19.3.2.5.2.              the closing of a power window of a vehicle's door without upper door frame closes from an opening not exceeding 12 mm whenever the pertinent door is closed.
19.3.2.6.                    Notwithstanding clauses 19.3.2.1 and 19.3.2.4, a power operated window system may close if it is capable of the following requirements:
19.3.2.6.1.              while closing, the window reverses direction before exerting a pinch force of 100N or more within the range of 200 mm to 4 mm beneath the top edge of the power window frame.
19.3.2.6.2.              upon such reversal, the window must open to one of the following positions:
         A position that permits a cylindrical rod 200 mm in diameter to be placed through the opening at the top edge of the window.
         A position that is at least as open as the position at the time closing was initiated.
         A position at least 50 mm more open than the position at the time reversing was initiated.
19.3.2.6.3.              To check these devices, a measuring instrument/test rod is placed through the window 'Opening' from the inside of the vehicle such that the cylindrical surface of the rod contacts the structure which forms the boundary of the window.  The force/deflection ratio of the measuring instrument/test rod must be at least 10 N/mm. Placements of the test rods are illustrated in Figure 6.
19.3.2.6.4.              The technical requirements of FMVSS 118-FR VOL36 No. 232-02.12.1971- Power Operated Window System; as amended by FMVSS 118-FR VOL58 No. 60-31.03.1993 are deemed to be equivalent to the technical requirements of clause 19.3 of this national standard.
20.                                      WARNING DEVICES - AUDIBLE
20.1.                                General
20.1.1.                          No siren, repeater horn, bell, exhaust whistle or compression whistle or other device capable of producing a sound resembling that produced by any such siren, repeater horn, bell or whistle must be attached to a motor vehicle other than an emergency community service vehicle.
20.1.2.                          For the purpose of this clause, a repeater horn is any device which generates an audible sound (to be emitted) alternating between different tones or frequencies on a regular time cycle.
20.2.                                Warning Device
         Every motor vehicle must be fitted with a least one warning device capable of giving sufficient audible warning of the presence of the vehicle.  It must give an audible signal having constant amplitude and frequency characteristics.  It may be powered by any energy source including compressed air.
20.3.                                Reversing Alarm
         Notwithstanding clauses 20.1 and 20.2 a further device may be fitted which when and only when reverse gear is selected emits an intermittent audible signal on a regular time cycle.  It must not emit a signal louder than is necessary to warn persons of the proximity of the reversing vehicle.
20.3.1.                          For vehicles of
