Appendix E: Transducer Maximum Surface Temperature
According to the requirements of the section 201.11 in the standard IEC60601-2-37:2007/AMD1:2015, 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 calculation of the expanded uncertainty is
based on the ISO Guide tout ye Expression of uncertainty in measurement. Three transducer samples have
been tested and the confidence coefficient is at 95%,the value of t.975 is 4.30.
The measurement data were obtained under the test conditions employed at CHISON.
