IEC 62087-6:2015

Audio, video, and related equipment - Determination of power consumption - Part 6: Audio equipment

IEC 62087-6:2015 specifies the determination of the power consumption of audio equipment for consumer use. The various modes of operation which are relevant for measuring power consumption are defined. This first edition of IEC 62087-6 cancels and replaces Clause 9 of IEC 62087:2011. This standard together with IEC 62087-1 to IEC 62087-5 cancels and replaces IEC 62087:2011. This International Standard constitutes a technical revision. This edition includes the following significant technical changes with respect to Clause 9 of IEC 62087:2011. The definition of the input signal is changed. The output power measurement of amplifiers is changed. The measurement method for compact audio systems including loudspeakers is added. Methods for measuring On-decoding, idle and auto power down functions are added. Portions of the document related to general measuring conditions and procedures are now contained in IEC 62087-1:2015. Portions of the document related to signals and media are now in IEC 62087-2:2015. The titles have changed in order to comply with the current directives and to accommodate the new multipart structure of IEC 62087.

Appareils audio, vidéo et matériel connexe - Détermination de la consommation de puissance - Partie 6: Matériel audio

L'IEC 62087-6:2015 spécifie la détermination de la consommation de puissance des matériels audio pour le grand public.
Les différents modes de fonctionnement appropriés à la mesure de la consommation de puissance sont définis.
La présente norme est limitée au matériel audio qui peut être raccordé au réseau d'alimentation électrique. Un matériel audio qui inclut une batterie principale non amovible n'est pas couvert par la présente norme. Un matériel audio peut inclure un nombre quelconque de batteries auxiliaires.
Les conditions de mesure de la présente norme sont celles de l'usage normal du matériel et peuvent différer d'autres conditions, par exemple celles spécifiées dans les normes de sécurité.
L'IEC 62087-6:2015 annule et remplace l'Article 9 de l'IEC 62087:2011. La présente norme, en conjonction avec les IEC 62087-1 à IEC 62087-5, annule et remplace l'IEC 62087:2011. La présente norme constitue une révision technique.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l'Article 9 de l'IEC 62087:2011:
– la définition du signal d'entrée a été modifiée;
– la mesure de la puissance de sortie des amplificateurs a été modifiée;
– la méthode de mesure des systèmes audio compacts qui incluent des haut-parleurs a été ajoutée;
– des méthodes de mesure de marche décodage, attente et des fonctions d'extinction automatique ont été ajoutées;
– les parties du document qui concernent les conditions générales et les modes opératoires de mesure sont désormais contenues dans l'IEC 62087-1:2015;
– les parties du document qui concernent les signaux et les supports se trouvent désormais dans l'IEC 62087-2:2015;
– les titres ont été modifiés afin de se conformer aux directives actuelles et de tenir compte de la nouvelle structure en plusieurs parties de l'IEC 62087.

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 62087-6 has been prepared by technical area 12: AV energy
efficiency and smart grid applications, of IEC technical committee 100: Audio, video and
multimedia systems and equipment.
This first edition of IEC 62087-6 cancels and replaces Clause 9 of IEC 62087:2011. This
standard together with IEC 62087-1 to IEC 62087-5 cancels and replaces IEC 62087:2011.
This International Standard constitutes a technical revision.
This edition includes the following significant technical changes with respect to Clause 9 of
IEC 62087:2011.
– The definition of the input signal is changed.
– The output power measurement of amplifiers is changed.
– The measurement method for compact audio systems including loudspeakers is added.
