26、 2017 3 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ UNDERWATER ACOUSTICS HYDROPHONES PROPERTIES OF HYDROPHONES IN THE FREQUENCY RANGE 1 Hz TO 500 kHz FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnic
27、al 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 Specifications, T
28、echnical 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. International, gover
29、nmental 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 decisions
30、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 internation
31、al 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 order to
32、 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 clearly
33、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 certification bodie
34、s. 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, property
35、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 in this
36、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 any or a
37、ll such patent rights. International Standard IEC 60500 has been prepared by IEC technical committee 87: Ultrasonics. This second edition cancels and replaces the first edition published in 1974. This edition constitutes a technical revision. This edition includes the following significant technical
38、 changes with respect to the previous edition. a) The format and scope of IEC 60500 have been changed to be compatible with IEC 62127-3:2007 in accordance with ISO/IEC Directives, and has a good conformity with IEC 60565:2006, making the suite of available standards for underwater sound a more coord
39、inated and coherent system. b) The upper limit of the frequency range of hydrophones has been expanded from 100 kHz to 500 kHz. c) Technical requirements of hydrophone selecting are provided in Annex A, and the depth range of the static pressure range of hydrophones has been expanded from 10 m to 10
40、0 m. 4 IEC 60500:2017 IEC 2017 The text of this International Standard is based on the following documents: FDIS Report on voting 87/644/FDIS 87/649/RVD Full information on the voting for the approval of this International Standard can be found in the report on voting indicated in the above table. T
41、his document has been drafted in accordance with the ISO/IEC Directives, Part 2. The committee has decided that the contents of this document will remain unchanged until the stability date indicated on the IEC website under “http:/webstore.iec.ch“ in the data related to the specific document. At thi
42、s date, the document will be reconfirmed, withdrawn, replaced by a revised edition, or amended. IEC 60500:2017 IEC 2017 5 UNDERWATER ACOUSTICS HYDROPHONES PROPERTIES OF HYDROPHONES IN THE FREQUENCY RANGE 1 Hz TO 500 kHz 1 Scope This document specifies the relevant characteristics and properties of h
43、ydrophones in the frequency range 1 Hz to 500 kHz, and specifies how to report these characteristics. It does not cover performance requirements for specific hydrophone types, or for specific hydrophone applications. However, guidance on the choice of a hydrophone with appropriate performance for a
44、specific application is given in an informative annex. This document is applicable to: hydrophones employing piezoelectric sensor elements, designed to respond to sound pressure in water and measure underwater acoustical signals; hydrophones with or without an integral pre-amplifier. 2 Normative ref
45、erences The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments
46、) applies. ISO 266:1997, Acoustics Preferred frequencies 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 angular co-ordinate system system used to designate the directional response pattern of the hydrophone Note 1 to entry: The terms “horizo
47、ntal directional response” and “vertical directional response” are often used for representation of directional response in the xy-plane, and xz- (or yz-) planes respectively. Note 2 to entry: “+z” is coincident with an axis of the hydrophone, and “ z” is in the direction of the hydrophone cable. 6

The end-of cable capacitance is typically measured at a frequency of 1 kHz. 3.3 diffraction factor ratio of the root-mean-square sound pressure averaged over the part of the hydrophone designed to receive an incident plane wave sound pressure from a given direction to the free
