标准摘要
[中文适用范围]： 建立了完整探测器性能的测量方法、现有设备性能报告的要求、制造商在随附文献中声明设备性能方面的要求 [外文原描述]： Is applicable to ultrasonic Doppler foetal heartbeat detectors which generate a single ultrasound beam and consist of a hand-held probe which is applied to the maternal abdomen to obtain information on foetal heart activity by means of the Doppler method using continuous wave (c.w) or quasi-continuous wave ultrasound. Establishes - methods of measurement of performances - requirements for the performance and the - reporting of performance
