32、:2016 IEC 2016 3 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ ELECTROACOUSTICS OCTAVE-BAND AND FRACTIONAL-OCTAVE-BAND FILTERS Part 2: Pattern-evaluation tests FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electr

33、otechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifica

34、tions, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. Internationa

35、l, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal dec

36、isions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for inte

37、rnational use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In o

38、rder to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be c

39、learly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certificatio

40、n bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, pr

41、operty damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited i

42、n this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying a

43、ny or all such patent rights. International Standard IEC 61260-2 has been prepared by IEC technical committee 29: Electroacoustics. This first edition of IEC 61260-2 (together with IEC 61260-1:2014 and IEC 61260-3:2016), cancels and replaces the first edition of IEC 61260 published in 1995 and its A

44、mendment 1 published in 2001. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to IEC 61260. a) The single document in the first edition of IEC 61260:1995 is now separated into three parts of the IEC 61260 series covering:

45、specifications, pattern-evaluation tests and periodic tests. b) IEC 61260:1995 specified three performance categories: class 0, 1 and 2 while the IEC 61260 series specifies requirements for class 1 and 2. c) In IEC 61260:1995, the design goals for the specification can be based on base-2 or base-10

46、design. In the IEC 61260 series only base-10 is specified. BS EN 61260-2:2016 4 IEC 61260-2:2016 IEC 2016 d) The reference environmental conditions have been changed from 20 C/65 % RH to 23 C/50 % RH; e) IEC 61260:1995 specified tolerance limits without considering the uncertainty of measurement for

47、 verification of the specifications. The IEC 61260 series specifies acceptance limits for the observed values and maximum-permitted uncertainty of measurements for laboratories testing conformance to specifications in the standard. The text of this standard is based on the following documents: CDV R

48、eport on voting 29/845/CDV 29/881A/RVC Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all the parts of the IEC 61260 ser

49、ies, published under the general title Electroacoustics Octave-band and fractional-octave-band filters can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC website under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. BS EN 61260-2:2016IE
