The work of preparing International Standards is normally carried out
20、 through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO col
21、laborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different appro
22、val criteria needed for the different types of ISO documents should be noted.

ISO 2015 All rights reserved vBS ISO 362-1:2015ISO 362-1:2015(E)IntroductionAn extensive review was
28、 conducted of actual in-use vehicle operations, beginning with data from the TUV Automotive study in the early 1990s and continuing with data developed through other committee members from 1996 through 2000. It includes nearly 100 vehicles operated on a variety of urban roads in Europe and Asia. The
29、 primary focus of the in-use measurements was to determine how vehicles are driven with a variety of vehicles, driving behaviours, and traffic situations. The in-use behaviour determined from these studies was successfully correlated to urban traffic use in the United States by evaluation of the fue
30、l economy test cycles used by the United States Environmental Protection Agency (USEPA). The resulting test specifications are therefore valid for all global urban use conditions.The procedure defined here provides a measure of the sound pressure level from vehicles under controlled and repeatable c
31、onditions. The definitions have been made according to the requirements of vehicle categories. In cases of vehicles other than very heavy trucks and buses, the working group found that attempts to conduct a partial load test as in actual use resulted in considerable run-to-run variability that signi
32、ficantly interfered with the repeatability and reproducibility of the test cycle. Therefore, two primary operating conditions (i.e. a wide-open-throttle acceleration phase and a constant speed phase) were used to guarantee simplicity. The combination was found to be equivalent to the partial throttl
33、e and partial power (engine load) actually used.As a further consequence of the investigation of the requirements for an efficient test, it was decided to design a test which was independent of vehicle design and therefore safe and adaptable for future technologies, as well as for future traffic con
34、ditions. The test guarantees an excitation of all relevant noise sources, and the final test result reflects a combination of these sources as a compromise between normal urban use and “worst case”.In 2004, the given test for M and N category vehicles was evaluated for technical accuracy and practic
35、al considerations by test programmes carried out by the Japan Automobile Standards Internationalization Center (JASIC), the European Automotive Manufacturers Association (ACEA), and the Society of Automotive Engineers, Inc. (SAE) in the United States. Over 180 vehicles were included in these tests.
36、The reports of these test programmes were considered prior to preparation of this part of ISO 362.This part of ISO 362 was developed following demands for a new test procedure considering the following: “The test procedure (ISO 362) doesnt reflect realistic driving conditions” (1996 EU Green Paper);
37、 “In the case of motor vehicles, other factors are also important such as the dominance of tyre noise above quite low speeds (50 km/h)” (1996 EU Green Paper). “A new measurement procedure should require that the major noise sources of a vehicle be measured” (2001 Noise Emission of Road Vehicles I-IN
38、CE).This edition of ISO 362-1 while maintaining the same technical procedures as the previous edition, has been revised based on practical experience to provide additional clarification, to provide additional equivalent test modes for heavy commercial vehicles, and to incorporate provisions for addr
39、essing hybrid propulsion systems for M1 and N1 category vehicles.vi ISO 2015 All rights reservedBS ISO 362-1:2015Measurement of noise emitted by accelerating road vehicles Engineering method Part 1: M and N categoriesIMPORTANT The electronic file of this International Standard contains colours which
40、 are considered to be useful for the correct understanding of the International Standard. Users should therefore consider printing this International Standard using a colour printer.1 ScopeThis part of ISO 362 specifies an engineering method for measuring the noise emitted by road vehicles of catego
41、ries 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, which are covered by ISO 362-2.The specifications are intended to reproduce the level of noise generated by the principal noise sou
42、rces 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 obtained only
43、 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 sp
44、ecified 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, physiolo
45、gical 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 c
46、arried out on the road in an acoustical environment that does not fulfil the requirements stated in this part of ISO 362, the results obtained can deviate appreciably from the results obtained using the specified conditions.2 Normative referencesThe following documents, in whole or in part, are norm
