标准摘要
[中文适用范围]： 包括相关设备的制造、使用及维护单位，为超声波校准提供了统一的技术依据。 ***此介绍可能不准确，请注意参考原文。 [外文原描述]： IEC 62127-2:2007+A1:2013 specifies absolute hydrophone calibration methods and relative (comparative) hydrophone calibration methods. This standard is applicable to: - hydrophones used for measurements made in water and in the ultrasonic frequency range up to 40 MHz; - hydrophones employing circular piezoelectric sensor elements, designed to measure the pulsed wave and continuous wave ultrasonic fields generated by ultrasonic equipment; - and hydrophones with or without a hydrophone pre-amplifier. IEC 62127-1, IEC 62127-2 and IEC 62127-3 are being published simultaneously. Together these cancel and replace IEC 60866:1987, IEC 61101:1991, IEC 61102:1991, IEC 61220:1993 and IEC 62092:2001. The contents of the corrigendum of August 2008 have been included in this copy. The French version of this standard has not been voted upon. This consolidated version consists of the first edition (2007) and its amendment 1 (2013). Therefore, no need to order amendment in addition to this publication.
