                  (a)
               
               
                  A Child Restraint System designed for children up to 15 months of age shall be rearward facing and accommodate at least a child with a stature of 83 cm;
               
            
                  (b)
               
               
                  A forward facing Child Restraint System shall not be designed to accommodate a stature below 71 cm;
               
            
                  (c)
               
               
                  A convertible seat in its rearward facing configuration shall be able to accommodate a child with a stature up to 83 cm. This shall not preclude a child stature greater than 83 cm.
               
            The use of rearward facing Child Restraint System may be applied to any age of child.
      6.2.   Configuration of the Child Restraint System
      6.2.1.   The configuration of the Child Restraint System shall be such that:
      
                  6.2.1.1.
               
               
                  The restraint of the child shall give the required protection in any position specified for the Child Restraint System;
                  For "Special Needs Restraints" the primary means of restraint shall give the required protection in any intended position of the Child Restraint System without the use of the additional restraining devices which may be present;
               
            
                  6.2.1.2.
               
               
                  The Child Restraint System shall be such that the child may be easily and readily restrained or removed. In the case of a Child Restraint System in which the child is restrained by means of a harness belt or a Y-shaped belt without a retractor each shoulder restraint and lap strap shall be capable of movement relative to each other during the procedure prescribed in paragraph 6.7.1.4. below; in these cases the belt assembly of the Child Restraint System may be designed with two or more connecting parts.
                  For "Special Needs Restraints" it is recognized that the additional restraining devices will restrict the speed by which a child can be restrained and removed. However, the additional devices shall be designed to release quickly so far as possible;
               
            
                  6.2.1.3.
               
               
                  If it is possible to change the inclination of the Child Restraint System, this change in inclination shall not require manual readjustment of any other part of the Child Restraint System. A deliberate hand-action shall be necessary in order to change the inclination of the Child Restraint System;
               
            
                  6.2.1.4.
               
               
                  To prevent submarining, either by impact or through restlessness, a crotch strap shall be required on all forward-facing restraints incorporating an integral harness belt system.
               
            
                  6.2.1.5.
               
               
                  All restraint devices utilizing a "lap strap" must positively guide the "lap strap" to ensure that the loads transmitted by the "lap strap" are transmitted through the pelvis. The assembly shall not subject weak parts of the child’s body (abdomen, crotch, etc.) to excessive stresses. The design shall be such that compression loads shall not be imposed on the crown of the child’s head in the event of a collision;
               
            
                  6.2.1.6.
               
               
                  All straps of the restraint shall be so placed that they cannot cause discomfort to the wearer in normal use or assume a dangerous configuration. The distance between the shoulder-straps in the vicinity of the neck should be at least the width of the neck of the appropriate dummy.
               
            
                  6.2.1.7.
               
               
                  With the crotch strap attached and in its longest position if adjustable, it shall not be possible to adjust the lap strap to lie above the pelvis of both the smallest and largest dummy within the mass groups covered by the approval. For all forward-facing restraints, it shall not be possible to adjust the lap strap to lie above the pelvis of both the smallest and largest dummy within the mass groups covered by the approval.
               
            
                  6.2.1.8.
               
               
                  During the dynamic test, as prescribed in paragraph 7.1.3., the lap belt shall not pass fully beyond the pelvic structure of the dummy during the period prior to maximum horizontal head excursion. An assessment shall be carried out using high speed video imaging.
               
            6.2.2.   The Child Restraint System shall be designed and installed so as to:
      
                  6.2.2.1.
               
               
                  Not exhibit sharp edges or protrusions liable to cause damage to vehicle-seat covers or to occupant's clothing;
               
            
                  6.2.2.2.
               
               
                  To ensure that its rigid parts do not, at any point, where they are in contact with straps, exhibit sharp edges capable of abrading the straps.
               
            6.2.3.   It shall not be possible to remove or detach without the use of specific tools, any components not designed to be removable or detachable. Any components that are designed to be removable for maintenance or adjustment purpose shall be so designed as to avoid any risk of incorrect assembly and use, as the assembly and disassembly processes shall be explained in detail in the restraint user guides. Any harness belt shall be capable of its full range of adjustment without disassembly.
      6.2.4.   "Special Needs Restraints" may have additional restraining devices; these shall be designed to avoid any risk of incorrect assembly, and shall be designed so that their means of release and mode of operation is immediately obvious to any rescuer in an emergency.
      6.2.5.   A Child Restraint System may be designed for use in any range of size specified by the manufacturer provided that it satisfies the requirements laid down in this Regulation.
      6.2.6.   Child Restraint Systems incorporating inflatable elements shall be so designed that the conditions of use (pressure, temperature, humidity) have no influence on their ability to comply with the requirements of this Regulation.
      6.3.   Child Restraint System specifications
      6.3.1   Material
      6.3.1.1.   The Child Restraint System manufacturer shall declare in writing that the toxicity of materials used in the manufacture of restraint systems and accessible to the restrained child is in conformity with the relevant parts of EN 71-3:1994/A1:2000/AC.

            6.6.5.   Resistance to temperature
      6.6.5.1.   Buckle assemblies, retractors, adjusters and lock-off devices that are liable to be affected by temperature, shall be subject to the temperature test specified in paragraph 7.2.7. below.
      6.6.5.2.   After the temperature test as prescribed in paragraph 7.2.7.1. below, no signs of deterioration likely to impair the proper functioning of the restraint of the child, shall be visible to the unaided eye of a qualified observer. The dynamic tests should then be performed.
      6.7.   Provisions applicable to individual components of the restraint
      6.7.1.   Buckle
      6.7.1.1.   The buckle shall be so designed as to preclude any possibility of incorrect manipulation. This means, inter/alia, that it shall not be possible for the buckle to be left in a partially closed position; it shall not be possible to exchange the buckle parts inadvertently when the buckle is being locked; the buckle shall only lock when all parts are engaged. Wherever the buckle is in contact with the child, it shall not be narrower than the minimum width of strap as specified in paragraph 6.7.4.1.1. below. This paragraph is not applicable to belt assemblies already approved according to Regulation No. 16 or any equivalent standard in force. In the case of a "Special Needs Restraint" only the buckle on the primary means of restraint need comply with the requirements of paragraphs 6.7.1.2. to 6.7.1.8. inclusive.
      6.7.1.2.   The buckle, even when not under tension, shall remain closed whatever its position. It shall be easy to operate and to grasp. It shall be possible to open it by pressure on a button or on a similar device.
      The surface to which this pressure shall be applied shall have, in the position of actual unlocking and when projected into a plane perpendicular to the button's initial direction of motion:
      
                  (a)
               
               
                  For enclosed devices, an area of not less than 4,5 cm2 with a width of not less than 15 mm;
               
            
                  (b)
               
               
                  For non-enclosed devices, an area of 2,5 cm2 and a width of not less than 10 mm. The width shall be the smaller of the two dimensions forming the prescribed area and shall be measured rectangular to the direction of movement of the release button.
               
            6.7.1.3.   The buckle release area shall be coloured red. No other part of the buckle shall be of this colour.
      6.7.1.4.   It shall be possible to release the child from the restraint by a single operation on a single buckle. It is allowed to remove the child together with devices such as infant carrier/carry-cot/carry-cot restraints if the Child Restraint System can be released by operation of a maximum of two release buttons.
      6.7.1.4.1.   Shoulder strap positioner
      If a shoulder strap positioner is provided, it shall be designed so as to prevent incorrect manipulation. It shall not be possible to use the device in a manner which would cause the shoulder straps to twist. It shall be possible to fasten the device in no more than one action. The force required to fasten the device shall not exceed 15 N.
      6.7.1.4.2.   The shoulder strap positioner shall be easy to operate and to grasp. It shall be possible to open it in one simple action, but it shall be difficult for the child occupant to manipulate the release mechanism. The force required to release the device shall not exceed 15 N.
      6.7.1.4.3.   The shoulder strap positioner shall not exceed 60 mm in height.
      6.7.1.5.   Opening of the buckle shall enable the child to be removed independently of the "chair", "chair support" or "impact shield", if fitted, and if the device includes a crotch strap the crotch strap shall be released by operation of the same buckle.
      6.7.1.6.   The buckle shall be capable of withstanding the temperature test operation requirements given in paragraph 7.2.7. below and repeated operation, and shall, before the dynamic test prescribed in paragraph 7.1.3. below undergo a test comprising 5 000 ± 5 opening and closing cycles under normal conditions for use.
      6.7.1.7.   The buckle shall be subjected to the following tests of opening:
      6.7.1.7.1.   Test under load
      6.7.1.7.1.1.   A Child Restraint System having already undergone the dynamic test prescribed in paragraph 7.1.3. below shall be used for this test.
      6.7.1.7.1.2.   The force required to open the buckle in the test prescribed in paragraph 7.2.1.1. below shall not exceed 80 N.
      6.7.1.7.2.   No-load test
      6.7.1.7.2.1.   A buckle which has not previously been subjected to a load shall be used for this test. The force needed to open the buckle when it is not under load shall be in the range of 40–80 N in the tests prescribed in paragraph 7.2.1.2. below
      6.7.1.8.   Strength
      6.7.1.8.1.   During the test in accordance with paragraph 7.2.1.3.2. below no part of the buckle or the adjacent straps or adjusters shall break or be detached.
      6.7.1.8.2.   Depending of the mass limit declared by the manufacturer, a harness buckle shall withstand:
      
                  6.7.1.8.2.1.
               
               
                  4 kN, if the mass limit is less or equal to 13 kg;
               
            
                  6.7.1.8.2.2.
               
               
                  10 kN, if the mass limit is greater than 13 kg.
               
            6.7.1.8.3.   The Type Approval Authority may dispense with the buckle strength test if information already available renders the test superfluous.
      6.7.2.   Adjusting device
      6.7.2.1.   The range of adjustment shall be sufficient to permit correct adjustment of the Child Restraint System with all size for which the device is intended and to permit satisfactory installation in all i-Size compatible vehicles.
      6.7.2.2.   All adjusting devices shall be of the "quick adjuster" type.
      6.7.2.3.   Devices of the "quick adjuster" type shall be easy to reach when the Child Restraint System is correctly installed and the child or dummy is in position.
      6.7.2.4.   A device of the "quick adjuster" type shall be easily adjustable to the child's physique. In particular, in a test performed in accordance with paragraph 7.2.2.1. below, the force required to operate a manual adjusting device shall not exceed 50 N.
      6.7.2.5.   Two samples of the Child Restraint System adjusting devices shall be tested as prescribed by the temperature test operation requirements given in paragraph 7.2.7.1. and paragraph 7.2.3. below.
      6.7.2.5.1.   The amount of strap slip shall not exceed 25 mm for one adjusting device or 40 mm for all adjusting devices.
      6.7.2.6.   The device shall not break or become detached when tested as prescribed in paragraph 7.2.2.1. below.
      6.7.2.7.   An adjuster mounted directly on the Child Restraint System shall be capable of withstanding repeated operation and shall, before the dynamic test prescribed in paragraph 7.1.3. undergo a test comprising 5 000 ± 5 cycles as specified in paragraph 7.2.3.
      6.7.3.   Retractors
      6.7.3.1.   Automatically-locking retractors
      6.7.3.1.1.   The strap equipped with an automatically-locking retractor shall not unwind by more than 30 mm between locking positions of the retractor. After a rearward movement of the wearer the strap shall either remain in its initial position or return to that position automatically on subsequent forward movement of the wearer.
      6.7.3.1.2.   If the retractor is part of a lap belt, the retracting force of the strap shall be not less than 7 N as measured in the free length between the dummy and the retractor as prescribed in paragraph 7.2.4.1. below. If the retractor is part of a chest restraint, the retracting force of the strap shall be not less than 2 N or more than 7 N as similarly measured. If the strap passes through a guide or pulley, the retracting force shall be measured in the free length between the dummy and the guide or pulley.

