Ultrasonics - Hand-held probe Doppler foetal heartbeat detectors - Performance requirements and methods of measurement and reporting

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

Ultraschall - Handgehaltene Doppler-Herzschlagdetektoren für Föten - Leistungsanforderungen sowie Meß- und Angabeverfahren

Ultrasons - Détecteurs des battements de coeur foetal à effet Doppler avec sonde à main - Prescriptions de performance et méthodes de mesure et de signalement

S'applique aux détecteurs ultrasonores des battements de coeur foetal par effet Doppler qui produisent un faisceau ultrasonore unique et qui consistent en une sonde à main appliquée sur l'abdomen maternel pour recueillir des informations sur l'activité du coeur foetal au moyen de la méthode Doppler utilisant des ultrasons à onde entretenue ou quasi-entretenue. Etablit: - des méthodes de mesure des performances - des prescriptions de performance et pour le signalement de ces performances

FOREWORD
The IEC (International Electrotechnical Commission) is a worldwide organization for standardization
1)
comprising all national electrotechnical committees (IEC National Committees). The object of the IEC is to
promote international cooperation on all questions concerning standardization in the electrical and
electronic fields. To this end and in addition to other activities, the IEC publishes International Standards.
Their preparation is entrusted to technical committees; any IEC National Committee interested in
the subject dealt with may participate in this preparatory work. International, governmental and
non-governmental organizations liaising with the IEC also participate in this preparation. The IEC
collaborates closely with the International Organization for Standardization (ISO) in accordance with
conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of the IEC on technical matters, prepared by technical committees on
which all the National Committees having a special interest therein are represented, express, as nearly as
possible, an international con
