   4.8.   The approval mark shall be placed close to or on the vehicle data plate affixed by the manufacturer.
   4.9.   Annex 2 to this Regulation gives examples of approval marks.
   5.   SPECIFICATIONS AND TESTS
   5.1.   The vehicle shall undergo a test in accordance with Annex 4 to this Regulation.
   5.1.1.   The test will be carried out on the driver’s side unless asymmetric side structures, if any, are so different as to affect the performance in a side impact. In that case either of the alternatives in paragraph 5.1.1.1 or 5.1.1.2 may be used by agreement between the manufacturer and test authority.
   5.1.1.1.   The manufacturer will provide the authority responsible for approval with information regarding the compatibility of performances in comparison with the driver’s side when the test is being carried out on that side.
   5.1.1.2.   The approval authority, if concerned as to the construction of the vehicle, will decide to have the test performed on the side opposite the driver, this being considered the least favourable.
   5.1.2.   The Technical Service, after consultation with the manufacturer, may require the test to be carried out with the seat in a position other than the one indicated in paragraph 5.5.1 of Annex 4. This position shall be indicated in the test report (2).
   5.1.3.   The result of this test shall be considered satisfactory if the conditions set out in paragraphs 5.2 and 5.3 are satisfied.
   5.2.   Performance criteria
   
   5.2.1.   The performance criteria, as determined for the collision test in accordance with the Appendix to Annex 4 to this Regulation shall meet the following conditions:
   5.2.1.1.   the head performance criterion (HPC) shall be less than or equal to 1 000; when there is no head contact, then the HPC shall not be measured or calculated but recorded as ‘no head contact’;
   5.2.1.2.   the thorax performance criteria shall be:
   
               (a)
            
            
               rib deflection criterion (RDC) less than or equal to 42 mm;
            
         
               (b)
            
            
               soft tissue criterion (VC) less or equal to 1,0 m/sec.
            
         For a transitional period of two years after the date specified in paragraph 10.2 of this Regulation the V * C value is not a pass/fail criterion for the approval testing, but this value has to be recorded in the test report and to be collected by the approval authorities. After this transitional period, the VC value of 1,0 m/sec shall apply as a pass/fail criterion unless the Contracting Parties applying this Regulation decide otherwise;
   5.2.1.3.   the pelvis performance criterion shall be:
   pubic symphysis peak force (PSPF) less than or equal to 6 kN;
   5.2.1.4.   the abdomen performance criterion shall be:
   abdominal peak force (APF) less than or equal to 2,5 kN internal force (equivalent to external force of 4,5 kN).
   5.3.   Particular requirements
   
   5.3.1.   No door shall open during the test.
   5.3.2.   After the impact, it shall be possible without the use of tools to:
   5.3.2.1.   open a sufficient number of doors provided for normal entry and exit of passengers, and if necessary tilt the seat-backs or seats to allow evacuation of all occupants;
   5.3.2.2.   release the dummy from the protective system;
   5.3.2.3.   remove the dummy from the vehicle;
   5.3.3.   no interior device or component shall become detached in such a way as noticeably to increase the risk of injury from sharp projections or jagged edges;
   5.3.4.   ruptures, resulting from permanent deformation are acceptable, provided these do not increase the risk of injury;
   5.3.5.   if there is continuous leakage of liquid from the fuel-feed installation after the collision, the rate of leakage shall not exceed 30 g/min; if the liquid from the fuel-feed system mixes with liquids from the other systems and the various liquids cannot easily be separated and identified, all the liquids collected shall be taken into account in evaluating the continuous leakage.
   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 administrative department granting approval. The department 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 % 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 % 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 to the Parties to the Agreement which apply this Regulation.
   6.3.   The competent 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
   The conformity of production procedures shall comply with those set out in the Agreement, Appendix 2 (E/ECE/324-E/ECE/TRANS/505/Rev.2), with the following requirements:
   7.1.   Every vehicle approved under this Regulation shall be so manufactured as to conform to the type approved by meeting the requirements set out in paragraph 5.
   7.2.   The holder of the approval shall ensure that for each type of vehicle at least the tests concerning the taking of measurements are carried out.
   7.3.   The 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 two 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.
   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 DEFINITELY 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 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.
   10.   TRANSITIONAL PROVISIONS
   10.1.   As from the official date of entry into force of the 02 series of amendments, no Contracting Party applying this Regulation shall refuse to grant ECE approval under this Regulation as amended by the 02 series of amendments.
   10.2.   As from 12 months after the entry into force of the 02 series of amendments Contracting Parties applying this Regulation shall grant ECE approvals only to those types of vehicles which comply with the requirements of this Regulation as amended by the 02 series of amendments.
   10.3.   As from 60 months after the entry into service of the 02 series of amendments Contracting Parties applying this Regulation may refuse first national registration (first entry into service) of vehicles which do not meet the requirements of this Regulation as amended by the 02 series of amendments.
   11.   NAMES AND ADDRESSES OF TECHNICAL SERVICES RESPONSIBLE FOR CONDUCTING APPROVAL TESTS, AND OF ADMINISTRATIVE DEPARTMENTS

