9.10 Transducer surface temperature
EN 60601-2-37:2008+A1:2015 according to the requirements of clause 201.11, the
transducer surface temperature was measured under two conditions: transducer
suspension in the absence of air circulation environment (Still Air) and probe contact
phantom (Method B).
The maximum surface temperature and maximum temperature rise of the transducer
are listed below
