One of the key concepts within IEC 60601-1 is the distinction between Basic Safety and Essential Performance.

Basic Safety

Basic safety refers to protection against unacceptable risks caused directly by physical hazards.

Examples include:

Electric shock
Fire hazards
Excessive temperatures
Mechanical injury
Radiation hazards

Essential Performance

Essential performance refers to the performance characteristics necessary to avoid unacceptable risks to patients or operators.

For example:

A ventilator must continue delivering air correctly.
A patient monitor must display accurate physiological data.
An infusion pump must provide medication at the intended rate.

Loss of essential performance may create significant clinical risks.

Classification of Medical Electrical Equipment

IEC 60601-1 classifies medical equipment according to safety characteristics.

Class I Equipment

Class I devices rely on protective earthing for safety.

Examples include:
