               6.2.2.5.
            
            
               The force required to open the buckle in the test as prescribed in paragraph 7.8 below shall not exceed 6 daN.
            
         
               6.2.2.6.
            
            
               The buckle shall be tested for strength as prescribed in paragraphs 7.5.1 and, where appropriate, 7.5.5. It must not break, be seriously distorted or become detached under the tension set up by the prescribed load.
            
         
               6.2.2.7.
            
            
               In the case of buckles which incorporate a component common to two assemblies, the strength and release tests of paragraphs 7.7 and 7.8 shall also be carried out with the part of the buckle pertaining to one assembly being engaged in the mating part pertaining to the other, if it is possible for the buckle to be so assembled in use.
            
         6.2.3.   Belt adjusting device
   
               6.2.3.1.
            
            
               The belt after being put on by the wearer, shall either adjust automatically to fit him or be such that the manually adjusting device shall be readily accessible to the seated wearer and shall be convenient and easy to use. It shall also allow the belt to be tightened with one hand to suit the wearer's body size and the position of the vehicle seat.
            
         
               6.2.3.2.
            
            
               Two samples of each belt adjusting device shall be tested in accordance with the requirements of paragraph 7.3. The strap slip shall not exceed 25 mm for each sample of adjusting device and the sum of shifts for all the adjusting devices shall not exceed 40 mm.
            
         
               6.2.3.3.
            
            
               All the adjustment devices shall be tested for strength as prescribed in paragraph 7.5.1. They must not break or become detached under the tension set up by the prescribed load.

         6.2.4.   Attachments and belt adjustment devices for height
   The attachments shall be tested for strength as prescribed in paragraphs 7.5.1 and 7.5.2. The actual belt adjustment devices for height shall be tested for strength as prescribed in paragraph 7.5.2 of this Regulation where they have not been tested on the vehicle in application of Regulation No 14 (in its last version of amendments) relative to anchorages of safety-belts. These parts must not break or become detached under the tension set up by the prescribed load.
   6.2.5.   Retractors
   Retractors shall be subjected to tests and shall fulfil the requirements specified below, including the tests for strength prescribed in paragraphs 7.5.1 and 7.5.2. (These requirements are such that they exclude non-locking retractors.)
   6.2.5.1.   Manually unlocking retractors
   
   
               6.2.5.1.1.
            
            
               The strap of a safety-belt assembly equipped with a manually unlocking retractor shall not move more than 25 mm between locking positions of the reactor.
            
         
               6.2.5.1.2.
            
            
               The strap of a safety-belt assembly shall extract from a manually unlocking retractor within 6 mm of its maximum length when a tension of not less than 1,4 daN and not more than2,2 daN is applied to the strap in the normal direction of pull.
            
         
               6.2.5.1.3.
            
            
               The strap shall be withdrawn from the retractor, and allowed to retract repeatedly by the method described in paragraph 7.6.1 until 5 000 cycles have been completed. The retractor shall then be subjected to the corrosion test given in paragraph 7.2 and to the dust test given in paragraph 7.6.3. It shall then satisfactorily complete a further 5 000 cycles of withdrawal and retraction. After the above tests, the retractor shall operate correctly and still meet the requirements of paragraphs 6.2.5.1.1 and 6.2.5.1.2 above.
            
         6.2.5.2.   Automatically locking retractors
   
   
               6.2.5.2.1.
            
            
               The strap of a safety-belt assembly equipped with an automatically locking retractor shall not move more than 30 mm between locking positions of the retractor. After a rearward movement of the wearer, the belt must either remain at its initial position or return to that position automatically on subsequent forward movements of the wearer.
            
         
               6.2.5.2.2.
            
            
               If the retractor is part of a lap belt, the retracting force of the strap shall be not less than 0,7 daN when measured in the free length between the dummy and the retractor in accordance with paragraph 7.6.4.
               If the retractor is part of an upper torso restraint, the retracting force of the strap shall be not less than 0,1 daN and not more than 0,7 daN when similarly measured.
            
         
               6.2.5.2.3.
            
            
               The strap shall be withdrawn from the retractor and allowed to retract repeatedly by the method described in paragraph 7.6.1 until 5 000 cycles have been completed. The retractor shall then be subjected to the corrosion test given in paragraph 7.2 and after that to the dust test given in paragraph 7.6.3. It shall then satisfactorily complete a further 5 000 cycles of withdrawal and retraction. After the above tests the retractor shall operate correctly and still meet the requirements of paragraphs 6.2.5.2.1 and 6.2.5.2.2 above.
            
         6.2.5.3.   Emergency locking retractors
   
   
               6.2.5.3.1.
            
            
               An emergency locking retractor, when tested in accordance with paragraph 7.6.2, shall satisfy the conditions below. In the case of a single sensitivity, according to paragraph 2.14.4.1, only the specifications regarding deceleration of the vehicle are valid.
            
         
               6.2.5.3.1.1.
            
            
               The locking must have occurred when the deceleration of the vehicle reaches 0,45 g (5) in the case of type 4 or 0,85 g in the case of type 4N retractors.
            
         
               6.2.5.3.1.2.
            
            
               It must not lock for values of acceleration of the strap measured in the direction of the extraction of the strap of less than 0,8 g in the case of type 4 or less than 1,0 g in the case of type 4N retractors.
            
         
               6.2.5.3.1.3.
            
            
               It must not lock when its sensing device is tilted 12o or less in any direction from the installation position specified by its manufacturer.
            
         
               6.2.5.3.1.4.
            
            
               It shall lock when its sensing device is tilted by more than 27o in the case of type 4 or 40o in the case of type 4N retractors in any direction from the installation position specified by its manufacturer.
            
         
               6.2.5.3.1.5.
            
            
               In cases where the operation of a retractor depends on an external signal or power source, the design shall ensure that the retractor locks automatically upon failure or interruption of that signal or power source. However, this requirement need not be met in the case of a retractor with multiple sensitivities, provided only one sensitivity is dependent on an external signal or power source and the failure of the signal or power source is indicated to the driver by optical and/or acoustical means.
            
         
               6.2.5.3.2.
            
            
               When tested in accordance with paragraph 7.6.2, an emergency locking retractor with multiple sensitivity, including strap sensitivity, shall comply with the specified requirements and also lock up when strap acceleration measured in the direction of unreeling is not less than 2,0 g.
            
