YY/T 1089-2007Electroacoustic characteristics and measurement methods of single element pulse-echo ultrasonic transducers (English PDF)

YY/T 1089-2007 is the English-translated version of 单式脉冲回波超声换能器的基本电声特性和测量方法.

YY/T 1089-2007 sets out, for the Chinese medical device industry, the electroacoustic characteristics of single element pulse-echo ultrasonic transducers and the methods used to measure them.

It gives the terms and definitions for these transducers and then the basic electroacoustic characteristics together with their measurement methods.

It applies to piezoelectric single element pulse-echo transducers used for combined transmission and reception, with an effective radiating diameter of not more than 30 mm and a working frequency range of 1 MHz to 10 MHz.

The cited standards are GB 3102.7-1993, GB/T 3238-1982 and GB/T 3947-1996. The document replaces YY/T 91089-1999. Issued on 31 January 2007, it has applied since 1 January 2008.
