6.5.2.   Impactors shall carry consecutive serial numbers which are stamped, etched or otherwise permanently attached, from which the batches for the individual blocks and the date of manufacture can be established.

6.6.   Data processing procedure

6.6.1.   Raw data: At time T = T0, all offsets should be removed from the data. The method by which offsets are removed shall be recorded in the test report.

6.6.2.   Filtering

6.6.2.1.   The raw data will be filtered prior to processing/calculations.

6.6.2.2.   Accelerometer data for integration will be filtered to CFC 180, ISO 6487:1987.

6.6.2.3.   Accelerometer data for impulse calculations will be filtered to CFC 60, ISO 6487:1987.

6.6.2.4.   Load cell data will be filtered to CFC 60, ISO 6487:1987.

6.6.3.   Calculation of MDB face deflection

6.6.3.1.   Accelerometer data from all three accelerometers individually (after filtering at CFC 180), will be integrated twice to obtain deflection of the barrier deformable element.

6.6.3.2.   The initial conditions for deflection are:

6.6.3.2.1.   Velocity= impact velocity (from speed measuring device).

6.6.3.2.2.   Deflection= 0

6.6.3.3.   The deflection at the left hand side, mid-line and right hand side of the mobile deformable barrier will be plotted with respect to time.

6.6.3.4.   The maximum deflection calculated from each of the three accelerometers should be within 10 mm. If it is not the case, then the outlier should be removed and difference between the deflections calculated from the remaining two accelerometers checked to ensure that it is within 10 mm.

6.6.3.5.   If the deflections as measured by the left hand side, right hand side and mid-line accelerometers are within 10 mm, then the mean acceleration of the three accelerometers should be used to calculate the deflection of the barrier face.

6.6.3.6.   If the deflection from only two accelerometers meets the 10 mm requirement, then the mean acceleration from these two accelerometers should be used to calculate the deflection for the barrier face.

6.6.3.7.   If the deflections calculated from all three accelerometers (left hand side, right hand side and mid-line) are NOT within the 10 mm requirement, then the raw data should be reviewed to determine the causes of such large variation. In this case the individual test house will determine which accelerometer data should be used to determine mobile deformable barrier deflection or whether none of the accelerometer readings can be used, in which case, the certification test must be repeated. A full explanation should be given in the test report.

6.6.3.8.   The mean deflection-time data will be combined with the load cell wall force-time data to generate the force-deflection result for each block.

6.6.4.   Calculation of energy

The absorbed energy for each block and for the whole MDB face should be calculated up to the point of peak deflection of the barrier.

Formula

Where:

| t0 | is the time of first contact, |
| --- | --- |
| t1 | is the time where the trolley comes to rest, i.e. where u = 0, |
| s | is the deflection of the trolley deformable element calculated according to paragraph 6.6.3. |

t0

is the time of first contact,

t1

is the time where the trolley comes to rest, i.e. where u = 0,

s

is the deflection of the trolley deformable element calculated according to paragraph 6.6.3.

6.6.5.   Verification of dynamic force data

6.6.5.1.   Compare the total impulse, I, calculated from the integration of the total force over the period of contact, with the momentum change over that period (M*)V).

6.6.5.2.   Compare the total energy change to the change in kinetic energy of the MDB, given by:

Formula

Where Vi is the impact velocity and M the whole mass of the MDB

If the momentum change (M*)V) is not equal to the total impulse (I) ± 5 per cent, or if the total energy absorbed (E En) is not equal to the kinetic energy, EK ± 5 per cent, then the test data must be examined to determine the cause of this error.

(2)  All dimensions are in mm. The tolerances on the dimensions of the blocks allow for the difficulties of measuring cut aluminium honeycomb. The tolerance on the overall dimension of the impactor is less than that for the individual blocks since the honeycomb blocks can be adjusted, with overlap if necessary, to maintain a more closely defined impact face dimension.

5.3.   Visual check

5.3.1.   All dummy parts should be visually checked for damage and if necessary replaced before the certification test.

5.4.   General test set-up

5.4.1.   Figure 3 of this annex shows the test set-up for all certification tests on the side impact dummy.

5.4.2.   The certification test set-up arrangements and testing procedures shall be in accordance with the specification and requirements of the documentation specified in paragraph 1.1.

5.4.3.   The tests on the head, neck, thorax and lumbar spine are carried out on sub-assemblies of the dummy.

5.4.4.   The tests on the shoulder, abdomen and pelvis are performed with the complete dummy (without suit, shoes and underwear). In these tests the dummy is seated on a flat surface with two sheets of less than or equal to 2 mm thick polytetrafluoroethylene (PTFE), placed between the dummy and the flat surface.

5.4.5.   All parts to be certified should be kept in the test room for a period of at least four hours at a temperature between and including 18 and 22 °C and a relative humidity between and including 10 and 70 per cent prior to a test.