   ANNEX 3
   Procedure for determining the ‘H’ point and the actual torso angle for seating positions in motor vehicles
   1.   PURPOSE
   The procedure described in this Annex is used to establish the ‘H’ point location and the actual torso angle for one or several seating positions in a motor vehicle and to verify the relationship of measured data to design specifications given by the vehicle manufacturer (1).
   2.   DEFINITIONS
   For the purposes of this Annex:
   2.1.   ‘reference data’ means one or several of the following characteristics of a seating position:
   2.1.1.   the ‘H’ point and the ‘R’ point and their relationship,
   2.1.2.   the actual torso angle and the design torso angle and their relationship.
   2.2.   ‘three-dimensional “H” point machine’ (3-D H machine) means the device used for the determination of ‘H’ points and actual torso angles. This device is described in Appendix 1 to this Annex;
   2.3.   ‘ “H” point’ means the pivot centre of the torso and the thigh of the 3-D H machine installed in the vehicle seat in accordance with paragraph 4 below. The ‘H’ point is located in the centre of the centreline of the device which is between the ‘H’ point sight buttons on either side of the 3-D H machine. The ‘H’ point corresponds theoretically to the ‘R’ point (for tolerances see paragraph 3.2.2). Once determined in accordance with the procedure described in paragraph 4, the ‘H’ point is considered fixed in relation to the seat-cushion structure and to move with it when the seat is adjusted;
   2.4.   ‘ “R” point’ or ‘seating reference point’ means a design point defined by the vehicle manufacturer for each seating position and established with respect to the three-dimensional reference system;
   2.5.   ‘torso-line’ means the centreline of the probe of the 3-D H machine with the probe in the fully rearward position;
   2.6.   ‘actual torso angle’ means the angle measured between a vertical line through the ‘H’ point and the torso line using the back angle quadrant on the 3-D H machine. The actual torso angle corresponds theoretically to the design torso angle (for tolerances see paragraph 3.2.2):
   2.7.   ‘design torso angle’ means the angle measures between a vertical line through the ‘R’ point and the torso line in a position which corresponds to the design position of the seat-back established by the vehicle manufacturer;
   2.8.   ‘centreplane of occupant’ (C/LO) means the median plane of the 3-D H machine positioned in each designated seating position; it is represented by the coordinate of the ‘H’ point on the ‘Y’ axis. For individual seats, the centreplane of the seat coincides with the centreplane of the occupant. For other seats, the centreplane of the occupant is specified by the manufacturer;
   2.9.   ‘three-dimensional reference system’ means a system as described in Appendix 2 to this Annex;
   2.10.   ‘fiducial marks’ are physical points (holes, surfaces, marks or indentations) on the vehicle body as defined by the manufacturer;
   2.11.   ‘vehicle measuring attitude’ means the position of the vehicle as defined by the coordinates of fiducial marks in the three-dimensional reference system.
   3.   REQUIREMENTS
   3.1.   Data presentation
   
   For each seating position where reference data are required in order to demonstrate compliance with the provisions of the present Regulation, all or an appropriate selection of the following data shall be presented in the form indicated in Appendix 3 to this Annex:
   3.1.1.   the coordinates of the ‘R’ point relative to the three-dimensional reference system;
   3.1.2.   the design torso angle;
   3.1.3.   all indications necessary to adjust the seat (if it is adjustable) to the measuring position set out in paragraph 4.3.
   3.2.   Relationship between measured data and design specifications
   
