DIN EN 61157
Standard means for the reporting of the acoustic output of medical diagnostic ultrasonic equipment (IEC 61157:2007 + A1:2013); German version EN 61157:2007 + A1:2013
Normverfahren für die Angabe der akustischen Ausgangsgrößen von medizinischen Ultraschalldiagnostikgeräten (IEC 61157:2007 + A1:2013); Deutsche Fassung EN 61157:2007 + A1:2013
Overview
This International Standard is applicable to medical diagnostic ultrasonic equipment. It provides a set of traceable acoustic parameters describing the acoustic fields. It defines a standard means and format for the reporting of the acoustic output information. It also describes a reduced dataset recommended for equipment generating low acoustic output levels. The information tabulated in this standard format can be used for exposure planning for biological effects studies. The standard also describes information on exposure data for prospective epidemiological studies conducted using exposure conditions similar to those reported in this standard. In the absence of actual exposure data for retrospective epidemiological studies, the information tabulated in this standard format can also be used with cautionary comment. The responsible committee is DKE/GUK 821.3 "Medizinische Ultraschallgeräte" ("Medical ultrasound devices") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
