C-24.2, r. 9.001 - Regulation respecting the control of sound emissions produced by the exhaust system of motorcycles and mopeds

Full text
1. In this Regulation,
dBA (A-weighted decibel) means the value, in decibels, of the sound pressure level measured using the A-weighted frequency and defined in ISO Standard 1996-1: 2016 published by the International Organization for Standardization or ANSI/ASA Standard S1.4-2014 published by the American National Standards Institute and IEC Standard 61672-1: 2013 published by the International Electrotechnical Commission; (dBA)
engine speed or rotational speed of the engine means the rotational speed of the engine expressed in revolutions per minute (RPM); (régime moteur) (vitesse de rotation du moteur);
method where the engine is idling means the method that consists in measuring the sound level where the engine is running but the throttle is not activated; (méthode où le moteur tourne au ralenti)
method where the engine runs at a constant speed means the method that consists in maintaining, during measurement, the rotational speed of the engine at a determined value; (méthode où le moteur tourne à vitesse constante)
method where the engine runs at a variable speed means the method that consists in progressively increasing, during measurement, the rotational speed of the engine, from idle speed to a determined value; idle speed is where the engine is running but the throttle is not activated; (méthode où le moteur tourne à vitesse variable).
series of measurements means a set of measurements taken with the same sound level meter, on the same premises, on the same day, by the same peace officers and in similar conditions; that set of measurements may concern a number of motorcycles and mopeds. (série de mesures)