   3.2.1.   The coordinates of the ‘H’ point and the value of the actual torso angle obtained by the procedure set out in paragraph 4 shall be compared, respectively, with the coordinates of the ‘R’ point and the value of the design torso angle indicated by the vehicle manufacturer.
   3.2.2.   The relative positions of the ‘R’ point and the ‘H’ point and the relationship between the design torso angle and the actual torso angle shall be considered satisfactory for the seating position in question if the ‘H’ point, as defined by its coordinates, lies within a square of 50 mm side length with horizontal and vertical sides whose diagonals intersect at the ‘R’ point, and if the actual torso angle is within 5° of the design torso angle.
   3.2.3.   If these conditions are met, the ‘R’ point and the design torso angle, shall be used to demonstrate compliance with the provisions of this Regulation.
   3.2.4.   If the ‘H’ point or the actual torso angle does not satisfy the requirements of paragraph 3.2.2, the ‘H’ point and the actual torso angle shall be determined twice more (three times in all). If the results of two of these three operations satisfy the requirements, the conditions of paragraph 3.2.3 shall apply.
   3.2.5.   If the results of at least two of the three operations described in paragraph 3.2.4 do not satisfy the requirements of paragraph 3.2.2, or if the verification cannot take place because the vehicle manufacturer has failed to supply information regarding the position of the ‘R’ point or regarding the design torso angle, the centroid of the three measured points or the average of the three measured angles shall be used and be regarded as applicable in all cases where the ‘R’ point or the design torso angle is referred to in this Regulation.
   4.   PROCEDURE FOR ‘H’ POINT AND ACTUAL TORSO ANGLE DETERMINATION
   4.1.   The vehicle shall be preconditioned at the manufacturer’s discretion, at a temperature of 20 ± 10 °C to ensure that the seat material reached room temperature. If the seat to be checked has never been sat upon, a 70 to 80 kg person or device shall sit on the seat twice for one minute to flex the cushion and back. At the manufacturer’s request, all seat assemblies shall remain unloaded for a minimum period of 30 minutes prior to installation of the 3-D H machine.
   4.2.   The vehicle shall be at the measuring attitude defined in paragraph 2.11.
   4.3.   The seat, if it is adjustable, shall be adjusted first to the rearmost normal driving or riding position, as indicated by the vehicle manufacturer, taking into consideration only the longitudinal adjustment of the seat, excluding seat travel used for purposes other than normal driving or riding positions. Where other modes of seat adjustment exist (vertical, angular, seat-back, etc.) these will then be adjusted to the position specified by the vehicle manufacturer. For suspension seats, the vertical position shall be rigidly fixed corresponding to a normal driving position as specified by the manufacturer.
   4.4.   The area of the seating position contacted by the 3-D H machine shall be covered by a muslin cotton, of sufficient size and appropriate texture, described as a plain cotton fabric having 18.9 threads per cm2 and weighing 0.228 kg/m2 or knitted or non-woven fabric having equivalent characteristics. If the test is run on a seat outside the vehicle, the floor on which the seat is placed shall have the same essential characteristics (2) as the floor of the vehicle in which the seat is intended to be used.
   4.5.   Place the seat and back assembly of the 3-D H machine so that the centreplane of the occupant (C/LO) coincides with the centreplane of the 3-D H machine. At the manufacturer’s request, the 3-D H machine may be moved inboard with respect to the C/LO if the 3-D H machine is located so far outboard that the seat edge will not permit levelling of the 3-D H machine.
   4.6.   Attach the foot and lower leg assemblies to the seat pan assembly, either individually or by using the T-bar and lower leg assembly. A line through the ‘H’ point sight buttons shall be parallel to the ground and perpendicular to the longitudinal centreplane of the seat.
   4.7.   Adjust the feet and leg positions of the 3-D H machine as follows:
   4.7.1.   Designated seating position: driver and outside front passenger
   4.7.1.1.   Both feet and leg assemblies shall be 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 shall be located approximately the same distance to the left of the centreplane 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 shall be maintained perpendicular to the longitudinal centreplane of the seat.
   4.7.1.2.   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 shall be maintained.
   4.7.2.   Designated seating position: outboard rear
   For rear seats or auxiliary seats, the legs are located as specified by the manufacturer. If the feet then rest on parts of the floor which are at different levels, the foot which first comes into contact with the front seat shall serve as a reference and the other foot shall be so arranged that the spirit level giving the transverse orientation of the seat of the device indicates the horizontal.
   4.7.3.   Other designated seating positions:
   The general procedure indicated in paragraph 4.7.1 shall be followed except that the feet shall be placed as specified by the vehicle manufacturer.
   4.8.   Apply lower leg and thigh weights and level the 3-D H machine.
   4.9.   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:
   4.9.1.   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.
   4.9.2.   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 2 of Appendix 1 to this Annex).
   4.10.   Apply a 100 ± 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 shall be maintained along a line passing by the above intersection to a point just above the thigh bar housing (see Figure 2 of Appendix 1 to this Annex). 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.
   4.11.   Install the right and left buttock weights and then, alternately, the eight torso weights.
   Maintain the 3-D H machine level.
   4.12.   Tilt the back pan forward to release the tension on the seat-back. Rock the 3-D H machine from side to side through a 10° arc (5° to each side of the vertical centreplane) for three complete cycles to release any accumulated friction between the 3-D H machine and the seat.
   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 shall be 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 direction.
   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.
   Carefully return the back pan to the seat-back and check the two spirits 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:
   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.
   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.
   4.13.   Holding the T-bar to prevent the 3-D H machine from sliding forward on the seat cushion, proceed as follows:
   
