a sinusoidal vibration mode whose characteristics are as follows :
7.2.8.2.1. For type 1
 The frequency shall be variable from 10 Hz to 500 Hz with a maximum amplitude of ± 5 mm and maximum acceleration of 3 g
(0-peak).
7.2.8.2.2. For type 2
The frequency shall be variable from 20 Hz to 300 Hz with a maximum amplitude of ± 2 mm and maximum acceleration of 15 g
(0-peak).
7.2.8.2.3. For both type 1 and type 2 :
 the frequency variation is 1 octave/min;
 the number of cycles is 10, the test shall be performed along each of the 3 axes;
 the vibrations are applied at low frequencies at a maximum constant amplitude and at a maximum constant acceleration at high frequencies.
7.2.8.3. During the test the VAS shall be electrically connected and the cable shall be supported after 200 mm.
7.2.8.4. After the vibration test the operation tests according to paragraph 7 2.1. shall be repeated.
7.2.9. Durability test
 Under the test conditions specified in paragraph 7.2.1.2., triggering of 300 complete alarm cycles (audible and/or optical) with a rest time of the audible device of 5 min.
7.2.10. Tests for external key switch (installed on the outside of the vehicle)
 The following tests shall only be performed if the locking cylinder of the original equipment door lock is not used.
7.2.10.1. The key switch shall be so designed and constructed that it remains fully effective even after :
 2,500 set/unset cycles in each direction, followed by
 96 hours minimum of exposure to salt spray test according to IEC 68-2-11-1981, corrosion resistance test.
7.2.11. Test of systems for the protection of the passenger compartment
 The alarm shall be activated, when a vertical panel of 0.2 x 0.15 m is inserted for 0.3 m (measured from the centre of the vertical panel) through an open front door window into the passenger compartment, towards the front and parallel to the road at a speed of 0.4 m/s and at an angle of 45 with the longitudinal median plane of the vehicle. (See drawings in Annex 8 to this Regulation).
7.2.12. Electromagnetic compatibility
 The VAS shall be submitted to the tests described in Annex 9.
7.2.13. Safety against false alarm in the event of an impact on the vehicle
 It shall be verified that an impact of up to 4.5 Joules of a hemispherical body with 165 mm in diameter and 70 ± 10 Shore A applied anywhere to the vehicle bodywork or glazing with its curved surface does not cause false alarms.
7.2.14. Safety against false alarm in the event of a voltage reduction
 It shall be verified that slow reduction of the main battery voltage by continuous discharge of 0.5