      The unoccupied ISOFIX Child Restraint System shall be attached to the ISOFIX anchorage system.
      Securing the ISOFIX attachments to the ISOFIX lower anchorages shall be permitted to draw the unoccupied Child Restraint System towards those anchorages.
      An additional force of 135 +/– 15N shall be applied in a plane parallel to the surface of the test seat cushion. The force shall be applied along the centre line of the Child Restraint System and at a height no more than 100 mm above the cushion.
      If present, the top tether shall be adjusted to achieve a tension load of 50 +/– 5N. Alternatively, and if present, the support-leg shall be adjusted according to the child restraint system manufacturer's instructions.
      The Child Restraint System centre line shall be aligned with the centre line of the test bench.
      The dummy shall be placed in the Child Restraint System separate from the seat-back of the chair by a flexible spacer. The spacer shall be 2,5 cm thick and 6 cm wide. It shall have length equal to the shoulder height less the thigh height, both in the sitting position and relevant to the dummy size being tested. The resulting height of the spacer is listed in the table below for the different dummy sizes. The board should follow as closely as possible the curvature of the chair and its lower end should be at the height of the dummy's hip joint.

                  For lateral impact, positive measures shall be taken to ensure the stability of the dummy is maintained until t0 and this shall be confirmed using video analysis. Any means used to stabilise the dummy before t0 shall not influence the dummy kinematics after t0.
               
            
                   
               
               
                  Because the foam of the test bench seat cushion will compress after installation of the Child Restraint System, the dynamic test shall be conducted no more than 10 minutes after installation.
               
            
                   
               
               
                  To allow the test bench seat cushion to recover, the minimum period between two tests using the same test bench seat cushion shall be 20 minutes.

            Where the Child Restraint System requires substantial modification for different sizes (e.g., convertible Child Restraint System) or if the size range cover more than 3 size ranges a relevant intermediate dummy(ies) shall be tested in addition to the dummy(ies) defined above.
      7.1.3.6.1.   If the Child Restraint System is designed for two or more children, one test shall be carried out with the heaviest dummies occupying all seating positions. A second test with the lightest and the heaviest dummies specified above shall be carried out. The tests shall be conducted using the test bench as shown in Annex 6, Appendix 3, Figure 3. The laboratory conducting the tests may, if it deems it advisable, add a third test with any combination of dummies or empty seat positions.
      7.1.3.6.2.   If the i-Size Child Restraint System uses a top tether, one test shall be carried out with the smallest dummy with the shorter distance of the top tether (anchorage point G1). A second test shall be carried out with the heavier dummy with the longer distance of the top tether (anchorage point G2). Adjust the top tether to achieve a tension load of 50 ± 5 N. For side lateral impact the ISOFIX child restraint shall be tested with only the shorter distance of the top tether.
      7.1.3.6.3.   If the i-Size Child Restraint System uses a support-leg, as an anti-rotation device the hereafter mentioned dynamic tests shall be carried out as follows:
      
                  (a)
               
               
                  The tests for frontal impact shall be conducted with the support-leg adjusted to its maximum adjustment compatible with the positioning of the trolley floor pan. The tests for rear impact shall be conducted with the worst case position selected by the Technical Service. During the tests the support-leg shall be supported by the trolley floor pan as described in Annex 6, Appendix 3, Figure 2;
               
            
                  (b)
               
               
                  In the case of support-legs out of the plane of symmetry, the worst case shall be selected by the Technical Service for the test;
               
            
                  (c)
               
               
                  In the case of "Specific vehicle ISOFIX" category, the support-leg shall be adjusted as specified by the Child Restraint System manufacturer;
               
            
                  (d)
               
               
                  The leg length of a support-leg shall be adjustable in such a way that it is able to cover the complete span of floor pan levels that are allowed for in Regulation No. 16, Annex 17 for car seats to be approved for the installation i-Size Child Restraints Systems.
               
