SCHEDULE V.1(Section 5)

  • [SOR/97-141, s. 4;
  • SOR/97-421, s. 15.]

Noise Emissions (Standard 1106)

Interpretation

  • 1. The definitions in this section apply in this Schedule and in the documents referred to in this Schedule.

    “dBA”

    “dBA” means the A-weighted sound level in decibels, measured using a sound level meter or a sound data acquisition system referred to in Appendix A of Test Method 1106 — Noise Emission Tests (August 2005) that uses the values set out in Table 1 of that Appendix. (dBA)

    “decibel”

    “decibel” or “dB” means 20 times the logarithm to the base 10 of the ratio of the measured sound pressure relative to a reference sound pressure of 20 µPa. (décibel ou dB)

    “rated engine speed”

    “rated engine speed” or “maximum rated engine speed” means the rotational speed of an engine in revolutions per minute (RPM) at which the maximum horsepower of the engine is attained. (régime maximal nominal, rated engine speed ou maximum rated engine speed)

    “sound level”

    “sound level” means the root-mean-square of the values measured in dBA that are recorded during testing conducted pursuant to this section. (niveau sonore)

    • SOR/2005-342, s. 6.

Exterior Sound Level

  • 2. Every vehicle, other than a motorcycle or a vehicle referred to in section 4, shall be so constructed that

    • (a) where tested in accordance with Annex 3 to ECE Regulation No. 51, Uniform Provisions concerning the Approval of Motor Vehicles Having at Least Four Wheels with regard to Their Noise Emissions, dated March 11, 1996, excluding the requirements of paragraph 3.2 of that Annex, the vehicle conforms to section 6 of that Regulation; or

    • (b) where tested in accordance with

      • (i) section 3 of Test Method 1106 — Noise Emission Tests (August 2005), the exterior sound level does not exceed 83 dBA when a value of 2 dBA is subtracted from the highest average sound level recorded during the test, in the case of a bus with a GVWR of more than 4 536 kg,

      • (ii) SAE Recommended Practice J986, Sound Level for Passenger Cars and Light Trucks (August 1994), or SAE Standard J1470, Measurement of Noise Emitted by Accelerating Highway Vehicles (March 1992), the exterior sound level does not exceed 83 dBA when a value of 2 dBA is subtracted from the highest average sound level recorded during the test, in the case of a bus, multi-purpose passenger vehicle, truck or incomplete vehicle fitted with a cab with a GVWR of more than 2 722 kg and not more than 4 536 kg, and

      • (iii) SAE Recommended Practice J986, Sound Level for Passenger Cars and Light Trucks (August 1994), or SAE Standard J1470, Measurement of Noise Emitted by Accelerating Highway Vehicles (March 1992), the exterior sound level does not exceed 80 dBA when a value of 2 dBA is subtracted from the highest average sound level recorded during the test, in the case of a passenger car regardless of its GVWR or any other vehicle with a GVWR of 2 722 kg or less.

      • (ii) 80 dBA, in the case of a motorcycle with an engine displacement exceeding 80 cm3 and not exceeding 175 cm3, and

      • (iii) 82 dBA, in the case of a motorcycle with an engine displacement exceeding 175 cm3; or

    • (b) where tested in accordance with

      • (i) Appendix I-2 to subparts D and E, part 205, chapter I, title 40 of the United States Code of Federal Regulations, as amended by Vol. 45, No. 252 of the Federal Register of the United States published on December 31, 1980, at pages 86727 and 86728, the exterior sound level does not exceed 70 dBA, in the case of a motorcycle with an engine displacement not exceeding 50 cm3 and a maximum attainable speed of 48 km/h on a level paved surface, and

      • (ii) Appendix I-1 to subparts D and E, part 205, chapter I, title 40 of the United States Code of Federal Regulations, as amended by Vol. 45, No. 252 of the Federal Register of the United States published on December 31, 1980, at pages 86726 and 86727, the exterior sound level does not exceed 80 dBA, in any other case.

    • SOR/2009-318, s. 16(F).
