标准简介:This part of ISO 362 specifies an engineering method for measuring the noise emitted by road vehicles of
categories M and N under typical urban traffic conditions. It excludes vehicles of category L1 and L2, which
are covered by ISO 9645, and vehicles of category L3, L4 and L5 covered by ISO 362-2.
The specifications are intended to reproduce the level of noise generated by the principal noise sources
during normal driving in urban traffic (see Annex A).
The method is designed to meet the requirements of simplicity as far as they are consistent with
reproducibility of results under the operating conditions of the vehicle.
The test method requires an acoustical environment that is only obtained in an extensive open space. Such
conditions are usually provided for
⎯ type approval measurements of a vehicle,
⎯ measurements at the manufacturing stage, and
⎯ measurements at official testing stations.
NOTE 1 The results obtained by this method give an objective measure of the noise emitted under the specified
conditions of test. It is necessary to consider the fact that the subjective appraisal of the noise annoyance of different
classes of motor vehicles is not simply related to the indications of a sound measurement system. As annoyance is
strongly related to personal human perception, physiological human conditions, culture and environmental conditions,
there is a large variation and it is therefore not useful as a parameter to describe a specific vehicle condition.
NOTE 2 Spot checks of vehicles chosen at random are rarely made in an ideal acoustical environment. If
measurements are carried out on the road in an acoustical environment which does not fulfil the requirements stated in
this International Standard, the results obtained can deviate appreciably from the results obtained using the specified
conditions.
