It is a not-for-profit, nonstatutory, vol
4、untary membership association engaged in standards development and certification activities. CSA standards reflect a national consensus of producers and users including manufacturers, consumers, retailers, unions and professional organizations, and governmental agencies. The standards are used widel

Individuals, companies, and associations across Canada indicate their support for CSAs st

The more than 7000 committee volunteers and the 2000 sustaining memberships together form CSAs total membership from which its Directors are chos

The Association offers certification and testing services in support of and as an extension to its standards development activities. To ensure the integrity of its certification process, the Asso

In addition to its head office and laboratory complex in Toronto, CSA has regional branch offices in major centres across Canada and inspection and testing agencies in eight countries. Since 1919, the Association
9、has developed the necessary expertise to meet its corporate mission: CSA is an independent service organization whose mission is to provide an open and effective forum for activities facilitating the exchange of goods and services through the use of standards, certification and related services to m

11、utonomous organizations working towards the further development and improvement of voluntary standardization in the national interest. The principal objects of the Council are to foster and promote voluntary standardization as a means of advancing the national economy, benefiting the health, safety,
12、 and welfare of the public, assisting and protecting the consumer, facilitating domestic and international trade, and furthering international cooperation in the field of standards. A National Standard of Canada is a standard which has been approved by the Standards Council of Canada and one which r

25、 edition 1987-04-15 Reference number ISO 1996-2: 1987 (E) Foreword ISO (the International Organization for Standardization) is a worldwide federation of national Standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committe
26、es. Esch 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, govern- mental and non-governmental, in liaison with ISO, also take part in the work. Draft International Standards adopte
27、d by the technical committees are circulated to the member bodies for approval before their acceptance as International Standards by the ISO Council. They are approved in accordance with ISO procedures requiring at least 75 % approval by the member bodies voting. International Standard ISO 1996-2 wa

ISO 1996-2 together with ISO 1996-1 : 1982 and ISO 1996-3 : 1987 cancel and replace ISO Recommendation R 1996 : 1971, of which they constitute a technical revision. Users should note that all International Standards undergo revision from time
29、to time and that any reference made herein to any other International Standard implies its latest edition, unless otherwise stated. 0 International Organkation for Standardkation, 1987 Printed in Switzerland INTERNATIONAL STANDARD ISO 1996-2: 1987 (E) Acoustics - Description and measurement of envir
30、o.nmentaI noise - . Part 2 : Acquisition of data pertinent to land use 0 Introduction 0.1 ISO 1996 comprises the following three Parts : Part 1 : Basic quantities and procedures. Part 2 : Acquisition of data pertinent to land use. Part 3 : Application to noise Iimits. 0.2 This part of ISO 1996 descr
31、ibes methods to be used for measuring and describing environmental noise relevant to general land use. The use of different measuring methods, such as continuous integration, sampling techniques and measurements under selected meteorological coriditions, is considered. Calculation methods or scale m
32、odel investigations may also be used. This part of ISO 1996 does not deal in detail with calculation methods. If, however, such methods are used to obtain data pertinent to land use, it is important that the noise be described in a way that is consistent with the requirements of this part of ISO 199
33、6. The purpose of this part of ISO 1996 is to provide methods for the acquisition of data for describing environmental noise. Using these data as a basis, authorities may establish a System for selecting the appropriate land use, as far as levels of noise are concerned, for a specified area, or the
34、sources of noise - existing or planned 7 which are acceptable with respect to land use, existing or planned. This part of ISO 1996 does not give guidance on the estimation of the Overall uncertainty of the results, but this shoutd be considered in each specific case, if possible. lt does not specify
35、 noise limits. 1 Scope and field of application This part of ISO 1996 describes methods for the acquisition of data which provide descriptors that enable a) a description of the environmental noise in a specified area of land to be made in a uniform way; b) the compatibility of any land use activity
36、 or projected activity to be assessed with respect to.existing or predicted noise. 2 References ISO 1996-1, Acoustics - Description and measurement of environmental noise - Part 7 : Basic quantities and procedures. 1 ) IEC Publication 651, Sound level meters.

38、el lies between two specified levels such as, for example, between 65 and 70 d. The noise zone number for this example is 65-70 dB. 3.3 receiver : Person or group of persons who are or who are expected to be exposed to environmentat noise. 4 Acquisition of data . For the purpose of acquisition of da
39、ta relevant to land use, the following basic information is required : a) geographicat description of the area under consider- ation; 1) Cross-references to specific clauses, sub-clauses, etc. in ISO 1996-1 apply to the first edition published in 1982. ISO 1996-2: 1987 (EI b) description of the main
40、 characteristics of the sources of noise pertinent to this area; 6 dB. If the components are only just detectable by the observer and demonstrated by narrow-band analysis, an adjustment of 2 to 3 dB may be appropriate. c) description of the Situation of the receiver, such as location, occupation, us
41、e and features of the immediate surroundings. 4.1.4 Impulse adjustment, KZ If impulse is an essential characteristic of the Sound within a specified time intervat, an adjustment may be applied, for this time interval, to the measured equivalent continuous A-weighted Sound pressure level. The value o
42、f this adjustment shall be stated. NOTE - If possible, information on prevailing meteorological conditions in the area under consideration should be given, preferably as statistical information on wind Speed and direction, on precipitation and temperature (including the occurrence of temperature inv
43、ersions) for a typical time interval, such as a year or any other suitable time interval. NOTES 1 A method of describing the impulse characteristic of the Sound within the specified time interval is to measure the differente between the A-weighted Sound pressure level, determined with time-weightinq
44、 characteristic I averaged over the same time interval, and LAeq r The Sound pressure levels should be determined simultaneousl;. The Character of the noise may be further illustrated by determining the peak level and the number of impulses during a specified time interval. 4.1 Acoustical data 4.1.1
45、 General Basic acoustical data are equivalent continuous A-weighted Sound pressure levels determined over the reference time intervals and rating levels for the same reference time intervals with additional information on the characteristics of the noise, if required. 2 For large-amplitude noise, su
46、ch as the noise generated by sonic booms, mining or quarry blasts, measurements with C-weighting are used in some countries to determine the rating level. 4.1.2 Rating level 4.2 Meteorological adjustment The rating level shall be determined over reference time intervals related to the characteristic
47、s of the source(s) and receiverk). To extrapolate from a value of the equivalent continuous A-weighted Sound pressure levei measured under selected meteorological conditions to a long-term value, a meteoro- logical adjustment may be used (sec 5.3 in ISO 1996-1). The rating level, (LA, given by the f
