J.2 Transducer Maximum Surface Temperature
According to the requirements of the section 201.11 in the standard IEC 60601-2-37: 2015, the
transducer surface temperature has been tested in two kinds of conditions: the transducer suspended
in still air or transducer contacting human-tissue mimicking material.
The measurement data were obtained under the test conditions employed at Mindray.