         
               6.2.5.3.3.
            
            
               In the case of the tests mentioned in paragraphs 6.2.5.3.1 and 6.2.5.3.2 above the amount of strap movement which may occur before the retractor locks shall not exceed 50 mm starting at the length given in paragraph 7.6.2.1. In the case of the test mentioned in paragraph 6.2.5.3.1.2 above locking must not occur during the 50 mm of strap movement starting at the length given in paragraph 7.6.2.1.
            
         
               6.2.5.3.4.
            
            
               If the retractor is part of a lap belt, the retracting force of the strap shall be not less than 0,7 daN when measured in the free length between the dummy and the retractor in accordance with paragraph 7.6.4.
               If the retractor is part of an upper torso restraint, the retracting force of the strap shall be not less than 0,1 daN and not more than 0,7 daN when similarly measured, except for a belt equipped with a tension-reducing device, in which case the minimum retracting force may be reduced to 0,05 daN only when such a device is in operation mode. 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.
               If the assembly incorporates a device that upon manual or automatic operation prevents the strap from being completely retracted, such a device shall not be operated when these requirements are assessed.
               If the assembly incorporates a tension-reducing device, the retracting force of the strap described in the above shall be measured with the device in operation mode and non-operation mode when these requirements are assessed before and after durability tests according to paragraph 6.2.5.3.5.
            
         
               6.2.5.3.5.
            
            
               The strap shall be withdrawn from the retractor and allowed to retract repeatedly by the method described in paragraph 7.6.1 until 40 000 cycles have been completed. The retractor shall then be subjected to the corrosion test given in paragraph 7.2 and after that to the dust test prescribed in paragraph 7.6.3. It shall then satisfactorily complete a further 5 000 cycles (making 45 000 in all).
               If the assembly incorporates a tension-reducing device, the above tests shall be conducted on condition that the tension-reducing device is in operation mode and in non-operation mode.
               After the above tests, the retractor shall operate correctly and still meet the requirements of paragraphs 6.2.5.3.1, 6.2.5.3.3 and 6.2.5.3.4 above.
            
         
               6.2.5.4.
            
            
               Retractors must fulfill, after durability test according to paragraph 6.2.5.3.5, and immediately after the retracting force measurement according to paragraph 6.2.5.3.4, all next two specifications:
            
         
               6.2.5.4.1.
            
            
               When retractors except automatically locking retractors are tested according to paragraph 7.6.4.2, the retractors must be able to avoid any slack between torso and belt, and,
            
         
               6.2.5.4.2.
            
            
               When the buckle is unlatched to release the tongue, the retractor alone must be able to retract strap fully.
            
         6.2.6.   Pre-loading device
   
               6.2.6.1.
            
            
               After being submitted to corrosion testing in accordance with paragraph 7.2, the pre-loading device (including the impact sensor connected to the device by the original plugs but without any current passing through them) shall operate normally.
            
         
               6.2.6.2.
            
            
               It shall be verified that inadvertent operation of the device does not involve any risk of bodily injury for wearer.
            
         
               6.2.6.3.
            
            
               In the case of pyrotechnic pre-loading devices:
            
         
               6.2.6.3.1.
            
            
               After being submitted to conditioning in accordance with paragraph 7.9.2, operation of the pre-loading device must not have been activated by temperature and the device shall operate normally.
            
         
               6.2.6.3.2.
            
            
               Precautions shall be taken to prevent the hot gases expelled from igniting adjacent flammable materials.
            
         6.3.   Straps
   6.3.1.   General
   
               6.3.1.1.
            
            
               The characteristics of the straps shall be such as to ensure that their pressure on the wearer's body is distributed as evenly as possible over their width and that they do not twist even under tension. They shall have energy-absorbing and energy-dispersing capacities. The straps shall have finished selvages which shall not become unravelled in use.
            
         
               6.3.1.2.
            
            
               The width of the strap under load of 980 daN shall be not less than 46 mm. This dimension shall be measured during the breaking-strength test prescribed in paragraph 7.4.2 and without stopping the machine.

               The belt assembly or restraint system shall be subjected to a dynamic test in conformity with paragraph 7.7 below.
            
         
               6.4.1.2.
            
            
               The dynamic test shall be performed on two belt assemblies which have not previously been under load, except in the case of belt assemblies forming part of restraint systems when the dynamic test shall be performed on the restraint systems intended for one group of seats which have not previously been under load. The buckles of the belt assemblies to be tested shall have met the requirements of paragraph 6.2.2.4 above. In the case of safety-belts with retractors, the retractor shall have been subjected to the dust resistance test laid down in paragraph 7.6.3; in addition, in the case of safety-belts or restraint systems equipped with a pre-loading device comprising pyrotechnic means, the device shall have been subjected to the conditioning specified in paragraph 7.9.2.
            
         
               6.4.1.2.1.
            
            
               The belts shall have undergone the corrosion test described in paragraph 7.2, after which the buckles shall be subjected to 500 additional opening and closing cycles under normal conditions of use.
            
         
               6.4.1.2.2.
            
            
               Safety-belts with retractors shall have been subjected either to the tests described in paragraph 6.2.5.2 or to those described in paragraph 6.2.5.3. If, however, a retractor has already been subjected to the corrosion test in accordance with the provisions of paragraph 6.4.1.2.1, above, this test need not be repeated.
            
         
               6.4.1.2.3.
            
            
               In the case of a belt intended for use with a belt adjustment device for height, as defined in paragraph 2.9.6 above, the test shall be carried out with the device adjusted in the most unfavourable position(s) chosen by the technical service responsible for testing. However, if the belt adjustment device for height is constituted by the belt anchorage, as approved in accordance with the provisions of Regulation No 14, the technical service responsible for testing may, at its discretion, apply the provisions of paragraph 7.7.1 below.
            
         
               6.4.1.2.4.
            
            
               In the case of safety-belt with a preloading device the minimum displacement specified in paragraph 6.4.1.3.2 below may be reduced by half. For the purpose of this test, the preloading device shall be in operation.
            
         
               6.4.1.2.5.
            
            
               In the case of a safety-belt with tension-reducing device, it shall be subjected to a durability test with such a device in operation mode according to paragraph 6.2.5.3.5 before a dynamic test. The dynamic test shall then be conducted with the tension-reducing device in operation mode.
            
         
               6.4.1.3.
            
