This standard defines the method for measuring the noise level of a vehicle security-sounding device. This standard does not define or limit device under test (DUT) frequencies, sounds or tones. However, this standard limits the frequencies that the noise level measurements may measure. Only frequencies between 500 Hz and 3,500 Hz shall be accepted for measurement purposes. If the DUT has multiple frequencies, only those that are within these limits shall be acceptable for measurement. Suitable spectral analysis equipment shall be used for the analysis of the frequencies emitted by the DUT. This need not be done at the time of testing.
