IEC 80601-2-26:2019

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

IEC 80601-2-26:2019 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 electro-convulsive 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.
IEC 80601-2-26:2019 cancels and replaces the third edition of IEC 60601-2-26 published in 2012. This edition constitutes a technical revision to align with Amendment 1:2012 of IEC 60601-1:2005, new versions of collateral standards and amendments thereto.
The contents of the corrigendum of October 2021 have been included in this copy.

Appareils électromédicaux - Partie 2-26: Exigences particulières pour la sécurité de base et les performances essentielles des électroencéphalographes

IEC 80601-2-26:2019 s'applique à la SECURITE DE BASE et aux PERFORMANCES ESSENTIELLES des ELECTROENCEPHALOGRAPHES définis en 201.3.204, aussi appelés APPAREILS EM ou SYSTEMES EM dans la présente norme. Le présent document est applicable aux ELECTROENCEPHALOGRAPHES destinés à être utilisés dans les établissements de soins professionnels, l'ENVIRONNEMENT DES SERVICES MEDICAUX D'URGENCE ou l'ENVIRONNEMENT DES SOINS A DOMICILE.
Les exigences propres à d'autres appareils également utilisés en électroencéphalographie ne relèvent pas du domaine d'application du présent document, par exemple:
– stimulateurs phonophotiques;
– appareils de stockage et restitution d'informations d'EEG;
– APPAREILS EM destinés particulièrement à la surveillance au cours d'une thérapie électro-convulsive.
Si un article ou un paragraphe est spécifiquement destiné à être applicable uniquement aux APPAREILS EM ou uniquement aux SYSTEMES EM, le titre ou le contenu de cet article ou de ce paragraphe l'indique. Si ce n'est pas le cas, l'article ou le paragraphe s'applique à la fois aux APPAREILS EM et aux SYSTEMES EM, comme suit.
L'article ou le paragraphe s'applique aux APPAREILS EM, par défaut. Pour les APPAREILS EM dont la mesure ou la fonction de sécurité correspondante n'est pas complètement intégrée dans l'APPAREIL EM, mais plutôt mise en œuvre dans un SYSTEME EM, le FABRICANT de l'APPAREIL EM spécifie dans les DOCUMENTS D'ACCOMPAGNEMENT les exigences de fonctionnalité et de sécurité qu'assure le SYSTEME EM pour être conforme au présent document. Le SYSTEME EM est vérifié en conséquence.
Les DANGERS inhérents à la fonction physiologique prévue des APPAREILS EM ou des SYSTEMES EM dans le cadre du domaine d'application du présent document ne sont pas couverts par des exigences spécifiques contenues dans le présent document.
IEC 80601-2-26:2019 annule et remplace la troisième édition de l'IEC 60601-2-26 parue en 2012. Cette édition constitue une révision technique destinée à s'aligner sur l'Amendement 1:2012 de l'IEC 60601-1:2005 et sur les nouvelles versions des normes collatérales et leurs amendements.
Le contenu du corrigendum d'octobre 2021 a été pris en considération dans cet exemplaire.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC
Publication(s)"). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International standard IEC 80601-2-26 has been prepared by a Joint Working Group of IEC
subcommittee 62D: Electromedical equipment, of IEC technical committee 62: Electrical
equipment in medical practice, and ISO subcommittee SC3: Lung ventilators and related
