GEMS Leakage Current Limits

The following limits are summarized for NFPA 99 (For USA) and 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:
grounding continuity, chassis leakage current, probe leakage current, and ECG leakage current. All
measurements are made with an electrical safety analyzer Model 600/600E built by Dale Technology
Corporation or equivalent device.
