Section 10-7

The electrical safety tests in this section are based on and conform to NFPA 99 (For USA) and IEC

60601-1 Medical Equipment Safety Standards. They are intended for the electrical safety evaluation of

cord-connected, electrically operated, patient care equipment. If additional information is needed, refer

to the NFPA 99 (For USA) and IEC 60601-1 documents.

THE USER MUST ENSURE THAT THE SAFETY INSPECTIONS ARE PERFORMED AT

LEAST EVERY 12 MONTHS ACCORDING TO THE REQUIREMENTS OF THE PATIENT

SAFETY STANDARD IEC-EN 60601-1. ONLY TRAINED PERSONS ARE ALLOWED TO

PERFORM THE SAFETY INSPECTIONS MENTIONED ABOVE.

To avoid electrical shock, the unit under test must not be connected to other electrical

equipment. Remove all interconnecting cables and wires. The unit under test must not be

contacted by users or patients while performing these tests.

Possible risk of infection. Do not handle soiled or contaminated probes and other components

that have been in patient contact. Follow appropriate cleaning and disinfecting procedures

before handling the equipment.

Test the system, peripherals and probes for leakage current. Excessive leakage current can cause

injury or death in sensitive patients. High leakage current can also indicate degradation of insulation and

a potential for electrical failure. Do not use probes or equipment having excessive leakage current.

To minimize the risk that a probe may shock someone the customer should:

Not use a probe that is cracked or damaged in any way

Check probe leakage current:
