than 3 milliseconds when no peak shall exceed 200 times the acceleration due to gravity.  Deceleration peaks exceeding 200 times the acceleration due to gravity and of very short duration are permissible if it can be shown that they are due to ringing of the test equipment.
         11.3.4                             Test Procedure
         11.3.4.1                       Test sample shall be a right square prism with plane dimensions at least l00 mm by l00 mm.  It shall consist of the energy absorbing materials used in the 'Sun Visor' with a thickness equal to their minimum thickness measured at any point 25 mm or more from the edge of the 'Sun Visor'.  Alternatively the test sample may be the 'Sun Visor' itself.  In this case the requirements shal1 be met for impact at any point more than 40 mm from the edge of the 'Sun Visor'.  The test sample shall be conditioned for at least 6 hours at 25 ± 5°C and tested at that temperature.
         11.3.4.2                       The dynamic testing equipment shall consist of a rigid moving head having an effective mass of 6.8 ± 0.l kg and a rigid anvil having a mass of at least 300 kg.  The moving head and anvil should have sufficient rigidity to obviate undesirable vibrations in the equipment.  The portion of the moving head which contacts the test sample must be of spherical shape with a diameter of 165 mm.  The face of the anvil should be perpendicular to the direction of travel of the moving head just prior to impact.  However, where a 'Sun Visor' of tapered thickness is being tested, the anvil may be tilted or a rigid support provided, to ensure that the surface of the 'Sun Visor' at the impact point is perpendicular to the direction of travel of the moving head.
         11.3.4.3                       The moving head shall impact the test sample at a velocity of not less than 3.5 m/s and a means of measuring this velocity shall be provided.
         11.3.4.4                       A transducer shall be mounted on the moving head such that a complete deceleration time curve is obtained using an oscilloscope or other recording device.  The deceleration channel must have a frequency response flat to within ± 5 per cent from one to 1000 Hz.
         11.4                                   ALTERNATIVE  STANDARDS
         The energy absorption requirements of this vehicle standard shall be deemed to be satisfied if the 'Sun Visor' has satisfied the requirements of Annex 4 "Procedures for Testing Energy-Dissipating Materials" of  United Nations Economic Commission for Europe Regulation 21/01 Uniform Provisions Concerning the Approval of Vehicles with Regard to Their Interior Fittings.
