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. SIST EN 62087-6:2015

IEC 62087-6:2015 © IEC 2015 – 5 –
– 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. The text of this standard is based on the following documents: FDIS Report on voting 100/2471/FDIS 100/2501/RVD
Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. A list of all parts in the IEC 62087 series, published under the general title Audio, video, and related equipment – Determination of power consumption, can be found on the IEC website. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to the specific publication. At this date, the publication will be • reconfirmed, • withdrawn, • replaced by a revised edition, or • amended. A bilingual version of this publication may be issued at a later date.
– 6 – IEC 62087-6:2015 © IEC 2015 INTRODUCTION This part of IEC 62087 specifies methods of measurements for the power consumption of audio equipment for consumer use. It is used in conjunction with IEC 62087-2, which specifies signals and media. This International Standard includes measurements in the On mode (operation), which was previously identified as “On (average) mode” and adds methods for measuring power consumption in the On-play, On-decoding, and idle sub-modes. These methods consider the effects of the auto power down function. Additionally, this standard includes determination of power consumption in the Partial On mode. This standard has been divided into multiple parts. At the time of publication of this part, the following parts are planned or published. – Part 1: General – Part 2: Signals and media – Part 3: Television sets – Part 4: Video recording equipment – Part 5: Set-top boxes (STB) – Part 6: Audio equipment

DETERMINATION OF POWER CONSUMPTION –
Part 6: Audio equipment
1 Scope This part of IEC 62087 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 standard is limited to audio equipment which can be connected to the mains. Audio equipment that includes a non-removable, main battery is not covered by this standard. Audio equipment may include any number of auxiliary batteries. The measuring conditions in this standard represent the normal use of the equipment and may differ from other specific conditions, for example as specified in safety standards. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
