Electroacoustics - Audiometric equipment - Part 7: Instruments for the measurement of auditory evoked potentials (IEC 60645-7:2009)
This part of IEC 60645 applies to instruments designed for the measurement of auditory evoked potentials from the inner ear, the auditory nerve and the brainstem, evoked by acoustic and/or vibratory stimuli of short duration. This part of IEC 60645 defines the characteristics to be specified by the manufacturer, specifies performance requirements for two types of instrument, screening and diagnostic, and specifies the functions to be provided on these types. The purpose of this part of IEC 60645 is to ensure that measurements made under comparable test conditions with different instruments complying with this standard will be consistent. This part of IEC 60645 is not intended to restrict development or incorporation of new features, nor to discourage innovative approaches. The application of electric stimuli for special purposes is beyond the scope of this standard.

Electroacoustique - Appareillage audiométrique - Partie 7: Instruments pour la mesure des potentiels évoqués auditifs (CEI 60645-7:2009)
La CEI 60645-7:2009 s'applique aux instruments conçus pour la mesure audiologique des potentiels évoqués de l'oreille interne, du nerf auditif et du tronc cérébral, évoqués par des stimuli acoustiques et/ou vibratoires de courte durée. La CEI 60645-7:2009 définit les caractéristiques qui doivent être spécifiées par le fabricant, spécifie les exigences de performances pour deux types d'instrument, le dépistage et le diagnostic, et spécifie les fonctions à prévoir sur ces deux types. La CEI 60645-7:2009 est destinée à assurer que les mesures réalisées dans des conditions d'essai comparables avec différents instruments conformes à la présente norme seront cohérentes. La CEI 60645-7:2009 n'est pas destinée à limiter le développement ou l'ajout de nouvelles caractéristiques ni à décourager les approches innovantes. L'application de stimuli électriques pour des usages particuliers n'entre pas dans le domaine d'application de la présente norme.
Elektroakustika - Avdiometrična oprema - 7. del: Instrumenti za merjenje slušnih potencialov (IEC 60645-7:2009)
Ta del IEC 60645 velja za instrumente za merjenje slušnih potencialov notranjega ušesa, slušnega živca in možganskega debla, ki jih izvabijo kratkotrajni akustični in/ali vibracijski dražljaji. Ta del IEC 60645 določa lastnosti, ki jih mora navesti proizvajalec, predpisuje specifikacije zmogljivosti za dve vrsti instrumentov, presejanje in diagnostiko in določa funkcije, ki jih morata ti vrsti izpolnjevati. Namen tega dela IEC 60645 je zagotoviti, da so meritve, ki se opravljajo pod primerljivimi preskusnimi pogoji z različnimi instrumenti v skladu s tem standardom, med seboj skladne. Ta standard ni namenjen ne omejevanju razvoja ali vključevanju novih funkcij ne odvračanju od inovativnih pristopov. Uporaba električnih dražljajev za posebne namene presega področje uporabe tega standarda.

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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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 indire
...
