Q-2, r. 48 - Regulation respecting hot mix asphalt plants

Full text
(s. 1)
The value retained for each octave is the minimum value during a period of 30 seconds, at the evaluation point. If the hot mix asphalt plant produces a noise during a period that lasts less than 30 seconds, the measurements are taken during the emission period.
Octave band analysis is made in linear dB using the slow response on the sound level meter.
Every octave band analysis is made using a sound level meter and octave band filters that comply with the standards in Schedule B.
