Section 9-8 - Electrical Safety Tests 9 - 31
9-8-11 Mains on applied part
NOTE: Mains Applied refers to the sink leakage test where mains (supply) voltage is applied to the part to
determine the amount of current that will pass (or sink) to ground if a patient contacted mains voltage.
Mains on applied part is one of the described leakage current tests applicable for probes (Ref:
IEC60601-1). This is to be performed with the probe disconnected from the Ultrasound system. Apply
mains voltage over the insulation barrier. (Between protective earth on the probe connector, and an
electrical anode in saline solution. The patient applied part of the probe is immersed into the saline
solution.) Measure current flowing in the circuit. = leakage current.
As a minimum, tests according to IEC60601-1 must be performed once a year. The requirements for
Body Floating (BF) have to be applied for TEE and Trans thorax probes bearing the symbol for safety
class BF.
The symbol for BF is indicated on the probe connector label below:
Figure 9-13 GE Probe Connector Label example
NOTE: This test is not needed for Type B applied part (example, FibroScan probe).
