6.4.                                        The extent of the protection provided shall be as follows:

 

6.4.1.                                  The shell shall cover all areas above plane AA' and shall extend downwards at least as far as the lines CDEF on both sides of the headform (see annex 4, fig. 1 A).

 

6.4.2.                                  At the rear, the rigid parts and, in particular, the shell shall not be within a cylinder defined as follows (see annex 4,

fig. 1 B):

 

(i)                     Diameter 100 mm;

 

(ii)                   Axis, situated at the intersection of the medium plane of symmetry of the headform and of a plane parallel to and

110 mm below the reference plane.

 

6.4.3.                                  The protective padding shall cover all the areas defined in paragraph 6.4.1., account being taken of the requirements of paragraph 6.5.

 

6.5.                                        The helmet shall not dangerously affect the wearer's ability to hear. The temperature in the space between the head and the shell shall not rise inordinately; to prevent this, ventilation holes may be provided in the shell.

 

Where means for attaching a visor are not provided, the profile at the front edge shall not prevent the wearing of goggles.

 

 

 

 

 

 

 

 

 

 

6.6.                                        All projections from or irregularities in the outer surface of the shell greater than 2 mm shall be tested for shear assessment according               to paragraphs 7.4.1. or 7.4.2. The outer surface of the helmet shall be tested for friction assessment according to paragraphs 7.4.1. or 7.4.2.   This applies in particular to a movable lower face cover in all positions intended by the manufacturer.

6.7.                                            All external projections shall be radiused and any external projections other than press-fasteners shall be smooth and adequately faired.

 

6.7.1.                                      All external projections not more than 2 mm above the outer surface of the shell (e.g. rivet heads) shall have a radius of a minimum of 1 mm.

 

6.7.2.                                      All external projections more than 2 mm above the outer surface of the shell shall have a radius of a minimum of 2 mm.

 

The latter specific requirements shall not apply if a projection satisfies the requirements in paragraphs 7.4.1. or 7.4.2. below.

 

6.8.                                            There shall be no inward-facing sharp edges on the inside of the helmet; rigid, projecting internal parts shall be covered with padding so that any stresses transmitted to the head are not highly concentrated.

 

6.9.                                            The various components of the protective helmet, except a detachable or movable protective or non protective lower face cover shall be so assembled that they are not liable to become easily detached as a result of an impact.

 

6.10.                                        Retention systems shall be protected from abrasion.

 

6.11.                                        The helmet shall be held in place on the wearer's head by means of a retention system which is secured under the lower jaw.               All parts of the retention system shall be permanently attached to the system or to the helmet.

 

6.11.1.                                  If the retention system includes a chin-strap, the strap shall be not less than 20 mm wide under a load of 150 N ± 5 N applied under the condition prescribed in paragraph 7.6.2.

 

6.11.2.                                  The chin strap shall not include a chin-cup.

 

6.11.3.                                  Chin straps shall be fitted with a device to adjust and maintain tension in the strap.

 

6.11.4.                                  Chin strap fastening and tensioning devices shall be positioned on the straps either so that there are no rigid parts extending more than 130 mm vertically below the headform reference plane with the helmet mounted on the appropriate sized headform, or so that the whole of the device is between the bony projections of the underside of the lower jaw.

 

6.11.5.                                  If the retention system includes either a double-D ring or sliding bar fastening device then means shall be provided to prevent the retention system being completely undone and also to retain the free end of the strap when the retention system is adjusted .

 

 

 

 

Retaining systems using closing rings ("double D") or a "roller buckle" shall be conceived to prevent the total opening of the system and to maintain the strap in the desired position once the retaining system has been adjusted.

If the retaining system can be opened completely, must be possible only with voluntary action. To prevent any possible misuse the helmet must be provided with detailed instructions on the use of the buckle.

 

6.11.6.                                  Sliding bar and double-D ring fastening devices shall be fitted with a pulling flap to be used for releasing the retention system.               Its colour must be red and its minimum dimensions must be 10 x 20 mm.

 

6.11.7.                                  If a retention system includes a quick-release mechanism, then the method of release of this mechanism shall be self-evident. Any levers, tabs, buttons or other components which need to be operated to release the mechanism shall be coloured red, those parts of the rest of the system which are visible when closed shall not be similarly coloured, and the mode of operation shall be permanently indicated.

 

6.11.8.                                  The retention system shall remain closed when the tests described in paragraphs 7.3., 7.6. and 7.7. are carried out.

 

6.11.9.                                  The buckle of the retention system shall be designed so as to preclude any possibility of incorrect manipulation.               This means, inter alia , that it must not be possible for the buckle to be left in a partially closed position.

 

6.12.                                        If the lower face cover is detachable or movable, the lower face cover shall be fitted with a device that locked into the intended position. The device must be such that incorrect handling is impossible. The control/actuating device must be the shade of red. The helmet has to comply with the requirements for helmets category “J” or rather category ,“P” or both.

 

 

6.13.                                        The characteristics of the materials used in the manufacture of helmets shall be known not to undergo appreciable alteration under the influence of ageing, or of the circumstances of use to which the helmet is normally subjected, such as exposure to sun, extremes of temperature and rain.               For those parts of the helmet coming into contact with the skin, the materials used shall be known not to undergo appreciable alteration through the effect of perspiration or of toilet preparations.               The manufacturer shall not use materials known to cause skin troubles.               The suitability of a proposed new material shall be established by the manufacturer.

