Part 1: General
FOREWORD
a) 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.
b) 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.
c) 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.
d) 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.
e) 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.
f) All users should ensure that they have the latest edition of this publication.
g) 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.
h) 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.
i) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s),
which may be required to implement this document. However, implementers are cautioned that this may not
represent the latest information, which may be obtained from the patent database available at
https://patents.iec.ch. IEC shall not be held responsible for identifying any or all such patent rights.
IEC 62087‑1 has been prepared by technical area 19: Environmental and energy aspects for
multimedia systems and equipment, of IEC technical committee 100: Audio, video and
multimedia systems and equipment. It is an International Standard.
The first edition of IEC 62087‑1 together with IEC 62087‑2 to IEC 62087‑6 canceled and
replaced IEC 62087:2011 in its entirety. The first edition of IEC 62087-1 included the following
significant technical changes with respect to Clauses 1 to 5 of IEC 62087:2011:
– new information about operation modes;
– equipment that includes removable main batteries are now considered;
– light measuring equipment is now specified.
This second edition of IEC 62087‑1 cancels and replaces the first edition published in 2015.
This edition constitutes a technical revision and includes the following significant technical
changes with respect to the previous edition:
IEC CDV 62087-1 © IEC 2026
– updated comprehensive set of terms and defintions related functions and modes;
– ILMD is introduced;
– luminance and illuminance meter accuracy requirements are increased;
– power source and power meter references IEC 62301 (ED3), which includes improved
measurement uncertainty specifications;
– introduces a method to determine the screen area.
The text of this International Standard is based on the following documents:

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,

1 Scope
This part of IEC 62087 specifies the general requirements and test equipment for other parts of
IEC 62087. Requirements for specific types of equipment are specified in additional parts of
this standard and may supersede the requirements specified in this part.
Moreover, this part of IEC 62087 defines the different modes of operation which are relevant
for determining power consumption.
This standard is only applicable for equipment which can be powered by an external power
source. Equipment that includes a non-removable main battery is not covered by this standard.
Equipment may include any number of auxiliary batteries.
In order to assess compliance of a specific model of equipment with its declared power value,
a verification procedure for power measurements is provided in Annex B.
