4、c Tests (a nationally adopted international standard) Secretariat: Acoustical Society of America Approved on July 21, 2014 by: American National Standards Institute, Inc. Abstract ANSI/ASA S1.4-2014/Part 3 / IEC 61672-3:2013 describes procedures for periodic testing of time-weighting, integrating-av
5、eraging, and integrating sound level meters that were designed to conform to the class 1 or class 2 specifications of ANSI/ASA S1.4-2014/Part 1 / IEC 61672-1. The aim of the standard is to ensure that periodic testing is performed in a consistent manner by all laboratories. The purpose of periodic t
6、esting is to assure the user that the performance of a sound level meter conforms to the applicable specifications of ANSI/ASA S1.4-2014/Part 1 / IEC 61672-1 for a limited set of key tests and for the environmental conditions under which the tests were performed. Periodic tests described in this edi
7、tion of ANSI/ASA S1.4-2014/Part 3 / IEC 61672-3 apply to sound level meters for which the manufacturer claims conformance to the specifications of the second edition of ANSI/ASA S1.4-2014/Part 1 / IEC 61672-1. Periodic tests described in ANSI/ASA S1.4-2014/Part 3 / IEC 61672-3 apply to sound level m
8、eters for which the model has been, or has not been, pattern approved by an independent testing organization responsible for pattern approvals in accordance with the test procedures of ANSI/ASA S1.4-2014/Part 2 / IEC 61672-2. Procedures for the periodic testing of sound level meters designed to conf
9、orm to the specifications of IEC 61672-1:2002 were given in IEC 61672-3:2006. AMERICAN NATIONAL STANDARDS ON ACOUSTICS The Acoustical Society of America (ASA) provides the Secretariat for Accredited Standards Committees S1 on Acoustics, S2 on Mechanical Vibration and Shock, S3 on Bioacoustics, S3/SC
10、 1 on Animal Bioacoustics, and S12 on Noise. These committees have wide representation from the technical community (manufacturers, consumers, trade associations, organizations with a general interest, and government representatives). The standards are published by the Acoustical Society of America
11、as American National Standards after approval by their respective Standards Committees and the American National Standards Institute (ANSI). These standards are developed and published as a public service to provide standards useful to the public, industry, and consumers, and to Federal, State, and
12、local governments. Each of the Accredited Standards Committees (operating in accordance with procedures approved by ANSI) is responsible for developing, voting upon, and maintaining or revising its own Standards. The ASA Standards Secretariat administers Committee organization and activity and provi
13、des liaison between the Accredited Standards Committees and ANSI. After the Standards have been produced and adopted by the Accredited Standards Committees, and approved as American National Standards by ANSI, the ASA Standards Secretariat arranges for their publication and distribution. An American
14、 National Standard implies a consensus of those substantially concerned with its scope and provisions. Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected interests. Substantial agreement mea
15、ns much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered and that a concerted effort be made towards their resolution. The use of an American National Standard is completely voluntary. Their existence does not in any respect p
16、reclude anyone, whether he or she has approved the Standards or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the Standards. NOTICE: This American National Standard may be revised or withdrawn at any time. The procedures of the American
17、 National Standards Institute require that action be taken periodically to reaffirm, revise, or withdraw this Standard.

As such, this Foreword may contain material that has not been subjected to public rev
25、iew or a consensus process. In addition, it does not contain requirements necessary for conformance to the standard. This standard comprises a part of a group of definitions, standards, and specifications for use in acoustics. It was developed and approved by Accredited Standards Committee S1 Acoust
26、ics, under its approved operating procedures. Those procedures have been accredited by the American National Standards Institute (ANSI). The Scope of Accredited Standards Committee S1 is as follows: Standards, specifications, methods of measurement and test, and terminology in the field of physical
27、acoustics, including architectural acoustics, electroacoustics, sonics and ultrasonics, and underwater sound, but excluding those aspects which pertain to biological safety, tolerances, and comfort. This nationally adopted international standard is a new standard and does not revise or replace any p
28、re-existing American National Standard. This standard is identical to IEC 61672-3:2013, which was prepared by IEC Technical Committee 29, in cooperation with the International Organization of Legal Metrology (OIML). However, in conformance with ANSI and IEC rules, the words “this part of ANSI/ASA S1
29、.4-2014 / IEC 61672“ replace the words “this part of IEC 61672“ where they appear in the IEC document, decimal points were substituted in place of the decimal commas used in IEC documents, and American English spelling is used in place of British English spelling. This standard includes five Annexes
30、. Annexes B, D and E are normative and are considered to be a part of this standard. Annexes A and C are informative and are not considered part of this standard. The ANSI/ASA equivalents for the IEC standards in the IEC 61672 series are given below: ANSI/ASA S1.4-2014/Part 1 / IEC 61672-1:2013 is a
31、n identical national adoption of IEC 61672-1:2013. ANSI/ASA S1.4-2014/Part 2 / IEC 61672-2:2013 is an identical national adoption of IEC 61672-2:2013. ANSI/ASA S1.4-2014/Part 3 / IEC 61672-3:2013 is an identical national adoption of IEC 61672-3:2013. This nationally adopted international standard is
32、 one of three standards that, taken together, revise and replace ANSI S1.4-1983 (R 2006), ANSI S1.4A-1985 (R 2006) and ANSI S1.43-1997 (R 2007).

36、1.4-2014/Part 3 / IEC 61672-3 describes procedures for periodic testing of time-weighting, integrating-averaging, and integrating sound level meters that were designed to conform to the class 1 or class 2 specifications of the second edition of IEC 61672-1. The aim of the standard is to ensure that
37、periodic testing is performed in a consistent manner by all laboratories. NOTE 1 In this document, references to IEC 61672-1, IEC 61672-2, and IEC 61672-3 refer to the second editions unless stated otherwise. U.S. INFORMATIVE NOTE In this document, references to IEC 61672-1, IEC 61672-2, and IEC 616
38、72-3 refer to the three parts of ANSI/ASA S1.4-2014 / IEC 61672:2013. See the list provided in the Foreword. NOTE 2 Procedures for the periodic testing of sound level meters designed to conform to the specifications of IEC 61672-1:2002 were given in IEC 61672-3:2006. The purpose of periodic testing
39、is to assure the user that the performance of a sound level meter conforms to the applicable specifications of IEC 61672-1 for a limited set of key tests and for the environmental conditions under which the tests were performed. The extent of the tests in this part of ANSI/ASA S1.4 / IEC 61672 is de
40、liberately restricted to the minimum considered necessary for periodic tests. Periodic tests described in this edition of ANSI/ASA S1.4/Part 3 / IEC 61672-3 apply to sound level meters for which the manufacturer claims conformance to the specifications of the second edition of IEC 61672-1. Periodic
41、tests described in this part of ANSI/ASA S1.4 / IEC 61672 apply to sound level meters for which the model has been, or has not been, pattern approved by an independent testing organization responsible for pattern approvals in accordance with the test procedures of the second edition of IEC 61672-2.
42、Because of the limited extent of the periodic tests, if evidence of pattern approval is not publicly available, no general conclusion about conformance to the specifications of IEC 61672-1 can be made, even if the results of the periodic tests conform to all applicable requirements of this edition o