            
               During this test, the following requirements shall be met:
            
         
               6.4.1.3.1.
            
            
               No part of the belt assembly or a restraint system affecting the restraint of the occupant shall break and no buckles or locking system or displacement system shall release or unlock; and
            
         
               6.4.1.3.2.
            
            
               the forward displacement of the manikin shall be between 80 and 200 mm at pelvic level in the case of lap belts. In the case of other types of belts, the forward displacement shall be between 80 and 200 mm at pelvic level and between 100 and 300 mm at chest level. In the case of a harness belt, the minimum displacements specified above may be reduced by half. These displacements are the displacements in relation to the measurement points shown in Annex 7, figure 6 to this Regulation.
            
         
               6.4.1.3.3.
            
            
               In the case of a safety-belt intended to be used in an outboard front seating position protected by an airbag in front of it, the displacement of the chest reference point may exceed that specified in paragraph 6.4.1.3.2 above if its speed at this value does not exceed 24 km/h.
            
         
               6.4.1.4.
            
            
               In the case of a restraint system:
            
         
               6.4.1.4.1.
            
            
               The movement of the chest reference point may exceed that specified in paragraph 6.4.1.3.2 above if it can be shown either by calculation or a further test that no part of the torso or the head of the manikin used in the dynamic test would have come into contact with any forward rigid part of the vehicle other than the chest with the steering assembly, if the latter meets the requirements of Regulation No 12 and provided contact does not occur at a speed higher than 24 km/h. For this assessment the seat shall be considered to be in the position specified in paragraph 7.7.1.5 below.
            
         
               6.4.1.4.2.
            
            
               In vehicles where such devices are used, the displacement and locking systems enabling the occupants of all seats to leave the vehicle shall still be operable by hand after the dynamic test.
            
         
               6.4.1.5.
            
            
               By way of derogation, in case of a restraint system, the displacements may be greater than those specified in paragraph 6.4.1.3.2 in the case where the upper anchorage fitted to the seat profits from the derogation provided in Regulation No 14, paragraph 7.4.
            
         6.4.2.   Strength after abrasion conditioning
   
               6.4.2.1.
            
            
               For both samples conditioned in compliance with paragraph 7.4.1.6 below, the breaking strength shall be assessed as prescribed in paragraphs 7.4.2 and 7.5. below. It must be at least equal to 75 per cent of the breaking strength average determined during tests on unabraded straps and not less than the minimum load specified for the item being tested. Difference between breaking strength of the two samples must not exceed 20 per cent of the highest measured breaking strength. For type 1 and type 2 procedures, the breaking strength test shall be carried out on strap samples only (paragraph 7.4.2). For type 3 procedure, the breaking strength test shall be carried out on the strap in combination with the metal component involved (paragraph 7.5).
            
         
               6.4.2.2.
            
            
               The parts of the belt assembly to be subjected to an abrasion procedure are given in the following table and the procedure types which may be appropriate for them are indicated by ‘x’. A new sample shall be used for each procedure.

               The abrasion conditioning will be performed on every device in which the strap is in contact with a rigid part of the belt, with the exception of all adjusting devices where the micro-slip test (7.3) shows that the strap slips by less than half the prescribed value, in which case, the procedure 1 abrasion conditioning (7.4.1.6.4.1) will not be necessary. The setting on the conditioning device will approximately maintain the relative position of strap and contact area.
            
         
               7.4.1.6.2.
            
            
               The samples shall be kept for a minimum of 24 hours in an atmosphere having a temperature of 20 ± 5 oC and relative humidity of 65 ± 5 per cent. The ambient temperature during the abrasion procedure shall be between 15 and 30 oC.
            
         
               7.4.1.6.3.

               Procedure 1: for cases where the strap slides through an adjusting device.
               A vertical steady load of 2,5 daN shall be maintained on one end of the strap — the other end of the strap shall be attached to a device giving the strap a horizontal back and forth motion.
               The adjusting device shall be placed on the horizontal strap so that the strap remains under tension (see Annex 11, Figure 1 to this Regulation).
            
         
               7.4.1.6.4.2
            
            
               Procedure 2: for cases where the strap changes direction in passing through a rigid part.
               During this test, the angles of the straps shall be maintained as shown in Annex 11, Figure 2, to this Regulation.
               The steady load of 0,5 daN shall be maintained during the test.
               For cases where the strap changes direction more than once in passing through a rigid part, the load of 0,5 daN may be increased so as to achieve the prescribed strap movement of 300 mm through that rigid part.
            
         
               7.4.1.6.4.3.
            
            
               Procedure 3: for cases where the strap is fixed to a rigid part by sewing or similar means.
               The total back and forth motion shall be 300 ± 20 mm but the 5 daN load shall only be applied during a shift of 100 ± 20 mm for each half period (see Annex 11, figure 3, to this Regulation).
            
         7.4.2.   Test of breaking strength of strap (static test)
   
               7.4.2.1.
            
            
               The test shall be carried out each time on two new samples of strap, of sufficient length, conditioned in conformity with the provisions of paragraph 7.4.1.
            
         
               7.4.2.2.
            
            
               Each strap shall be gripped between the clamps of a tensile-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 about 100 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.
            
         
               7.4.2.3.
            
            
               When the load reaches 980 daN, the width of the strap shall be measured without stopping the machine.
            
         
               7.4.2.4.
            
            
               The tension shall be increased until the strap breaks, and the breaking load shall be noted.
            
         
               7.4.2.5.
            
            
               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.
            
         7.5.   Test of belt assembly components incorporating rigid parts
   
               7.5.1.
            
            
               The buckle and the adjusting device shall be connected to the tensile-testing apparatus by the parts of the belt assembly to which they are normally attached, and the load shall then build up to 980 daN.
               In the case of harness belts, the buckle shall be connected to the testing apparatus by the straps which are attached to the buckle and the tongue or two tongues located in an approximately symmetrical way to the geometric centre of the buckle. If the buckle, or the adjusting device, is part of the attachment or of the common part of a three-point belt, the buckle or adjusting device shall be tested with the attachment, in conformity with paragraph 7.5.2 below, except in the case of retractors having a pulley or strap guide at the upper belt anchorage, when the load will be 980 daN and the length of strap remaining wound on the reel shall be the length resulting from locking as close as possible to 450 mm from the end of the strap.
            
         
               7.5.2.
            
