      NAC 484D.180  Noise emission measurements: Operation of new vehicles. (NRS 484D.410)  New motor vehicles tested for compliance with NAC 484D.155, together with any auxiliary equipment that would be in use while the vehicle is in motion on the highway, must be operated as follows:

     1.  Trucks, truck-tractors and buses that have a manufacturer’s gross vehicle weight rating of 6,000 pounds or more must be operated under the condition of grade, load, acceleration, deceleration and gear selection that is found to give the maximum noise at a speed up to 35 miles per hour.

     2.  Trucks, truck-tractors and buses that have a gross vehicle weight rating of less than 6,000 pounds and passenger cars must be tested at curb weight plus weight of the driver and when necessary one technician, and be operated as follows:

     (a) Motor vehicles equipped with three-speed or four-speed manual transmissions must be operated in second gear. Vehicles equipped with four-speed manual transmissions must also be operated in second gear. Vehicles equipped with five-speed manual transmissions must be operated in second gear. Vehicles equipped with automatic transmissions must be operated with transmissions engaged in low gear. Vehicles which reach maximum rated engine speed at less than 30 miles per hour or before reaching a point 25 feet beyond the microphone line must be operated in the next highest gear. Auxiliary step-up ratios or overdrive must not be engaged on vehicles so equipped.

     (b) The vehicle must proceed along the test path at a constant approach speed of 30 miles per hour. When the front of the vehicle reaches a point 25 feet from a line through the microphone intersecting the path of the vehicle at right angles, the throttle must be fully opened. The throttle must be held open until the rear of the vehicle is approximately 100 feet beyond the microphone, or until the maximum rated engine speed is obtained at which point the throttle is gradually closed. Wheel slip must be avoided during this test.

     3.  Motorcycles must be operated as follows:

     (a) Motorcycles must be operated in second gear. Vehicles which reach maximum rated engine speed at less than 30 miles per hour or before reaching a point 25 feet beyond the microphone line must be operated in the next higher gear.

     (b) The vehicle must proceed along the test path at a constant approach speed which corresponds to either an engine speed of 60 percent of maximum rated engine speed or at 30 miles per hour, whichever is lower. When the front of the vehicle reaches a point 25 feet from a line through the microphone intersecting the path of the vehicle at right angles, the throttle must be fully opened. The throttle must be held open until the rear of the vehicle is approximately 100 feet beyond the microphone, or until the maximum rated engine speed is obtained at which point the throttle is gradually closed. Wheel slip must be avoided during this test.

     4.  Deceleration tests must be conducted on vehicles when there is an indication that the deceleration noise might exceed the acceleration noise. The vehicle must proceed along the test path in the gear which was used for the acceleration test and at a constant approach speed equal to the maximum rated engine speed. When the front of the vehicle reaches a point 25 feet beyond a line through the microphone, the throttle must be closed as rapidly as possible.

      NAC 484D.185  Noise emission measurements: Vehicle noise level. (NRS 484D.410)  The measured noise level of a vehicle must be reported as follows:

     1.  The sound level reading for determining compliance with NAC 484D.150 must be the highest reading obtained as the vehicle or combination of vehicles passes through the measuring site on the highway. Sound level readings must be recorded on vehicles which are in lanes of travel with centerlines at or beyond 50 feet and which produce noise levels exceeding the regulatory limits.

     2.  The sound level readings for determining compliance of new motor vehicles with NAC 484D.155 must be obtained by making at least four measurements for each side of the vehicle. Sufficient preliminary runs must be made to familiarize the driver with the operation of the vehicle and to stabilize the engine operating condition. The A-weighted sound level for each side is the average of the two highest readings on that side which are within 2 dB of each other. The noise level reported for the vehicle must be the sound level of the loudest side of the vehicle. Obvious vehicle malfunction nullifies the test.

     3.  Tolerances are necessary due to unavoidable variations in test site, vehicle operation, test equipment, temperature and wind gradients, and inherent differences in nominally identical vehicles. Vehicles specified in NAC 484D.150 may not be considered in violation unless they exceed the limits in that section by more than 2 dB. New vehicles must be designed to comply with the limits in NAC 484D.155 at the time of manufacture to ensure that the vehicles will not exceed those limits plus a 2 dB tolerance when tested by an enforcement agency.

The yellow-orange fluorescent triangle is for daylight identification. The reflective border defines the shape of the fluorescent color in daylight and becomes a hollow red triangle in the path of motor vehicle headlights at night.

Lr =   illumination incident upon receiver at observation point, foot-candles

Ls =   illumination incident upon a plane perpendicular to the incident ray at the test specimen position, foot-candles

d   =   distance from test specimen to source of illumination (100 ft. as specified in SAE J594), feet

A  =   area of test surface, square feet

 

     5.  The reflective and fluorescent materials must be tough, flexible and of sufficient thickness and strength to meet the requirements of this section and NAC 484D.270. After the durability test, the fluorescent and reflective material must show no appreciable discoloration, cracking, crazing, blistering, loss of durable bond or dimensional change.