            7.1.3.6.4.   The test specified in paragraph 6.6.4.1.6.2. above is a requirement only for the largest dummy for which the child restraint is designed.
      7.2.   Testing of individual components
      7.2.1.   Buckle
      7.2.1.1.   Opening test under load
      7.2.1.1.1.   A child restraint already having been subjected to the dynamic test specified in paragraph 7.1.3. above shall be used for this test.
      7.2.1.1.2.   The child restraint shall be removed from the test trolley or the vehicle without opening the buckle. A tension of 200 ± 2 N shall be applied to the buckle. If the buckle is attached to a rigid part, the force shall be applied reproducing the angle formed between the buckle and that rigid part during the dynamic test.
      7.2.1.1.3.   A load shall be applied at a speed of 400 ± 20 mm/min to the geometric centre of the buckle-release button along a fixed axis running parallel to the initial direction of motion of the button; the geometric centre applies to that part of the surface of the buckle to which the release pressure is to be applied. The buckle shall be secured against a rigid support during the application of the opening force.
      7.2.1.1.4.   The buckle opening force shall be applied, using a dynamometer or similar device in the manner and direction of normal use. The contact end shall be a polished metal hemisphere with radius 2,5 ± 0,1 mm.
      7.2.1.1.5.   The buckle opening force shall be measured and any failure noted.
      7.2.1.2.   Opening test under zero load
      7.2.1.2.1.   A buckle assembly which has not previously been subjected to a load shall be mounted and positioned under a "no load" condition.
      7.2.1.2.2.   The method of measuring the buckle opening force shall be as prescribed in paragraphs 7.2.1.1.3. and 7.2.1.1.4. above.
      7.2.1.2.3.   The buckle opening force shall be measured.
      7.2.1.3.   Strength testing
      7.2.1.3.1.   For the strength test two samples have to be used. All adjusters, except for adjusters mounted directly on a child restraint are included in the test.
      7.2.1.3.2.   Annex 16 shows a typical device for a buckle strength test. The buckle is placed on the upper round plate (A) within the relief. All adjacent straps have a length of at least 250 mm and are arranged hanging down from the upper plate respective to their position at the buckle. The free strap ends are then wound round the lower round plate (B) until they come out at the plate's inner opening. All straps have to be vertical between A and B. The round clamping plate (C) is then lightly clamped against the lower face of (B), still allowing a certain strap movement between them. With a small force at the tensile machine the straps are tensioned and pulled between (B) and (C) until all straps are loaded respective to their arrangement. The buckle shall stay free from plate (A) or any parts at (A) during this operation and the test itself. (B) and (C) are then clamped firmly together and the tensile force is increased at a traverse speed of 100 ± 20 mm/min until the required values are reached.
      7.2.2.   Adjusting device
      7.2.2.1.   Ease of adjustment
      7.2.2.1.1.   When testing a manual adjusting device, the strap shall be drawn steadily through the adjusting device, having regard for the normal conditions of use, at a rate of 100 ± 20 mm/min and the maximum force measured to the nearest integer value of N after the first 25 ± 5 mm of strap movement.
      7.2.2.1.2.   The test shall be carried out in both directions of strap travel through the device, the strap being subjected to the full travel cycle 10 times prior to the measurement.
      7.2.3.   Microslip test (see Annex 5, Figure 3)
      7.2.3.1.   The components or devices to be subjected to the microslip test shall be kept for a minimum of 24 hours before testing in an atmosphere having a temperature of 20 °C ± 5 °C and a relative humidity of 65 ± 5 per cent. The test shall be carried out at a temperature between 15 °C and 30 °C.
      7.2.3.2.   The free end of the strap shall be arranged in the same configuration as when the device is in use in the vehicle, and shall not be attached to any other part.
      7.2.3.3.   The adjusting device shall be placed on a vertical piece of strap one end of which bears a load of 50 ± 0,5 N (guided in a manner which prevents the load from swinging and the strap from twisting). The free end of the strap from the adjusting device shall be mounted vertically upwards or downwards as it is in the vehicle. The other end shall pass over a deflector roller with its horizontal axis parallel to the plane of the section of strap supporting the load, the section passing over the roller being horizontal.
      7.2.3.4.   The device being tested shall be arranged in such a way that its centre, in the highest position to which it can be raised, is 300 ± 5 mm from a support table, and the load of 50 N shall be 100 ± 5 mm from that support table.
      7.2.3.5.   20 ± 2 pre-test cycles shall then be completed and 1 000 ± 5 cycles shall then be completed at a frequency of 30 ± 10 cycles per minute, the total amplitude being 300 ± 20 mm or as specified in paragraph 7.2.5.2.6.2. above. The 50 N load shall be applied only during the time corresponding to a shift of 100 ± 20 mm for each half period. Microslip shall be measured from the position at the end of the 20 pre-test cycles.
      7.2.4.   Retractor
      7.2.4.1.   Retracting force
      7.2.4.1.1.   The retracting forces shall be measured with the safety belt assembly, fitted to a dummy as for the dynamic test prescribed in paragraph 7.1.3. above. The strap tension shall be measured at the point of contact with (but just clear of) the dummy while the strap is being retracted at the approximate rate of 0,6 m/min.
      7.2.4.2.   Durability of retractor mechanism
      7.2.4.2.1.   The strap shall be withdrawn and allowed to retract for the required number of cycles at a rate of not more than 30 cycles per minute. In the case of emergency-locking retractors, a jolt to lock the retractor shall be introduced at each fifth cycle. The jolts occur in equal numbers at each of five different extractions, namely, 90, 80, 75, 70 and 65 per cent of the total length of the strap on the retractor. However, where the length of the strap exceeds 900 mm the above percentage shall be related to the final 900 mm of strap which can be withdrawn from the retractor.
      7.2.4.3.   Locking of emergency-locking retractors
      7.2.4.3.1.   The retractor shall be tested once for locking, when the strap has been unwound to its full length less 300 ± 3 mm.
      7.2.4.3.2.   In the case of a retractor actuated by strap movement, the extraction shall be in the direction in which it normally occurs when the retractor is installed in a vehicle.
      7.2.4.3.3.   When retractors are being tested for sensitivity to vehicle accelerations, they shall be tested at the above extraction length in both directions along two mutually perpendicular axes which are horizontal if the retractors are to be installed in a vehicle as specified by the child restraint manufacturer. When this position is not specified, the testing authority shall consult the child restraint manufacturer. One of these test directions shall be chosen by the Technical Service conducting the approval tests to give the most adverse conditions with respect to actuation of the locking mechanism.
      7.2.4.3.4.   The design of the apparatus used shall be such that the required acceleration is given at an average rate of increase of acceleration of at least 25 g/s (8).
      7.2.4.3.5.   For testing compliance with the requirements of paragraphs 6.7.3.2.1.3. and 6.7.3.2.1.4. above the retractor shall be mounted on a horizontal table and the table tilted at a speed not exceeding 2° per second until locking has occurred. The test shall be repeated with tilting in other directions to ensure that the requirements are fulfilled.
      7.2.4.4.   Corrosion testing
      7.2.4.4.1.   The corrosion testing shall be carried out as paragraph 7.1.1. above.
      7.2.4.5.   Dust resistance testing
      7.2.4.5.1.   The retractor shall be positioned in a test chamber as described in Annex 3 to this Regulation. It shall be mounted in an orientation similar to that in which it is mounted in the vehicle. The test chamber shall contain dust as specified in paragraph 7.2.4.5.2. below. A length of 500 mm of the strap shall be extracted from the retractor and kept extracted, except that it shall be subjected to 10 complete cycles of retraction and withdrawal within one or two minutes after each agitation of the dust. For a period of five hours, the dust shall be agitated every 20 minutes for five seconds by compressed air free of oil and moisture at a gauge pressure of 5,5 ± 0,5 bars entering through an orifice 1,5 ± 0,1 mm in diameter.
      7.2.4.5.2.   The dust used in the test described in paragraph 7.2.4.5.1. above shall consist of about 1 kg of dry quartz. The particle size distribution shall be as follows:
      