5.4.6.   The time between two certification tests on the same part should be at least 30 minutes.

5.5.   Head

5.5.1.   The head sub assembly, including the upper neck load cell replacement, is certified in a drop test from 200 ± 1 mm onto a flat, rigid impact surface.

5.5.2.   The angle between the impact surface and the mid-sagittal plane of the head is 35 ± 1° allowing an impact to the upper part of the head side (this can be realised with a sling harness or a head drop support bracket with a mass of 0,075 ± 0,005 kg).

5.5.3.   The peak resultant head acceleration, filtered using ISO 6487:2000 CFC 1000, should be between and including 100 g and 150 g.

5.5.4.   The head performance can be adjusted to meet the requirement by altering the friction characteristics of the skin-skull interface (e.g. by lubrication with talcum powder or polytetrafluoroethylene (PTFE) spray).

5.6.   Neck

5.6.1.   The head-neck interface of the neck is mounted to a special certification head-form with a mass of 3,9 ± 0,05 kg (see Figure 6), with the help of a 12 mm thick interface plate with a mass of 0,205 ± 0,05 kg.

5.6.2.   The head-form and neck are mounted upside-down to the bottom of a neck- pendulum (2) allowing a lateral motion of the system.

5.6.3.   The neck-pendulum is equipped with a uni-axial accelerometer according to the neck pendulum specification (see Figure 5).

5.6.4.   The neck-pendulum should be allowed to fall freely from a height chosen to achieve an impact velocity of 3,4 ± 0,1 m/s measured at the pendulum accelerometer location.

5.6.5.   The neck-pendulum is decelerated from impact velocity to zero by an appropriate device (3), as described in the neck pendulum specification (see Figure 5), resulting in a velocity change — time history inside the corridor specified in Figure 7 and Table 4 of this annex. All channels have to be recorded according to the ISO 6487:2000 or SAE J211 (March 1995) data channel recording specification and filtered digitally using ISO 6487:2000 CFC 180 or SAE J211:1995 CFC 180.

ANNEX 7

INSTALLATION OF THE SIDE IMPACT DUMMY

1.   GENERAL

1.1.   The side impact dummy as described in Annex 6 to this Regulation is to be used according the following installation procedure.

2.   INSTALLATION

2.1.   Adjust the knee and ankle joints so that they just support the lower leg and the foot when extended horizontally (1 to 2 g — adjustment).

2.2.   Check if the dummy is adapted to the desired impact direction.

2.3.   The dummy shall be clothed in a form-fitting cotton stretch mid-calf length pant and may be clothed in a form-fitting cotton stretch shirt with short sleeves.

2.4.   Each foot shall be equipped with a shoe.

2.5.   Place the dummy in the outboard front seat of the impacted side as described in the side impact test procedure specification.

2.6.   The plane of symmetry of the dummy shall coincide with the vertical median plane of the specified seating position.

2.7.   The pelvis of the dummy shall be positioned such that a lateral line passing through the dummy H-points is perpendicular to the longitudinal centre plane of the seat. The line through the dummy H-points shall be horizontal with a maximum inclination of ± 2° (1).

The correct position of the dummy pelvis can be checked relative to the H-point of the H-point Manikin by using the M3 holes in the H-point back plates at each side of the ES-2 pelvis. The M3 holes are indicated with ‘Hm’. The ‘Hm’ position should be in a circle with a radius of 10 mm round the H-point of the H-point Manikin.

The correct position of the dummy pelvis

2.8.   The upper torso shall be bent forward and then laid back firmly against the seat back (see note 1). The shoulders of the dummy shall be set fully rearward.

2.9.   Irrespective of the seating position of the dummy, the angle between the upper arm and the torso arm reference line on each side shall be 40° ± 5°. The torso arm reference line is defined as the intersection of the plane tangential to the front surface of the ribs and the longitudinal vertical plane of the dummy containing the arm.

2.10.   For the driver's seating position, without inducing pelvis or torso movement, place the right foot of the dummy on the non-depressed accelerator pedal with the heel resting as far forward as possible on the floor-pan. Set the left foot perpendicular to the lower leg with the heel resting on the floor-pan in the same lateral line as the right heel. Set the knees of the dummy such that their outside surfaces are 150 ± 10 mm from the plane of symmetry of the dummy. If possible within these constraints place the thighs of the dummy in contact with the seat cushion.

2.11.   For other seating positions, without inducing pelvis or torso movement, place the heels of the dummy as far forward as possible on the floor-pan without compressing the seat cushion more than the compression due to the weight of the leg. Set the knees of the dummy such that their outside surfaces are 150 ± 10 mm from the plane of symmetry of the dummy.

---

(1)  The dummy can be equipped with tilt sensors in the thorax and the pelvis. These instruments can help to obtain the desired position.