               (a)
            
            
               return the back pan to the seat-back;
            
         
               (b)
            
            
               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 shall be 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 the procedure from paragraph 4.12.
            
         4.14.   Take all measurements:
   4.14.1.   The coordinates of the ‘H’ point are measured with respect to the three-dimensional reference system.
   4.14.2.   The actual torso angle is read at the back angle quadrant of the 3-D H machine with the probe in its fully rearward position.
   4.15.   If a re-run of the installation of the 3-D H machine is desired, the seat assembly should remain unloaded for a minimum period of 30 min prior to the re-run. The 3-D H machine should not be left loaded on the seat assembly longer than the time required to perform the test.
   4.16.   If the seats in the same row can be regarded as similar (bench seat, identical seats, etc.) only one ‘H’ point and one ‘actual torso angle’ shall be determined for each row of seats, the 3-D H machine described in Appendix 1 to this Annex being seated in a place regarded as representative for the row. This place shall be:
   4.16.1.   in the case of the front row, the driver’s seat;
   4.16.2.   in the case of the rear row or rows, an outer seat.
   
      (1)  In any seating position other than front seats where the ‘H’ point cannot be determined using the ‘three-dimensional “H” point machine’ or procedures, the ‘R’ point indicated by the manufacturer may be taken as a reference at the discretion of the competent authority.
   
      (2)  Tilt angle, height difference with a seat mounting, surface texture, etc.
   Appendix 1
   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.

   Three-dimensional reference system
   1.   The three-dimensional reference system is defined by three orthogonal planes established by the vehicle manufacturer (1).
   2.   The vehicle measuring attitude is established by positioning the vehicle on the supporting surface such that the coordinates of the fiducial marks correspond to the values indicated by the manufacturer.
   3.   The coordinates of the ‘R’ point and the ‘H’ point are established in relation to the fiducial marks defined by the vehicle manufacturer.
   
      
   
      (1)  The reference system corresponds to ISO standard 4130, 1978.
   Appendix 3
   Reference data concerning seating positions

   3.   TEST SPEED
   The mobile deformable barrier speed at the moment of impact shall be 50 ± 1 km/h. This speed shall be stabilised at least 0,5 m before impact. Accuracy of measurement: 1 %. However, if the test was performed at a higher impact speed and the vehicle met the requirements, the test shall be considered satisfactory.
   4.   STATE OF THE VEHICLE
   4.1.   General specification
   
   The test vehicle shall be representative of the series production, shall include all the equipment normally fitted and shall be in normal running order. Some components may be omitted or replaced by equivalent masses where this omission or substitution clearly has no effect on the results of the test.
   4.2.   Vehicle equipment specification
   
   The test vehicle shall have all the optional arrangements or fittings likely to influence the results of the test.
   4.3.   Mass of the vehicle
   
   4.3.1.   The vehicle to be tested shall have the reference mass as defined in paragraph 2.10 of this Regulation. The mass of the vehicle shall be adjusted to ± 1 % of the reference mass.

   5.2.   The doors shall be closed, but not locked.
   5.3.   The transmission shall be placed in neutral and the parking brake disengaged.
   5.4.   The comfort adjustments of the seats, if any, shall be adjusted to the position specified by the vehicle manufacturer.
   5.5.   The seat containing the dummy, and its elements, if adjustable, shall be adjusted as follows:
   5.5.1.   the longitudinal adjustment device shall be placed with the locking device engaged in the position that is nearest to midway between the foremost and rearmost positions; if this position is between two notches, the rearmost notch shall be used;
   5.5.2.   the head restraint shall be adjusted such that its top surface is level with the centre of gravity of the dummy’s head; if this is not possible, the head restraint shall be in the uppermost position;
   5.5.3.   unless otherwise specified by the manufacturer, the seat-back shall be set such that the torso reference line of the three-dimensional H point machine is set at an angle of 25 ± 1° towards the rear;
   5.5.4.   all other seat adjustments shall be at the mid-point of available travel; however, height adjustment shall be at the position corresponding to the fixed seat, if the vehicle type is available with adjustable and fixed seats. If locking positions are not available at the respective mid-points of travel, the positions immediately rearward, down, or outboard of the mid-points shall be used. For rotational adjustments (tilt), rearward will be the adjustment direction which moves the head of the dummy rearwards. If the dummy protrudes outside the normal passenger volume, e.g. head into roof lining, then 1 cm clearance will be provided using: secondary adjustments, seat-back angle, or fore-aft adjustment in that order.
   5.6.   Unless otherwise specified by the manufacturer, the other front seats shall, if possible, be adjusted to the same position as the seat containing the dummy.
   5.7.   If the steering wheel is adjustable, all adjustments are positioned to their mid-travel locations.
   5.8.   Tyres shall be inflated to the pressure specified by the vehicle manufacturer.
   5.9.   The test vehicle shall be set horizontal about its roll axis and maintained by supports in that position until the side impact dummy is in place and after all preparatory work is complete.
   5.10.   The vehicle shall be at its normal attitude corresponding to the conditions set out in paragraph 4.3. Vehicles with suspension enabling their ground clearance to be adjusted shall be tested under the normal conditions of use at 50 km/h as defined by the vehicle manufacturer. This shall be assured by means of additional supports, if necessary, but such supports shall have no influence on the crash behaviour of the test vehicle during the impact.
   6.   SIDE IMPACT DUMMY AND ITS INSTALLATION
   6.1.   The side impact dummy shall comply with the specifications given in Annex 6 and be installed in the front seat on the impact side according to the procedure given in Annex 7 to this Regulation.
   6.2.   The safety-belts or other restraint systems, which are specified for the vehicle, shall be used. Belts should be of an approved type, conforming to Regulation No 16 or to other equivalent requirements and mounted on anchorages conforming to Regulation No 14 or to other equivalent requirements.
   6.3.   The safety-belt or restraint system shall be adjusted to fit the dummy in accordance with the manufacturer’s instructions; if there are no manufacturer’s instructions, the height adjustment shall be set at middle position; if this position is not available, the position immediately below shall be used.
   7.   MEASUREMENTS TO BE MADE ON THE SIDE IMPACT DUMMY
   7.1.   The readings of the following measuring devices are to be recorded.
   7.1.1.   Measurements in the head of the dummy
   
   The resultant triaxial acceleration referring to the head centre of gravity. The head channel instrumentation shall comply with ISO 6487:1987 with: CFC: 1 000 Hz, and CAC: 150 g

   Determination of performance data
   The required results of the tests are specified in paragraph 5.2 of this Regulation.
   1.   HEAD PERFORMANCE CRITERION (HPC)
   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:
   
      
   where a is the resultant acceleration at the centre of gravity of the head in metres per second 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.
   
      
   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 symphysis 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):
   
      
   The rib deflection velocity at time ∂(t) is calculated from the filtered deflection as:
   
      
   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.

   The conformity of production procedures shall comply with those set out in the Agreement, Appendix 2 (E/ECE/324-E/ECE/TRANS/505/Rev.2), with the following requirements:
   4.1.   The manufacturer shall be responsible for the conformity of production procedures and for that purpose must in particular:
   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 three 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 that the block cross section.
   5.4.   The compression speed shall be 100 millimetres per minute, with a tolerance of 5 %.
   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.

   6.1.2.1.   The rigid wall shall consist of a block of reinforced concrete not less than three metres wide and not less than 1,5 metres high. The thickness of the rigid wall shall be such that it weighs at least 70 tonnes.
   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. The load cell impact plate area centres shall align with those of the six impact zones of the mobile deformable barrier face. Their edges shall clear adjacent areas by 20 mm such that, within the tolerance of impact alignment of the MDB, the impact zones will not contact the adjacent impact plate areas. Cell mounting and plate surfaces shall be in accordance with the requirements set out in the Annex to standard ISO 6487:1987.
   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.