                  (a)
               
               
                  Passing 150 μm aperture, 104 μm wire diameter: 99 to 100 per cent;
               
            
                  (b)
               
               
                  Passing 105 μm aperture, 64 μm wire diameter: 76 to 86 per cent;
               
            
                  (c)
               
               
                  Passing 75 μm aperture, 52 μm wire diameter: 60 to 70 per cent.
               
            7.2.5.   Static test for straps
      7.2.5.1.   Strap strength test
      7.2.5.1.1.   Each test shall be carried out on two new samples of strap, conditioned as specified in paragraph 6.7.4. of this Regulation
      7.2.5.1.2.   Each strap shall be gripped between the clamps of a tensile strength-testing machine. The clamps shall be so designed as to avoid breakage of the strap at or near them. The speed of traverse shall be 100 ± 20 mm/min. The free length of the specimen between the clamps of the machine at the start of the test shall be 200 mm ± 40 mm.
      7.2.5.1.2.1.   The tension shall be increased until the strap breaks and the breaking load noted.
      7.2.5.1.3.   If the strap slips or breaks at or within 10 mm of either of the clamps, the test shall be invalid and a new test shall be carried out on another specimen.
      7.2.5.2.   Samples out from straps, as referred to in paragraph 3.2.3. of this Regulation, shall be conditioned as follows:
      7.2.5.2.1.   Room conditioning
      7.2.5.2.1.1.   The strap shall be kept for 24 ± 1 hours in an atmosphere having a temperature of 23 °C ± 5 °C and a relative humidity of 50 ± 10 per cent.

      7.2.5.2.6.2.   The table below sets out the general conditions for each test:
      
         Table 8
      
      
                   
               
               
                  Load (N)
               
               
                  Cycles per minute
               
               
                  Cycles (No.)
               
            
                  Type 1 procedure
               
               
                  10 ± 0,1
               
               
                  30 ± 10
               
               
                  1 000 ± 5
               
            
                  Type 2 procedure
               
               
                  5 ± 0,05
               
               
                  30 ± 10
               
               
                  5 000 ± 5
               
            Where there is insufficient strap to test over 300 mm of shift, the test may be applied over a shorter length subject to a minimum of 100 mm.
      7.2.5.2.6.3.   Particular test conditions
      7.2.5.2.6.3.1.   Type 1 procedure: For cases where the strap slides through the quick adjusting device. The 10 N load shall be vertically and permanently applied on one of the straps. The other strap, set horizontally, shall be attached to a device, giving the webbing a back and forth motion. The adjusting device shall be so placed that the horizontal strap of the webbing remains under tension (see Annex 5, Figure 1).
      7.2.5.2.6.3.2.   Type 2 procedure: For cases where the strap changes direction in passing through a rigid part. During this test, the angles of both webbing straps shall be as shown in Annex 5, Figure 2. The 5 N load shall be permanently applied. For cases where the strap changes direction more than once in passing through a rigid part, the load of 5 N may be increased so as to achieve the prescribed 300 mm of strap movement through that rigid part.
      7.2.6.   Conditioning test for adjusters mounted directly on a child restraint
      Install the largest dummy for which the restraint is intended, as if for the dynamic test, including the standard slack as specified in paragraph 7.1.3.5. above. Mark a reference line on the webbing where the free end of the webbing enters the adjuster.
      Remove the dummy and place the restraint in the conditioning rig shown in Figure 1, Annex 16.
      The webbing shall be cycled for a total distance of not less than 150 mm through the adjuster. This movement shall be such that at least 100 mm of webbing on the side of the reference line towards the free end of the webbing and the remainder of the moving distance (approx. 50 mm) on the integral harness side of the reference line moves through the adjuster.
      If the length of webbing from the reference line to the free end of the webbing is insufficient for the movement described above, the 150 mm of movement through the adjuster shall be from the fully extended harness position.
      The frequency of cycling shall be 10 ± 1 cycles/minute, with a velocity on "B" of 150 ± 10 mm/sec.
      7.2.7.   Temperature test
      7.2.7.1.   The components specified in paragraph 6.6.5.1. above shall be exposed to an environment over a water surface within a closed space, the environment having a temperature of not less than 80 °C, for a continuous period of not less than 24 hours and then cooled in an environment having a temperature not exceeding 23 °C. The cooling period shall immediately be followed by three consecutive 24 hour cycles with each cycle comprising the following consecutive sequences:
      