 

6.14.                                        After the performance of one of the prescribed tests, the protective helmet shall not exhibit any breakage or deformation dangerous to the wearer.

 

6.15.                                         Peripheral vision

 

6.15.1.                                  To carry out the test, the technical service shall select from among the existing sizes of a helmet type the size it considers likely to yield the least favourable result;

 

6.15.2.                                  The helmet shall be placed on the headform corresponding to its size by the procedure set out in annex 5 to this Regulation;

 

 

 

 

6.15.3.                                  In the above conditions there shall be no occultation in the field of vision bounded by:               (see annex 4, figs. 2A, 2B and 2C)

 

6.15.3.1.                            horizontally : two segments of dihedral angles symmetrical in relation to the median longitudinal vertical plane of the headform and situated between the reference and the basic planes.

Each of these dihedral angles is defined by the median longitudinal vertical plane of the headform and the vertical plane forming an angle of not less than 105° with the median longitudinal vertical plane and whose edge is the straight line LK;

 

6.15.3.2.                            upwards : a dihedral angle defined by the reference plane of the headform and a plane forming an angle of not less than with the reference plane and whose edge is the straight line L 1 L 2 , the points L 1 and L 2 representing the eyes;

 

6.15.3.3.                            downwards : a dihedral angle defined by the basic plane of the headform and a plane forming an angle of not less than 45° with the basic plane and whose edge is the straight line K 1 K 2 .

 

6.16.                                        Visors

 

6.16.1.                                  The systems of attachment of a visor to a helmet shall be such that the visor is removable.               It must be possible to manoeuvre the visor out of the field of vision with a simple movement of one hand.               However, the latter prescription may not be required for helmets which do not provide chin protection provided that a label is attached to the helmet to the effect of warning the purchaser that the visor cannot be manoeuvred.

 

6.16.2.                                  Angle opening (see annex 9)

 

6.16.3.                                  Field of vision

 

6.16.3.1.                            The visor shall not comprise any part liable to impair the user's peripheral vision as defined in paragraph 6.14. when the visor is in the totally opened position.               Furthermore, the lower edge of the visor shall not be situated in the downward field of vision of the user as defined in paragraph 6.14. when the visor is in closed position. The surface of the visor in the peripheral field of vision of the helmet may however include:

 

(i)                 The lower edge of the visor, provided that it is made of a material with at least the same transmittance as the rest of the visor,

 

(ii)                A device to allow the visor to be manoeuvred. However, if this device is situated within the field of vision of the visor defined in paragraph 6.15.3.2. below it shall be at the lower edge and present a maximum height (h) of 10 mm and its width (l) shall be such that the product (h x l)

at the most is equal to 1.5 cm 2 . Moreover, it must be made

of a material with at least the same transmittance as the visor and it must be free of any engraving, paint or other covering feature,


 

 

(iii)              Fixings and devices to allow the visor to be manoeuvred if they are situated outside of the field of vision of the visor and if the total surface of these parts, including devices, if any, to allow the visor to be manoeuvred does not exceed 2 cm 2 , possibly distributed on each side of the field of vision.

 

6.16.3.2.                            The field of vision of the visor is defined by:

 

(a)               A dihedron defined by the reference plane of the headform and a plane forming an angle of at least upwards, its edge being the straight line L 1 L 2 , with points L 1 and L 2 representing the eyes,

 

(b)               Two segments of dihedral angles symmetrical to the median vertical longitudinal plane of the headform.               Each of these dihedral angles is defined by the median vertical longitudinal plane of the headform and the vertical plane forming with this plane an angle of 90°, its edge being the straight line LK,

 

(c)                and the lower edge of the visor.

 

6.16.3.3.                            To determine the field of vision as defined in

paragraph 6.15.3.2. above, the helmet fitted with the visor being tested shall be placed on a test headform of suitable size in accordance with the provisions of paragraph 7.3.1.3.1., with the helmet tipped towards the rear as specified in

paragraph 7.3.1.3.1. and the visor placed in the closed

position.

 

6.16.3.4.                            Visors shall have a luminous transmittance τ 80%, relative to the standard illuminant D65. A luminous transmittance

80% > τ [35] %, meas u red by the method given in

paragraph 7.8.3.2.1.1. , is also permissible if the visor is marked with the symbol shown in figure 2 and/or with the English words DAYTIME USE ONLY . The luminous transmittance shall be measured before the abrasion test.

Note: this symbol or indication must visible and extend over at

least [1] cm 2


 

 

 

6.16.3.5.                            Visors shall be free from any significant defects likely to impair the vision, such as bubbles, scratches, inclusions, dull spots, holes, mould marks, scratches or other defects originating from the manufacturing process in the field of vision.               The light diffusion shall not exceed the limit in accordance with paragraph 7.8.3.2.1.2. when measured in accordance with one of the methods specified in annex 11.

 

If different results arise when this is assessed, the requirements on scattered light shall be measured and assessed over an area 5 mm in diameter which includes the presumed error. In addition, the regular transmittance shall not deviate by more than " 5 per cent from the reference value, measured in one of two sight points specified in paragraph 6.15.3.8., at any point within the field of vision of the visor.

 

6.16.3.6.                            Visors shall in addition be sufficiently transparent, shall not cause any noticeable distortion of object as seen through the visor, shall be resistant to abrasion, resistant to impact and shall not give rise to any confusion between the colour used in road traffic sign and signals. The relative visual attenuation quotient (Q) shall not be less than:
