Ultrasonics. Surgical systems. Measurement and declaration of the basic output characteristics1 Scope This International Standard specifies: the essential non thermal output characteristics of ultrasonic surgical units; NOTE 1 One of the parameters of interest is output acoustic power. This standard addresses only the low frequency (under 100 kHz) component of the total delivered energy. The high frequency component, which probably relates to cavitation developed at the tip, is not addressed (see A. 4). methods of measurement of these output
