Chapter 2
Electrical Safety Tests
The electrical safety tests in this section are based on and conform to IEC 62353 and NFPA 99
1
. They
are intended for electrical safety evaluation of cord-connected, electrically operated, patient care
equipment. If additional information is needed, refer to IEC 62353 and NFPA 99 or the
corresponding Handbook.
The tests summarized in Table 2 should be performed at regular intervals. The suggested interval is
annual or consistent with user site policy.
All tests listed in Table 2 can be done with a Safety Analyzer listed in 1.8 or equivalent.
To connect to the Safety Analyzer, use ACCY-014 Patient Lead Grounding Cable.
To connect to the chassis for leakage tests, connect to the Potential Equalization post on the chassis.
