              14.1. General specifications
              14.1.1. The audible warning device, audible warning system, multiple audible warning system shall be so designed, constructed and assembled as to enable the vehicle, in normal use, despite the vibration to which it may be subjected, to comply with the provisions of this Regulation.
              14.1.2. The audible warning device(s), audible warning system(s), multiple audible warning system(s) and its (their) mounting elements to the vehicle shall be so designed, constructed and assembled as to be able to reasonably resist the corrosive phenomena to which it is exposed with regards to the conditions of use of the vehicle, including regional climate differences.
              14.2.  Specifications regarding sound levels
              14.2.1. The sound made by the audible warning device(s), audible warning system(s), multiple audible warning system(s) fitted to the vehicle type submitted for approval shall be measured by the methods described in paragraph 14.3.;
              14.2.2. Measured under the conditions specified in paragraphs 14.3. the sound-pressure level of the audible warning signal tested shall be at least:

                  (a)  Equal to 83 dB (A) and not more than 112 dB (A) for the signals of vehicles of categories L3 to L5 of a power less than or equal to 7 kW;

                  (b)  Equal to 87 dB (A) and at most 112 dB (A) for the signals of vehicles of categories M, N and L3 to L5 of a power greater than 7 kW.
