10-12 Section 10-6 - Electrical Safety Tests
10-6-2 GEMS Leakage Current Limits
The following limits are summarized for IEC 60601-1 Medical Equipment Safety Standards. These limits
are GEMS standards and in some cases are lower than the above standards listed.
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.
The following tests are performed at the factory and should be performed at the site. These tests are:
chassis leakage current, and probe leakage current. All measurements are made with an electrical
safety analyzer which should be calibrated and compliant with AAMI/ESI 1993 or IEC 60601 or AS/NZS
3551.