                  (a)
               
               
                  An environment having a temperature of not less than 100 °C shall be maintained for a continuous period of 6 hours and this environment shall be attained within 80 minutes of commencement of the cycle; then
               
            
                  (b)
               
               
                  An environment having a temperature of not more than 0 °C shall be maintained for a continuous period of 6 hours and this environment shall be attained within 90 minutes; then
               
            
                  (c)
               
               
                  An environment having a temperature of not more than 23 °C shall be maintained during the remainder of the 24 hour cycle.
               
            7.2.8.   The complete seat, or the component fitted with ISOFIX attachments (e.g. ISOFIX base) if it has a release button, is attached rigidly to a test rig in such a way that ISOFIX connectors are vertically aligned as shown in Figure 3. A 6 mm diameter bar, 350 mm long, shall be attached to the ISOFIX connectors. A mass of 5 kg shall be attached to the extremities of the bar.
      7.2.8.1.   An opening force shall be applied to the release button or handle along a fixed axis running parallel to the initial direction of motion of the button/handle; the geometric centre applies to that part of the surface of the ISOFIX attachment to which the release pressure is to be applied.
      7.2.8.2.   The ISOFIX attachment opening force shall be applied using a dynamometer or similar device in the normal manner and direction as indicated in the manufacturers user manual. The contact end shall be a polished metal hemisphere with radius 2,5 ± 0,1 mm for a release button or a polished metal hook with a radius of 25 mm.
      7.2.8.3.   If the design of the child restraint prevents the application of the procedure described in paragraphs 7.2.8.1. and 7.2.8.2., an alternative method may be applied with the agreement of the Technical Service carrying out the test.
      7.2.8.4.   The ISOFIX attachment opening force to be measured shall be that needed to disengage the first connector.
      7.2.8.5.   The test shall be carried out on a new seat, and repeated on a seat that has been subjected to the cycling procedure specified in paragraph 6.7.5.1.
      
         
      7.3.   Certification of test bench cushion.
      7.3.1.   The test bench seat cushion shall be certified when new to establish initial values for impact penetration and peak deceleration, and then after every 50 dynamic tests or at least every month, whichever is the sooner, or before each test if the test rig is used frequently.
      7.3.2.   The certification and measuring procedures shall correspond to those specified in the latest version of ISO 6487; the measuring equipment shall correspond to the specification of a data channel with a channel filter class (CFC) 60.
      Using the test device defined in Annex 14 to this Regulation, conducts three tests, 150 ± 5 mm from the front edge of the cushion on the centre line and at 150 ± 5 mm in each direction from the centre line.
      Place the device vertically on a flat rigid surface. Lower the impact mass until it contacts the surface and set the penetration marker to the zero position. Place the device vertically above the test point, raise the mass 500 ± 5 mm and allow it to fall freely to make impact on the test bench seat cushion surface. Record the penetration and the deceleration curve.
      7.3.3.   The peak values recorded shall not deviate by more than 15 per cent from the initial values.
      7.4.   Registration of dynamic behaviour

                  Every modification of a Child Restraint System shall be notified to the Type Approval Authority which approved the Child Restraint System. The Type Approval Authority may then either:
                  
                              11.1.1.
                           
                           
                              Consider that the modifications made are unlikely to have an appreciable adverse effect and that in any case the Child Restraint System still complies with the requirements; or
                           
                        
                              11.1.2.
                           
                           
                              Require a further test report from the Technical Service responsible for conducting the tests.

                  If a further test report is required, compare the horizontal head excursion result with the worst case from all results previously recorded:
                  
                              (a)
                           
                           
                              If the excursion is greater, then new production qualification testing must be carried out;
                           
                        
                              (b)
                           
                           
                              If the excursion is less, production qualification tests do not need to be carried out.

                                 The test bench seat cushion is produced out of a square foam block (800 × 575 × 135 mm) in such a way (see Figure 1 of Appendix 1 to this annex) that its shape resembles the shape of the aluminium bottom-plate specified in Figure 2 of Appendix 1 to this annex.
                              
                           
                                 3.1.7.2.
                              
                              
                                 Six holes are drilled in the bottom-plate in order to fasten it to the trolley with bolts. The holes are drilled alongside the longest side of the plate, three on each side, their position being dependent on the construction of the trolley. Six bolts are put through the holes. It is recommended to glue the bolts on the plate with an appropriate adhesive. Afterwards, the bolts are fastened with nuts.
                              
                           
                                 3.1.7.3.
                              
                              
                                 The cover material (1 250 × 1 200 mm, see Figure 3 of Appendix 1 to this annex) is cut across the width in such a way that it is not possible for the material to overlap after covering. There should be a gap of about 100 mm between the edges of the cover material. Therefore the material has to be cut at about 1 200 mm.
                              
                           
                                 3.1.7.4.
                              
                              
                                 The cover material is marked with two lines which run across the width. They are drawn 375 mm from the centreline of the cover material (see Figure 3 of Appendix 1 to this annex).
                              
                           
                                 3.1.7.5.
                              
                              
                                 The test bench seat cushion is placed upside down on the cover material with the aluminium bottom-plate on top.
                              
                           
                                 3.1.7.6.
                              
