16、ization 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 Intern
17、ational 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
18、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 t
19、he 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 ha
20、ve 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 mis
21、interpretation 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 nati
22、onal 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
23、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
24、 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 dr
25、awn 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 no
26、t be held responsible for identifying any or all such patent rights. International Standard IEC 62087-4 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 I
27、EC 62087-4 cancels and replaces Clause 7 of IEC 62087:2011. This standard together with IEC 62087-1 to IEC 62087-3 and IEC 62087-5 to IEC 62087-6 cancels and replaces IEC 62087:2011. This International Standard constitutes a technical revision. This edition includes significant technical changes wit
28、h respect to Clause 7 of IEC 62087:2011. The changes include fundamental and extensive revisions to cover video recorders such as DVD and BD types as well as recorders with removable solid state memory. Clause 7 has been revised in its entirety. 4 IEC 62087-4:2015 IEC 2015 The text of this standard
29、is based on the following documents: FDIS Report on voting 100/2469/FDIS 100/2499/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 Aud
30、io, 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 in
31、dicated 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. IEC 62087-4:2015 I
32、EC 2015 5 INTRODUCTION This part of IEC 62087 specifies methods of measurement for the power consumption of video recording equipment for consumer use. IEC 62087:2011 revises methods for measuring power consumption of set top boxes mainly in the modes of On mode and Standby-active, high mode. These
33、modes correspond to the active modes which are defined in IEC 62542:2013. 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 recordi
34、ng equipment Part 5: Set-top boxes (STB) Part 6: Audio equipment 6 IEC 62087-4:2015 IEC 2015 AUDIO, VIDEO AND RELATED EQUIPMENT DETERMINATION OF POWER CONSUMPTION Part 4: Video recording equipment 1 Scope This part of IEC 62087 specifies methods of measurement for the power consumption of video reco
35、rding equipment with removable media. It specifies the different modes of operation which are relevant for measuring power consumption. The methods of measurement are applicable only for equipment which can be connected to the mains. The measuring conditions in this standard represent the normal use
36、 of the equipment and may differ from specific conditions, as specified, for example, 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.
