3.7 Electrical Safety Tests
WARNING
z Electrical safety tests are a proven means of verifying the electrical safety of the
patient monitor. They are intended for determining potential electrical hazards.
Failure to find out these hazards timely may cause personnel injury.
z Commercially available test equipment such as safety analyzer, etc. can be used for
electrical safety tests. Be sure that the test equipment can be safely and reliably
used with the patient monitor before use. The service personnel should acquaint
themselves with the use of the test equipment.
z Electrical safety tests should meet the requirements of the new edition of standards
EN 60601-1 and UL60601.
z These electrical safety tests do not supersede local requirements.
z All devices using the AC mains and connected to medical equipment within patient
environments must meet the requirements of the IEC 60601-1 medical electrical
systems standard and should be put under electrical safety tests at the frequency
recommended for the patient monitor.
Electrical safety tests are intended to check if potential electrical hazards to the patient,
operator or service personnel of the equipment. Electrical safety test should be performed
under normal ambient conditions of temperature, humidity and pressure.
The electrical safety test plan described hereafter takes 601 safety analyzer as an example.
Different safety analyzers may be used in different areas. Be sure to choose applicable test
plan.