            
               The attachments and any belt adjustment devices for height shall be tested in the manner indicated in paragraph 7.5.1, but the load shall be 1 470 daN and shall, subject to the provisions of the second sentence of paragraph 7.7.1 below, be applied in the least favourable conditions likely to occur in a vehicle in which the belt is correctly installed. In the case of retractors the test is performed with the strap completely unwound from the reel.
            
         
               7.5.3.
            
            
               Two samples of the complete belt assembly shall be placed in a refrigerated cabinet at - 10o ± 1 oC for two hours. The mating parts of the buckle shall be coupled together manually immediately after being removed from the refrigerated cabinet.
            
         
               7.5.4.
            
            
               Two samples of complete belt assembly shall be placed in a refrigerated cabinet at - 10 oC ± 1 oC for two hours. The rigid items and parts made of plastics under test shall then be laid in turn upon a flat rigid steel surface (which has been kept with the samples in the refrigerated cabinet) placed on the horizontal surface of a compact rigid block with a mass of at least 100 kg and within 30 seconds of being removed from the refrigerated cabinet, an 18 kg steel mass shall be allowed to fall under gravity through 300 mm on to the test sample. The impact face of the 18 kg mass shall take the form of a convex surface with a hardness of at least 45 HRC having a transverse radius of 10 mm and a longitudinal radius of 150 mm placed along the centre line of the mass. One test sample shall be tested with the axis of the curved bar in line with the strap and the other sample shall be tested at 90o to the strap.
            
         
               7.5.5.
            
            
               Buckles having parts common to two safety-belts shall be loaded in such a way as to simulate the conditions of use in the vehicle with seats in the mid position of their adjustment. A load of 1 470 daN shall be applied sumultaneously to each strap. The direction of the application of load shall be established according to paragraph 7.7.1 below. A suitable device for the test is shown in Annex 10 to this Regulation.
            
         
               7.5.6.
            
            
               When testing a manually adjusting device, the strap shall be drawn steadily through the adjusting device, having regard for the normal conditions of use, at a rate of approximately 100 mm/s and the maximum force measured to the nearest 0,1 daN after the first 25 mm of strap movement. The test shall be carried out in both directions of strap travel through the device, the strap being cycled 10 times prior to the measurement.
            
         7.6.   Additional tests for safety-belts with retractors

               7.6.1.1.
            
            
               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 snatch to lock the retractor shall be introduced at each fifth cycle.
               The snatches shall 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 remaining wound on the retractor. However, where more than 900 mm is provided the above percentages shall be related to the final 900 mm of strap which can be withdrawn from the retractor.
            
         
               7.6.1.2.
            
            
               A suitable apparatus for the tests specified in paragraph 7.6.1.1 above is shown in Annex 3 to this Regulation.
            
         7.6.2.   Locking of emergency locking retractors
   
               7.6.2.1.
            
            
               The retractor shall be tested once for locking when the strap has been unwound to full length less 300 ± 3 mm.
            
         
               7.6.2.1.1.
            
            
               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.
            
         
               7.6.2.1.2.
            
            
               When retractors are being tested for sensitivity to vehicle deceleration they shall be tested at the above extraction along two perpendicular axes, which are horizontal if the retractor is installed in a vehicle as specified by the safety-belt manufacturer. When this position is not specified, the testing authority shall consult the safety-belt manufacturer. One of these axes shall be in the direction chosen by the technical service conducting the approval test to give the most adverse conditions with respect to actuation of the locking mechanism.
            
         
               7.6.2.2.
            
            
               A suitable apparatus for the tests specified in paragraph 7.6.2.1 above is described in Annex 4 to this Regulation. The design of any such test apparatus shall ensure that the required acceleration is given before the webbing is withdrawn out of the retractor by more than 5 mm and that the withdrawal takes place at an average rate of increase of acceleration of at least 25 g/s (7) and not more than 150 g/s (7).
            
         
               7.6.2.3.
            
            
               To check conformity with the requirements of paragraphs 6.2.5.3.1.3 and 6.2.5.3.1.4, the retractor shall be mounted on a horizontal table and the table tilted with a speed not exceeding 2o per second until locking has occurred. The test shall be repeated with tilting in other directions to ensure that the requirements are fulfilled.
            
         7.6.3.   Dust resistance
   
               7.6.3.1.
            
            
               The retractor shall be positioned in a test chamber as described in Annex 5 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 7.6.3.2 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 · 105 +0,5 · 105 Pa entering through an orifice, 1,5 ±0,1 mm in diameter.
            
         
               7.6.3.2.
            
            
               The dust used in the test described in paragraph 7.6.3.1 above shall consist of about 1 kg of dry quartz. The particle size distribution is 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.
                        
                     
         7.6.4.   Retracting forces
   
               7.6.4.1.
            
            
               The retracting force shall be measured with the safety-belt assembly fitted to a dummy as for the dynamic test prescribed in paragraph 7.7. 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. In the case of a safety-belt with tension-reducing device, the retracting force and strap tension shall be measured with the tension-reducing device in both operation mode and non-operation mode.
            
         
               7.6.4.2.
            
            
               Before the dynamic test described in paragraph 7.7 the seated dummy, which is clothed with a cotton shirt, shall be tilted frontward until 350 mm of the strap is withdrawn from retractor, and then released to the initial position.
            
         7.7.   Dynamic test of belt assembly or of the restraint system
   
               7.7.1.
            
            
               The belt assembly shall be mounted on a trolley equipped with the seat and the anchorage defined in Annex 6 to this Regulation. However, if the belt assembly is intended for a specific vehicle or for specific types of vehicle, the distances between the manikin and the anchorages shall be determined by the service conducting the tests, either in conformity with the instructions for fitting supplied with the belt or in conformity with the data supplied by the manufacturer of the vehicle. If the belt is equipped with a belt adjustment device for height such as defined in paragraph 2.9.6 above, the position of the device and the means of securing it shall be the same as those of the vehicle design.
               In that case, when the dynamic test has been carried out for a type of vehicle it need not be repeated for other types of vehicle where each anchorage point is less than 50 mm distant from the corresponding anchorage point of the tested belt. Alternatively, manufacturers may determine hypothetical anchorage positions for testing in order to enclose the maximum number of real anchorage points.
            
         
               7.7.1.1.
            
            
               In the case of a safety-belt or restraint system forming part of an assembly for which type approval is requested as a restraint system, the safety-belt shall be mounted on the part of the vehicle structure to which the restraint system is normally fitted and this part shall be rigidly attached to the test trolley in the way prescribed in paragraphs 7.7.1.2 to 7.7.1.6.
               In the case of a safety-belt or restraint system with pre-loading devices relying on component parts other than those incorporated in the belt assembly itself, the belt assembly shall be mounted in conjunction with the necessary additional vehicle parts on the test trolley in the manner prescribed in paragraphs 7.7.1.2 to 7.7.1.6.
               Alternatively, in the case where those devices cannot be tested on the test trolley, the manufacturer may demonstrate by a conventional frontal impact test at 50 km/h in conformity with the procedure ISO 3560 (1975) that the device complies with the requirements of the Regulation.
            
         
               7.7.1.2.
            
            
               The method used to secure the vehicle during the test shall not be such as to strengthen the anchorages of the seats or safety-belts or to lessen the normal deformation of the structure. No forward part of the vehicle shall be present which by limiting the forward movement of the manikin excepting the foot, would reduce the load imposed on the restraint system during the test. The parts of the structure eliminated can be replaced by parts of equivalent strength provided they do not hinder the forward movement of the manikin.
            
         
               7.7.1.3.
            
            
               A securing device shall be regarded as satisfactory if it produces no effect on an area extending over the whole width of the structure and if the vehicle or the structure is blocked or fixed in front at a distance of not less than 500 mm from the anchorage of the restraint system. At the rear the structure shall be secured at a sufficient distance rearwards of the anchorages to ensure that the requirements of paragraph 7.7.1.2 above are fulfilled.
            
         
               7.7.1.4.
            
            
               The seats shall be fitted and shall be placed in the position for driving use chosen by the technical service conducting approval tests to give the most adverse conditions with respect to strength, compatible with installing the manikin in the vehicle. The positions of the seats shall be stated in the report. The seat back, if adjustable for inclination, shall be locked as specified by the manufacturer or, in the absence of any specification, to an actual seat back angle as near as possible to 25o in the case of vehicles of categories M1 and N1 as near as possible to 15o in the case of vehicles of all other categories.
            
         
               7.7.1.5.
            
            
               For the assessment of the requirements in paragraph 6.4.1.4.1 the seat shall be regarded in its most forward driving or travelling position appropriate to the dimensions of the manikin.
            
         
               7.7.1.6.
            
            
               All the seats of any group of seats shall be tested simultaneously.
            
         
               7.7.1.7.
            
            
               The dynamic tests of the harness belt system shall be carried out without the crotch strap (assembly), if there is any.
            
         
               7.7.2.
            
            
               The belt assembly shall be attached to the manikin in Annex 7 to this Regulation as follows: a board 25 mm thick shall be placed between the back of the manikin and the seat back. The belt shall be firmly adjusted to the manikin. The board shall then be removed so that the entire length of its back is in contact with the seat back. A check shall be made to ensure that the mode of engagement of the two parts of the buckle entails no risk of reducing the reliability of locking.
            
         
               7.7.3.
            
            
               The free ends of the straps shall extend sufficiently far beyond the adjusting devices to allow for slip.
            
         
               7.7.4.
            
            
               The trolley shall then be so propelled that at the moment of impact its free running speed is 50 km/h ± 1 km/h and the manikin remains stable. The stopping distance of the trolley shall be 40 cm ± 5 cm. The trolley shall remain horizontal throughout deceleration. The deceleration of the trolley shall be achieved by using the apparatus described in Annex 6 to this Regulation or any other device giving equivalent results. This apparatus shall comply with the performance specified in Annex 8 to this Regulation.
            
         
               7.7.5.
            
            
               The trolley speed immediately before impact, the forward displacement of the manikin and the speed of the chest at a 300 mm displacement of the chest shall be measured.
            
         
               7.7.6.
            
            
               After impact, the belt assembly or restraint system and its rigid parts shall be inspected visually, without opening the buckle, to determine whether there has been any failure or breakage. In the case of restraint systems it shall also be ascertained, after the test, whether the parts of the vehicle structure which are attached to the trolley have undergone any visible permanent deformation. If there is any such deformation this shall be taken into account in any calculation made in accordance with paragraph 6.4.1.4.1.
            
         7.8.   Buckle-opening test
   
               7.8.1.
            
            
               For this test, belt assemblies or restraint devices which have already undergone the dynamic test in conformity with paragraph 7.7 above shall be used.
            
         
               7.8.2.
            
            The belt assembly shall be removed from the test trolley without the buckle being opened. A load shall be applied to the buckle by direct traction via the straps tied to it so that all the straps are subjected to the force of 
                   daN. (It is understood that n is the number of straps linked to the buckle when it is in a locked position.) In the case where the buckle is connected to a rigid part, the load shall be applied at the same angle as the one formed by the buckle and the rigid end during the dynamic test. 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. During the application of the force needed to open the buckle, the buckle shall be held by a rigid support. The load quoted above shall not exceed the limit indicated in paragraph 6.2.2.5 above. The point of contact of the test equipment shall be spherical in form with a radius of 2,5 mm ±0,1 mm. It shall have a polished metal surface.
         
               7.8.3.
            
            
               The buckle-opening force shall be measured and any failure of the buckle noted.
            
         
               7.8.4.
            
            
               After the buckle-opening test, the components of the belt assembly or of the restraint device which have undergone the tests prescribed in paragraph 7.7 above shall be inspected and the extent of the damage sustained by the belt assembly or restraint device during the dynamic test shall be recorded in the test report.
            
         7.9.   Additional tests on safety-belts with pre-loading devices
   7.9.1.   Conditioning
   The pre-loading device may be separated from the safety-belt to be tested and kept for 24 hours at a temperature of 60o ± 5 oC. The temperature shall then be raised to 100o ± 5 oC for two hours. Subsequently it shall be kept for 24 hours at a temperature of - 30o ± 5 oC. After being removed from conditioning, the device shall warm up to ambient temperature. If it has been separated it shall be fitted again to the safety-belt.
   7.10.   Test report
   
               7.10.1.
            
            
               The test report shall record the results of all the tests in paragraph 7 above and in particular the trolley speed, the maximum forward displacement of the manikin, the place — if it can be varied — occupied by the buckle during the test, the buckle-opening force, and any failure or breakage. If by virtue of paragraph 7.7.1 the anchorages prescribed in Annex 6 to this Regulation have not been respected, the test report shall describe how the belt assembly or the restraint system was installed and shall specify important angles and dimensions. The report shall also mention any distortion or breakage of the buckle that has occurred during the test. In the case of a restraint system the test report shall also specify the manner of attaching the vehicle structure to the trolley, the position of the seats, and the inclination of the seat backs. If the forward displacement of the manikin has exceeded the values prescribed in paragraph 6.4.1.3.2 above, the report shall state whether the requirements of paragraph 6.4.1.4.1 have been met.
            
         8.   REQUIREMENTS CONCERNING THE INSTALLATION IN THE VEHICLE
   8.1.   Vehicle equipment
   
               8.1.1.
            
            
               With the exception of folding seats (as defined in Regulation No 14) and seating intended solely for use when the vehicle is stationary, the seats of vehicles of categories M and N as defined in Annex 7 to the Consolidated Resolution (R.E.3) (8) (except those vehicles of categories M2 and M3 which belong to Classes I or II, according to Regulation No 36, to Class A, according to Regulation No 52 and to Classes I or II and A, according to Regulation No 107) must be equipped with safety-belts or restraint systems which satisfy the requirements of this Regulation.
            
         
               8.1.2.
            
            
               The types of safety-belts or restraint systems for each seating position where installation is required shall be those specified in Annex 16 (with which neither non-locking retractors (para. 2.14.1) nor manually unlocking retractor (para. 2.14.2) can be used). For all seating positions where lap belts type B are specified in Annex 16 lap belts type Br3 are permitted except in the case that, in use, they retract to such an extent as to reduce comfort in a notable way after normal buckling up.
            
         
               8.1.2.1.
            
            
               However, for outboard seating positions, other than front, of vehicles of the category N1 shown in Annex 16 and marked with the symbol Ø, the installation of a lap belt of type Br4m or Br4Nm is allowed, where there exists a passage between a seat and the nearest side wall of the vehicle intended to permit access of passengers to other parts of the vehicle. A space between a seat and the side wall is considered as a passage, if the distance between that side wall, with all doors closed, and a vertical longitudinal plane passing through the centre line of the seat concerned — measured at the R-point position and perpendicularly to the median longitudinal plane of the vehicle — is more than 500 mm.
            
         
               8.1.3.
            
            
               Where no safety-belts are required any type of safety-belt or restraint system conforming to this Regulation may be provided at the choice of the manufacturer. A-type belts of the types permitted in Annex 16 may be provided as an alternative to lap belts for those seating positions where lap belts are specified in Annex 16.
            
         
               8.1.4.
            
            
               On three point belts fitted with retractors, one retractor must operate at least on the diagonal strap.
            
         
               8.1.5.
            
            
               Except for vehicles of category M1 an emergency locking retractor of type 4N (para. 2.14.5) may be permitted instead of a retractor of type 4 (para. 2.14.4) where it has been shown to the satisfaction of the services responsible for the tests that the fitting of a type 4 retractor would not be practical.
            
         
               8.1.6.
            
            
               For the front outboard and the front centre seating positions shown in Annex 16 and marked with the symbol *, lap belts of the type specified on that annex shall be considered adequate where the windscreen is located outside the reference zone defined in Annex 1 to Regulation No 21.
               As regards safety-belts, the windscreen is considered as part of the reference zone when it is capable of entering into static contact with the test apparatus according to the method described in Annex 1 of Regulation No 21.
            
         
               8.1.7.
            
            
               Every seating position in Annex 16 marked with the symbol •, three-point belts of a type specified in Annex 16 shall be provided unless one of the following conditions is fulfilled, in which case two-point belts of a type specified in Annex 16 may be provided.
            
         
               8.1.7.1.
            
            
               There is a seat or other vehicle parts conforming to paragraph 3.5 of Appendix 1 to Regulation No 80 directly in front, or
            
         
               8.1.7.2.
            
            
               No part of the vehicle is in or, when the vehicle is in motion, capable of being in the reference zone, or
            
         
               8.1.7.3.
            
            
               Parts of the vehicle within the said reference zone comply with the energy absorbing requirements set out in Appendix 6 of Regulation No 80.
            
         
               8.1.8.
            
            
               With the exception of the case covered by paragraph 8.1.9, every passenger seating position which is fitted with an airbag shall be provided with a warning against the use of a rearward-facing child restraint in that seating position. The warning label, in the form of a pictogram which may include explanatory text, shall be durably affixed and located such that it is easily visible in front of a person about to install a rearward-facing child restraint on the seat in question. An example of a possible design of a pictogram is shown in Figure 1. A permanent reference should be visible at all times, in case the warning is not visible when the door is closed.

               8.1.9.
            
            
               The requirements of paragraph 8.1.8 shall not apply if the vehicle is fitted with a mechanism which senses automatically the presence of any rearward-facing child restraint, and ensures that the airbag will not be deployed when such a child restraint system is fitted.
            
         
               8.1.10.
            
            
               In the case of seats capable of being turned to or placed in other orientations, designed for use when the vehicle is stationary, the requirements of paragraph 8.1.1 shall only apply to those orientations designated for normal use when the vehicle is travelling on a road, in accordance with this Regulation.
            
         8.2.   General requirements
   
               8.2.1.
            
            
               Safety-belts, restraint systems, and Isofix child restraint systems according to Table 2 of Annex 17 — Appendix 3, shall be fixed to anchorages conforming to the specifications of Regulation No 14, such as the design and dimensional characteristics, the number of anchorages, and the strength requirements.
            
         
               8.2.2.
            
            
               The safety-belts, restraint systems, child restraint systems and Isofix child restraint systems recommended by the manufacturer according to Tables 1 and 2 of Annex 17 — Appendix 3, shall be so installed that they will work satisfactorily and reduce the risk of bodily injury in the event of an accident. In particular they shall be so installed that:
            
         
               8.2.2.1.
            
            
               The straps are not liable to assume a dangerous configuration;
            
         
               8.2.2.2.
            
            
               That the danger of a correctly positioned belt slipping from the shoulder of a wearer as a result of his/her forward movement is reduced to a minimum.
            
         
               8.2.2.3.
            
            
               The risk of the strap deteriorating through contact with sharp parts of the vehicle or seat structure, child restraint systems or Isofix child restraint systems recommended by the manufacturer according to Tables 1 and 2 of Annex 17 — Appendix 3, is reduced to a minimum.
            
         
               8.2.2.4.
            
            
               The design and installation of every safety-belt provided for each seating position shall be such as to be readily available for use. Furthermore, where the complete seat or the seat cushion and/or the seat back can be folded to permit access to rear of the vehicle or to goods or luggage compartment, after folding and restoring those seats to the seating position, the safety-belts provided for those seats shall be accessible for use or can be easily recovered from under or behind the seat, by one person, according to instructions in the vehicle users handbook, without the need for that person to have training or practice.
            
         
               8.2.2.5.
            
            
               The technical service shall verify that, with the buckle tongue engaged in the buckle and no occupant in the seat:
            
         
               8.2.2.5.1.
            
            
               The possible slack in the belt does not prevent the correct installation of child restraint systems recommended by the manufacturer, and
            
         
               8.2.2.5.2.
            
            
               In the case of three-point belts, a tension of at least 50 N can be established in the lap section of the belt by external application of tension in the diagonal section of the belt.
            
         8.3.   Special requirements for rigid parts incorporated in safety-belts or restraint systems
   
               8.3.1.
            
            
               Rigid parts, such as the buckles, adjusting devices and attachments, shall not increase the risk of bodily injury to the wearer or to other occupants of the vehicle in the event of an accident.
            
         
               8.3.2.
            
            
               The device for releasing the buckle shall be clearly visible to the wearer and within his easy reach and shall be so designed that it cannot be opened inadvertently or accidentally. The buckle shall also be located in such a position that it is readily accessible to a rescuer needing to release the wearer in an emergency.
               The buckle shall be so installed that, both when not under load and when sustaining the wearer's mass, it is capable of being released by the wearer with a single simple movement of either hand in one direction.
               In the case of a safety-belts or restraint systems for front outboard seating positions, except if these are harness belts, the buckle shall also be capable of being locked in the same manner.
               A check shall be made to ensure that, if the buckle is in contact with the wearer, the width of the contact surface is not less than 46 mm.
               A check shall be made to ensure that, if the buckle is in contact with the wearer, the contact surface satisfies the requirements of paragraph 6.2.2.1 of this Regulation.
            
         
               8.3.3.
            
            
               When the belt is being worn, it shall either adjust automatically to fit the wearer or be so designed that the manual adjusting device is readily accessible to the wearer when seated and is convenient and easy to use.

The marks which correspond to the arrangement of the anchorages show where the ends of the belt are to be connected to the trolley or to the load transducer, as the case may be. The anchorages for normal use are the points A, B and K if the strap length between the upper edge of the buckle and the hole for attachment of the strap support is not more than 250 mm. Otherwise, the points A1 and B1 shall be used. The tolerance on the position of the anchorage points is such that each anchorage point shall be situated at most at 50 mm from corresponding points A, B and K indicated in figure 1 or A1, B1 and K, as the case may be.

                  The structure carrying the anchorages shall be rigid. The upper anchorage must not be displaced by more than 0,2 mm in the longitudinal direction when a load of 98 daN is applied to it in that direction. The trolley shall be so constructed that no permanent deformation shall occur in the parts bearing the anchorages during the test.

                  The characteristics of the absorbing material are given in table 1 of this annex. Immediately before each test the tubes shall be conditioned at a temperature between 15o and 25 oC for at least 12 hours without being used. During the dynamic testing of safety-belts or restraint systems, the stopping device shall be at the same temperature as during the calibration test, with a tolerance of ± 2 oC. The requirements to be met by the stopping device are given in Annex 8 to this Regulation. Any other device giving equivalent results may be used.

            1.2.   Description of the manikin
      1.2.1.   Structure of the lower leg (see Figures 3 and 4)
      
      The structure of the lower leg consists of three components:
      
                  —
               
               
                  a sole plate (30);
               
            
                  —
               
               
                  a shin tube (29); and
               
            
                  —
               
               
                  a knee tube (26).
               
            The knee tube has two lugs which limit the movement of the lower leg in relation to the thigh.
      The lower leg can be rotated rearwards 120o from the straight position.
      1.2.2.   Structure of the thigh (see Figures 3 and 4)
      
      The structure of the thigh consists of three components:
      
                  —
               
               
                  knee tube (22),
               
            
                  —
               
               
                  a thigh bar (21), and
               
            
                  —
               
               
                  a hip tube (20).
               
            Movement of the knee is limited by two cut-outs in the knee tube (22) which engage with the lugs of the lower leg.
      1.2.3.   Structure of the torso (see Figures 1 and 2)
      
      The structure of the torso consists of:
      
                  —
               
               
                  a hip tube (2),
               
            
                  —
               
               
                  a roller chain (4),
               
            
                  —
               
               
                  ribs (6) and (7),
               
            
                  —
               
               
                  a sternum (8), and
               
            
                  —
               
               
                  chain attachments (3) and at parts (7) and (8).
               
            1.2.4.   Neck (see Figures 1 and 2)
      
      The neck consists of seven polyurethane discs (9). The stiffness of the neck can be adjusted by means of a chain tensioner.
      1.2.5.   Head (see Figures 1 and 2)
      
      The head (15) itself is hollow; the polyurethane form is reinforced by steel plate (17). The chain tensioner by which the neck can be adjusted consists of a polyamide block (10), a tubular spacer (11), and tensioning members (12) and (13). The head can be turned about the Atlas-Axis joint, which consists of the adjuster assembly (14) and (18), the spacer (16), and polyamide block (10).
      1.2.6.   Knee joint (see Figure 4)
      
      The lower leg and thighs are connected by a tube (27) and a tensioner (28).
      1.2.7.   Hip joint (see Figure 4)
      
      The thighs and torso are connected by a tube (23), friction plates (24), and tensioner assembly (25).
      1.2.8.   Polyurethane
      
                  Type
               
               
                  :
               
               
                  PU 123 CH Compound
               
            
                  Hardness
               
               
                  :
               
