English: The maximum sound level expressed in A-weighted decibels (dB(A)) shall be measured to the first decimal place as the vehicle is coasting between lines AA′ and BB′ (figure 1 — front end of the vehicle on line AA′, rear end of the vehicle on line BB′). This value will constitute the result of the measurement. At least four measurements shall be made on each side of the test vehicle at test speeds lower than the reference speed specified in paragraph 4.1 and at least four measurements at test speeds higher than the reference speed.

English: In addition, Table 1 gives some guidelines in order to obtain the desired texture and durability. The grading curve fits the following formula:
Dutch: P (doorlatingspercentage) = 100 · (d/dmax) 1/2
English: where: d square mesh sieve size, in mm
Dutch: d maaswijdte van de vierkante zeefmazen in mm
English: Area When designing the test track layout it is important to ensure that, as a minimum requirement, the area traversed by the vehicles running through the test strip is covered with the specified test material with suitable margins for safe and practical driving.

English: According to Annex 3, paragraph 3.2, measurements have to be made on each side of the vehicle.
