Appendix F: 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.