ANNEX 9

TEST PROCEDURES FOR THE PROTECTION OF THE OCCUPANTS OF VEHICLES OPERATING ON ELECTRICAL POWER HIGH VOLTAGE AND ELECTROLYTE SPILLAGE

This annex describes test procedures to demonstrate compliance to the electrical safety requirements of paragraph 5.3.7. For example, megohmmeter or oscilloscope measurements are an appropriate alternative to the procedure described below for measuring isolation resistance. In this case it may be necessary to deactivate the on-board isolation resistance monitoring system.

Before the vehicle impact test conducted, the high voltage bus voltage (Vb) (see Figure 1) shall be measured and recorded to confirm that it is within the operating voltage of the vehicle as specified by the vehicle manufacturer.

1.   TEST SETUP AND EQUIPMENT

If a high voltage disconnect function is used, measurements are to be taken from both sides of the device performing the disconnect function.

However, if the high voltage disconnect is integral to the REESS or the energy conversion system and the high-voltage bus of the REESS or the energy conversion system is protected according to protection degree IPXXB following the impact test, measurements may only be taken between the device performing the disconnect function and the electrical loads.

The voltmeter used in this test shall measure DC values and have an internal resistance of at least 10 MΩ.

2.   THE FOLLOWING INSTRUCTIONS MAY BE USED IF VOLTAGE IS MEASURED.

After the impact test, determine the high voltage bus voltages (Vb, V1, V2) (see Figure 1).

The voltage measurement shall be made not earlier than 5 seconds, but, not later than 60 seconds after the impact.

This procedure is not applicable if the test is performed under the condition where the electric power train is not energised.

Not earlier than 5 seconds and not later than 60 seconds after the impact the switch S1 shall be closed while the voltage Vb and the current Ie are measured and recorded. The product of the voltage Vb and the current Ie shall be integrated over the period of time, starting from the moment when the switch S1 is closed (tc) until the voltage Vb falls below the high voltage threshold of 60 V DC (th). The resulting integration equals the total energy (TE) in joules.

4.   PHYSICAL PROTECTION

Following the vehicle impact test any parts surrounding the high voltage components shall be, without the use of tools, opened, disassembled or removed. All remaining surrounding parts shall be considered part of the physical protection.

The jointed test finger described in the figure of the appendix to this annex shall be inserted into any gaps or openings of the physical protection with a test force of 10 N ± 10 per cent for electrical safety assessment. If partial or full penetration into the physical protection by the jointed test finger occurs, the jointed test finger shall be placed in every position as specified below.

Starting from the straight position, both joints of the test finger shall be rotated progressively through an angle of up to 90° with respect to the axis of the adjoining section of the finger and shall be placed in every possible position.

Internal electrical protection barriers are considered part of the enclosure.

If appropriate a low-voltage supply (of not less than 40 V and not more than 50 V) in series with a suitable lamp should be connected, between the jointed test finger and high voltage live parts inside the electrical protection barrier or enclosure.

4.1.   Acceptance conditions

The requirements of paragraph 5.3.7.1.3 shall be considered to be met if the jointed test finger described in the figure of the appendix to this annex is unable to contact high voltage live parts.

If necessary a mirror or a fiberscope may be used in order to inspect whether the Jointed Test Finger touches the high voltage buses.

If this requirement is verified by a signal circuit between the jointed test finger and high voltage live parts, the lamp shall not light.

5.   ISOLATION RESISTANCE

The isolation resistance between the high voltage bus and the electrical chassis may be demonstrated either by measurement or by a combination of measurement and calculation.

The following instructions should be used if the isolation resistance is demonstrated by measurement.

| | Measure and record the voltage (Vb) between the negative and the positive side of the high voltage bus (see Figure 1); |
| --- | --- |

Measure and record the voltage (Vb) between the negative and the positive side of the high voltage bus (see Figure 1);

| --- | --- |

Measure and record the voltage (V2) between the positive side of the high voltage bus and the electrical chassis (see Figure 1);

If V1 is greater than or equal to V2, insert a standard known resistance (Ro) between the negative side of the high voltage bus and the electrical chassis. With Ro installed, measure the voltage (V1′) between the negative side of the high voltage bus and the vehicle electrical chassis (see Figure 3). Calculate the isolation resistance (Ri) according to the formula shown below.

Note: The standard known resistance Ro (in Ω) should be the value of the minimum required isolation resistance (in Ω/V) multiplied by the working voltage (in V) of the vehicle plus/minus 20 per cent. Ro is not required to be precisely this value since the equations are valid for any Ro; however, a Ro value in this range should provide a good resolution for the voltage measurements.

6.   ELECTROLYTE SPILLAGE

Appropriate coating shall be applied, if necessary, to the physical protection in order to confirm any electrolyte leakage from the REESS after the impact test.

Unless the manufacturer provides means to differentiate between the leakage of different liquids, all liquid leakage shall be considered as the electrolyte.

7.   REESS RETENTION COMPLIANCE SHALL BE DETERMINED BY VISUAL INSPECTION.