   6.5.2.   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 deflection 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.
   
      
   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.
            
         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:
   
      
   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 %, or if the total energy absorbed (E En) is not equal to the kinetic energy, EK ± 5 %, then the test data must be examined to determine the cause of this error.

   Ventilation frame
   The ventilation device is a structure made of a plate that is 5 mm thick and 20 mm wide. Only the vertical plates are perforated with nine 8 mm holes in order to let air circulate horizontally.
   
      
   
      (1)  The amounts of energy indicated are the amounts of energy dissipated by the system when the extent to which the impactor is crushed is greatest.
   
      (2)  All dimensions are in mm. The tolerances on the dimensins 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.   CERTIFICATION OF THE DUMMY
   5.1.   Impact side
   
   5.1.1.   Depending on the vehicle side to be impacted, dummy parts should be certified on the left hand side or right hand side.
   5.1.2.   The configurations of the rib modules (including instrumentation), the abdominal force transducers and the pubic symphysis transducer have to be converted to the required impact side.
   5.2.   Instrumentation
   
   All instrumentation shall be calibrated in compliance with the requirements of the documentation specified in paragraph 1.3.
   5.2.1.   All instrumentation channels shall comply with ISO 6487: 1987.
   5.3.   Visual check
   
   5.3.1.   All dummy parts should be visually checked for damage and if necessary be 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 tests on the head, neck, thorax and lumbar spine are carried out on disassembled parts of the dummy.
   5.4.3.   The tests on the shoulder, abdomen and pelvis are performed with the complete dummy (without suit). In these tests the dummy is seated on a flat surface with two sheets of less than or equal to 2 mm thick Teflon, placed between the dummy and the surface.
   5.4.4.   All parts to be certified should be kept in the test room for a period of at least four hours at a temperature between 18 °C and 22 °C prior to a test.
   5.4.5.   The time between two repeated certification tests should be at least 30 minutes.
   5.5.   Head
   
   5.5.1.   The head is dropped 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 of the upper-side of the head.
   5.5.3.   The peak resultant head acceleration, filtered using CFC 1000, should be between 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 flesh-skull interface (e.g. by lubrication with talcum powder or PTFE spray).
   5.6.   Neck
   
   5.6.1.   The head-neck interface of the neck is mounted to a special symmetrical certification headform with a mass of 3,9 ± 0,05 kg (see Figure 4).
   5.6.2.   The head form and neck are mounted upside-down to the bottom of a neck-bending pendulum allowing a lateral motion of the system.
   5.6.3.   The neck-pendulum is equipped with a uniaxial accelerometer mounted at 1655 ± 5 mm from the pendulum pivot.
   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 accelerometer location.
   5.6.5.   The neck-pendulum is decelerated from impact velocity to zero by an appropriate device, resulting in a deceleration-time history inside the corridor specified in Figure 5 of this Annex. All measured rotations are recorded using CFC 1 000 filters. All measured rotations are filtered digitally, using ISO CFC 180. The pendulum deceleration is filtered with CFC 60.
   5.6.6.   The maximum head form flexion angle relative to the pendulum should be 51 ± 5° and should occur between 50 and 62 ms.
   5.6.7.   The maximum fore (A) and aft (B) neck base angles should be 32,0 ± 2,0° and 28,0 ± 2,0° respectively. These maxima should occur between 50 and 60 ms.
   5.6.8.   The neck performance can be adjusted by replacing the circular section buffers with buffers of a different shore hardness.
   5.7.   Shoulder
   
   5.7.1.   The length of the elastic cord should be adjusted so that a force between 27,5 N and 32,5 N applied in a forward direction 4 ± 1 mm from the outer edge of the clavicle in the same plane as the clavicle movement, is required to move the clavicle forward.
   5.7.2.   The dummy is seated on a flat, horizontal, rigid surface with no back support. The thorax is positioned vertically and the arms should be set at an angle of 40° ± 2° forward to the vertical. The legs are positioned horizontally.
   5.7.3.   The impactor is a pendulum of 23,5 – 0,0/+0,2 kg and 152 ± 2 mm diameter. The impactor is suspended from a rigid support by four wires with the centre line of the impactor at least 3,5 m below the rigid support.
   5.7.4.   The impactor is equipped with an accelerometer sensitive in the direction of impact and located on the impactor axis.
   5.7.5.   The impactor should freely swing onto the shoulder of the dummy with an impact velocity of 4,3 ± 0,1 m/s.
   5.7.6.   The impact direction is perpendicular to the anterior-posterior axis of the dummy and the axis of the impactor coincides with the axis of the upper arm pivot.
   5.7.7.   The peak acceleration of the impactor, filtered using CFC 180, should be between 7,5 and 10,5 g.
   5.8.   Arms
   
