Medical electrical equipment - Part 2-26: Particular requirements for the basic safety and essential performance of electroencephalograph

201.1 Scope, object and related standards 
Clause 1 of the general standard1 applies, except as follows: 

201.1.1 * Scope 
Replacement: 
This part of the 80601 International Standard applies to the BASIC SAFETY and 
ESSENTIAL PERFORMANCE of ELECTROENCEPHALOGRAPHS as defined in 201.3.204, hereafter also referred to as ME EQUIPMENT or ME SYSTEM. This document is applicable to ELECTROENCEPHALOGRAPHS intended for use in professional healthcare facilities, the EMERGENCY MEDICAL SERVICES ENVIRONMENT or the HOME HEALTHCARE ENVIRONMENT. 

This document does not cover requirements for other equipment used in 
electroencephalography such as: 
– phono-photic stimulators; 
– EEG data storage and retrieval; 
– ME EQUIPMENT particularly intended for monitoring during electroconvulsive therapy. 

If a clause or subclause is specifically intended to be applicable to ME EQUIPMENT only, or to ME SYSTEMS only, the title or content of that clause or subclause will say so. If that is not the case, the clause or subclause applies both to ME EQUIPMENT and to ME SYSTEMS, as follows. 

The clause or subclause applies to ME EQUIPMENT, as default. For ME EQUIPMENT with the corresponding safety measure or function not completely integrated into the ME EQUIPMENT but instead implemented in an ME SYSTEM, the ME EQUIPMENT MANUFACTURER specifies in the ACCOMPANYING DOCUMENTS which functionality and safety requirements are provided by the ME SYSTEM to comply with this document. The ME SYSTEM is verified accordingly. 

HAZARDS inherent in the intended physiological function of ME EQUIPMENT or ME SYSTEMS within the scope of this document are not covered by specific requirements in this document.