                              
                                 On both sides the cover material is stretched until the lines drawn on it match the edges of the aluminium bottom-plate. At each bolt position, small incisions are made and the cover material is pulled over the bolts.
                              
                           
                                 3.1.7.7.
                              
                              
                                 At the position of the grooves in the bottom-plate and in the foam, the cover material should be incised.
                              
                           
                                 3.1.7.8.
                              
                              
                                 The cover is glued to the aluminium plate with flexible glue. The nuts have to be removed before gluing.

                                 The flaps on the side are folded onto the plate and are glued as well.

                                 The test bench seat-back cushion is covered in exactly the same way as the test bench seat cushion, only the lines on the cover material
                                 (1 250 × 850 mm) are drawn 333 mm apart from the centreline of the material.

            2.   PANEL PADDING SPECIFICATION
            2.1.   General
            The door panel is padded with 55 mm padding material (Annex 6, Appendix 3, Figure 1), which has to comply with the performance criteria as described in Appendix 3 to this Regulation, paragraph 2.3. realised in a test set up as described in Appendix 3 to this Regulation, paragraph 2.2.
            2.2.   Test procedure for the assessment of panel padding material
            The test set up consists of a simple drop test using a spherical head form. The spherical head form has a diameter of 150 mm and a mass of 6 kg (± 0,1 kg). The impact speed is 4 m/s (± 0,1 m/s). The instrumentation should allow the assessment of the time of first contact between the impactor and the sample as well as the head form acceleration at least in direction of impact (Z-direction).
            The material sample should have the dimensions of 400 × 400 mm. The sample should be impacted in its centre.
            2.3.   Performance criteria for the padding material
            The time of first contact between sample material and head form (t0) is 0 ms.
            The impactor acceleration shall not exceed 58 g.

            Appendix 4
            1.   DOOR PANEL DEFINITION
            The door panel geometry shall be in line with the bench definition.
            Drawing to describe the door will be proposed in line with the NPACS bench.
            2.   PANEL PADDING SPECIFICATION
            2.1.   General
            The impacting surface of the door panel shall be entirely covered with a padding material 55 mm in thickness. The material shall comply with the performance criteria specified in paragraph 2.3. of this appendix when tested in accordance with paragraph 2.2. of this appendix.
            A material combination that has been found to meet these requirements is detailed in paragraph 2.4. of this appendix.
            2.2.   Test procedure for the assessment of panel padding material
            The test set up consists of a simple drop test using a spherical head form. The spherical head form has a diameter of 150 mm and a mass of 6 kg (± 0,1 kg). The impact speed is 4 m/s (± 0,1 m/s). The instrumentation should allow the assessment of the time of first contact between the impactor and the sample as well as the head form acceleration at least in direction of impact (Z-direction).
            The material sample should have the dimensions of 400 × 400 mm. The sample should be impacted in its centre.
            2.3.   Performance criteria for the padding material
            The time of first contact between sample material and head form (t0) is 0 ms.
            The impactor acceleration shall not exceed 58 g.

               2.   DESCRIPTION OF THE DUMMIES
         
                  
                     2.1.
                  
                  
                     The dimensions and masses of the Q0, Q1, Q1,5, Q3, Q6 and Q10 dummies described below are based on the anthropometry of 50th per centile children aged 0, 1, 1,5, 3, 6 and 10,5 years respectively.
                  
               
                  
                     2.2.
                  
                  
                     The dummies consist of a metal and plastic skeleton covered with plastic skinned foam parts to complete body components.
                  
               3.   CONSTRUCTION
         3.1.   Head
         The head is largely made from synthetics. The head cavity is large enough to allow use of several instruments, including linear accelerometers and angular velocity sensors.
         3.2.   Neck
         The neck is flexible and allows shear and bending in all directions. The segmented design allows a realistic rotational behaviour. The neck is equipped with low stretch neck-cord in order to prevent excessive elongation. The neck-cord is also designed to act as a safety cord in case of rubber failure. A six channel load cell can be mounted at the neck-head and neck-torso interface. The Q0, Q1 and Q1,5 cannot accommodate the load cell between neck and torso.
         3.3.   Thorax
         The thorax of the child is represented by a single rib-cage. The deformation can be measured with a string potentiometer in Q1 andQ1.5 and an IR-TRACC sensors in Q3, Q6 and Q10. The shoulders are connected with a flexible joint to the thorax, allowing deformation forwards.
         3.4.   Accelerometers can be mounted on the spine to measure linear accelerations. The Q0 thorax has a simplified layout with an integral foam part for the complete torso.
         3.5.   Abdomen
         The abdomen is foam covered with skin. Biomechanical data from children has been used to determine the required stiffness. The Q0 abdomen has a simplified layout with an integral foam part for the complete torso.
         3.6.   Lumbar spine
         The lumbar spine is a flexible rubber column, which allows shear and bending in all directions. A six channel load cell can be mounted between the lumbar spine and the pelvis, except for the Q0.
         3.7.   Pelvis
         The pelvis is constructed from an iliac-sacrum bone part covered with a plastic flesh outer contour simulation. In the bone part removable hip joints are inserted. An accelerometer array can be mounted in the pelvis. Special hip joints are available that allow to position the dummy in a standing position. The Q0 pelvis has a simplified layout with an integral foam part for the complete torso.
         3.8.   Legs
         The legs are constructed with metal reinforced plastic bones cover with PVC skinned foam parts that represent the upper and lower flesh. The knee joints can be locked in any position. This feature can be used to facilitate positioning the dummy in a standing position. (Note that the dummy does not have the ability to stand without external support.) The Q0 legs have a simplified layout with one integral part per leg with a fixed angle at the knee.
         3.9.   Arms
         The arms are constructed with plastic bones cover with PVC skinned foam parts that represent the upper and lower flesh. The elbow joints can be locked in any position. The Q0 arms have a simplified layout with one integral part per arm with a fixed angle at the elbow.