   5.8.1.   No dynamic certification procedure is defined for the arms.
   5.9.   Thorax
   
   5.9.1.   Each rib module is certified separately.
   5.9.2.   The rib module is positioned vertically in a drop test rig and the rib cylinder is clamped rigidly onto the rig.
   5.9.3.   The impactor is a free fall mass of 7,8 – 0,0/+0.1 kg with a flat face and a diameter of 150 ± 2 mm.
   5.9.4.   The centre line of the impactor should be aligned with the centre line of the rib’s piston.
   5.9.5.   The impact velocity is 1,0, 2,0, 3,0 and 4,0 m/s respectively. Impact velocities should not vary from those specified by more than 2 %.
   5.9.6.   The rib displacement should be measured, for instance using the rib’s own displacement transducer.
   5.9.7.   The rib certification requirements are shown in Table 4 of this Annex.
   5.9.8.   The performance of the rib module can be adjusted by replacing the tuning spring inside the cylinder with one of a different stiffness.

   2.7.   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.
   2.8.   For the driver’s seating position, without inducing pelvis or torso movement, place the right foot of the dummy on the undepressed accelerator pedal with the heel resting as far forward as possible on the floorpan. Set the left foot perpendicular to the lower leg with the heel resting on the floorpan 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 contraints place the thighs of the dummy in contact with the seat cushion.
   2.9.   For other seating positions, without inducing pelvis or torso movement, place the heels of the dummy as far forward as possible on the floorpan 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.
   ANNEX 8
   Partial test
   1.   PURPOSE
   The purpose of these tests is to verify whether the modified vehicle presents at least the same (or better) energy absorption characteristics than the vehicle type approved under this Regulation.
   2.   PROCEDURES AND INSTALLATIONS
   2.1.   Reference tests
   
   2.1.1.   Using the initial padding materials tested during the approval of the vehicle, mounted in a new lateral structure of the vehicle to be approved, two dynamic tests, utilizing two different impactors shall be carried out (Figure 1).
   2.1.1.1.   The head form impactor, defined in paragraph 3.1.1, shall hit at 24,1 km/h, in the area impacted for the Eurosid head during the approval of the vehicle. Test result shall be recorded, and the HPC calculated. However, this test shall not be carried out when, during the tests described in Annex 4 of this Regulation:
   where there has been no head contact, or
   when the head contacted the window glazing only, provided that the window glazing is not laminated glass.
   2.1.1.2.   The body block impactor, defined in paragraph 3.2.1., shall hit at 24,1 km/h in the lateral area impacted by the Eurosid shoulder, arm and thorax, during the approval of the vehicle. Test result shall be recorded, and the HPC calculated.
   2.2.   Approval test
   
   2.2.1.   Using the new padding materials, seat, etc. presented for the approval extension, and mounted in a new lateral structure of the vehicle, tests specified in paragraphs 2.1.1.1 and 2.1.1.2, shall be repeated, the new results recorded, and their HPC calculated.
   2.2.1.1.   If the HPC calculated from the results of both approval tests are lower than the HPC obtained during the reference tests (carried out using the original type approved padding materials or seats), the extension shall be granted.
   2.2.1.2.   If the new HPC are greater than the HPC obtained during the reference tests, a new full scale test (using the proposed padding/seats/etc.) shall be carried out.
   3.   TEST EQUIPMENT
   3.1.   Head form impactor (Figure 2)
   3.1.1.   This apparatus consists of a fully guided linear impactor, rigid, with a mass of 6,8 kg. Its impact surface is hemispherical with a diameter of 165 mm.
   3.1.2.   The head form shall be fitted with two accelerometers and a speed-measuring device, all capable of measuring values in the impact direction.
   3.2.   Body block impactor (Figure 3)
   3.2.1.   This apparatus consists of a fully guided linear impactor, rigid, with a mass of 30 kg. Its dimensions and transversal section is presented in Figure 3.
   3.2.2.   The body block shall be fitted with two accelerometers and a speed-measuring device, all capable of measuring values in the impact direction.
