Medical electrical equipment - Part 2-66: Particular requirements for the basic safety and essential performance of hearing instruments and hearing instrument systems

Standard applies to the BASIC SAFETY of HEARING INSTRUMENTS and HEARING INSTRUMENT SYSTEMS, hereafter also referred to as ME EQUIPMENT or ME SYSTEM. If a clause or subclause is specifically intended to be applicable to HEARING INSTRUMENTS only, or to HEARING INSTRUMENT SYSTEMS only, the title and content of that clause or subclause will say so. If that is not the case, the clause or subclause applies both to HEARING INSTRUMENTS and to HEARING INSTRUMENT SYSTEMS, as relevant. HAZARDS inherent in the intended physiological function of HEARING INSTRUMENTS or HEARING INSTRUMENT SYSTEMS within the scope of this standard are not covered by specific requirements in this standard except in 201.7.9.2 and 201.9.6. ACCESSORIES to HEARING INSTRUMENTS in the HOME HEALTHCARE ENVIRONMENT (e.g. remote control units, audio streamers, battery chargers, power supplies) are covered by the most applicable standard, IEC 60065, IEC 60950-1 or other applicable IEC safety standards. Alternatively the general standard may be applied. HEARING INSTRUMENTS do not have a MAINS PART intended for connection to a.c. SUPPLY MAINS. The connection to the SUPPLY MAINS of a HEARING INSTRUMENT system is covered by power supply, charger or other types of ACCESSORIES. ACCESSORIES connected to a HEARING INSTRUMENT may form a HEARING INSTRUMENT SYSTEM. Only the HEARING INSTRUMENT and its detachable parts are subject to all applicable clauses of this particular standard. The remaining components of the HEARING INSTRUMENT SYSTEM are subject to requirements of this particular standard that result from their connection to the HEARING INSTRUMENT SYSTEM. Programming interfaces or ACCESSORIES in a clinical application are covered by the general standard.

L'IEC 60601-2-66:2015 s'applique à la sécurité de base des instruments d'audition et des systèmes d'audition, également désignés ci-après par appareil EM ou système EM. Cette deuxième édition annule et remplace la première édition parue en 2012. Cette édition constitue une révision technique visant à adapter l'IEC 60601-2-66:2012 aux corrections techniques introduites par l'Amendement 1 (2012) à l'IEC 60601-1:2005, ainsi qu'à clarifier et à corriger la formulation de cette norme particulière, et à mettre en oeuvre les modifications mineures demandées par les parties intéressées.

Medicinska električna oprema - 2-66. del: Posebne zahteve za osnovno varnost in bistvene lastnosti slušnih pripomočkov in sistemov slušnih instrumentov

Standard se uporablja za OSNOVNO VARNOST SLUŠNIH PRIPOMOČKOV in SISTEMOV SLUŠNIH INSTRUMENTOV (v nadaljevanju tudi: ELEKTROMEDICINSKA OPREMA ali ELEKTROMEDICINSKI SISTEM). Če je poglavje ali podpoglavje namenjeno samo obravnavi SLUŠNIH PRIPOMOČKOV ali SISTEMOV SLUŠNIH INSTRUMENTOV, bo to navedeno v naslovu in besedilu poglavja ali podpoglavja. Če ni navedeno, poglavje ali podpoglavje obravnava SLUŠNE PRIPOMOČKE in SISTEME SLUŠNIH INSTRUMENTOV, kot je primerno. Temeljnih TVEGANJ pri nameravani fiziološki funkciji SLUŠNIH PRIPOMOČKOV ali SISTEMOV SLUŠNIH INSTRUMENTOV, ki spadajo na področje uporabe tega standarda, posebne zahteve tega standarda ne vključujejo, razen v točkah 201.7.9.2 in 201.9.6. PRIKLJUČKI k SLUŠNIM PRIPOMOČKOM, ki se uporabljajo v OKOLJU DOMAČE ZDRAVSTVENE OSKRBE (npr. enote za daljinsko vodenje, avdio pretočniki, polnilniki baterij, električno napajanje), so zajeti v najprimernejšem standardu, standardu IEC 60065, IEC 60950-1 ali drugih primernih varnostnih standardih IEC. Uporabi se lahko tudi splošni standard. SLUŠNI PRIPOMOČKI nimajo OMREŽNEGA DELA za povezavo z izmeničnim NAPAJALNIM OMREŽJEM. Povezava z NAPAJALNIM OMREŽJEM sistema SLUŠNIH INSTRUMENTOV se izvede prek električnega napajanja, polnilca ali drugih PRIKLJUČKOV. PRIKLJUČKI, povezani s SLUŠNIM PRIPOMOČKOM, lahko sestavljajo SISTEM SLUŠNIH INSTRUMENTOV. Vse točke tega standarda veljajo le za SLUŠNI PRIPOMOČEK s snemljivimi deli. Za ostale sestavne dele SISTEMA SLUŠNIH INSTRUMENTOV veljajo zahteve tega standarda, ki zadevajo povezavo s SISTEMOM SLUŠNIH INSTRUMENTOV. Programske vmesnike ali PRIKLJUČKE za klinično uporabo zajema splošni standard.

Coverage of Essential Requirements of EU Directives

This European Standard has been prepared under a mandate given to CENELEC by the European

Commission and the European Free Trade Association to provide a means of conforming to the

Essential Requirements given in Annex I of the EU Directives 93/42/EEC as amended by 2007/47/EC.

General Guidance:

Once this standard will be cited in the Official Journal of the European Union under that Directive,

compliance with the clauses of this standard given in Table ZZ.1 confers, within the limits of the scope

of this standard, a presumption of conformity with the corresponding Essential Requirements (ERs) of

that Directive and associated EFTA regulations.

NOTE 1 This standard is intended to be applied in its entirety only. Selected clauses or

subclauses may be not applicable due to the specific type of equipment under consideration. It is

necessary to understand and apply Clauses 1 to 5. It is also recommended to understand and apply

those clauses which contain general requirements related to a specific subclause. Elements of the

standard that are not cited in Table ZZ.1 may be relevant for the appropriate fulfilment of certain

essential requirements through indirect reference, and for safety and performance aspects of the

device, that are not addressed through essential requirements.

NOTE 2 Where a reference from a clause of this standard to the risk management process is

made, the risk management process needs to be in compliance to the MDD (Directive 93/42/EEC

amended by 2007/47/EC). This means that risks have to be reduced "as far as possible", "to a

minimum", "to the lowest possible level", "minimized" or "removed", according to the wording of the

corresponding essential requirement.

NOTE 3 With respect to Note 4 of 4.2.2 General requirement for risk management, the

manufacturer’s policy for determining acceptable risk must be in compliance with essential

requirements 1, 2, 5, 6, 7, 8, 9, 11 and 12 of the directive.

NOTE 4 References in the Clauses 3 to 17 or in the Annexes of this standard specify whether

the normative references listed in Clause 2 as cited in Annex ZA are to be applied in whole or in part.

NOTE 5 This Annex ZZ is based on Normative References according to Annex ZA, replacing

the references in the core text.

NOTE 6 According to the scope of this standard the coverage in Table ZZ.1 only applies to the

design and construction of HEARING INSTRUMENTS or HEARING INSTRUMENT SYSTEMS. This

European Standard lists in Table ZZ.1 only the essential requirements covered.

WARNING: Other requirements and other EU Directives and Regulations may be applicable to the

product(s) falling within the scope of this standard.
