标准范围

IEC 60565-2:20 19规定了水听器在0.01 Hz至几千赫兹频率下的低频压力校准方法，具体取决于校准方法。IEC 60565-2:20 19与IEC 60565-1一起取代了2006年发布的IEC 60565第二版。本版构成技术修订版。IEC 60565-2:20 19相对于上一版本包括以下重大技术变更。1）IEC 60565分为两部分:？第1部分:自由场校准程序；？第2部分:低频压力校准程序（本文件）。2）第8条增加了相对校准方法:压电补偿校准。3）第11条:振动柱校准增加了相对校准方法。4）第12条:增加了静压传感器校准。5）附录A:振动柱校准用激励系统的等效电路，已删除。6)子条款9.6、9.7和9.8已被移动以形成新的附录A:高级声耦合器校准方法。

IEC 60565-2:2019 specifies the methods for low frequency pressure calibration of hydrophones at frequencies from 0,01 Hz to several kilohertz depending on calibration method.
IEC 60565-2:2019, together with IEC 60565-1, replaces the second edition of IEC 60565 published in 2006. This edition constitutes a technical revision.
IEC 60565-2:2019 includes the following significant technical changes with respect to the previous edition.
1) IEC 60565 has been divided into two parts:
？ Part 1: Procedures for free-field calibration;
？ Part 2: Procedures for low frequency pressure calibration (this document).
2) A relative calibration method has been added to Clause 8: Calibration by piezoelectric compensation.
3) A relative calibration method has been added to Clause 11: Calibration by vibrating column.
4) Clause 12: Calibration by static pressure transducer, has been added.
5) Annex A: Equivalent circuit of the excitation system for calibration with a vibrating column, has been deleted.
6) Subclauses 9.6, 9.7 and 9.8 have been moved to form a new Annex A: Advanced acoustic coupler calibration methods.