               
                  50-60 Shore A
               
            1.2.9.   Overalls
      The manikin is covered by a special overall (see table 1).
      2.   CORRECTION DEVICES
      2.1.   General
      In order to calibrate the manikin to certain values and its total mass, the mass distribution are adjusted by the use of six correction steel masses of 1 kg each, which can be mounted at the hip joint. Six polyurethane weights each of 1 kg mass can be mounted in the back of the torso.
      3.   CUSHION
      A cushion must be positioned between the chest of the manikin and the overall. This cushion shall be made of polyethylene foam of the following specification:
      
                  
                              —
                           
                           
                              Hardness:
                           
                        
               
                  7-10 shore A
               
            
                  
                              —
                           
                           
                              Thickness:
                           
                        
               
                  25 mm ± 5
               
            It shall be replaceable.
      4.   ADJUSTMENT OF THE JOINTS
      4.1.   General
      In order to achieve reproducible results, it is necessary to specify and control the friction at each joint.
      4.2.   Knee joint
      Tighten the knee joint.
      Set the thigh and lower leg vertical.
      Rotate the lower leg through 30o.
      Gradually slacken the tensioner (28) until the lower leg starts to fall under its own mass.
      Lock the tensioner in this position.
      4.3.   Hip joint
      Tighten the hip joint.
      Place the thigh in a horizontal position and the torso in a vertical position.
      Rotate the torso in a forward direction until the angle between the torso and the thigh is 60o.
      Gradually slacken the tensioner until the torso starts to fall under its own mass.
      Lock the tensioner in this position.
      4.4.   Atlas-Axis joint
      Adjust the Atlas-Axis joint so that it just resists its own weight in the fore and aft directions.
      4.5.   Neck
      The neck can be adjusted by means of the chain tensioner (13). When the neck is adjusted, the upper end of the tensioner shall displace between 4—6 cm when subjected to a horizontal load of 10 daN.

      DESCRIPTION OF CURVE OF TROLLEY'S DECELERATION AS A FUNCTION OF TIME
      (Curve for testing stopping devices)
      
         
      The deceleration curve of the trolley weighted with inert mass to produce a total mass of 455 kg ± 20 kg for safety-belt tests and 910 ± 40 kg for restraining system tests where the nominal mass of the trolley and vehicle structure is 800 kg must remain within the hatched area above. If necessary, the nominal mass of the trolley and attached vehicle structure can be increased by increments of 200 kg, in which case, an additional inert mass of 28 kg per increment shall be added. In no case shall the total mass of the trolley and vehicle structure and inert masses differ from the nominal value for calibration tests by more than ± 40 kg. During calibration of the stopping device, the speed of the trolley shall be 50 km/h ± 1 km/h and the stopping distance shall be 40 cm ± 2 cm. In both the above cases the calibration and measuring procedures shall correspond to those defined in the International Standard ISO 6487:1980; the measuring equipment shall correspond to the specification of a data channel with a channel frequency class (CFC) 60.

                  1.1.
               
               
                  The apparatus shall consist of a mist chamber, a salt solution reservoir, a supply of suitably conditioned compressed air, one or more atomizing nozzles, sample supports, provision for heating the chamber, and necessary means of control. The size and detail construction of the apparatus shall be optional, provided that the test conditions are met.
               
            
                  1.2.
               
               
                  It is important to ensure that drops of solution accumulated on the ceiling or cover of the chamber do not fall on test samples.
               
            
                  1.3.
               
               
                  Drops of solution which fall from test samples shall not return to the reservoir for respraying.
               
            
                  1.4.
               
               
                  The apparatus shall not be constructed of materials that will affect the corrosiveness of the mist.
               
            2.   LOCATION OF TEST SAMPLES IN THE MIST CABINET
      
                  2.1.
               
               
                  Samples, except retractors, shall be supported or suspended between 15o and 30o from the vertical and preferably parallel to the principal direction of horizontal flow of mist through the chamber, based upon the dominant surface being tested.
               
            
                  2.2.
               
               
                  Retractors shall be supported or suspended so that the axes of the reel for storing the strap shall be normal to the principal direction of horizontal flow of mist through the chamber. The strap opening in the retractor shall also be facing in this principal direction.
               
            
                  2.3.
               
               
                  Each sample shall be placed so as to permit free setting of mist on all samples.
               
            
                  2.4.
               
               
                  Each sample shall be so placed as to prevent salt solution from one sample dripping on to any other sample.
               
            3.   SALT SOLUTION
      
                  3.1.
               
               
                  The salt solution shall be prepared by dissolving 5 + 1 parts by mass of sodium chloride in 95 parts of distilled water. The salt shall be sodium chloride substantially free of nickel and copper and containing on the dry basis not more than 0,1 per cent of sodium iodide and not more than 0,3 per cent of total impurities.
               
            
                  3.2.
               
               
                  The solution shall be such that when atomized at 35 oC the collected solution is in the pH range of 6,5 to 7,2.
               
            4.   AIR SUPPLY
      The compressed air supply to the nozzle or nozzles for atomizing the salt solution shall be free of oil and dirt, and maintained at a pressure between 70 kN/m2 and 170 kN/m2.
      5.   CONDITIONS IN THE MIST CHAMBER
      
                  5.1.
               
               
                  The exposure zone of the mist chamber shall be maintained at 35 ± 5o C. At least two clean mist collectors shall be placed within the exposure zone so that no drops of solution from the test samples or any other sources are collected. The collectors shall be placed near the test samples, one nearest to any nozzle and one furthest from all nozzles. The mist shall be such that for each 80 cm2 of horizontal collecting areas, there is collected in each collector from 1,0 to 2,0 ml of solution per hour when measured over an average of at least 16 hours.
               
            
                  5.2.

                  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. below):
               
            
                  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 co-ordinate 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.

                  3.2.1.
               
               
                  The co-ordinates of the ‘H’ point and the value of the actual torso angle obtained by the procedure set out in paragraph 4 below shall be compared, respectively, with the co-ordinates 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 co-ordinates, 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 5o 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.

                  If the ‘H’ point or the actual torso angle does not satisfy the requirements of paragraph 3.2.2 above, 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 above shall apply.
               
            
                  3.2.5.
               
               
                  If the results of at least two of the three operations described in paragraph 3.2.4 above do not satisfy the requirements of paragraph 3.2.2 above, 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 oC 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 above.
               
            
                  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 above 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 10o arc (5o 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 spirit levels for zero position. If any movement of the feet has occurred during the rocking operation of the 3-D H machine, they must be repositioned as follows:
                  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 co-ordinates 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 minutes 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.

         (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.
