标准范围

IEC 62127-1:20 07规定了使用校准水听器测量液体中由工作在高达40 MHz频率范围内的超声医疗设备产生的声场的方法。本标准的目标是:-定义可以在物理健全的基础上测量的一组声学参数；-定义第二组参数，所述第二组参数可以在某些假设下从这些测量导出，并且被称为导出的强度参数；-定义可用于确定声压参数的测量过程；-定义可以使用校准的水听器在高达40MHz的频率范围内进行声学参数测量的条件；-以及定义用于校正由使用具有有限带宽和有限有源元件尺寸的水听器引起的限制的程序。IEC 62127-1、IEC 62127-2和IEC 62127-3正在同时发布。这些共同取消并取代IEC 60866:1987、IEC 61101:1991、IEC 61102:1991、IEC 61220:1993和IEC 62092:2001。2008年8月更正的内容已列入本副本。该标准的法文版尚未表决。

IEC 62127-1:2007 specifies methods of use of calibrated hydrophones for the measurement in liquids of acoustic fields generated by ultrasonic medical equipment operating in the frequency range up to 40 MHz. The objectives of this standard are:
- to define a group of acoustic parameters that can be measured on a physically sound basis;
- to define a second group of parameters that can be derived under certain assumptions from these measurements, and called derived intensity parameters;
- to define a measurement procedure that may be used for the determination of acoustic pressure parameters;
- to define the conditions under which the measurements of acoustic parameters can be made in the frequency range up to 40 MHz using calibrated hydrophones;
- and to define procedures for correcting, for limitations caused by the use of hydrophones with finite bandwidth and finite active element size. 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.