                        Notes:
                     
                     MH means harder configuration (the least good results obtained in approval or extension of approval)
                     LH signifies a less hard configuration.
                     This dual sampling plan functions as follows:
                     
                                  
                              
                              
                                 For a normal control, if the first sample does not contain any defective units the batch is accepted without testing a second sample. If it contains two defective units the batch is rejected. Finally, if it contains one defective unit a second sample is extracted and it is the cumulative number, which shall satisfy the condition of column 5 of the table above.
                              
                           
                                  
                              
                              
                                 There is a change from normal control to strengthened control if, out of 5 consecutive batches, two are rejected. Normal control is resumed if 5 consecutive batches are accepted.
                              
                           
                                  
                              
                              
                                 If any batch is rejected, the production is considered to be non-conforming and the batch shall not be released.
                              
                           
                                  
                              
                              
                                 If two consecutive batches subjected to the strengthened control are rejected, the provisions of paragraph 13. of this Regulation are applied.

                     The control of Child Restraint Systems conformity is undertaken starting with the batch manufactured after the first batch which was subjected to production qualification.

                                 If both (the first and the second) Child Restraint Systems do not meet the requirements, the production does not conform and Child Restraint Systems that are likely to present the same failure shall be withdrawn and necessary steps shall be taken to re-establish the conformity of the production.
                              
                           
                                  
                              
                              
                                 Strengthened control will replace normal control if, out of 10 000 Child Restraint Systems manufactured consecutively, the production has to be withdrawn twice.
                              
                           
                                  
                              
                              
                                 Normal control is resumed if 10 000 Child Restraint Systems manufactured consecutively are considered to conform.
                              
                           
                                  
                              
                              
                                 If production subjected to the strengthened control has been withdrawn on two consecutive occasions, the provisions of paragraph 13. of this Regulation are applied.

                     The test results described in paragraph 2.2.2.4. above shall not exceed L, where L is the limit value prescribed for each approval test.
                  
               2.3.   For "Specific vehicle ISOFIX" devices according to paragraph 2.1.2.4.1. above, the Child Restraint System manufacturer may choose Conformity of Production procedures according to either paragraph 2.2. above, on a test bench, or paragraphs 2.3.1. and 2.3.2. below, in a vehicle body shell.
         2.3.1.   For "Specific vehicle ISOFIX" devices, the following test frequencies shall apply once every eight weeks:
         
                      
                  
                  
                     At each test all requirements according to paragraphs 6.6.4. and 6.7.1.7.1. of this Regulation shall be fulfilled. If all tests during one year show satisfactory results, the manufacturer may, after agreement with the Type Approval Authority, reduce the frequencies as follows: once every 16 weeks.
                  
               
                      
                  
                  
                     However, a minimum frequency of one test per year shall be permitted where annual production is 1 000 Child Restraint Systems or less.
                  
               2.3.2.   Where a test sample fails a particular test to which it has been subjected, a further test to the same requirement shall be carried out on at least three other samples. In the case of dynamic tests if one of the latter fails, the production is considered to be non-conforming and the frequency shall be raised to the higher one if the lower one was used according to paragraph 2.3. above and necessary steps shall be taken to re-establish the conformity of the production.
         2.4.   When production is found to be non-conforming according to paragraphs 2.2.1.4., 2.2.2.4. or 2.3.2. above, the holder of the approval or his duly accredited representative shall:
         
                     2.4.1.
                  
                  
                     Notify the Type Approval Authority which has granted type approval indicating what steps have been taken to re-establish the conformity of production.
                  
               2.5.   The manufacturer shall advise the Type Approval Authority on a quarterly basis, the volume of products produced against each approval number, providing a means of identifying which products correspond to that approval number.

            DETERMINATION OF PERFORMANCE CRITERIA
         
         1.   HEAD PERFORMANCE CRITERION (HPC)
         
                  
                     1.1.
                  
                  
                     This criterion is considered to be satisfied when, during the test, there is no contact between the head and any vehicle component.
                  
               
                  
                     1.2.
                  
                  
                     If that is not the case, a calculation of the value of HPC is made, on the basis of the acceleration (a) (1), by the following expression:
                     
                        
                     In which:
                     
                                 1.2.1.
                              
                              
                                 The term "a" is the resultant acceleration is measured in units of gravity, g (1 g = 9,81 m/s2);
                              
                           
                                 1.2.2.
                              
                              
                                 If the beginning of the head contact can be determined satisfactorily, t1 and t2 are the two time instants, expressed in seconds, defining an interval between the beginning of the head contact and the end of the recording for which the value of HPC is maximum;
                              
                           
                                 1.2.3.
                              
                              
                                 If the beginning of the head contact cannot be determined, t1 and t2 are the two time instants, expressed in seconds, defining a time interval between the beginning and the end of the recording for which the value of HPC is maximum;
                              
                           
                                 1.2.4.
                              
                              
                                 Values of HPC for which the time interval (t1 - t2) is greater than 36 ms are ignored for the purposes of calculating the maximum value.
                              
                           
               
                  
                     1.3.
                  
                  
                     The value of the resultant head acceleration during forward impact which is exceeded for 3 ms cumulatively is calculated from the resultant head acceleration.
                  
               
            (1)  The acceleration (a) referring to the centre of gravity is calculated from the triaxial components of the acceleration measured with a CFC of 1 000.
