10-6-2 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 w
ill pass (or sink
) to ground if a patient contacted
mains volt
age.
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.
